WEBVTT 00:03.970 --> 00:08.560 Hey, did everyone that they shared and in this video we'll be writing model for our product itself 00:08.560 --> 00:10.390 and feel free to add more products. 00:10.390 --> 00:14.380 Now you have full experience of how to handle that, so it shouldn't be a big deal. 00:14.560 --> 00:19.180 Now, this one is going to be a little bit of a longer video because we have so much of things to add 00:19.180 --> 00:22.900 into the into the model of the product itself. 00:22.900 --> 00:24.730 So it's going to take a little bit while. 00:24.730 --> 00:26.410 So have patience on that part. 00:26.590 --> 00:28.540 First, let's go ahead and set up our model. 00:28.540 --> 00:29.470 We have already written that. 00:29.470 --> 00:30.640 So it's inside the product. 00:30.870 --> 00:32.620 So how do we write our model itself? 00:32.620 --> 00:34.600 It's fairly, fairly simple. 00:34.840 --> 00:40.150 So let's go ahead and say, Hey, Mongoose, please help me to write a model. 00:40.150 --> 00:45.060 And it's going to help you by saying require mongoose. 00:45.670 --> 00:48.430 Okay, so we use a simple method from the mongoose itself. 00:48.430 --> 00:53.560 First, let's hold that into a variable and let's call this one as product schema. 00:54.400 --> 00:55.030 Schema. 00:55.030 --> 00:55.780 There we go. 00:55.870 --> 01:00.910 And the method from the mongoose itself is going to say, Hey, just help him to create a schema. 01:00.910 --> 01:04.300 So I need to say new because it's a class here. 01:04.300 --> 01:07.840 So new mongoose dot schema. 01:07.840 --> 01:08.410 There we go. 01:08.410 --> 01:12.550 And inside that we play some a whole lot of objects, whatever we actually need up there. 01:12.790 --> 01:18.490 But first, I always love to export this one, so I'm going to go ahead and save module exports so anybody 01:18.490 --> 01:19.660 can import that. 01:19.660 --> 01:22.600 And we're going to say, Hey, Mongoose, help me to create a model. 01:22.600 --> 01:26.020 So Mongoose model model takes to parameter that. 01:26.020 --> 01:27.400 What do you want to call to a model? 01:27.400 --> 01:31.270 And just with the convention, we always call with the uppercase letter, but I know that inside the 01:31.270 --> 01:33.730 DB it will go as products all lowercase. 01:33.940 --> 01:35.440 What schema do you want to use? 01:35.440 --> 01:37.810 I want to use a schema of product schema. 01:37.810 --> 01:38.500 There we go. 01:39.050 --> 01:39.220 Okay. 01:39.520 --> 01:42.010 So this is the most basics that we got up here. 01:42.010 --> 01:46.030 Now we need to actually bring some data and we'll be bringing data from here itself. 01:46.060 --> 01:49.120 So I'll be just copying everything from here. 01:49.120 --> 01:52.600 It will help me to actually get easy check up here. 01:53.050 --> 01:58.840 I'll come here and add this and obviously I'll remove this, all of that in a minute. 01:58.840 --> 02:01.570 But first, I'm going to go ahead and comment this out. 02:02.020 --> 02:02.530 Okay. 02:02.530 --> 02:05.620 So let's go ahead and add all of the data one by one. 02:05.620 --> 02:07.780 So let's go ahead and do that first. 02:07.780 --> 02:08.920 Let's start with the name. 02:08.920 --> 02:10.510 So we're going to go ahead and say name. 02:10.510 --> 02:13.870 I can of course, say string directly here, but I have a lot more to handle. 02:13.870 --> 02:17.290 So that's why I'm going to say define properties one by one. 02:17.290 --> 02:21.130 So first one is it's going to be of type string, nice and easy. 02:21.130 --> 02:23.590 Now the name obviously is going to be required fields. 02:23.590 --> 02:28.450 So we're going to go ahead required and not only just true we'll pass on an array through is the first 02:28.450 --> 02:33.490 property or zeroth property in this case and we're going to provide the error message as well. 02:33.490 --> 02:41.860 So please provide product, product name. 02:42.970 --> 02:43.180 Okay. 02:43.270 --> 02:44.770 So error message is also handled. 