1
00:00:06,720 --> 00:00:10,230
Clinton's startling new.

2
00:00:15,160 --> 00:00:27,350
So this is today we will it is our first day in the advanced topic, why we are going to advance topics.

3
00:00:27,370 --> 00:00:38,720
This is day one since it was planned for today to start creating custom reports and exploring the traffic

4
00:00:38,830 --> 00:00:44,320
chart, since these two topics are not ready to deliver.

5
00:00:44,350 --> 00:00:53,640
It is requiring data entry to show the result as a chart and reports so it is not ready to deliver.

6
00:00:53,650 --> 00:00:58,160
These two topics will come back to these topics once they are ready.

7
00:00:58,630 --> 00:01:04,060
The other three topics you are all working with currencies implementing.

8
00:01:07,390 --> 00:01:15,890
Terms of implementing content pagination, these three point twenty one twenty two twenty three are

9
00:01:15,890 --> 00:01:18,540
dependent on topic number nine.

10
00:01:18,560 --> 00:01:25,220
So we have to deliver number nine and go back to this twenty one, twenty 23 three.

11
00:01:25,640 --> 00:01:30,650
So that's why today we start the first topic in the advance of the.

12
00:01:32,170 --> 00:01:34,610
But OK, this is expen.

13
00:01:36,140 --> 00:01:43,140
So that's why maybe some of you are asking why we start advancing topics today.

14
00:01:43,460 --> 00:01:46,480
So this is why I give the reason.

15
00:01:47,210 --> 00:01:54,860
So if you have questions on previous topics, so if you have any questions, please let me know before

16
00:01:54,860 --> 00:01:56,210
starting the today's.

17
00:01:57,390 --> 00:01:58,640
Anyone have questions?

18
00:02:02,660 --> 00:02:07,670
OK, OK, so, Karen, can you start today's topics, please?

19
00:02:08,810 --> 00:02:09,980
Yes.

20
00:02:11,870 --> 00:02:14,300
OK, thank you, Mummy, for explaining that.

21
00:02:15,200 --> 00:02:20,580
I saw I saw an e-mail from emails from some of us who wanted the clarification.

22
00:02:20,600 --> 00:02:21,830
Thank you for the clarification.

23
00:02:23,130 --> 00:02:23,510
Yeah.

24
00:02:23,510 --> 00:02:28,990
So the item number nine that Mummy is talking about is on advanced topics.

25
00:02:29,000 --> 00:02:31,190
It's working with the bootstrap theme.

26
00:02:31,190 --> 00:02:33,980
So we need to first of all, he's told our theme.

27
00:02:35,340 --> 00:02:41,760
Let me show my screen so that we can be together.

28
00:02:44,400 --> 00:02:49,980
So we have to we have to, first of all, install the bootstrap them.

29
00:02:50,220 --> 00:02:56,760
Number nine, the item that I have highlighted so that we can be able to do you on air routing, working

30
00:02:56,760 --> 00:02:59,820
with currencies and implementing content.

31
00:03:01,050 --> 00:03:07,320
But item number 24, the front page ad and custom reports, we are going to take that when we have the

32
00:03:07,320 --> 00:03:09,230
data ready so that we explore the web.

33
00:03:10,410 --> 00:03:17,880
So today we are going to look at working with comptrollers Aughrim and Escadrille in Froben and also

34
00:03:17,880 --> 00:03:18,840
in Europeanised.

35
00:03:19,380 --> 00:03:25,770
And this is one of the most important things in in actually not only in Europe next of Rapid, but in

36
00:03:25,770 --> 00:03:29,630
in the programming language or any framework that you want to learn.

37
00:03:30,060 --> 00:03:36,030
You need to understand how controllers work because controllers is what carries the logic of the whole

38
00:03:36,030 --> 00:03:38,940
application wiring.

39
00:03:39,240 --> 00:03:43,980
And it's a real fear of of interacting with the database.

40
00:03:44,760 --> 00:03:47,460
And yeah, basically interacting.

41
00:03:47,460 --> 00:03:51,590
The data is either getting the data from them or storing data into the database.

42
00:03:52,110 --> 00:03:58,380
Then, of course, now once you get the data from the database, you, you manipulate that data using

43
00:03:58,380 --> 00:03:59,240
the controllers.

44
00:03:59,880 --> 00:04:05,550
And then the other thing is what the controllers do is when you get data from the users, the data is

45
00:04:05,550 --> 00:04:07,800
received into the controllers.

46
00:04:08,220 --> 00:04:13,530
If there is any need to process the data, it is processed and then it is stored into the database.

47
00:04:14,040 --> 00:04:18,900
Either you also need to do that via Aughrim or Esquibel, whichever you prefer.

48
00:04:20,160 --> 00:04:21,930
So this is what you are going to be doing today.

49
00:04:25,040 --> 00:04:26,540
I go to our instanced.

50
00:04:27,760 --> 00:04:31,590
And I have done something here in our article liberally.

51
00:04:34,370 --> 00:04:41,840
At the Library of People library, I have got something something here, but even before before we go

52
00:04:41,840 --> 00:04:49,670
to what I have done here, or maybe I should explain to you that what we want to achieve in what I have

53
00:04:49,670 --> 00:04:51,740
done here, I have added two things.

54
00:04:53,170 --> 00:05:01,390
The first one is this checkbook's here that is reading truck by us and.

55
00:05:02,430 --> 00:05:09,510
Truck by, so I have had enough both just below our first column where we head to the post again, this

56
00:05:09,510 --> 00:05:12,780
I feel that we added, I have added succubi us.

57
00:05:13,050 --> 00:05:18,810
And ideally what what I am doing with this is just for the purpose of this training I want.

58
00:05:18,960 --> 00:05:25,920
When this cheque book is Checkbook's is checked, we can be able to track the buyers who have purchased

59
00:05:25,950 --> 00:05:32,460
this particular item or who, assuming that this item is for sale, we want to be able to track the

60
00:05:32,460 --> 00:05:34,380
people who have bought it.

61
00:05:34,830 --> 00:05:41,150
And so what they have done, I have added this child table below.

62
00:05:41,550 --> 00:05:46,190
Our articles are DOCTYPE, which is reading by us.

63
00:05:46,200 --> 00:05:51,500
So ideally I created a chart table, not a turntable, but adopted.

64
00:05:51,930 --> 00:05:57,540
So if I go to the police, you'll see here that they have another paper that I have created inside of

65
00:05:57,540 --> 00:05:59,820
our module called the Buyer.

66
00:06:00,480 --> 00:06:03,410
And this duct tape is our third table.

67
00:06:03,450 --> 00:06:07,890
So remember, if you need to do this, if you need to create a charitable, you have to check this.

68
00:06:07,890 --> 00:06:13,680
Checkbook's allowing your application to treat this particular DOCTYPE as adjustable.

69
00:06:15,060 --> 00:06:19,560
And then I have other Driffield just for our testing today, the full name, the email and the phone

70
00:06:19,560 --> 00:06:19,990
number.

71
00:06:20,400 --> 00:06:23,240
And that is what we can see here, full name and phone number.

72
00:06:23,250 --> 00:06:24,980
So I have connected those two.

73
00:06:25,740 --> 00:06:30,120
So I would like this thing to work if this checkbox is not checked.

74
00:06:30,180 --> 00:06:37,430
So if Tilak bias is not checked, ideally we are not supposed to be tracking by us inside of this article.

75
00:06:37,800 --> 00:06:39,360
And therefore you cannot add.

76
00:06:39,570 --> 00:06:45,210
Biagio, if you try to add that via here, then the system after you try to save the system is going

77
00:06:45,210 --> 00:06:52,560
to give you a message and a warning that instead of this DOCTYPE, we can't track bias.

78
00:06:53,190 --> 00:06:59,820
And if you check this checkbox you have allowed this doctor to track by us and now you can add as many

79
00:06:59,820 --> 00:07:01,380
bios here as we want.

80
00:07:01,770 --> 00:07:04,110
So we are going to be seeing how to implement that today.

81
00:07:05,460 --> 00:07:13,350
Before we go there, let us go to our let's go to our instance here.

82
00:07:15,900 --> 00:07:21,980
Close this, increase the font and see how are going to do this.

83
00:07:21,990 --> 00:07:26,640
This is our instance that is running on the other tab so we can leave it running and we can work on

84
00:07:26,640 --> 00:07:27,070
this one.

85
00:07:28,020 --> 00:07:33,040
So how do you get to the how do you get how do you try to interact with them?

86
00:07:33,600 --> 00:07:39,840
Some of us who are Python developers, we know how important the Python shell is.

87
00:07:40,350 --> 00:07:42,030
It's like our daily life.

88
00:07:42,030 --> 00:07:47,760
It is where we go when we need to to test the things and see whether they are lacking even before we

89
00:07:47,760 --> 00:07:56,640
put them into our application and how we do that instead of wrapping it up and doing console and console.

90
00:07:56,640 --> 00:08:03,000
And sometimes if you have multiple sites, you may need to specify the site so you can do Bankside.

91
00:08:03,810 --> 00:08:10,530
I think ours is frappé training and then Brynn's console repetition doesn't exist.

92
00:08:10,800 --> 00:08:12,810
OK, I misspelled frappé.

93
00:08:13,230 --> 00:08:14,670
So this is proper training.

94
00:08:15,720 --> 00:08:17,190
I mean say the console.

95
00:08:17,610 --> 00:08:24,570
So if you have multiple sites, let me exit here because we have one site we are able to do the console

96
00:08:24,720 --> 00:08:25,610
and this beeswax.

97
00:08:26,280 --> 00:08:32,280
But if you have multiple sites into your existence, for instance, if you have a production instance,

98
00:08:32,280 --> 00:08:39,780
it's likely very highly, very likely that you're going to be having multiple, multiple sites in application.

