WEBVTT 00:03.730 --> 00:05.230 Hey, did everyone taste here? 00:05.230 --> 00:09.460 And in this video we're going to go through and work with the controllers for our orders. 00:09.490 --> 00:13.860 Now, the only difficult part was the order was just the schema design. 00:13.870 --> 00:16.330 It's really a long and lengthy schema, and that's it. 00:16.330 --> 00:20.620 The rest of the things are pretty easy and in fact we have done so much of the work now things should 00:20.620 --> 00:22.770 be looking absolutely easy. 00:22.780 --> 00:27.430 So let's go into the controller, let's create a new file and I'm going to call this one as simply order 00:27.430 --> 00:29.740 controller dogs. 00:29.740 --> 00:35.290 Of course, we will be working on the routes and other things, but first let's finish up all of our 00:35.290 --> 00:39.730 control and in fact, majority of the one that we have and then we're going to set up routes for them. 00:39.730 --> 00:43.420 So the first thing is I would like to go ahead and bring the model of the order itself. 00:43.420 --> 00:44.590 So let's go ahead and do that. 00:44.590 --> 00:46.990 That is a pretty simple stuff, pretty ordinary stuff. 00:46.990 --> 00:48.280 We have done it many times. 00:48.280 --> 00:52.780 One directory back inside the models, we have the order, there we go. 00:52.840 --> 00:56.710 We are also going to need the model of the product as well. 00:56.710 --> 01:01.900 So let's go ahead and do that because there is going to be a time when receiving once we have received 01:01.900 --> 01:05.590 the order, we need to change something into the product model, which is the stock. 01:05.590 --> 01:07.210 So for that, we are going to need this. 01:07.210 --> 01:14.440 So let's go ahead and import product and the product is going to be coming from the model, which is 01:14.440 --> 01:14.980 product. 01:14.980 --> 01:15.730 There we go. 01:16.720 --> 01:20.620 Apart from this, let's go ahead and borrow some stuff from the payment controller. 01:21.100 --> 01:21.460 Yeah. 01:21.460 --> 01:27.580 So big promise we can borrow from here and again just saving some time and I guess that's pretty much 01:27.580 --> 01:27.730 it. 01:27.730 --> 01:29.470 That's all what we need in this case. 01:29.920 --> 01:31.990 Okay, let's go ahead and export a few methods. 01:31.990 --> 01:36.580 So let's go ahead and first say export DOT and this one is going to be create order. 01:36.580 --> 01:37.870 So let me just walk you through again. 01:37.870 --> 01:42.550 So these are all the routes of the order that we have to work on with. 01:42.970 --> 01:47.530 So let me go ahead and minimize this, zoom out a little bit and there we go. 01:48.400 --> 01:50.740 So these are all the routes that we have to work on. 01:50.890 --> 01:55.780 So the first one is actually to create order that get single order, get the order for the log. 01:55.780 --> 01:58.360 Then user admin should be able to get all the orders. 01:58.360 --> 02:03.490 Admin should be able to update any particular one order admin should be able to delete one order. 02:03.490 --> 02:04.420 So pretty simple stuff. 02:04.420 --> 02:05.800 Nothing groundbreaking here. 02:06.070 --> 02:09.400 So let's go ahead and call this one as simply create order. 02:09.400 --> 02:11.080 Sounds a good name for this one. 02:11.440 --> 02:16.090 And we're going to say this wrap around everything inside the big promise just like that. 02:16.600 --> 02:19.060 And let's go ahead and use a sync. 02:19.660 --> 02:23.800 And for that we are going to say request, response and the next. 02:26.380 --> 02:27.190 And there we go. 02:27.190 --> 02:32.740 Now we're going to work on a whole lot of things are going to come to us from the request body. 02:32.740 --> 02:37.110 So let's go ahead and say, hey, we want to extract a lot of things that are going to come from request 02:37.110 --> 02:37.900 dot body. 02:37.900 --> 02:41.560 So let's go ahead and see that how many things are going to come in. 02:41.560 --> 02:48.160 So for this, I would like to split my editor into this one and I would like to open up different file 02:48.160 --> 02:50.880 into this one, which is going to be model and ordered on. 02:50.890 --> 02:56.200 JS Okay, so this will help me to actually grab the things a little bit easier from here. 02:56.230 --> 02:59.080 Let's go ahead and see how many of the items are going to come here. 02:59.080 --> 03:02.980 So first is a shipping info, so I'm going to go ahead and say shipping info. 03:03.670 --> 03:05.560 This will be coming up from the request body. 03:05.560 --> 03:07.450 Yes, the entirety of the giant object. 