02:44.770 --> 02:47.290 We are also going to use a property, another one trim. 02:47.290 --> 02:49.600 I'm pretty sure most of you have heard about this property. 02:49.600 --> 02:52.020 It's really an easy property to work on with. 02:52.060 --> 02:57.070 If you have any additional spaces at the end of your product name, you can go ahead and remove that. 02:57.070 --> 02:59.950 You can actually use this property inside the email as well. 03:00.100 --> 03:02.050 Just a cautionary stuff. 03:02.410 --> 03:06.820 Now you can also go ahead and define what kind of maximum length you want to support in this case. 03:06.820 --> 03:12.670 So I'm going to assume that probably 120 words is characters is not words. 03:12.670 --> 03:15.610 120 characters is more than enough for a product name. 03:15.940 --> 03:18.280 Let's give a provide a message to the user as well. 03:18.520 --> 03:28.180 That product name should not be more than 120 characters. 03:28.180 --> 03:29.020 So there we go. 03:29.290 --> 03:33.490 Okay, let's go ahead and do a copy of this so that it helps us a little bit. 03:33.490 --> 03:37.390 First, put a comma and now let's go ahead and make a copy of this. 03:38.050 --> 03:38.290 Okay. 03:38.380 --> 03:40.870 So next one that we have is the pricing. 03:40.870 --> 03:43.870 So let's go ahead and say I want to give you a price here. 03:44.140 --> 03:47.200 Now, the price is obviously not going to be a string. 03:47.200 --> 03:50.080 It's rather going to be a number required. 03:50.080 --> 03:50.560 True. 03:50.590 --> 03:53.590 We are going to say please provide product price. 03:53.710 --> 03:54.640 Nice error message. 03:54.640 --> 03:56.560 They're very consistent trim. 03:56.560 --> 03:58.000 We don't need to do a trim. 03:58.270 --> 04:04.600 We're going to go ahead and remove this maxlength surely I can go ahead and say, hey, maxlength is 04:04.600 --> 04:09.640 going to be, let's just say five now these are digits since we are talking in the case of numbers. 04:09.640 --> 04:10.750 So these are the digits. 04:10.750 --> 04:13.300 I don't want any product to be more than five digits. 04:13.300 --> 04:19.330 Surely I would love to sell a t shirt of probably five lakh rupees or 20 lakh rupees, but I think five 04:19.330 --> 04:21.280 digit is good enough. 04:21.280 --> 04:26.560 So product price should not be more than. 04:28.810 --> 04:29.800 Five digits. 04:29.800 --> 04:32.200 And again, these are not digits counting from the zero. 04:32.200 --> 04:37.330 So five digit, I guess it's more than if you can go ahead and change this probably to six. 04:37.330 --> 04:39.040 Maybe you want to sell expensive one. 04:39.040 --> 04:40.930 You get the idea how this is being done. 04:41.770 --> 04:42.250 Okay. 04:42.340 --> 04:44.080 Next up is the description. 04:44.080 --> 04:45.970 So let's go ahead and add this one. 04:46.930 --> 04:47.350 Okay. 04:47.740 --> 04:51.010 Now let's go ahead and change this one to this. 04:52.700 --> 04:53.660 Corruption. 04:55.530 --> 04:56.310 Description. 04:56.310 --> 04:57.000 There we go. 04:57.260 --> 04:57.570 Okay. 04:57.570 --> 04:59.910 So this one is going to be of type string. 05:00.450 --> 05:05.520 And in the description, we are going to not put a maximum length because description can be long and 05:05.520 --> 05:08.040 maybe there are future plans of supporting more stuff. 05:08.040 --> 05:11.720 But we're going to say required because this is kind of important. 05:11.730 --> 05:15.060 Otherwise our application will look weird if this will be optional. 05:15.150 --> 05:19.650 So we're going to say please provide product description. 05:20.400 --> 05:22.740 Next one is a photos. 05:22.740 --> 05:24.840 So let's go ahead and work on with the photos. 05:24.840 --> 05:32.190 So let's go ahead and copy this, paste that OC The photos is going to be an interesting one. 05:32.190 --> 05:36.180 Not really interesting because something like this, we have already handled that. 05:36.180 --> 05:37.860 So shouldn't be a big deal there. 