00:00:00,600 --> 00:00:02,330
Hello and welcome in this chair.

2
00:00:02,340 --> 00:00:07,080
We are going to try and see that are in B control.

3
00:00:07,410 --> 00:00:17,310
In a previous Lakeshore we created a model so we're going to do how it is meant to create action to

4
00:00:17,310 --> 00:00:20,760
reflect the new model that was created.

5
00:00:21,120 --> 00:00:30,260
So make sure you are him the post on this call control file and you can see this is the create action.

6
00:00:30,270 --> 00:00:36,690
We just need to our members since we've created a model at the moment what is doing is just rendering

7
00:00:36,690 --> 00:00:43,360
whether it's posted on the form is meant the net rendering it as an object like this.

8
00:00:43,380 --> 00:00:47,530
So we want it to render to the database via that model.

9
00:00:47,550 --> 00:00:49,860
So I'm just going to comment that out.

10
00:00:49,860 --> 00:00:54,010
You can delete it if you wish to do so but come in today for now.

11
00:00:54,240 --> 00:00:55,730
We just had some.

12
00:00:55,740 --> 00:00:59,280
I'm going to start by adding it variable and variable.

13
00:00:59,280 --> 00:01:02,880
I'm going to add I'm going to call it pause.

14
00:01:03,240 --> 00:01:07,410
So this is the same board to had variable in Ruby.

15
00:01:07,410 --> 00:01:12,000
So you just look at full of by paused in law case.

16
00:01:12,270 --> 00:01:21,550
I'm going to set that to equal to OP Keith Post dot new.

17
00:01:23,490 --> 00:01:24,750
N n t.

18
00:01:24,770 --> 00:01:38,990
Parent disease inside the person who sees half passing nipa trumps an ad and every column and then passing

19
00:01:39,080 --> 00:01:42,440
the post object.

20
00:01:45,100 --> 00:01:47,210
So what I've done here.

21
00:01:47,350 --> 00:01:57,170
That line of code basically any time you create a model you have to initialize the model you uninitialised.

22
00:01:57,190 --> 00:01:59,570
You've seen its attributes.

23
00:01:59,830 --> 00:02:08,740
So here be the attributes here are automatically mapped to the respective database columns so these

24
00:02:08,740 --> 00:02:20,620
two columns in a database which is title and the body and we represent in that we're the paramus and

25
00:02:20,620 --> 00:02:27,720
then the post that will give us the values of the columns in the database table.

26
00:02:28,330 --> 00:02:37,450
Another thing we can do is add on another variable that will be responsible for saving the module in

27
00:02:37,450 --> 00:02:38,820
the database.

28
00:02:39,040 --> 00:02:41,090
So we're just going to add that variable now.

29
00:02:41,130 --> 00:02:50,110
So we do at the time pick the word Post dot see.

30
00:02:51,160 --> 00:03:00,160
So this is what will save the data into the database using the model and then once it's been safe you

31
00:03:00,160 --> 00:03:05,140
want to be able to redirect it back somewhere so you do redirect

32
00:03:07,840 --> 00:03:20,770
on the score to 1 to redirect it back to the post variable at ports.

33
00:03:22,460 --> 00:03:25,350
I just want to create a space between that with the one hole.

34
00:03:25,480 --> 00:03:25,950
Okay.

35
00:03:26,120 --> 00:03:31,360
So read did underscore to at this post variable.

36
00:03:31,780 --> 00:03:39,510
So this read death rate here is going to redirect the user to the show action.

37
00:03:39,610 --> 00:03:45,550
We've not defined the show action yet but that's where it will redirect the user to something I want

38
00:03:45,550 --> 00:03:46,510
to point out here.

39
00:03:46,540 --> 00:03:51,940
Notice here we set this up pause variable two equals to pause new.

40
00:03:52,090 --> 00:04:02,440
And the reason we've got the P in upper case everything is capitalize is that it is referred to as a

41
00:04:02,470 --> 00:04:03,100
class.

42
00:04:03,100 --> 00:04:04,060
It is a class.

43
00:04:04,060 --> 00:04:07,290
That's why it is capitalized.

44
00:04:07,510 --> 00:04:18,680
So we are actually referring to V post that defined n bit cap models article Dort are B.

45
00:04:18,860 --> 00:04:19,350
All right.

46
00:04:19,360 --> 00:04:26,240
So we could post on this yeah to the HARP on the score models.

47
00:04:26,260 --> 00:04:34,570
If you go to aps and then go to modules and post B were referring to this class.

48
00:04:34,570 --> 00:04:42,790
This is a class where a to you can seise upper case P here so that's why we've got the upper case here.

49
00:04:42,820 --> 00:04:48,490
Thus the fear of the post it is referring to.

50
00:04:48,490 --> 00:04:54,110
So let's see and try and submit our form and see what happens.

