1 00:00:01,130 --> 00:00:05,930 In this section, we are going to work on the post API. 2 00:00:06,080 --> 00:00:13,880 The most difficult part of the entire application is complete and that is the user API as compared to 3 00:00:13,880 --> 00:00:15,680 post and comment. 4 00:00:15,680 --> 00:00:21,710 So in this video we are going to create a controller to be able to create a post. 5 00:00:21,710 --> 00:00:28,100 So let's get back to the controllers and post controller before we can create a post. 6 00:00:28,100 --> 00:00:30,230 We need two modules. 7 00:00:30,230 --> 00:00:38,990 First one is the post itself and then the user module because we want to assist with a user to a post. 8 00:00:38,990 --> 00:00:41,060 So let me receive this file. 9 00:00:41,060 --> 00:00:48,230 Likewise, the user module also and let me get back to the post controller and let me require those 10 00:00:48,230 --> 00:00:49,520 two modules. 11 00:00:49,520 --> 00:00:54,050 The first one is a user and then the other one is post. 12 00:00:57,030 --> 00:00:57,910 Next ace. 13 00:00:57,960 --> 00:01:00,120 Let's look at the failures of the posts. 14 00:01:00,120 --> 00:01:03,540 So if you get back to the post model, we need the title. 15 00:01:03,540 --> 00:01:05,310 So let me place it here. 16 00:01:07,910 --> 00:01:11,750 And let me distract from the request body. 17 00:01:11,780 --> 00:01:17,900 So it's going to be as cost equal to rec dot body. 18 00:01:19,420 --> 00:01:22,030 We need the title of the post. 19 00:01:22,660 --> 00:01:25,000 Then the description. 20 00:01:26,370 --> 00:01:28,260 Then the category. 21 00:01:31,350 --> 00:01:33,030 Then the image. 22 00:01:36,150 --> 00:01:38,340 And then the user. 23 00:01:39,390 --> 00:01:39,960 Oh, right. 24 00:01:39,960 --> 00:01:41,820 So let me collapse this one. 25 00:01:42,000 --> 00:01:45,240 So first of all, let's look at the step. 26 00:01:45,450 --> 00:01:49,620 Step number one is we want to find the user. 27 00:01:49,650 --> 00:01:53,280 So inside the trial, our other comment here. 28 00:01:53,550 --> 00:01:56,280 So how can we get the user? 29 00:01:56,430 --> 00:02:01,560 Because of that, we need to put this controller behind authentication. 30 00:02:01,710 --> 00:02:07,380 So let's get back to the post route, which is this one. 31 00:02:07,380 --> 00:02:15,780 And here we are going to require the middleware to check if a user is logged in, which is called protected. 32 00:02:16,050 --> 00:02:26,790 So inside the post route, let me require the file as protected unless I do it manually as const protected 33 00:02:27,240 --> 00:02:35,400 is equal to ..4..4 slash and inside metaverse and protected. 34 00:02:35,940 --> 00:02:42,960 So I'm going to pass this one as a moderate to this, meaning that unless you are logged in before you 35 00:02:42,960 --> 00:02:44,460 can create a post. 36 00:02:44,640 --> 00:02:51,650 So let's make a request to the endpoint to make sure that everything is fine inside the post collection. 37 00:02:51,660 --> 00:02:59,490 This is the endpoint when I hit send, you can see that not authorized meaning unless I look in. 38 00:02:59,490 --> 00:03:02,910 So let me look in from here as that. 39 00:03:02,910 --> 00:03:08,640 Now I have successfully logged in, so let's hit send and let's look at the response. 40 00:03:09,150 --> 00:03:17,370 Well, we got a beautiful error, so let me check the terminal and we are doing something wrong about 41 00:03:17,370 --> 00:03:18,940 red dot body. 42 00:03:18,960 --> 00:03:24,330 So let me get back to the controller and instead of boy is buddy. 43 00:03:24,360 --> 00:03:26,670 All right, so let me hit send again. 44 00:03:28,140 --> 00:03:31,140 And it has been called successfully. 45 00:03:31,320 --> 00:03:34,800 So let's look at the road map now that we are locked in. 46 00:03:34,830 --> 00:03:38,160 We have access to the user as cost. 47 00:03:38,190 --> 00:03:43,560 User ID is equal to rec dot session. 48 00:03:46,330 --> 00:03:47,980 Dot user oath. 49 00:03:49,270 --> 00:03:54,490 So if you console console.log user ID, you're going to see the logged in user. 50 00:03:55,390 --> 00:03:56,680 Moment of truth. 51 00:03:58,820 --> 00:04:00,380 Let me check the terminal. 52 00:04:01,230 --> 00:04:08,820 And I have the log in user ID here so I can go ahead and find this user inside our DB. 53 00:04:09,120 --> 00:04:10,740 So let's go ahead and do that. 54 00:04:10,740 --> 00:04:12,660 Let me collapse this once. 55 00:04:13,460 --> 00:04:15,200 With exception of the posts. 