1 00:00:01,400 --> 00:00:02,570 In this section. 2 00:00:02,570 --> 00:00:06,260 We are going to work on the comments API. 3 00:00:06,290 --> 00:00:12,530 So let's get into the controllers and command and here we go for comments. 4 00:00:12,530 --> 00:00:14,000 You're going to have a couple of steps. 5 00:00:14,030 --> 00:00:19,850 Remember, first is you want to find the post that we want to add the comment to. 6 00:00:19,850 --> 00:00:26,090 And after that we are going to push the comment credit into the user's comment field. 7 00:00:26,090 --> 00:00:32,420 And for this one, it's an optional If you want to have all the comments that a user has created, then 8 00:00:32,420 --> 00:00:35,720 you can push the comment into the user's field. 9 00:00:35,720 --> 00:00:40,640 So first step is that we need to protect the controller or the root. 10 00:00:40,640 --> 00:00:45,680 So let's get into the root and comment root, which is this. 11 00:00:45,680 --> 00:00:48,500 So let's require the protected. 12 00:00:53,300 --> 00:00:53,990 All right. 13 00:00:53,990 --> 00:00:59,120 So let's pass it as a second argument to this, as protected. 14 00:00:59,480 --> 00:01:03,560 So let's get into the comments and let's have the roadmap. 15 00:01:03,830 --> 00:01:11,510 First step is less the structure, what the user is sending to the server as red dot body. 16 00:01:11,720 --> 00:01:19,700 For comment, we need let's have a look at the comment model, which is this We need the user and then 17 00:01:19,700 --> 00:01:22,550 the message the user is trying to create. 18 00:01:22,550 --> 00:01:28,010 So here is supposed to be message inside here. 19 00:01:28,160 --> 00:01:37,520 So inside the try first is let's find the post, So let's bring in the post model and then the user 20 00:01:37,520 --> 00:01:38,230 model. 21 00:01:38,240 --> 00:01:42,550 So let's save to have the go to import. 22 00:01:42,560 --> 00:01:54,770 So here I'm going to be the post model and then the user let me also receive it and going to be user. 23 00:01:54,770 --> 00:01:58,040 And I have the two models. 24 00:01:58,190 --> 00:02:10,490 So find the post is going to be caused post is equal to await post dart fine by ID and we can have the 25 00:02:10,490 --> 00:02:14,960 id on the rec dot params dot ID. 26 00:02:15,080 --> 00:02:17,150 Now this one is done. 27 00:02:17,180 --> 00:02:24,020 The next step is create the comment and it goes like this cost. 28 00:02:25,040 --> 00:02:34,160 The comment is equal to await the comment model less in the comment model also. 29 00:02:34,190 --> 00:02:35,450 Sorry guys. 30 00:02:35,450 --> 00:02:36,830 So here we go. 31 00:02:36,860 --> 00:02:39,020 The comment model. 32 00:02:40,500 --> 00:02:41,400 Perfect. 33 00:02:42,660 --> 00:02:43,140 All right. 34 00:02:43,140 --> 00:02:46,860 So comment and then dot create. 35 00:02:47,310 --> 00:02:50,820 Then you pass in the things that we want to create. 36 00:02:50,940 --> 00:02:58,350 First one going to be the user who is creating this comment and it can be found under rec the session. 37 00:03:00,890 --> 00:03:05,630 Don't user off then the message. 38 00:03:05,990 --> 00:03:07,490 And that is it. 39 00:03:07,520 --> 00:03:12,320 So after creating, then you push to the post. 40 00:03:12,320 --> 00:03:20,810 So I'm going to be as this remember, we have the post here, so it's going to be as post dot comments 41 00:03:20,810 --> 00:03:28,910 and dot push and we are pushing the ID of the comment going to be as comments dot underscore ID. 42 00:03:29,630 --> 00:03:35,900 The next step is that I want to push the common credit into the array of the users comments. 43 00:03:35,900 --> 00:03:40,280 So if you look at the users model, we have a field called comments. 