99
00:08:39,780 --> 00:08:41,970
And therefore, this command will be helpful.

100
00:08:42,630 --> 00:08:48,260
We will be needing to specify the sites that you want to access from the from the console.

101
00:08:48,450 --> 00:08:50,280
So is going to this.

102
00:08:52,330 --> 00:08:52,930
Console.

103
00:08:54,310 --> 00:08:57,280
So this is the dream.

104
00:08:57,410 --> 00:09:07,330
So I have my console here, and if we need to start working with this, not only this this duct tape,

105
00:09:07,630 --> 00:09:10,840
we can import it inside of our console.

106
00:09:10,840 --> 00:09:17,830
And remember, having logged in here, let me clear this so that we have some room having logged in

107
00:09:17,830 --> 00:09:18,400
here.

108
00:09:19,090 --> 00:09:24,580
Inside of this basically means I have access now to all the duct tape inside of that.

109
00:09:24,940 --> 00:09:28,990
So I may not need to import them here like we normally do in jungle or other python.

110
00:09:28,990 --> 00:09:36,460
Three months I we already have, Avita, so I can see something like that because of course because

111
00:09:36,460 --> 00:09:40,330
equals and then I do frappé don't get don't get it.

112
00:09:40,350 --> 00:09:44,140
OK, remember it's it's a function that we use to get the documents.

113
00:09:45,360 --> 00:09:51,240
In this one, I told you, I think that they expect to Parramatta's the first parameter is the name

114
00:09:51,240 --> 00:09:52,020
of your duct tape.

115
00:09:52,620 --> 00:10:04,860
Our duct tape here is a particle optical particle library into the second parameter is the primary key

116
00:10:04,860 --> 00:10:06,860
of the article that you want to access.

117
00:10:07,140 --> 00:10:13,740
So I am going to split this so that I, first of all, get the primary key of my article, at least

118
00:10:13,740 --> 00:10:16,800
one article that I want to if I want to access.

119
00:10:18,820 --> 00:10:26,740
And I'm going to do this one is in Karani, so we need to go to our bench use, so we need to do some

120
00:10:26,920 --> 00:10:37,600
pseudo soup and we switch and we provide a password and we can go to bench and training and we can do

121
00:10:37,600 --> 00:10:38,340
a bench.

122
00:10:38,350 --> 00:10:44,650
Maria, be remember, this is the other commands that you can use to access your database.

123
00:10:44,680 --> 00:10:46,870
This is the this is the Esquibel section.

124
00:10:48,160 --> 00:10:50,500
And with that, I have I have my instance.

125
00:10:50,740 --> 00:10:56,470
I have my thumb opened up here and I can try to see what is in this what we have here.

126
00:10:57,750 --> 00:11:09,090
As a primary key, so I can do select select name from and because if a person is here, this this,

127
00:11:09,090 --> 00:11:11,160
of course, will not be prevented with the tab.

128
00:11:11,610 --> 00:11:17,880
And because we have our piece I remember I mentioned this because we have our space in between the name

129
00:11:17,880 --> 00:11:19,830
of our our DOCTYPE here.

130
00:11:19,890 --> 00:11:21,420
We will need to supply a.

131
00:11:22,210 --> 00:11:31,080
Yeah, but this is those people that are using that are using Linux that are not on MapQuest.

132
00:11:31,080 --> 00:11:35,420
It is to the farthest end of your screen to the left, just below the Sipkin.

133
00:11:35,910 --> 00:11:40,310
So if you try to use you try to use our single, he is not going to work.

134
00:11:40,320 --> 00:11:41,760
I think it is not going to work.

135
00:11:42,270 --> 00:11:42,840
You are not.

136
00:11:42,840 --> 00:11:44,210
You need to use a bucket.

137
00:11:44,850 --> 00:11:54,570
And here we see we have very articles in the name which ERP next and treats as the primary key by default

138
00:11:54,930 --> 00:11:55,920
has these three.

139
00:11:55,920 --> 00:11:59,200
So we can get something like this article name.

140
00:12:00,220 --> 00:12:10,320
I copy this and then we bring it to our, to our, our query placed it there and then we run it.

141
00:12:10,950 --> 00:12:13,250
And you see this as this is successful.

142
00:12:13,440 --> 00:12:16,200
If we don't get an error, that means this thing is successful.

143
00:12:16,530 --> 00:12:21,060
So if we try to do articles, we copy this command and we we sit down here.

144
00:12:21,540 --> 00:12:23,150
We should get some articles.

145
00:12:23,160 --> 00:12:23,550
Yeah.

146
00:12:23,550 --> 00:12:26,040
So we see this one is is an object.

147
00:12:26,610 --> 00:12:30,300
We our article and the name of the article is this article.

148
00:12:30,810 --> 00:12:39,240
This test article is what we have is what we have is what we have here is what we have, which is what

149
00:12:39,240 --> 00:12:39,930
we have.

150
00:12:43,050 --> 00:12:43,840
Is what we have here.

151
00:12:43,860 --> 00:12:44,860
This is the test article.

152
00:12:45,420 --> 00:12:49,500
So if we need, for instance, how do we get out?

153
00:12:49,500 --> 00:12:55,150
We have that this article, how do we get the children, the children inside of that this article?

154
00:12:55,200 --> 00:12:56,480
This is very, very important.

155
00:12:57,450 --> 00:12:59,940
Up next, in Europe, it handles it differently.

156
00:13:00,150 --> 00:13:08,460
If we need to get it from our Aughrim here, we can just do something like Atticus, which is the variable

157
00:13:08,460 --> 00:13:11,550
we have here, not the name of our talented people.

158
00:13:11,570 --> 00:13:13,610
Many of the people here is by us.

159
00:13:14,040 --> 00:13:19,620
So if we do if we do that, don't by us, we should get our article here.

160
00:13:19,630 --> 00:13:23,340
And yes, we have one item inside of this.

161
00:13:23,520 --> 00:13:26,880
And how do we precisely see what is inside here?

162
00:13:27,180 --> 00:13:34,410
We can look we can do a loop that that loops through all the items we have here and extract each of

163
00:13:34,410 --> 00:13:34,680
them.

164
00:13:34,980 --> 00:13:38,760
So just like we do in Numberplate, when we can just come here ordinary, by then we can just come here

165
00:13:38,770 --> 00:13:47,880
and see for article in byas articles to buy us.

166
00:13:49,300 --> 00:13:54,220
Remember, this is the name of the variable used here, because this variable contains everything when

167
00:13:54,220 --> 00:14:01,420
we pick this this thing has everything inside of this article, whether it is on the on the part here

168
00:14:01,960 --> 00:14:04,210
or it is down here that's on the table.

169
00:14:04,540 --> 00:14:10,510
This is this particular variable has everything you need.

170
00:14:10,510 --> 00:14:15,370
So we can see for Addicott in this print.

171
00:14:16,690 --> 00:14:19,210
And we want to print what we want to print article.

172
00:14:20,870 --> 00:14:21,950
You can copy this.

173
00:14:22,970 --> 00:14:31,400
Article dot, something like we can do article the full name, we see what we have here, so article

174
00:14:31,400 --> 00:14:34,950
don't fool and ask him what we have.

175
00:14:35,270 --> 00:14:36,440
Free community, good.

176
00:14:36,650 --> 00:14:39,490
So free community is what we have down here.

177
00:14:39,770 --> 00:14:43,340
So if you wanted the email or the phone number, we can do likewise.

178
00:14:43,340 --> 00:14:52,060
We can just get this email and like that to be able to access everything that is inside of our chat

179
00:14:52,070 --> 00:14:52,350
table.

180
00:14:53,280 --> 00:14:58,300
Now that is that is inside our that is inside the console here.

181
00:14:58,360 --> 00:15:01,850
Now, there is one thing that I want to point out very, very, very, very clearly.

182
00:15:02,750 --> 00:15:09,500
Europeanised does not handle relationships the way we are used to handling them, hopefully hoping that

183
00:15:09,500 --> 00:15:13,000
you have you you handle them the way we used to do here.

184
00:15:14,060 --> 00:15:22,400
If you go to the application here and we open our instance training, we are expecting that when we

185
00:15:22,400 --> 00:15:27,680
look at this doctype IDOC that we have here, this is the parent.

186
00:15:27,740 --> 00:15:31,990
So this, these things are children, so they depend on this one.

187
00:15:32,360 --> 00:15:38,210
We are expecting that inside of this parent we have like maybe our primary key or maybe something like

188
00:15:38,390 --> 00:15:39,350
our foreign key.

189
00:15:39,350 --> 00:15:39,540
Yeah.

190
00:15:39,560 --> 00:15:43,180
Our foreign key here with the children.

191
00:15:43,280 --> 00:15:46,750
But unfortunately in frappé that is, that is not how they do it.

192
00:15:47,210 --> 00:15:56,540
So if we go to our Artecoll Library table, we can be and look for the article I Braly article brought

193
00:15:56,570 --> 00:15:58,130
is here and we open it.

194
00:15:59,420 --> 00:16:02,720
We are expecting that we are going to see something related to bias here.

195
00:16:03,260 --> 00:16:07,420
But there is nothing like that if you are not going to find it here.

196
00:16:08,210 --> 00:16:16,340
And so there is no way you can get relationships off your child table from the parents, from the parents

197
00:16:16,340 --> 00:16:16,700
table.

198
00:16:17,390 --> 00:16:20,960
You can also do this by describing you if you don't have access to this.

199
00:16:21,110 --> 00:16:27,530
I haven't personally installed my admin on my on my local machine, so I am able to access both.

200
00:16:28,070 --> 00:16:33,620
But my imagination is that are going to be doing this on Asaba, which you do not need to load with

201
00:16:33,620 --> 00:16:34,760
all these applications.

202
00:16:35,390 --> 00:16:40,640
So how I also wanted to show you how you do that inside of you are here.