51
00:04:54,280 --> 00:05:00,380
So we refresh this week in gowe form back.

52
00:05:01,900 --> 00:05:02,850
So this is our form.

53
00:05:02,860 --> 00:05:08,910
So let me just try and post something and I do expect to get an error.

54
00:05:09,550 --> 00:05:13,290
Click save and see what happens.

55
00:05:13,690 --> 00:05:16,660
So you can see we are getting an error here.

56
00:05:16,660 --> 00:05:18,240
Let me just expand the Thera.

57
00:05:18,550 --> 00:05:23,260
So is saying active model for the entire trip is the reason we're getting this error is that we've not

58
00:05:23,660 --> 00:05:31,320
had fully defined any special fields full of post so we don't live in peoples minds.

59
00:05:31,330 --> 00:05:36,130
We must define the feel we dont want people to just post anything they like.

60
00:05:36,160 --> 00:05:45,640
So if the security issues that we need to address so Real's has several security features that helps

61
00:05:45,640 --> 00:05:53,260
you right seek your application so when you are run into one of those features like we can see here

62
00:05:53,260 --> 00:05:59,480
on the screen may actually called strong prime it is what that does it out to be.

63
00:05:59,500 --> 00:06:09,600
He requires all reals is telling us to tell it exactly what parameters we are going to allow in to harm

64
00:06:09,610 --> 00:06:18,490
a controller actions so we need to tell it what we have to do is create a private method or action that

65
00:06:18,490 --> 00:06:27,310
can only be accessed from this class so when a method is made private It cannot be accessed outside

66
00:06:27,520 --> 00:06:31,000
the class so you need to create a private metal.

67
00:06:31,020 --> 00:06:35,460
You type in the word private.

68
00:06:35,600 --> 00:06:43,020
Okay and then here then you then define do a diff to define.

69
00:06:43,540 --> 00:06:49,680
Then I'm going to call it post on the score.

70
00:06:49,690 --> 00:06:53,200
Programs or the parameters.

71
00:06:53,530 --> 00:07:03,530
And here I'm going to specifying some values and when I say firearms do not require so I am setting

72
00:07:03,550 --> 00:07:19,720
the feels that the form will require and then empathises is on typing post and then here do not permit

73
00:07:20,620 --> 00:07:26,960
which means these other fields are permitted or fields or columns permitted.

74
00:07:27,280 --> 00:07:44,710
And then you do a call on the title we want the title comma space and there we also want the body so

75
00:07:44,770 --> 00:07:47,740
to call on unban.

76
00:07:48,370 --> 00:07:48,930
But the.

77
00:07:50,560 --> 00:07:55,410
And we need to end the methot typing end as to end it.

78
00:07:55,640 --> 00:08:04,340
So now that we've defined the we defined it created this private method here and we've got this action

79
00:08:04,340 --> 00:08:15,680
here called programs we have to amend the variable here to reflect what we have set here and the way

80
00:08:15,680 --> 00:08:22,070
we do that where we've got Post he to pause and cool down new.

81
00:08:22,380 --> 00:08:23,740
So we're going to keep passing.

82
00:08:23,780 --> 00:08:28,650
We're going to change this because we've got we're going to get the value from here.

83
00:08:28,790 --> 00:08:35,810
So we changed that from paramus Depp to post

84
00:08:38,480 --> 00:08:41,030
on the score.

85
00:08:41,580 --> 00:08:43,060
Paramount's

86
00:08:45,880 --> 00:08:53,460
okay because we've already defined it here so we're picking the values from here and amended it there.

87
00:08:54,410 --> 00:09:03,410
So now if we save and then go back and refresh half form or fully that we should now be able to save

88
00:09:03,860 --> 00:09:06,380
data to the controller.

89
00:09:07,250 --> 00:09:14,710
So led to a test and got to turn to code test and anybody else has called a textureless to save post.

90
00:09:14,840 --> 00:09:18,640
Hopefully we should not get the error.

91
00:09:20,040 --> 00:09:23,660
Actually yes we have gotten there and it's a valid error.

92
00:09:23,680 --> 00:09:27,250
The reason we have got the error is is clearly obvious.

93
00:09:27,680 --> 00:09:35,700
We have not created the shule action inside the post quantrill So this is a post controller.

94
00:09:35,840 --> 00:09:38,050
He can see there's no issue here even.

95
00:09:38,170 --> 00:09:45,590
We got his save here we've told it to read there it took pause which is this show we haven't defined

96
00:09:45,590 --> 00:09:46,350
this show here.

97
00:09:46,370 --> 00:09:52,910
That's why we get in error so I'm going to end this lecture here in the next lecture.

98
00:09:52,910 --> 00:09:58,830
Will had the Schul action to the post controller.

99
00:09:59,090 --> 00:10:01,020
Many thanks for watching by.