44 00:03:40,280 --> 00:03:43,550 So in here we need to find the user. 45 00:03:46,350 --> 00:03:59,610 And going to be as cost user is equal to a weight user model defined by ID and we have the ID inside 46 00:03:59,610 --> 00:04:02,670 rec dot session dot user of. 47 00:04:03,840 --> 00:04:09,560 And let's push the comment into user. 48 00:04:09,570 --> 00:04:18,209 So you're going to be as a user comment dot push and I'm going to push the comment as that going to 49 00:04:18,209 --> 00:04:21,420 be as comment dot underscore ID. 50 00:04:21,810 --> 00:04:30,870 So last step is we need to the last step is we need to receive the post and then the user. 51 00:04:31,170 --> 00:04:35,730 And for this, let's go ahead and disable the validation. 52 00:04:35,730 --> 00:04:44,100 Otherwise mongoose, we say that we are trying to create a post by for post title is required or description 53 00:04:44,100 --> 00:04:44,970 is required. 54 00:04:44,970 --> 00:04:50,490 So let's disable the one and going to be as disable validation. 55 00:04:52,270 --> 00:05:00,130 And let's save the two models and going to be as I wait and the post. 56 00:05:01,250 --> 00:05:10,740 Don't save and you pass in an object and provide validation before save and force. 57 00:05:11,300 --> 00:05:17,690 And let's copy this one for the user as well, when it be as user. 58 00:05:18,230 --> 00:05:19,790 And that is it. 59 00:05:19,820 --> 00:05:23,330 Lastly, let's send back the comment. 60 00:05:24,080 --> 00:05:28,180 Let's go ahead and make the request to create a command. 61 00:05:28,190 --> 00:05:34,280 So let's get into the tender client and let's look at the comments, which is this. 62 00:05:34,550 --> 00:05:38,540 So for comments, we need to provide the ID of the post. 63 00:05:38,540 --> 00:05:43,790 So we're going to be asked API version one for this last comment. 64 00:05:45,570 --> 00:05:48,300 And let's have the ID of the post. 65 00:05:48,300 --> 00:05:52,320 So let's get back to all posts and hit send. 66 00:05:52,770 --> 00:06:00,510 I want to add comment to this post called CSS, so I'll copy this ID and here I'll provide the ID for 67 00:06:00,510 --> 00:06:01,050 that. 68 00:06:01,410 --> 00:06:08,880 So let me hit send and let's have a look where we got four or four, meaning that this root is not found. 69 00:06:09,000 --> 00:06:17,580 So let's get back to the comment route and let's see which is this well, supposed to be column ID for 70 00:06:17,580 --> 00:06:19,710 the great and that is it. 71 00:06:19,710 --> 00:06:22,230 So let's go ahead and make the request. 72 00:06:22,260 --> 00:06:24,510 Well, we still have the same error. 73 00:06:24,570 --> 00:06:30,350 The problem is we need to remove this a slash to have only one for slash. 74 00:06:30,360 --> 00:06:31,920 So let's hit send. 75 00:06:32,960 --> 00:06:37,550 You can see we have this error, meaning that we are not passing in the data. 76 00:06:37,550 --> 00:06:42,230 So here to create a command, we need to pass in the message. 77 00:06:44,490 --> 00:06:46,720 And I'll call this one as good. 78 00:06:46,740 --> 00:06:48,150 So let's hit send. 79 00:06:49,620 --> 00:06:52,740 And we have it as that is supposed to be. 80 00:06:52,740 --> 00:06:53,180 Good. 81 00:06:53,190 --> 00:06:58,080 So let me change this one to good and all right. 82 00:06:58,080 --> 00:07:00,810 So now we have the comments being created. 83 00:07:00,810 --> 00:07:08,940 So let's get back to our post and let's fetch our post and let's look at the post for CSS, which is 84 00:07:08,940 --> 00:07:09,210 this. 85 00:07:09,210 --> 00:07:12,660 And now we have to comment being added. 86 00:07:12,750 --> 00:07:19,530 And if I go to my profile page, I'll be able to see the comments that I have created. 87 00:07:19,530 --> 00:07:28,530 So if I go to users and then the profile, let's hit send and let's have a look on the comment. 88 00:07:28,950 --> 00:07:31,950 You can see I have created to comment. 89 00:07:31,950 --> 00:07:37,860 So let's see how we can populate the comment upon fetching all posts in the next video.