05:38.550 --> 05:44.520 Let's go ahead and call this one as photos now this time at the at the model that we have previously 05:44.520 --> 05:49.620 worked the user itself, this is just a photo because we were adding just one photo in this case, this 05:49.620 --> 05:53.400 is going to be a photos because we are adding a whole lot more there. 05:53.400 --> 05:56.910 So this time it's not going to be an object directly. 05:56.910 --> 06:00.360 It's rather going to be an array so that somebody can actually loop through it. 06:00.360 --> 06:03.960 And these are all the things you have to take care of while designing a model itself. 06:03.960 --> 06:07.170 And inside this we're going to add an object. 06:07.170 --> 06:12.000 Each individual object will have two properties ID and the security URL. 06:12.000 --> 06:14.040 So something like we have already worked with that. 06:14.040 --> 06:20.640 So ID again, we are going to go ahead and say, hey, this one is going to be of type. 06:20.640 --> 06:21.420 There we go. 06:21.750 --> 06:26.220 Type of the ID is going to be string and this one is going to be required. 06:26.220 --> 06:29.340 So yes, we need images up there. 06:29.670 --> 06:31.740 So we are going to say required. 06:31.740 --> 06:37.620 So at least somebody passes us one image and that one image is going should have an ID and should have 06:37.620 --> 06:39.990 a security model as well. 06:40.170 --> 06:42.120 So required is going to be. 06:42.630 --> 06:43.350 Come on. 06:43.650 --> 06:45.360 Required is going to be true. 06:46.650 --> 06:54.750 And now we can put up a comma and make a copy of this one, and we're going to call this one as a secure 06:54.930 --> 06:58.410 URL type a string required is true. 06:58.440 --> 06:59.580 We don't need this trailing. 06:59.580 --> 07:00.420 And there we go. 07:00.450 --> 07:06.690 Now we can have as many objects inside this ETA, but each object should carry these two properties. 07:06.690 --> 07:09.060 So this is how we are going to handle the photos. 07:09.600 --> 07:11.190 Okay, so this is all good. 07:11.190 --> 07:18.540 Now, coming up after the photos, I need to copy this one just to save some minutes, some seconds. 07:18.720 --> 07:19.470 There we go. 07:20.010 --> 07:22.620 So after the photos, we got into the categories. 07:22.620 --> 07:24.000 Now, this is interesting one. 07:24.000 --> 07:28.830 Now surely I could have created another model just for the categories, but since in the discussion 07:28.830 --> 07:33.720 we came to know that it's short sleeves, long sleeves, sweatshirts and the hoodies as well. 07:33.720 --> 07:35.940 So that's why we are super easy on that part. 07:35.940 --> 07:41.460 But once you know how to inject users into the product itself, I'm pretty sure it shouldn't be a tough 07:41.460 --> 07:44.220 to add categories into the product because they are just models. 07:44.220 --> 07:47.190 Once you know how to inject one model, you can add other models as well. 07:47.430 --> 07:52.230 So let's go ahead and call this one as category, not categories. 07:52.260 --> 07:54.180 It is kind of a makes sense. 07:54.540 --> 07:56.460 Okay, this is going to be a type string. 07:56.460 --> 07:58.680 And again, did we made a mistake in the string? 07:58.680 --> 08:00.090 Yep, we made a mistake. 08:01.080 --> 08:01.860 There we go. 08:01.860 --> 08:03.960 So a small typo there just fixed it. 08:04.470 --> 08:05.700 And this one also. 08:06.120 --> 08:11.610 Okay, so categories is going to be type string and we are going to say true and we are going to provide 08:11.610 --> 08:12.210 a message. 08:12.210 --> 08:12.930 Please. 08:14.410 --> 08:17.470 Select categories. 08:18.920 --> 08:20.330 Category from. 08:22.160 --> 08:28.220 We are going to go ahead and save from and let's say Daesh and this one is going to be only short. 08:30.160 --> 08:32.530 Dash sleeves. 08:34.730 --> 08:40.490 And we're going to say long dash sleeves or it can be. 08:41.890 --> 08:44.890 Sweat does shirt. 