203
00:16:40,640 --> 00:16:46,250
If you need to see if you need to see all you need, of course, you need to see this in you to remind

204
00:16:46,250 --> 00:16:52,880
yourself we have a command like you describe, which you can use to check to check what is in tables.

205
00:16:53,270 --> 00:16:56,900
So recommend you describe, for instance, if we do tab.

206
00:16:58,670 --> 00:17:08,710
Article, the Vatican Library Library is letting me down today.

207
00:17:10,310 --> 00:17:17,120
So, yeah, you can see we do not have the same things we are seeing here are the exact same things

208
00:17:17,120 --> 00:17:20,790
we will see when we look at the structure of this table.

209
00:17:21,140 --> 00:17:28,280
So what we have as a structure of this table here is exactly what we are going to see here on the description

210
00:17:28,280 --> 00:17:28,930
of this table.

211
00:17:29,330 --> 00:17:32,620
So you can you can just break that down around to see where there is.

212
00:17:33,110 --> 00:17:39,080
So this if you look clearly, you see like a field parent here, we are going to see it on the next

213
00:17:39,080 --> 00:17:39,510
table.

214
00:17:40,220 --> 00:17:48,500
We also have parent food type parent food, and then we have parents full time, but we do not have

215
00:17:48,500 --> 00:17:49,360
the children.

216
00:17:49,820 --> 00:17:52,050
So there is no child inside of this table.

217
00:17:52,430 --> 00:17:53,340
So how do we get there?

218
00:17:53,360 --> 00:18:00,380
Is there a reason ships are gotten using the name, which is the primary key of the parent table?

219
00:18:01,280 --> 00:18:06,410
The primary key of the parents table, which is by default name, is what is used to describe their

220
00:18:06,680 --> 00:18:12,410
relationships and therefore if we open our BASTABLE here.

221
00:18:12,420 --> 00:18:20,770
So let me go here and look for our BASTABLE bank by the EU, by us based here.

222
00:18:21,770 --> 00:18:23,810
If we look at this table, we describe it.

223
00:18:24,050 --> 00:18:25,760
We also have these three.

224
00:18:25,760 --> 00:18:26,930
We have the appearance.

225
00:18:27,260 --> 00:18:29,620
We have the parent, the type.

226
00:18:29,930 --> 00:18:34,400
And we when we browse, just check those reviews and see what we have.

227
00:18:34,820 --> 00:18:38,290
We have a parent in this time period data.

228
00:18:38,570 --> 00:18:45,500
When we got back to our article, table parent does not have anything because this table is not used

229
00:18:45,500 --> 00:18:47,910
as a table for any table for any doctor.

230
00:18:47,990 --> 00:18:53,690
So parent is now beginning to feel this now and the parent type is now.

231
00:18:54,200 --> 00:19:01,360
But when we come here, parent has data, Bradfield has data and parent type also has data.

232
00:19:02,150 --> 00:19:09,890
So the parent type here contains the name of the DOCTYPE, which is the parent of our table.

233
00:19:10,760 --> 00:19:19,790
The the parent field is the table, not the table, but the field inside of our parents parents table

234
00:19:20,300 --> 00:19:21,620
that is there.

235
00:19:21,620 --> 00:19:23,390
It is done with this table.

236
00:19:26,520 --> 00:19:32,970
So if you come to your appearance, if you come to your parents table, that is the parent table tracked

237
00:19:32,970 --> 00:19:33,380
by us.

238
00:19:33,480 --> 00:19:34,440
Yeah, that is one.

239
00:19:36,570 --> 00:19:39,240
And let me see whether I will get this field.

240
00:19:40,880 --> 00:19:42,810
Now, where is this field?

241
00:19:44,930 --> 00:19:45,380
So.

242
00:19:47,370 --> 00:19:51,860
All I'm looking for a different field here.

243
00:19:53,250 --> 00:20:02,040
Yeah, OK, so so we can look for that later, then the parent here now, this parent is their primary

244
00:20:02,040 --> 00:20:05,900
key, the primary key instead of your parent table.

245
00:20:06,090 --> 00:20:09,640
So the parent type contains the name of the doctor.

246
00:20:09,780 --> 00:20:10,590
In this case.

247
00:20:10,800 --> 00:20:12,590
It is our article.

248
00:20:12,600 --> 00:20:15,510
I brought it here, our article, I really don't think.

249
00:20:15,990 --> 00:20:20,650
And then there is a ship is found inside of their parents.

250
00:20:21,050 --> 00:20:27,780
So any doctor that will define will have at least these to there is the parent and there is a parent

251
00:20:27,780 --> 00:20:28,070
type.

252
00:20:28,560 --> 00:20:32,800
Parent type is the name of the adoptive parent is the primary key.

253
00:20:32,970 --> 00:20:35,790
So, for instance, here we have this is this article.

254
00:20:36,030 --> 00:20:41,070
If you come back here and you scroll back, this is not this article, this latest article.

255
00:20:41,070 --> 00:20:50,730
So it means this article, this particular article here, this particular relationship here is a child

256
00:20:50,850 --> 00:20:53,800
of this this article.

257
00:20:54,000 --> 00:20:56,160
So it is outside of this article here.

258
00:20:56,610 --> 00:21:02,910
And likewise, this one test article, Nim is a child.

259
00:21:03,210 --> 00:21:09,350
This Article Nim, this article name is a child of the first the first article we have here.

260
00:21:09,570 --> 00:21:17,160
So that is how the relationships are defined inside of relationships, ideally are found inside of the

261
00:21:17,160 --> 00:21:20,400
children, the children, they are not in their parents.

262
00:21:20,610 --> 00:21:28,770
So get the child stable and then are able to get all the dog types that are related with that particular

263
00:21:29,220 --> 00:21:32,930
child inside of this parent type field here.

264
00:21:33,390 --> 00:21:37,230
I don't know whether this anyone who has a question up to that point before we proceed.

265
00:21:43,200 --> 00:21:50,030
Garani, can you create a child table with two records and see the result, two records.

266
00:21:53,760 --> 00:22:03,070
So you mean I create to like I add, for instance, here we have our article, this article.

267
00:22:04,230 --> 00:22:09,420
You mean I add another Biagio?

268
00:22:10,560 --> 00:22:12,080
Yes, it's another record.

269
00:22:12,090 --> 00:22:12,450
Yes.

270
00:22:13,080 --> 00:22:25,380
Let me add like I mean, I don't want to names to test the email is then here we have something, just

271
00:22:25,380 --> 00:22:29,930
a random number and we can go ahead and save.

272
00:22:30,390 --> 00:22:31,590
This does not.

273
00:22:32,010 --> 00:22:34,140
So you see this the logic we are going to implement.

274
00:22:34,170 --> 00:22:37,350
So let me first of all, check this so that he accepts that.

275
00:22:38,010 --> 00:22:38,670
So, yeah.

276
00:22:38,940 --> 00:22:43,440
So now if we come here to the table in the record, we have this.

277
00:22:43,770 --> 00:22:46,740
What we have here is this detail here.

278
00:22:46,740 --> 00:22:53,250
We have articulable, which is the name of our DOCTYPE, and then here we have the name, the primary

279
00:22:53,250 --> 00:22:59,590
key of the article, which is the parent of this article we just created here.

280
00:23:00,060 --> 00:23:03,230
So here we have this article name and here we have this article.

281
00:23:03,370 --> 00:23:08,340
So these two belong to the same, the same the same article here.

282
00:23:10,500 --> 00:23:10,810
Mommy.

283
00:23:12,580 --> 00:23:20,470
So the relation is on the child, not the parent, correct, correct, correct, or the relationships

284
00:23:20,470 --> 00:23:23,290
or the relationships are going to be so in the parent table here.

285
00:23:23,290 --> 00:23:25,810
Even if I report, there's nothing that has been added.

286
00:23:27,190 --> 00:23:29,590
There's nothing that has come inside of this table.

287
00:23:29,950 --> 00:23:35,710
Everything is being tracked inside of this this table, this table, the child table.

288
00:23:36,460 --> 00:23:46,300
So they will catch it will catch the idea of the parent table, the parent, the parent I.D. and the

289
00:23:46,300 --> 00:23:47,200
parent column.

290
00:23:48,920 --> 00:23:57,620
Yeah, yeah, correct, sort the parent column inside of the chart table contains the primary key of

291
00:23:57,620 --> 00:23:59,550
the periodic table.

292
00:23:59,850 --> 00:24:00,240
Yes.

293
00:24:00,650 --> 00:24:01,550
So which is the name?

294
00:24:02,280 --> 00:24:02,600
Yeah.

295
00:24:02,870 --> 00:24:06,880
And the other column go the timetable for the child.

296
00:24:07,610 --> 00:24:10,810
The parent feel this is what is bias.

297
00:24:10,820 --> 00:24:12,620
What is this bias.

298
00:24:12,740 --> 00:24:17,810
So parental field parent food here ideally carries the name of our dog.

299
00:24:17,990 --> 00:24:20,780
So you see our duct tape here is caught by us.

300
00:24:20,780 --> 00:24:21,380
Where is it?

301
00:24:24,000 --> 00:24:25,620
Fields, no, not yet.

302
00:24:26,010 --> 00:24:27,000
I need to be here.

303
00:24:28,290 --> 00:24:30,650
Down here, you see the name of this one is by us.

304
00:24:30,900 --> 00:24:35,040
So if you go to the description of this table, let me just do that.

305
00:24:35,550 --> 00:24:37,430
Let me zoom out here a little bit.

306
00:24:37,770 --> 00:24:47,370
If you go to you with customized, customized and you scroll down to where we have that bias, you see

307
00:24:47,370 --> 00:24:51,720
the name, the name, the name of this table is by us.

308
00:24:51,720 --> 00:24:53,280
And that is not is what is taught.