03:07.450 --> 03:11.590 I expect somebody to pass me from the front and then comes up is the user. 03:11.590 --> 03:13.750 User will not come from the body itself. 03:13.750 --> 03:18.910 We need to access the user from request to user our middleware, other items. 03:18.910 --> 03:19.990 Yes, I expect this one. 03:19.990 --> 03:21.250 So I can actually copy this. 03:21.250 --> 03:23.020 Yeah, that's actually much more easier. 03:23.350 --> 03:25.750 So order item is going to come from here. 03:26.110 --> 03:30.520 Then we have this payment info that also should come up from the front end because somebody guy who 03:30.520 --> 03:36.610 has requested first the payment from the back end, then once the payment is successful, he should 03:36.610 --> 03:40.390 receive that data and then he should make a request for placing the order. 03:40.390 --> 03:43.510 So we expect that this payment info also should come from there. 03:43.510 --> 03:48.880 This is the kind of architecture or the flow of the application that we have planned up to X amount. 03:48.880 --> 03:52.900 Yes, you should give it to me and then the shipping amount. 03:52.930 --> 03:55.450 Of course, I expect this to come from the front end. 03:56.740 --> 04:04.450 And apart from this then we have total amount also expected to come from the front end and forgot a 04:04.450 --> 04:04.770 comma. 04:04.780 --> 04:05.470 There we go. 04:06.400 --> 04:10.660 And then order status has a default value so I'm not bothered about that part. 04:10.660 --> 04:13.960 Deliver that this is also going to have a date. 04:14.440 --> 04:17.020 So this is not going to be filled as of now. 04:17.020 --> 04:18.360 This is also not a required field. 04:18.370 --> 04:23.470 Once the delivery has been done, then we are going to change this field created that is automatically 04:23.470 --> 04:24.340 going to have the value. 04:24.340 --> 04:24.850 So default. 04:24.850 --> 04:28.960 Now the only thing that's remaining is that how we are going to process this user. 04:30.310 --> 04:31.480 Now that's it. 04:31.480 --> 04:38.170 We can actually close this guys and we can actually save this one up here and then we can close this 04:38.170 --> 04:38.440 one. 04:39.100 --> 04:44.410 So now we have extracted on the information from the order request body as well. 04:44.440 --> 04:45.910 Now let's go ahead and create an order. 04:45.910 --> 04:51.430 So for creating the order, we are going to simply use order, create simple method and pass on a big 04:51.430 --> 04:53.020 gigantic object into it. 04:53.140 --> 04:58.870 The object is going to look like this, so all the values are going to just pass it on like this. 04:59.080 --> 05:01.900 The only value that is now here is the user. 05:01.900 --> 05:03.460 So let's go ahead and say user. 05:03.460 --> 05:06.250 The user is going to come from request dot user. 05:06.250 --> 05:09.160 User is the entire object that we have injected in the middleware. 05:09.160 --> 05:13.540 So I have to say dot ID is a dot ID or underscore ID. 05:13.570 --> 05:18.430 No, this is going to be a dot underscore ID because this user object is coming up from the MongoDB 05:18.430 --> 05:18.850 itself. 05:18.850 --> 05:20.290 So just testing you out. 05:20.410 --> 05:22.000 Okay, so this is all done. 05:22.000 --> 05:25.870 And if the order was successfully created, let's go ahead and hold this order into available. 05:25.870 --> 05:28.150 So we're going to call this one as simply order. 05:28.180 --> 05:29.740 That is going to be a wait. 05:29.740 --> 05:32.590 There we go further down the road. 05:32.590 --> 05:35.470 We just need to send the response or rest dot status. 05:35.470 --> 05:39.250 They should be looking all like I can do it very, very familiar stuff now. 05:39.370 --> 05:42.310 And that is a kind of a win for me. 05:42.730 --> 05:42.970 Okay. 05:43.000 --> 05:48.130 So what we're going to do is, again, success is going to be true and we are going to send order as 05:48.130 --> 05:48.520 a test. 05:48.520 --> 05:49.300 That's it. 05:49.300 --> 05:51.010 So told you, it's really simple. 