08:46.410 --> 08:47.760 Or it can be hoodies. 08:47.760 --> 08:49.600 So we're going to go ahead and say hoodies. 08:49.620 --> 08:54.780 Now we are why we are providing message like this, because we'll be providing the option to select 08:54.780 --> 08:55.230 here. 08:55.260 --> 08:59.880 Now, in case you want to any time restrict the users option in is always your best friend. 08:59.880 --> 09:04.140 So we're going to say, hey, we're going to provide an enum and inside this enum we are going to go 09:04.140 --> 09:05.580 ahead and provide the values. 09:05.580 --> 09:06.450 So there we go. 09:06.750 --> 09:10.470 Values is always an error in the enum, so let's go ahead and provide these. 09:10.470 --> 09:15.600 So we're going to go ahead and say, hey, this one you can choose from short dash sleeves. 09:16.440 --> 09:19.470 And again, you have to provide the exact name that you are mentioning here. 09:19.470 --> 09:22.710 Make sure it is not case and not uppercase lowercase. 09:22.710 --> 09:24.120 Make sure you are consistent there. 09:24.780 --> 09:27.420 Long dash sleeves. 09:28.440 --> 09:29.490 We are going to go ahead. 09:29.490 --> 09:33.900 Another one which is going to be sweat again in the codes. 09:36.340 --> 09:37.360 Come on. 09:37.690 --> 09:39.700 Sweat shirt. 09:40.730 --> 09:42.440 If I can write that finally. 09:42.920 --> 09:44.900 And the final one is hoodies. 09:45.650 --> 09:49.580 Now, it makes sense in this case, since we have only these ones, in case you want to give the user 09:49.580 --> 09:53.300 ability to just kind of a CRUD functionality with the categories as well. 09:53.300 --> 09:55.160 We have already done that in the main course. 09:55.160 --> 09:57.220 You might want to check that out, but I don't think so. 09:57.230 --> 09:59.390 It should it be a big deal for you now? 09:59.870 --> 10:02.810 Okay, so this is all good and it looks great. 10:02.810 --> 10:10.550 And by the way, you can also provide a message and in case somebody provides a category which is something 10:10.550 --> 10:14.830 else than this, then specifically you can go ahead and provide a message for that. 10:14.840 --> 10:19.940 Now this message required is going to come in whenever somebody says that I'm not providing you any 10:19.940 --> 10:24.410 category, but if somebody chooses something else, then we can go ahead and provide a message here. 10:24.410 --> 10:26.450 So the property is known as message. 10:26.450 --> 10:27.140 There we go. 10:27.320 --> 10:30.890 And the message goes just like in the codes that please. 10:33.100 --> 10:34.610 We can actually copy this. 10:34.630 --> 10:35.890 That would be easier. 10:36.340 --> 10:43.600 We're going to go ahead and say please select category only from short sleeves. 10:44.260 --> 10:44.860 There we go. 10:44.860 --> 10:47.380 From short sleeves, long sleeves, sweatshirt. 10:49.520 --> 10:50.450 And howdy. 10:50.480 --> 10:51.410 So there we go. 10:51.590 --> 10:57.050 So now this is really easy and gave us a chance to explore it a little bit more about how to explode 10:57.080 --> 10:57.770 enemies. 10:58.110 --> 10:59.420 Okay, so category is all done. 10:59.500 --> 11:01.220 Now let's go ahead and work on with the brand. 11:01.250 --> 11:04.400 So after the category, let's go ahead and add a brand. 11:05.390 --> 11:07.570 So brand is going to be really simple. 11:07.580 --> 11:09.530 Let's go ahead and work on like that. 11:09.530 --> 11:11.520 And in the brand we're going to say type. 11:11.540 --> 11:13.970 The idea behind the brand is really simple right now. 11:13.970 --> 11:19.610 It's just learn code online, but maybe tomorrow I want to sell t shirts of Adidas or maybe something 11:19.610 --> 11:21.170 else, some cocreator on YouTube. 11:21.170 --> 11:23.180 So that's why we are adding a brand here as well. 11:23.420 --> 11:27.560 The required is going to be same, just like we have talked probably many times. 11:27.920 --> 11:28.520 True. 11:28.520 --> 11:34.730 And we're going to say please add a brand for clothing. 