309
00:24:53,730 --> 00:24:59,060
That is what is taught inside of inside of the child, the table, the parent field.

310
00:24:59,280 --> 00:25:05,760
So the parent field is the name of the child, the table here, which in our case is by us.

311
00:25:07,470 --> 00:25:14,340
So this is first time we saw this type of you music, the type statement.

312
00:25:14,610 --> 00:25:16,950
Can you explain more at this table?

313
00:25:18,750 --> 00:25:19,360
Sure, sure.

314
00:25:19,590 --> 00:25:27,040
So what I did, what I did hear, ideally, first of all, I created this duct tape.

315
00:25:27,710 --> 00:25:30,370
Let me take this thing here and see.

316
00:25:31,200 --> 00:25:36,660
So I have saved this and let me remove this one.

317
00:25:37,140 --> 00:25:38,690
Remove and see.

318
00:25:41,230 --> 00:25:48,580
OK, so I created this duct tape for now, this duct tape we have is a very standard duct tape, just

319
00:25:48,590 --> 00:25:50,820
library management and it is called Biya.

320
00:25:51,220 --> 00:25:53,470
And now we have these three fields here.

321
00:25:54,790 --> 00:26:00,610
I go to my to the other table where I do the duct tape where I will not connect to the table.

322
00:26:00,970 --> 00:26:04,750
And I add a room and I call this roll by us.

323
00:26:06,380 --> 00:26:10,480
And then this one is direct.

324
00:26:10,550 --> 00:26:20,120
This is a table table, if you try to save first of all, this is going to tell you the options link

325
00:26:20,360 --> 00:26:23,410
and thiebaud require you to give options.

326
00:26:24,170 --> 00:26:31,350
So if you select if you select here that an item is a table or it is a link, you definitely want to

327
00:26:31,370 --> 00:26:35,730
provide items here, options here because it needs to connect to another doctor.

328
00:26:36,260 --> 00:26:40,270
So we want to connect us to buyer thereby we just created here.

329
00:26:40,280 --> 00:26:47,120
So can we do buy a here save again this winter through an error is telling you that the buyer is not

330
00:26:47,120 --> 00:26:47,860
at the table.

331
00:26:48,020 --> 00:26:56,360
So whatever you provide here as an option will need to be to be connected to the table if you have a

332
00:26:56,360 --> 00:26:56,880
table here.

333
00:26:57,140 --> 00:27:01,870
So that is why in our BASTABLE, we will definitely need to select is charitable here.

334
00:27:01,880 --> 00:27:04,940
So we need to check this check box and then see if it.

335
00:27:06,070 --> 00:27:11,460
And then we when we have that we know is they take that and we try to update our field, this one receives.

336
00:27:12,070 --> 00:27:19,000
So you are duct tape, the duct tape that you want to use as a charitable must have this is charity

337
00:27:19,010 --> 00:27:19,630
project.

338
00:27:20,260 --> 00:27:26,470
And then in your opinion, to DOCTYPE, you need to just select the type of this field is that table

339
00:27:26,830 --> 00:27:30,400
and then you provide here, just like we are doing when we were drinking.

340
00:27:30,850 --> 00:27:37,060
You provide here the duct tape name, which you need to link to our is it is via and then you update

341
00:27:37,060 --> 00:27:38,020
it and that's it.

342
00:27:38,020 --> 00:27:38,530
You are done.

343
00:27:42,380 --> 00:28:00,020
And it's clear now, so I have a I can not cut to this question actually in ERP next, it is not recommended

344
00:28:00,440 --> 00:28:03,280
to make it child of a child.

345
00:28:03,590 --> 00:28:11,660
Is it correct that currently this approach or this intimate understanding?

346
00:28:15,420 --> 00:28:19,080
I told of a child, you mean a child support of another child?

347
00:28:20,120 --> 00:28:20,400
Yes.

348
00:28:22,410 --> 00:28:24,190
Yes, I think so.

349
00:28:24,240 --> 00:28:26,620
I don't have a definite answer now, but I think so.

350
00:28:26,640 --> 00:28:28,980
I'm trying to figure out the youth case.

351
00:28:30,540 --> 00:28:34,740
I'm trying to think of a case that you someone who may be needing to do that.

352
00:28:35,900 --> 00:28:44,160
Suppose your buyer, for example, your buyer and the child would go to the front end, go to Fronton.

353
00:28:45,610 --> 00:28:50,890
Is here what is the biodata child even?

354
00:28:53,100 --> 00:28:57,750
Let me let me go back to sorry, let me bring you can pay article.

355
00:29:02,310 --> 00:29:09,150
Yeah, so, yes, make for the view from view of the charitable form of you.

356
00:29:10,520 --> 00:29:15,650
Full view of the line from a viewer for the line it did president.

357
00:29:17,060 --> 00:29:19,800
Use here instead of one inmate.

358
00:29:20,360 --> 00:29:22,760
Suppose I have many emails.

359
00:29:23,370 --> 00:29:23,910
OK.

360
00:29:24,050 --> 00:29:27,170
And this is a personal email.

361
00:29:27,200 --> 00:29:33,950
This is what I will not add more fields, but I want to add the timetable here to catch.

362
00:29:34,640 --> 00:29:36,700
Suppose I have one hundred email.

363
00:29:37,310 --> 00:29:39,050
I said I am saying anything.

364
00:29:40,220 --> 00:29:49,580
And so this e-mail to catch them, I have to insert here a child table under this rule number one to

365
00:29:49,580 --> 00:29:50,840
catch e mails.

366
00:29:50,840 --> 00:29:57,440
So I have to adro this is a one add another row inmate, too, and so on.

367
00:29:58,700 --> 00:30:09,650
This is the kind of use case where we can do a child of a child or suppose it's very common in buying

368
00:30:09,650 --> 00:30:10,880
and buying a module.

369
00:30:11,340 --> 00:30:20,960
If you buy, for example, laptops, laptops, 10 laptops, and these 10 laptops will be split between

370
00:30:20,960 --> 00:30:21,770
departments.

371
00:30:22,130 --> 00:30:27,760
So finance will get five laptops and each child will get another five laptops.

372
00:30:28,190 --> 00:30:36,200
So in the purchase order line will say, I will buy their laptops, but you have to catch the charge

373
00:30:36,200 --> 00:30:41,460
account to or to consume the budget of each department.

374
00:30:41,810 --> 00:30:48,610
So you need to put whether you have to add two lines in the pictures of the two lines.

375
00:30:48,650 --> 00:30:56,600
So it's quantity which goes to the department or you will group them in one line and put.

376
00:31:00,040 --> 00:31:07,050
You will group them in one line and you will put different distribution in under the for each line,

377
00:31:07,060 --> 00:31:14,530
I will put, for example, H.R. and Tynan's, this is a common use case we will use to consume budget.

378
00:31:14,920 --> 00:31:18,100
Depends on the laptops given to each department.

379
00:31:18,580 --> 00:31:20,010
So here it's a use case.

380
00:31:20,020 --> 00:31:21,160
It's really this case.

381
00:31:23,470 --> 00:31:25,480
Is it doable in the first?

382
00:31:29,160 --> 00:31:37,050
In your opinion, I'm looking at the document here which says it is not doable and I'm trying to think

383
00:31:37,920 --> 00:31:43,530
through minute to minute, minute to minute to minute, minute to minute, and ships will not solve

384
00:31:43,530 --> 00:31:44,120
the problem.

385
00:31:46,100 --> 00:31:48,470
No, it's one too many.

386
00:31:51,450 --> 00:31:54,990
OK, no, no issue, go ahead in your next.

387
00:31:56,590 --> 00:32:01,440
So for the other attendees, if you have a question on previous.

388
00:32:03,510 --> 00:32:07,200
Point, can you have questions?

389
00:32:11,130 --> 00:32:16,230
So from what I understand is, can you open to be my edman?

390
00:32:21,740 --> 00:32:31,210
Yeah, so can you open this and defend to the next step is my Head the Time article.

391
00:32:32,840 --> 00:32:33,900
Yeah, this one, right.

392
00:32:34,790 --> 00:32:43,190
So what I understand is it was on display here, what is the timetable or what are the time difference

393
00:32:43,200 --> 00:32:43,490
here?

394
00:32:43,500 --> 00:32:50,510
But the instance that is the entry, the bias, we will have the display.

395
00:32:50,660 --> 00:32:52,630
What is the primary key?

396
00:32:52,820 --> 00:32:53,300
Right.

397
00:32:54,790 --> 00:32:55,410
Yes.

398
00:32:56,710 --> 00:33:02,650
So so basically, the point of this entire explanation was that all the child tables will contain the

399
00:33:02,650 --> 00:33:07,490
primary, but the parent table, it won't display any child tables, right?

400
00:33:07,930 --> 00:33:08,620
Absolutely.

401
00:33:09,820 --> 00:33:10,300
All right.

402
00:33:11,460 --> 00:33:14,010
I can work on.

403
00:33:22,350 --> 00:33:22,830
Good.

404
00:33:22,860 --> 00:33:25,110
So I'm hopeful that is now clear.

405
00:33:29,230 --> 00:33:36,670
OK, OK, so if you have understood that now the next thing, Mummy, I'm going to do some research

406
00:33:36,670 --> 00:33:40,800
on the child of a child if it is not possible.

407
00:33:40,810 --> 00:33:45,370
I also find try to find a way of our way of getting it working.

408
00:33:45,370 --> 00:33:46,320
I get your use case.

409
00:33:46,330 --> 00:33:47,290
It is very practical.

410
00:33:47,290 --> 00:33:51,790
You may use you may have a user here who has multiple email addresses.

411
00:33:51,830 --> 00:33:53,160
Yeah, it's very, very practical.

412
00:33:53,440 --> 00:33:56,680
So I'll try to see how we can that can be implemented.

413
00:33:58,280 --> 00:34:03,210
So then got one more thing is this.