56 00:04:15,320 --> 00:04:16,640 So here we go. 57 00:04:17,000 --> 00:04:29,060 Cost user found is equal to await the user model dot find by ID and then the ID is the log in user. 58 00:04:30,440 --> 00:04:34,340 Now we have gotten the log in user. 59 00:04:34,370 --> 00:04:39,110 The next step is that you go ahead and then create the post. 60 00:04:39,110 --> 00:04:40,550 And here we go. 61 00:04:40,580 --> 00:04:43,820 Const post created. 62 00:04:47,600 --> 00:04:52,490 Is equal to await the post model dot grid. 63 00:04:54,540 --> 00:04:57,210 And here I'll pass in the title. 64 00:04:59,240 --> 00:05:08,360 The description, the category, the user, and then the image. 65 00:05:08,600 --> 00:05:09,380 All right. 66 00:05:09,380 --> 00:05:20,180 For the user, we have it inside the session so I can assign the value as req dot session dot user off 67 00:05:20,960 --> 00:05:25,490 or I can use user found underscore ID. 68 00:05:26,480 --> 00:05:33,260 Because now I have the user in the DB and the ID of this user is equally the same as the one we store 69 00:05:33,260 --> 00:05:34,550 inside the session. 70 00:05:34,550 --> 00:05:41,750 So we can maintain this one or we can use the user found the underscore ID. 71 00:05:42,620 --> 00:05:43,220 All right. 72 00:05:43,220 --> 00:05:45,020 So for the image. 73 00:05:45,020 --> 00:05:50,750 For the meantime, let's remove the image here and let's create a post without an image. 74 00:05:50,750 --> 00:05:55,460 So let's also remove from here and we will come back to it as you move on. 75 00:05:55,910 --> 00:06:02,990 The next step is that we need to push the post created into the array of the log in user. 76 00:06:03,020 --> 00:06:13,220 So I'm going to add a comment here and say that push the post created into the array. 77 00:06:15,090 --> 00:06:17,850 Of U.S. Post. 78 00:06:20,240 --> 00:06:25,550 It's going to be, as a user found on that we have a field called post. 79 00:06:25,670 --> 00:06:30,950 If you doubt, let's look at the user model and this is what I'm referring to. 80 00:06:31,040 --> 00:06:39,020 We are pushing the ID of the post inside this property code post, but not the entire post. 81 00:06:39,020 --> 00:06:42,320 And this is what we call by reference. 82 00:06:42,320 --> 00:06:51,650 So here we are going to use push and we are going to push the idea of the post credit going to be post 83 00:06:51,650 --> 00:07:01,100 credit dot underscore ID and we can even post the entire post and mongoose will grab the ID and save 84 00:07:01,100 --> 00:07:03,500 it into this field of posts. 85 00:07:03,500 --> 00:07:08,510 But let's make it more descriptive by providing underscore ID. 86 00:07:09,110 --> 00:07:16,460 Then the last step is we need to save the user going to be as real, save the user because we've made 87 00:07:16,460 --> 00:07:23,540 changes to the user model going to be as await the user found dot save. 88 00:07:24,760 --> 00:07:31,290 To be able to create a post unless we remove the validation from the image for the meantime. 89 00:07:31,300 --> 00:07:33,670 So let's get back to the post model. 90 00:07:34,740 --> 00:07:42,750 Which is this and let's remove the required here for now and let's go ahead and then create a post. 91 00:07:43,170 --> 00:07:48,990 Remember, for the value of the category unless we use one of these. 92 00:07:48,990 --> 00:07:56,850 So let's get back to the endpoint where we can create and let's click on body and let's pass in the 93 00:07:56,850 --> 00:07:57,690 payload. 94 00:07:58,020 --> 00:08:03,570 First is the title of the post, and I'll call this one as Node.js. 95 00:08:03,690 --> 00:08:13,500 And then the description is going to be the best post and then the category. 96 00:08:15,290 --> 00:08:18,320 Is going to be JavaScript. 97 00:08:18,620 --> 00:08:24,440 So let's check the category where yes, indeed, we have JavaScript here. 98 00:08:24,890 --> 00:08:31,100 So that's what we need for now for the user is going to add it automatically because we are using the 99 00:08:31,100 --> 00:08:33,980 log in user or the user found ID here. 100 00:08:34,010 --> 00:08:35,659 So moment of truth. 101 00:08:35,690 --> 00:08:40,880 Let me send back the post created and then let me change this one to data. 102 00:08:41,700 --> 00:08:43,830 So now let me hit send. 103 00:08:45,120 --> 00:08:53,790 And we have the post being created and we have a field code user, meaning the author of this particular 104 00:08:53,790 --> 00:08:54,540 post. 105 00:08:54,630 --> 00:08:58,110 So what about creating a post with an image? 106 00:08:58,140 --> 00:09:00,510 Let's get into that in the next video.