05:51.010 --> 05:56.500 Now, one thing I would like to mention here, which is very, very crucial to you, that you might 05:56.500 --> 06:00.970 want to test this out from the postman itself, but there is a thing that you need to actually kind 06:00.970 --> 06:06.010 of walk through if you are testing it with the postman or even from the front end documentation. 06:06.010 --> 06:10.960 So when I'm saying this order items, let me open this order item and show you something very, very 06:10.960 --> 06:11.560 tricky. 06:11.650 --> 06:13.650 So order item and I open this up. 06:13.660 --> 06:17.650 This is a product of mongoose dot schema, dot object ID. 06:17.680 --> 06:22.480 So what is going to happen when you are going to try to build this array of order items? 06:22.480 --> 06:26.590 You might be tempted in the postman itself that, Hey, where is the postman? 06:26.590 --> 06:29.590 This is the postman that you might be creating a new route. 06:29.590 --> 06:33.610 And inside this, let me just go ahead and add a sample one here. 06:33.610 --> 06:40.060 So just like this and inside the body, raw JSON data. 06:40.060 --> 06:45.910 So you might be saying, hey, this is my order items, let me go ahead and use this. 06:46.690 --> 06:51.640 And codes, order my gain lowercase order items. 06:53.800 --> 06:56.080 And inside this, this is going to be an array. 06:56.080 --> 07:01.060 So you might be tempted to put up all the values like this and then you might be thinking, okay, so 07:01.060 --> 07:04.570 this order item is a big gigantic object which has name and all of that. 07:04.570 --> 07:07.420 So let's place the name and then I like to place the product. 07:07.690 --> 07:12.490 So you'll come here and say, Hey, I would like to add a name here, so go ahead and say this name 07:12.790 --> 07:15.730 and something like this and say test name. 07:15.730 --> 07:19.240 Then you might be thinking, okay, I need to now add the product ID as well. 07:19.240 --> 07:24.940 So you'll put up a comma and you will say product ID or just the product itself. 07:24.940 --> 07:30.520 And this expects you to pass on an object ID and you might be very tempted to just grab something like 07:30.520 --> 07:31.330 get all products. 07:31.330 --> 07:35.500 I can grab order ID from here, copy it up here and paste it up here. 07:35.530 --> 07:40.360 Now, although in majority of the cases this is going to work, but this is not truly the correct way 07:40.360 --> 07:41.260 of handling the things. 07:41.260 --> 07:45.940 If you are going to do and add things like this, your order is not going to be truly searchable because 07:45.940 --> 07:50.500 this is a string, although your mongoose is going to accept that and is going to probably put this 07:50.500 --> 07:55.210 thing because we haven't done a proper check of checking whether this is a valid mongoose ID or not. 07:55.210 --> 08:01.720 But this notice here it says object ID and then inside the parenthesis they are saying this is a long 08:01.720 --> 08:02.530 string number. 08:02.530 --> 08:03.730 So there is a difference. 08:03.730 --> 08:06.820 I have repeatedly said that this is not entirely adjacent data. 08:06.820 --> 08:11.320 This is a based on data, based on gives you some of the additional features and functionality. 08:11.320 --> 08:13.690 So testing of this is really, really tricky one here. 08:13.690 --> 08:18.040 So that's why I'm not going to do this right now, but I'll just want to keep this information with 08:18.040 --> 08:18.160 you. 08:18.160 --> 08:23.830 That passing just the JSON is not the way this is an object ID and object ID should be treated differently 08:23.830 --> 08:24.970 as compared to the JSON. 08:24.970 --> 08:29.170 This is a baseline, so just keep that in mind and that's all is expected as of now. 08:29.170 --> 08:34.660 Already we have done way above that what should be done in a in a kind of a beginner friendly course. 08:34.660 --> 08:35.410 So there we go. 08:35.440 --> 08:36.820 Your create order is all done. 08:36.820 --> 08:39.940 Let's go ahead and create another method in the next video.