414
00:34:04,040 --> 00:34:11,540
Yeah, so so what exactly are you achieving by including the track, by irruption?

415
00:34:13,310 --> 00:34:19,970
So what I was doing here, this is for the purposes of this this training, this may not make sense

416
00:34:19,970 --> 00:34:27,770
in the real world, but I was assuming that you are having articles that are for sale and for some reason,

417
00:34:27,770 --> 00:34:35,540
you want to track the people who buy your article in some articles and you don't need to track in other

418
00:34:35,540 --> 00:34:36,120
articles.

419
00:34:36,560 --> 00:34:38,300
So here we can check.

420
00:34:38,300 --> 00:34:39,620
We can have our checkbooks.

421
00:34:40,160 --> 00:34:48,350
This checkbooks will not work until we write some logic to tell it that if this one is checked, then

422
00:34:48,350 --> 00:34:50,760
we want to track buyers for this particular article.

423
00:34:51,020 --> 00:34:55,810
And therefore, when we come down here, we can be able to add buyers here.

424
00:34:56,330 --> 00:35:02,870
If this one is not checked, then we don't need to track articles here and therefore we don't want to

425
00:35:02,870 --> 00:35:04,250
add any articles here.

426
00:35:05,450 --> 00:35:11,330
Now, this this case can be, can be, can be, can, can be, sometimes be very important in real world.

427
00:35:12,110 --> 00:35:21,620
For instance, you want an action in one field to to affect the kind of actions that can be taken on

428
00:35:21,620 --> 00:35:29,820
other fields, like you may be needing to make a field mandatory depending on another field.

429
00:35:29,840 --> 00:35:38,600
So these are field that exists in this field is not mandatory until when other field is checked.

430
00:35:39,530 --> 00:35:45,590
So this kind of logic that we will be writing today will help you be able to do those kind of things.

431
00:35:46,370 --> 00:35:53,180
The other thing that I want to to to to show you with this kind of example here is remember, when you

432
00:35:53,180 --> 00:36:01,160
are doing the the topics, were you able to access these fields from the front end just by getting the

433
00:36:01,180 --> 00:36:06,390
document and then getting the document, the the name that you want to get?

434
00:36:07,070 --> 00:36:08,420
Now, how about the back end?

435
00:36:08,430 --> 00:36:14,780
How about we want to get this field and we want to manipulate another field from the back end using

436
00:36:14,780 --> 00:36:15,410
this data?

437
00:36:16,190 --> 00:36:17,980
That is that is what I want us to look at.

438
00:36:18,470 --> 00:36:22,820
And when you look at our topic for today, they are talking about control and we are still going there

439
00:36:23,200 --> 00:36:27,380
or aim is what we have been doing for them is where is it?

440
00:36:27,380 --> 00:36:28,270
Is what we have been doing.

441
00:36:28,280 --> 00:36:31,790
I think I removed that with Frappé to get Doc.

442
00:36:32,450 --> 00:36:35,400
And then we also have Escorial ask you.

443
00:36:35,450 --> 00:36:38,840
It is what we have been doing here is, is what we have been doing here.

444
00:36:39,890 --> 00:36:45,920
So remember, like I said, in the production environment, you may not be able to access this.

445
00:36:46,460 --> 00:36:48,520
You may not be able to access, which we might admit.

446
00:36:48,890 --> 00:36:54,110
So you may be needing you may need to be very conversant with what happens here and checking the relationships

447
00:36:54,500 --> 00:37:01,040
using the commander in the command line in this case is our is our skill sets that we are going to use

448
00:37:01,040 --> 00:37:01,310
here.

449
00:37:01,760 --> 00:37:07,940
Like, you know, here we just described that the top article, I brought it here, we can go ahead

450
00:37:07,940 --> 00:37:11,870
and do the same for we can go ahead and do the same for for the top.

451
00:37:12,680 --> 00:37:14,360
What is it called bya.

452
00:37:16,170 --> 00:37:21,870
By at least one, this one does not have a space, we don't need to we don't need to add, we don't

453
00:37:21,870 --> 00:37:24,810
need to add batiks in here.

454
00:37:24,810 --> 00:37:26,100
We can see the same things.

455
00:37:26,100 --> 00:37:29,130
We can see the same things that we have on the other.

456
00:37:29,130 --> 00:37:29,910
On the other.

457
00:37:30,240 --> 00:37:33,360
When we check the we might admit.

458
00:37:33,720 --> 00:37:35,160
So this is very important.

459
00:37:37,470 --> 00:37:39,080
Abdoul, I don't know the answer to your question.

460
00:37:43,150 --> 00:37:47,600
Yeah, great, great, great.

461
00:37:47,830 --> 00:37:49,810
Anyone else who needs a qualification?

462
00:37:53,070 --> 00:38:03,630
OK, all right, so now this this is for the purposes of our testing, so how now do we radiologic to

463
00:38:03,630 --> 00:38:10,820
tell our application that when we have these deject, we want we want to track by us and when we have

464
00:38:10,820 --> 00:38:14,700
we checked, don't accept a bias to be added here?

465
00:38:15,900 --> 00:38:22,560
Well, this is done inside of our control as instead of our controllers and controllers in Frappier,

466
00:38:23,340 --> 00:38:26,430
every time you create everything, you create the.

467
00:38:27,780 --> 00:38:34,260
Every time you create a new drug tape, there are things that are generated, really, they may increase

468
00:38:34,260 --> 00:38:34,980
the font

469
00:38:37,800 --> 00:38:40,080
that we remember.

470
00:38:40,080 --> 00:38:45,150
We created a couple number of dog tapes when we were doing our library up.

471
00:38:46,650 --> 00:38:51,600
And we have a folder here that contains all our dog tapes, so.

472
00:38:52,940 --> 00:39:00,170
Our daughter, Pia, has attacked liberally biased what we treated earlier today or today, library

473
00:39:00,250 --> 00:39:03,120
in Mumbai and all these others, and we want to work.

474
00:39:04,070 --> 00:39:07,160
We want to work specifically with Article eight.

475
00:39:07,160 --> 00:39:11,260
But I don't want to talk specifically article.

476
00:39:11,960 --> 00:39:19,970
So when you open this, this will not in DOCTYPE, you have the tipi file that you have there or they

477
00:39:19,970 --> 00:39:21,230
are two by default.

478
00:39:21,560 --> 00:39:22,550
Ignore the test one.

479
00:39:22,580 --> 00:39:26,470
This one is used for automated testing so you can leave that that alone.

480
00:39:27,200 --> 00:39:34,700
The article library file that you have there is what takes handles all our controls.

481
00:39:35,240 --> 00:39:42,200
And remember, we had no idea we had this function that we wrote here that we're supposed to do something

482
00:39:42,200 --> 00:39:43,790
before it receives the document.

483
00:39:44,150 --> 00:39:48,650
It all supposed to do something at the end and also give us a message.

484
00:39:49,760 --> 00:39:54,020
Today, we are going to write another function inside of our article.

485
00:39:54,020 --> 00:39:59,740
Every class that is supposed to do something before this evening is done.

486
00:40:00,260 --> 00:40:02,660
And this one is we have a function Tramadol.

487
00:40:02,750 --> 00:40:07,040
This one is a method because it is a function inside of of a class.

488
00:40:08,080 --> 00:40:12,940
We have a method that has done that is code to validate this one.

489
00:40:13,340 --> 00:40:21,640
I'm sure you found it in the documentation and it runs very deep runs before this is done because ideally

490
00:40:22,040 --> 00:40:23,570
validity is supposed to run.

491
00:40:24,320 --> 00:40:34,310
Take the data that is inside of your form here in the validated across the different validations that

492
00:40:34,310 --> 00:40:35,240
we have provided.

493
00:40:35,510 --> 00:40:42,830
And then if the validations pass, then the thing goes ahead and tries to check before what is false.

494
00:40:42,830 --> 00:40:46,280
Even then, the logic flow continues.

495
00:40:47,340 --> 00:40:54,080
So the family dysfunction takes in self and remember self here.

496
00:40:55,210 --> 00:41:01,210
We are inside of a class, so every time you define a function and pass self, this self is going to

497
00:41:01,210 --> 00:41:03,950
take the whatever is in the class.

498
00:41:04,000 --> 00:41:13,240
So this in our case here for for today is going to contain the article library DOCTYPE and therefore

499
00:41:13,240 --> 00:41:14,140
we do this self.

500
00:41:14,410 --> 00:41:16,060
We are able to do a lot of things here.

501
00:41:18,260 --> 00:41:26,690
If we pick if we take itself, if we take self growth, you can see all the things that we able to do

502
00:41:26,690 --> 00:41:33,920
to do it ourselves here, including the including the name of you, can you can explore this on your

503
00:41:33,920 --> 00:41:34,230
own.

504
00:41:34,640 --> 00:41:35,960
We are out of things that you can do.

505
00:41:36,150 --> 00:41:44,140
So if you do stay road, yeah, we are a number of things that we want to do, including including the

506
00:41:44,240 --> 00:41:47,180
fields that are on you are DOCTYPE.

507
00:41:47,720 --> 00:41:53,340
So if for instance, I wanted to do something with the other, I can do self-taught.

508
00:41:53,380 --> 00:41:55,010
All the other.

509
00:41:56,960 --> 00:42:02,030
Surfboat order, and I'll be able to get to do stuff with this function here.

510
00:42:02,930 --> 00:42:04,710
So today we want to check.

511
00:42:04,850 --> 00:42:07,480
We want to check on communities.

512
00:42:07,940 --> 00:42:13,850
We want to check what is the value of the safe dirt track by us?

513
00:42:14,330 --> 00:42:20,330
Truck by us is the name of the field that we created here.