11:36.950 --> 11:37.970 What else we got? 11:38.330 --> 11:39.770 We got rating here as well. 11:39.770 --> 11:42.410 Now, this rating is interesting ratings. 11:42.410 --> 11:44.330 So let's go ahead and add this one. 11:45.900 --> 11:47.340 So there we go. 11:47.370 --> 11:48.260 Really simple. 11:48.270 --> 11:51.450 We don't need too much explanation on ratings. 11:51.480 --> 11:55.320 It's going to be of type number so that later on I can average it out. 11:55.320 --> 11:57.570 I can find a lot more stuff. 11:57.690 --> 12:01.680 And this is not going to be required because user will not pass on this one. 12:01.680 --> 12:06.300 We need to just provide a default because every single product will obviously have some of the ratings, 12:06.300 --> 12:11.760 but by default everything is off is going to start with a zero rating as the user will give on more 12:11.760 --> 12:12.150 ratings. 12:12.150 --> 12:13.680 Five star to start, three star. 12:13.680 --> 12:16.050 I'll add on an average into this rating. 12:16.050 --> 12:17.010 So I have to do that. 12:17.010 --> 12:19.440 I'll manually work on these things. 12:19.530 --> 12:20.280 Let's move on. 12:20.280 --> 12:21.270 What else we got? 12:21.390 --> 12:22.110 We got ratings. 12:22.110 --> 12:24.000 We got a number of reviews as well. 12:24.000 --> 12:25.200 So a number of reviews. 12:25.200 --> 12:25.890 Really simple. 12:25.920 --> 12:27.600 How many people have actually reviewed it? 12:27.600 --> 12:30.750 As soon as a new rating comes in, I'll just add one to this one. 12:30.750 --> 12:31.650 So really simple. 12:31.800 --> 12:38.070 We're going to go ahead and say number of reviews and that's going to be like this. 12:38.340 --> 12:45.450 This is going to be a type of number and obviously by default, there is going to be no rating. 12:45.450 --> 12:48.990 So the default says zero. 12:49.890 --> 12:50.610 Okay. 12:51.240 --> 12:53.370 Just a few more then this reviews. 12:53.370 --> 12:54.900 Now, this is an interesting one. 12:54.900 --> 12:58.800 We already got a discussion on this one, but we'll have a talk, small talk here as well. 12:59.010 --> 13:00.480 Let's go ahead and copy this. 13:00.480 --> 13:02.160 Put up in this guy. 13:02.580 --> 13:02.940 Okay. 13:02.940 --> 13:03.780 So what is this? 13:03.780 --> 13:05.550 This is actually reviews. 13:05.550 --> 13:09.420 So all the reviews, every single product is going to get a reviews. 13:09.420 --> 13:12.990 So whenever you add a review, it is associated with the product itself. 13:12.990 --> 13:14.970 That's why we are keeping it in the model itself. 13:14.970 --> 13:20.160 Now surely you can keep it into separate model and add an injection or something like this, but we 13:20.160 --> 13:20.940 won't be doing that. 13:20.940 --> 13:22.650 We'll be just keeping it as reviews. 13:22.710 --> 13:27.990 Now obviously this reviews is going to be array because maybe there are so many errors somebody wants 13:27.990 --> 13:28.950 to iterate through with it. 13:28.950 --> 13:30.150 So that is obvious. 13:30.180 --> 13:32.520 Now what do you want to inject into this one? 13:32.520 --> 13:36.870 The first thing that I would like to add is who is the user who has given me the ratings? 13:36.870 --> 13:39.060 Only logged in user can give me the rating. 13:39.270 --> 13:42.990 So how we inject this one, this is really, really simple. 13:42.990 --> 13:44.460 Like ridiculously simple. 13:44.580 --> 13:49.350 All you got to do is simply use Mongoose again after the column, of course. 13:49.350 --> 13:59.070 So I'll go to say is Mongoose dot schema and then just go ahead and say object id make sure this is 13:59.070 --> 14:00.240 exactly looks like this. 14:00.240 --> 14:01.650 Oh capital and I capital. 14:01.650 --> 14:04.680 So what I'm saying here is let me walk you through inside this. 14:04.680 --> 14:10.230 You have noticed that every single object that you add inside the database, it has this object. 