514
00:42:21,870 --> 00:42:28,980
If if maybe for some reason you try to do this and if you is not found, just try to check from your

515
00:42:28,980 --> 00:42:37,260
customized make sure that the name of you field here, the name of your food here, remember, we be

516
00:42:37,260 --> 00:42:38,870
able to give a different name.

517
00:42:39,120 --> 00:42:40,740
We can call this truck by us.

518
00:42:41,620 --> 00:42:46,240
And we give this a different name, we give this a completely different name, so make sure that the

519
00:42:46,240 --> 00:42:49,870
name that you have here is what you are trying to access from your doctor.

520
00:42:50,770 --> 00:42:57,160
And then when you when we were treating this field, I made this thing in such a way that by default,

521
00:42:57,160 --> 00:43:04,720
if I edit it here by default, when we are when we are adding a new a new item, the buyer will come

522
00:43:04,720 --> 00:43:05,110
check.

523
00:43:05,230 --> 00:43:09,220
So it will come with a default value of one, but then you can uncheck it.

524
00:43:09,220 --> 00:43:12,850
And when you enter it, the value goes back to zero.

525
00:43:13,120 --> 00:43:21,490
So here what we have in our code is if self-destruct by us is zero, that means it is not checked.

526
00:43:22,030 --> 00:43:29,460
Then I'm giving another condition, like if if self-torture by us, of course, to by us.

527
00:43:29,470 --> 00:43:33,450
Now the buyer's here, remember is the name.

528
00:43:34,300 --> 00:43:36,820
Let's go down here, the name of the table.

529
00:43:37,090 --> 00:43:45,310
So what we are telling our code here is if the name he is the checkbox is not checked, then check number

530
00:43:45,310 --> 00:43:45,700
two.

531
00:43:45,700 --> 00:43:51,610
If our buyers object has anything self-torture by us means check whether this one has anything.

532
00:43:52,030 --> 00:44:00,970
And if yes, then the this message rapido through the through method does not allow floor to continue.

533
00:44:01,120 --> 00:44:06,800
If we do hear message print, if we just do message print here it is being a print message, but it

534
00:44:06,800 --> 00:44:10,420
to go ahead and allow us to see if we can see if we tested.

535
00:44:11,830 --> 00:44:18,420
Why we said our thing, if we come here, not here, let me go back.

536
00:44:18,450 --> 00:44:24,630
I think I heard it and I really remember what you may need to hurry this together thing, watching Andy

537
00:44:24,630 --> 00:44:26,770
for some reason, even after the control shift.

538
00:44:26,800 --> 00:44:27,930
Ah, it doesn't work.

539
00:44:27,930 --> 00:44:30,050
Try to restart yourself.

540
00:44:30,960 --> 00:44:34,850
So here we have two of these guys and this one is sick.

541
00:44:34,860 --> 00:44:40,290
So if I say this is going to change, what if I do something here and save?

542
00:44:40,590 --> 00:44:41,790
It allows me to save.

543
00:44:42,390 --> 00:44:44,030
And what if I am sick?

544
00:44:44,040 --> 00:44:48,290
I want you to see what is going to happen here is going to draw, not to draw.

545
00:44:48,300 --> 00:44:48,510
Yeah.

546
00:44:48,510 --> 00:44:52,670
Is going to put into a message, but then it is going to go ahead and save.

547
00:44:52,680 --> 00:44:57,870
So just take the message that we have here and also take the message that we have a notification that

548
00:44:57,870 --> 00:44:58,650
comes up here.

549
00:44:58,920 --> 00:45:01,620
So when I say it, the truth, I'm visiting me.

550
00:45:01,980 --> 00:45:08,220
This article does not strike by us by then if they are saved, because ideally what we have here is

551
00:45:08,220 --> 00:45:09,230
a message print.

552
00:45:09,480 --> 00:45:15,360
So when you do a message print, this does not interrupt the flow of of of the application.

553
00:45:15,690 --> 00:45:21,450
It prints the message for the user, but then it goes ahead and execute the next steps.

554
00:45:21,870 --> 00:45:27,540
But when we do through this little function stops.

555
00:45:27,540 --> 00:45:31,590
You are the control of the vehicle stops.

556
00:45:31,590 --> 00:45:36,200
You are the the next steps that follow from here.

557
00:45:36,210 --> 00:45:41,280
So if we do when we do this, this flow is not going to continue then the function.

558
00:45:41,320 --> 00:45:47,730
The moment this one is reached, our application is going to throw this message to the user and then

559
00:45:47,730 --> 00:45:50,180
it is going to stop there and wait for the next action.

560
00:45:50,610 --> 00:45:55,560
So when we see that, come back here to see if they are to reload.

561
00:45:57,680 --> 00:46:03,580
And we change something, let me first of all, take that so they just have something to change.

562
00:46:04,100 --> 00:46:05,170
This one I saved.

563
00:46:05,540 --> 00:46:08,010
But then remember, they are safe because you are tracking users.

564
00:46:08,240 --> 00:46:11,530
How about if I can check it and I try to save it?

565
00:46:11,540 --> 00:46:12,380
Just look at that.

566
00:46:12,770 --> 00:46:16,210
They been telling us this application does not track by us.

567
00:46:17,030 --> 00:46:20,360
So that means I need to remove this this tool.

568
00:46:20,510 --> 00:46:23,550
So I remove that and also remove that other you.

569
00:46:23,700 --> 00:46:24,980
I try to save it with this one.

570
00:46:24,980 --> 00:46:28,400
I inject save it and it is successful so that they are saved.

571
00:46:29,090 --> 00:46:33,860
If I come back here to try to add somebody else just to, to, to be sure.

572
00:46:35,180 --> 00:46:39,730
Giuffre and yeah we have that, we have the phone number here.

573
00:46:40,490 --> 00:46:42,930
I try to save with this one object.

574
00:46:42,980 --> 00:46:44,390
Save it.

575
00:46:44,400 --> 00:46:49,820
That does not allow me to save any, does not allow me to save any, any by ACM.

576
00:46:50,120 --> 00:46:50,990
So that's it.

577
00:46:51,290 --> 00:46:59,750
So this is the code we have written and this is what is used to control and interrupt flow in case we

578
00:46:59,750 --> 00:47:03,760
need to check the Felisha and manipulate other fields depending on them.

579
00:47:04,990 --> 00:47:07,880
I open the floor for any questions if you have.

580
00:47:21,760 --> 00:47:25,370
Any question that.

581
00:47:30,190 --> 00:47:40,870
OK, now now you did some code in the Python controller when you decided to put code in controller and

582
00:47:41,020 --> 00:47:44,690
code in JavaScript in Java, fire, just fire.

583
00:47:44,920 --> 00:47:48,340
So this one, you can do it in JavaScript, right?

584
00:47:50,170 --> 00:47:59,830
You can do it, you can do it in JavaScript, Mummy, but sometimes you may need to do things here that

585
00:48:00,160 --> 00:48:06,460
with this this input just before validate, you may need to do things that JavaScript can not do.

586
00:48:06,470 --> 00:48:10,780
And also remember that mummy JavaScript is up front.

587
00:48:10,780 --> 00:48:16,030
And in the case of Rabbit, in the case of JavaScript can also be used in the backend.

588
00:48:16,750 --> 00:48:22,000
But JavaScript in Frappé and ERP next is used for front end stuff.

589
00:48:22,450 --> 00:48:26,110
So JavaScript is used to control what happens here.

590
00:48:26,140 --> 00:48:28,230
What happens in this, would they use outside?

591
00:48:28,990 --> 00:48:32,330
But then Python is used for backend.

592
00:48:32,620 --> 00:48:38,770
So what happens in the backend after the user has submitted this data before the thing goes into the

593
00:48:38,770 --> 00:48:41,040
database, something needs to happen.

594
00:48:41,440 --> 00:48:48,490
Some things may need to happen and you may need to process some things inside Python not we will not

595
00:48:48,490 --> 00:48:49,390
do that in frappé.

596
00:48:49,390 --> 00:48:53,650
So you may need to write things inside of inside of.

597
00:48:53,650 --> 00:48:58,080
You are controllers in the in our Kizzia our controllers are in Python.

598
00:48:58,840 --> 00:48:59,860
So that is the difference.

599
00:49:00,880 --> 00:49:07,090
OK, you are saying the controller is stronger than the JavaScript.

600
00:49:09,040 --> 00:49:18,880
The more robust solution you put, if you put the validation or control in the controller, find no

601
00:49:18,880 --> 00:49:20,420
way to go to the database.

602
00:49:20,440 --> 00:49:23,450
Maybe you missed something in the front end.

603
00:49:24,100 --> 00:49:28,380
Just make up the same makeup in the front end.

604
00:49:28,390 --> 00:49:32,680
Some validation feels empty or it is not accepted.

605
00:49:32,680 --> 00:49:42,970
That controller, it will not pass the data to database unless it validate all conditions.

606
00:49:43,980 --> 00:49:45,830
Yes, correct, correct.

607
00:49:46,360 --> 00:49:54,780
The other point to note here is that every code that you write on the front end is accessible to front

608
00:49:54,780 --> 00:49:55,050
end.

609
00:49:55,530 --> 00:50:01,200
So people, even if they don't have access to it, especially Howcast, they can be able to manipulate

610
00:50:01,200 --> 00:50:07,530
code that is running on JavaScript files, but they are not able to manipulate code unless if if the

611
00:50:07,530 --> 00:50:12,750
endpoints are open, they are not able to manipulate code that is on the server on the server side of

612
00:50:12,750 --> 00:50:13,400
your application.

613
00:50:14,250 --> 00:50:15,930
So that's another big difference to note.

614
00:50:17,120 --> 00:50:23,090
It is the last time we did some got together to fetch the full name, you remember?

615
00:50:23,690 --> 00:50:24,590
Yes, yes.

616
00:50:26,690 --> 00:50:28,040
You have that right.

617
00:50:29,690 --> 00:50:30,590
Let me see.

618
00:50:30,710 --> 00:50:33,400
It caused all the obvious focus.

619
00:50:33,410 --> 00:50:34,730
I think I deleted it.

620
00:50:35,030 --> 00:50:43,400
What they have here is to calculate the total cost of the total cost of the total cost of a book or

621
00:50:43,400 --> 00:50:44,030
an article.

622
00:50:45,260 --> 00:50:48,020
OK, I can share my screen to show you a case.

623
00:50:48,380 --> 00:50:49,190
Please go ahead.

624
00:50:58,880 --> 00:50:59,720
You see on my screen.

625
00:51:02,200 --> 00:51:15,730
Yes, it's coming up, yes, now in my screen, if this filled full name is it is written by the court,

626
00:51:16,190 --> 00:51:18,540
it's open to called.

627
00:51:27,310 --> 00:51:30,730
There is a God you remember the full name is Fitchett from.

628
00:51:33,490 --> 00:51:35,920
From the control room, I'll show you.

629
00:51:39,240 --> 00:51:39,460
In.

630
00:51:52,570 --> 00:51:56,820
The time to remember this, this is the call.

631
00:51:57,870 --> 00:52:03,290
Yeah, OK, yeah, so here before saving, we are writing fullName.

632
00:52:03,600 --> 00:52:04,680
This is the full name.

633
00:52:04,680 --> 00:52:09,570
It's his first name concatenated with the last year years here.

634
00:52:09,570 --> 00:52:14,280
My first name, last name and the full name, OK.

635
00:52:15,030 --> 00:52:17,010
Normally it is empty like this.

636
00:52:17,460 --> 00:52:19,600
When you enter data it was empty.

637
00:52:19,950 --> 00:52:27,600
If I see you, if I say now I got the full name from the database once to refresh it, the record was

638
00:52:27,600 --> 00:52:28,050
inefficient.

639
00:52:28,130 --> 00:52:29,990
It is fitchett from database.

640
00:52:30,000 --> 00:52:30,280
Right?

641
00:52:31,590 --> 00:52:37,790
Go back to my dorm so I could work it to fit, right?

642
00:52:39,000 --> 00:52:39,420
Yes.

643
00:52:39,720 --> 00:52:43,590
So full name is populated by code.

644
00:52:45,890 --> 00:52:47,330
Correct, yes.

645
00:52:47,780 --> 00:52:55,430
Now, the experience now, which I did, I suppose I put to number two here in the fullname my right

646
00:52:55,430 --> 00:52:56,040
to hear.

647
00:52:56,630 --> 00:53:01,160
So the system says Frappier will not take my entry in the fullname.

648
00:53:01,610 --> 00:53:04,160
It's not taking my entry into full name.

649
00:53:04,430 --> 00:53:07,770
It is not taking my entry in the front end if I save.

650
00:53:09,410 --> 00:53:15,990
Again, it's running the Python code and derived from the code, not from.

651
00:53:17,440 --> 00:53:18,790
Yes, let me tell you why.

652
00:53:18,800 --> 00:53:20,420
Go back to good to your code.

653
00:53:22,040 --> 00:53:23,560
So what is happening here?

654
00:53:23,810 --> 00:53:27,530
You see, you have done that before, Steve, so that when before C..

655
00:53:27,980 --> 00:53:34,350
So before you are code is saved, your application is taking the first name, whatever is in the first

656
00:53:34,370 --> 00:53:37,970
name field and whatever is in the second, the last name field.

657
00:53:38,150 --> 00:53:43,460
And then it is putting them together and then it is putting that result in their full name field.

658
00:53:44,000 --> 00:53:47,610
So that happens and then it goes ahead and saves.

659
00:53:48,290 --> 00:53:48,840
Yes.

660
00:53:49,310 --> 00:53:54,590
So your application, that is where you will not get even if you put something in the full name field,

661
00:53:54,830 --> 00:53:58,680
it will be overridden by this because it is happening before you see.

662
00:54:00,540 --> 00:54:05,630
Yes, yes, it's ignoring it is ignoring this one and ignoring.

663
00:54:07,410 --> 00:54:14,040
Because it's this cold is more high priority to be executed.

664
00:54:14,910 --> 00:54:16,390
Yes, yes, yes.

665
00:54:16,530 --> 00:54:22,980
So if, for instance, you misspelled your name, if your name is Mummie four, five, six, your second

666
00:54:22,980 --> 00:54:26,230
name, you need to change that in your last name.

667
00:54:26,760 --> 00:54:29,310
So if you do they for five, six, it is going to accept.

668
00:54:34,420 --> 00:54:35,020
Yes.

669
00:54:37,300 --> 00:54:44,650
Actually, this is what my observation that if even you write something in the front end, the God,

670
00:54:44,650 --> 00:54:49,520
it's all right, it's ignoring it is ignore it.

671
00:54:49,670 --> 00:54:51,400
Whatever you enter here, it's ignored.

672
00:54:51,850 --> 00:54:53,410
So the python code is working.

673
00:54:53,410 --> 00:54:58,990
Once it's working, it is overriding whatever interest in the front end is.

674
00:54:58,990 --> 00:54:59,480
Correct.

675
00:54:59,830 --> 00:55:05,200
That's why they put, for example, if you in this case, you put it as Read-Only.

676
00:55:07,070 --> 00:55:08,350
Yes, he is correct.

677
00:55:08,430 --> 00:55:09,050
Yeah, yeah.

678
00:55:11,190 --> 00:55:12,600
So that's it.

679
00:55:12,840 --> 00:55:13,530
Thank you.

680
00:55:14,280 --> 00:55:17,640
So let's get a question from the team.

681
00:55:20,570 --> 00:55:29,240
So now today he's trying to explain the controller file, what he doing exactly, so he put some logic

682
00:55:29,240 --> 00:55:32,670
in the controller file to validate the timetable.

683
00:55:32,900 --> 00:55:35,360
We saw also tried to get created.

684
00:55:35,360 --> 00:55:40,100
The link is between the parent and the child.

685
00:55:41,330 --> 00:55:50,120
Parent record and child record was designed to do so.

686
00:55:50,120 --> 00:56:02,350
Let us know, is it clear this topic like this we have we took this is our first topic from the advanced

687
00:56:02,630 --> 00:56:07,700
that's working with controllers or industrial entropic framework.

688
00:56:08,060 --> 00:56:16,880
So it's clear we didn't see a screen and we will see maybe another test cases coming.

689
00:56:17,110 --> 00:56:19,940
Decisions maybe, or.

690
00:56:23,120 --> 00:56:23,710
OK.

691
00:56:25,220 --> 00:56:27,090
Mummy, Mummy, you think you didn't see a out?

692
00:56:27,820 --> 00:56:33,510
Oh, no, I mean, today we didn't just a squirrel, a squirrel.

693
00:56:35,540 --> 00:56:36,260
So the topic.

694
00:56:36,530 --> 00:56:41,620
Yeah, the topic is working with controllers Aughrim and Asprin.

695
00:56:42,440 --> 00:56:42,770
Yeah.

696
00:56:42,770 --> 00:56:48,740
Ask you and ask you is what we have been doing like when we are when you are getting the when you are

697
00:56:48,740 --> 00:56:51,740
getting the description of the tipoffs.

698
00:56:53,150 --> 00:56:55,840
Oh, yeah, let me say this.

699
00:56:56,060 --> 00:57:01,100
Remember, I ask you, it is very, very broad, so we cannot cover everything.

700
00:57:01,790 --> 00:57:02,720
Can you see my screen?

701
00:57:03,360 --> 00:57:04,000
Yes, yes.

702
00:57:04,310 --> 00:57:06,290
So this is one example of Estherville.

703
00:57:06,310 --> 00:57:07,400
We are getting this.

704
00:57:07,820 --> 00:57:12,580
You may also be able to get like what you are doing here, selecting him from this.

705
00:57:12,800 --> 00:57:15,920
So this is raw as you are, right?

706
00:57:16,110 --> 00:57:19,010
It's it's a it's a large, large ludger.

707
00:57:19,190 --> 00:57:23,180
There's a lot of content to learn from Estherville.

708
00:57:23,450 --> 00:57:29,060
So what we did here is just the commands that you can use maybe to get the description of a table where

709
00:57:29,060 --> 00:57:32,990
you don't have access to my admin or whatever you're using to manage.

710
00:57:33,410 --> 00:57:35,990
You are Easton's virtual reality.

711
00:57:37,130 --> 00:57:40,640
That is that is what I meant by you out here.

712
00:57:41,120 --> 00:57:50,420
You know, my my expectation actually when I read this topic, it's like we did last time and we have

713
00:57:50,420 --> 00:57:51,630
created an API.

714
00:57:51,630 --> 00:58:01,180
You remember, you create an API and you execute DB for capital to be is good right now.

715
00:58:01,230 --> 00:58:01,490
Yeah.

716
00:58:01,520 --> 00:58:08,510
OK, ok, so this is the scroll inside the it's one database API.

717
00:58:09,380 --> 00:58:09,860
Yes.

718
00:58:11,630 --> 00:58:16,130
This part I think we will see it in other tests.

719
00:58:17,420 --> 00:58:17,780
Yeah.

720
00:58:18,220 --> 00:58:18,590
Yeah.

721
00:58:18,800 --> 00:58:22,220
We are going to be, we are going to be working on them as we move along.

722
00:58:23,540 --> 00:58:28,230
But my disclaimer is we can't cover everything enescu ill.

723
00:58:28,520 --> 00:58:34,790
So if, if maybe for some, maybe people I not explored this will I would strongly advise that they

724
00:58:34,790 --> 00:58:36,680
look at courses on Askia.

725
00:58:36,700 --> 00:58:37,790
It's really broad.

726
00:58:38,690 --> 00:58:39,230
No, no.