14:10.230 --> 14:14.490 ID remember it is written as o capital and a capital so object ID. 14:14.490 --> 14:19.800 So what I'm saying is I will give you this object ID now in the object ID when you actually add them. 14:19.800 --> 14:24.930 It looks like just a long string with numbers and some letters, but it's actually a based on field 14:24.930 --> 14:27.120 just like JSON but based on field. 14:27.120 --> 14:28.860 Now this field has all of this numbers. 14:28.860 --> 14:33.150 So what I'm saying is whenever I'll be creating this, I'll inject this entire value up here. 14:33.150 --> 14:34.410 That's why I'm referencing it. 14:34.410 --> 14:38.820 That that there will be an object ID, mongoose, object ID that will come to you. 14:38.850 --> 14:41.250 You also have to pass on that. 14:41.250 --> 14:43.110 Hey, anything can be an object ID. 14:43.140 --> 14:46.590 Maybe it can come up from user, it can come up from product itself. 14:46.590 --> 14:48.450 Maybe you are creating categories from itself. 14:48.450 --> 14:52.710 So from where it should be coming up so that I can go ahead and validate it myself. 14:52.710 --> 14:57.180 So then you have to go ahead and provide a ref here, which is a reference that I'm going to go ahead 14:57.180 --> 14:58.290 and say user. 14:58.770 --> 15:03.570 Now this user needs to be exactly same as what you are calling it up here. 15:03.810 --> 15:05.400 Let me show you at the end of it. 15:05.400 --> 15:07.170 So this is what I'm calling it. 15:07.170 --> 15:09.420 I need to pass on exactly that in the reference. 15:09.420 --> 15:13.410 If you're calling it as category or whatever you are calling in, you just have to do this. 15:13.410 --> 15:15.390 Now, this two line of code, that's it. 15:15.390 --> 15:18.810 That's how you can inject another document value into other document. 15:18.810 --> 15:19.860 That's all it takes. 15:20.250 --> 15:25.050 Now we're going to go ahead and say this is a required field, so we're going to go ahead and say required 15:25.050 --> 15:26.070 a is true. 15:26.250 --> 15:31.170 So now any time a review comes in, they have to give me this user object. 15:31.710 --> 15:36.150 Now further down the road, we probably also would like to add a name of this. 15:36.150 --> 15:39.060 It will look good at the time of showing the review. 15:39.060 --> 15:42.060 So let's go ahead and say, hey, I need to provide a type. 15:42.240 --> 15:49.500 The type is going to be a string scroll a little bit and let's go ahead and move on to required. 15:51.130 --> 15:51.570 Okay. 15:51.580 --> 15:52.600 Now you can see it. 15:53.350 --> 15:59.950 Now you're going to see that this is a type and required is going to be true. 16:02.170 --> 16:02.650 Okay. 16:02.650 --> 16:03.970 So these are the basic field. 16:04.000 --> 16:08.380 Of course, whenever you are taking a rating, you need to take the rating a number between one and 16:08.380 --> 16:08.950 five. 16:08.950 --> 16:10.810 You can provide an enum here as well. 16:10.810 --> 16:12.820 That would be awesome, but I don't think so. 16:12.820 --> 16:16.270 It is required again, but surely having that is not a bad idea at all. 16:16.270 --> 16:18.700 And a comment that what do you want to say in the rating itself? 16:18.700 --> 16:19.630 So really simple. 16:19.720 --> 16:22.870 So we're going to go ahead and say, hey, this is the rating that you are providing. 16:22.870 --> 16:24.910 This rating will be of type number. 16:24.910 --> 16:30.880 Not like that, of course, like this type number. 16:31.030 --> 16:32.290 Come on. 16:32.560 --> 16:33.760 There we go. 16:33.940 --> 16:34.180 Okay. 16:34.210 --> 16:35.860 So this is going to be a type of number. 16:35.860 --> 16:37.480 Surely this is also required field. 16:37.480 --> 16:42.040 So what I'll do is I'll copy this and I'll paste it up here. 16:43.210 --> 16:44.560 Okay, so this is all done. 16:44.560 --> 16:46.420 Now, next thing is the comment itself. 