727
00:58:39,230 --> 00:58:45,980
My point garani again and your controller you can write this could write to fetch data.

728
00:58:46,700 --> 00:58:48,730
It's not only get data, get the.

729
00:58:51,470 --> 00:58:54,350
Yeah, I mean, you can write this, we have done it before, right?

730
00:58:54,620 --> 00:58:56,870
Yes, yes, this is the point.

731
00:58:56,990 --> 00:58:59,430
Yeah, yeah, yeah.

732
00:58:59,480 --> 00:59:00,350
This is the point.

733
00:59:00,350 --> 00:59:04,510
And the controller, you can fetch data using Istria.

734
00:59:05,580 --> 00:59:06,080
Hmm.

735
00:59:06,860 --> 00:59:07,640
You got a name.

736
00:59:07,650 --> 00:59:10,030
So we have to include a school in the country.

737
00:59:10,180 --> 00:59:13,910
Oh, yes, yes, yes, yes, yes.

738
00:59:14,300 --> 00:59:15,120
This is the point.

739
00:59:15,470 --> 00:59:20,480
So this is what means in the topic at this point.

740
00:59:21,580 --> 00:59:21,740
Right.

741
00:59:22,240 --> 00:59:22,640
OK.

742
00:59:23,960 --> 00:59:25,760
So we saw some cases already.

743
00:59:25,760 --> 00:59:35,560
We cover this in previous topics in the beginning so we can explore more cases coming and decisions.

744
00:59:36,490 --> 00:59:37,120
Sure, sure.

745
00:59:37,130 --> 00:59:37,360
Sure.

746
00:59:38,270 --> 00:59:43,340
Only this is the only option, I think, to include the school and the controller.

747
00:59:43,750 --> 00:59:46,150
This one this the debate of the school.

748
00:59:46,190 --> 00:59:46,520
Right.

749
00:59:46,730 --> 00:59:47,860
Not the others.

750
00:59:48,110 --> 00:59:48,680
The others.

751
00:59:49,070 --> 00:59:49,320
Mm.

752
00:59:49,850 --> 00:59:50,210
Yeah.

753
00:59:50,210 --> 00:59:51,350
We can get through that later.

754
00:59:52,190 --> 00:59:52,580
OK.

755
00:59:53,150 --> 00:59:57,460
And also if, if maybe someone has a specific question they can drop it to you.

756
00:59:57,540 --> 00:59:59,750
You can look at it is.

757
01:00:02,150 --> 01:00:03,010
OK, fine.

758
01:00:05,710 --> 01:00:12,000
So I hope it is covering the topic.

759
01:00:13,370 --> 01:00:16,250
So regarding controller.

760
01:00:18,750 --> 01:00:21,740
So if there is no question, we shall close the call.

761
01:00:23,370 --> 01:00:23,850
Is.

762
01:00:25,930 --> 01:00:32,920
Just one question, yeah, yeah, Karen, could you open your visual studio code and the code which

763
01:00:32,920 --> 01:00:34,050
you have written just now?

764
01:00:37,470 --> 01:00:37,890
Hello.

765
01:00:42,820 --> 01:00:45,790
I do, yeah, you see my screen.

766
01:00:48,130 --> 01:00:50,850
Yes, I can see a screen, OK?

767
01:00:51,070 --> 01:00:52,290
Could I have highlighted the.

768
01:00:53,310 --> 01:00:55,870
So you have written one more function before

769
01:01:00,610 --> 01:01:04,200
this function, before revalidate, after that function.

770
01:01:04,230 --> 01:01:06,540
You have written Wendler function before safe.

771
01:01:07,450 --> 01:01:14,260
Yes, yeah, yeah, so what about this thing, is this being used or anything like this, this one?

772
01:01:14,600 --> 01:01:17,190
Yeah, no, we did this earlier.

773
01:01:17,240 --> 01:01:18,660
This is something we did earlier.

774
01:01:18,670 --> 01:01:24,500
So it's not it's not useful for what we have done today or this is something we did on on our previous

775
01:01:24,500 --> 01:01:24,970
session.

776
01:01:25,000 --> 01:01:25,390
Yes.

777
01:01:25,420 --> 01:01:26,020
Yeah, yeah, yeah.

778
01:01:26,650 --> 01:01:28,120
That said yesterday.

779
01:01:28,120 --> 01:01:28,380
Right.

780
01:01:28,620 --> 01:01:28,930
Yes.

781
01:01:29,900 --> 01:01:33,800
Was it is today, I think it was a couple of days ago.

782
01:01:33,830 --> 01:01:34,800
It was not yesterday.

783
01:01:35,150 --> 01:01:35,940
It was working with.

784
01:01:36,680 --> 01:01:41,090
So when was that working with emails?

785
01:01:41,110 --> 01:01:49,390
It was about emails two days earlier in the day, in day nine.

786
01:01:49,390 --> 01:01:52,900
And then it was indeed correct.

787
01:01:53,180 --> 01:01:53,630
Yes.

788
01:01:55,720 --> 01:01:57,170
Do it soon.

789
01:01:58,230 --> 01:02:05,630
So basically the code gets executed when the relevant fields access to data and then that is accessed,

790
01:02:05,650 --> 01:02:08,080
the court will just as it is.

791
01:02:09,430 --> 01:02:10,000
Yes.

792
01:02:11,740 --> 01:02:14,920
Which which field, which field in which field.

793
01:02:17,410 --> 01:02:21,370
So the email came in code, which Garani had written.

794
01:02:21,970 --> 01:02:24,840
So since we haven't used that email part here.

795
01:02:25,120 --> 01:02:27,730
So that's why that code did not yet executed at midnight.

796
01:02:28,840 --> 01:02:36,280
No, if they execute that, actually, if we don't comment everything really just the movies you see

797
01:02:36,280 --> 01:02:38,410
here, we have a message print at the bottom.

798
01:02:38,420 --> 01:02:40,360
You're seeing articles, even animals, Cynthia.

799
01:02:41,800 --> 01:02:48,770
So if this goes on successfully, if the valeted function is successful, we are expecting to see Assif

800
01:02:48,800 --> 01:02:54,040
message on the bottom side of our screen and also see a message print, because this this function will

801
01:02:54,040 --> 01:02:56,340
be reached also and it will do its thing.

802
01:02:56,770 --> 01:02:59,140
But if this one fails, we are not going to see this.

803
01:02:59,560 --> 01:03:06,310
Let me show you that I go to my front end and here this one is not checked.

804
01:03:06,400 --> 01:03:08,930
So we are not expecting to see anyone here.

805
01:03:09,340 --> 01:03:12,970
I don't think this yeah, this article does not track by us.

806
01:03:13,130 --> 01:03:17,500
OK, so we are only one minutes now.

807
01:03:18,490 --> 01:03:22,510
How about so that means this this is what was printed.

808
01:03:22,510 --> 01:03:25,840
These are through here and therefore this function was not reached.

809
01:03:26,410 --> 01:03:32,470
Now how about we check this one invaded that failed because we have this, this, this, this.

810
01:03:32,470 --> 01:03:39,640
Biagio, if we check this and allow the doctor to track by us and to see if we are seeing a message

811
01:03:39,640 --> 01:03:43,270
print article saved, an e-mail sent that one is coming from here.

812
01:03:44,260 --> 01:03:45,360
So this one reads.

813
01:03:47,610 --> 01:03:54,390
For instance, if, for instance, we will change this message print in this case, because the message

814
01:03:54,390 --> 01:03:59,910
print does not stop the execution of these other functions, we are expecting to see a misprint.

815
01:03:59,910 --> 01:04:05,890
One seeing this article does not track by us and by then this will go ahead and also save it.

816
01:04:06,240 --> 01:04:11,520
So we are expecting to see also this this other other message is go ahead and try it out.

817
01:04:12,680 --> 01:04:15,860
So we can leave this one sect it.

818
01:04:17,030 --> 01:04:19,010
You see this one, we have two messages.

819
01:04:20,890 --> 01:04:29,890
So we have to drop and also the other one thing, the other message, so if the execution continues,

820
01:04:29,890 --> 01:04:32,680
if there is the validity, function is successful.

821
01:04:37,310 --> 01:04:37,790
Thank you.

822
01:04:39,780 --> 01:04:44,860
Overall, Garani, there is a throw error message.

823
01:04:45,630 --> 01:04:53,100
The code is get stopped, whatever this will happen and this will not continue the the rest of the code,

824
01:04:53,100 --> 01:04:53,430
right?

825
01:04:53,790 --> 01:04:54,540
Absolutely.

826
01:04:55,200 --> 01:04:56,010
It will exit.

827
01:04:56,460 --> 01:04:57,060
Absolutely.

828
01:04:57,060 --> 01:04:57,360
Yes.

829
01:04:58,350 --> 01:05:03,170
It will not take next admitted or next function.

830
01:05:03,780 --> 01:05:04,530
It will not.

831
01:05:05,340 --> 01:05:12,120
Even if we hit something here like below here we had some other code that was running here and whatever,

832
01:05:12,120 --> 01:05:12,870
whatever, whatever.

833
01:05:13,170 --> 01:05:20,590
And then this thing is if response returns through and the execution comes here, these are the code

834
01:05:20,640 --> 01:05:26,760
will not be executed, even if it is in the same function they control will be stopped at this point.

835
01:05:28,480 --> 01:05:29,920
OK, yeah.

836
01:05:30,750 --> 01:05:31,120
Uh.

837
01:05:35,800 --> 01:05:36,120
Great.

838
01:05:36,940 --> 01:05:39,250
OK, any other question is.

839
01:05:44,940 --> 01:05:45,430
OK.

840
01:05:48,930 --> 01:05:53,010
So if there is no question, we shall close the call.

841
01:05:55,060 --> 01:05:57,680
And so, Bernard, you can stay with us.

842
01:05:57,690 --> 01:06:01,140