16:46.420 --> 16:50.020 So let's go ahead and add a comma and give itself a copy. 16:50.320 --> 16:51.100 There we go. 16:52.610 --> 16:58.130 So this one is going to be a feedback, comment, whatever you want to call that, it's up to you. 16:58.310 --> 16:59.840 This is going to be a string. 16:59.840 --> 17:01.080 So all these fields. 17:01.100 --> 17:05.090 So now my review itself, or reviews rather itself is an array. 17:05.090 --> 17:10.250 And whenever you want to add any value into this array, you have to provide me for things. 17:10.250 --> 17:17.000 User and again users object ID, so you need to grab this somehow and then we have to provide the name 17:17.000 --> 17:18.080 rating and the common. 17:18.080 --> 17:22.970 And again grabbing the user ID shouldn't be a problem at all because only logged in user can give rating. 17:22.970 --> 17:25.910 So we have injected an object request dot user. 17:25.910 --> 17:27.980 So we'll be able to grab name and everything from there. 17:27.980 --> 17:29.450 So shouldn't be a big deal at all. 17:29.870 --> 17:30.140 Okay. 17:30.170 --> 17:32.090 Moving on now. 17:32.090 --> 17:33.230 The next thing is user. 17:33.230 --> 17:35.660 So what is the meaning of this user itself? 17:35.660 --> 17:37.520 So let me go ahead and shrink this review. 17:37.520 --> 17:38.420 It's too big. 17:38.840 --> 17:39.320 Okay. 17:40.010 --> 17:46.550 Now, the idea behind this user is because we might be having so many roles and user at the later point 17:46.550 --> 17:46.910 of time. 17:46.910 --> 17:52.100 Maybe you have a dedicated manager who adds product into your shop, so you want to see who has added 17:52.100 --> 17:52.850 this new product. 17:52.850 --> 17:55.640 So you might want to somebody who is accountable for that. 17:55.640 --> 17:58.700 And that is the only reason why we are adding this user field. 17:58.700 --> 17:59.780 So it's a great revision. 17:59.780 --> 18:03.260 Again, I want to see who is the logged in user who has created this project. 18:03.260 --> 18:05.590 So all I got to do is simply same. 18:05.600 --> 18:07.430 It's going to come up from another document. 18:07.430 --> 18:15.230 So we have to say this is going to be coming from mongoose dot schema, dot object id make sure the 18:15.230 --> 18:16.490 case sensitivity is there. 18:16.490 --> 18:20.330 I also need to provide a ref that hey from where I should reference this one. 18:20.330 --> 18:21.680 So in this case that's the user. 18:21.680 --> 18:22.490 So that's it. 18:22.610 --> 18:24.260 Now again, this is going to be required. 18:24.260 --> 18:27.590 Field So let's go ahead and say, hey, required is going to be true. 18:27.590 --> 18:31.520 I really want to know who has actually came in and added the field. 18:32.000 --> 18:33.650 Okay, what else is remaining? 18:33.650 --> 18:34.220 Just one. 18:34.220 --> 18:35.390 Come on, just one. 18:35.390 --> 18:36.170 We can do it. 18:36.260 --> 18:38.180 This one is going to be created at. 18:38.980 --> 18:40.630 And this one is going to be an object. 18:40.630 --> 18:43.960 This is going to be again, same date we have done it so many times. 18:43.960 --> 18:49.660 Shouldn't be a big deal and the default is going to be date dot now. 18:49.750 --> 18:51.040 Should I write this one? 18:51.190 --> 18:51.730 Yeah. 18:51.850 --> 18:53.410 Great that you have denied. 18:53.410 --> 18:54.820 No, we shouldn't be writing this way. 18:54.820 --> 18:55.840 We should be writing this. 18:55.840 --> 18:57.550 We don't want to execute it right now. 18:57.940 --> 19:03.670 Now, I can go ahead and remove this one now because it's of no use but helped us a lot. 19:05.050 --> 19:09.250 Now we don't really write too many of the methods and inside the mongoose model itself. 19:09.250 --> 19:14.200 But in case you want to go ahead and write more methods as simple something like tokens we have done 19:14.200 --> 19:17.080 in the eight of us, not eight of us in the user. 19:17.200 --> 19:22.460 Like JWT tokens and stuff, we can go ahead and do that, but in this case we won't be needing that. 19:22.480 --> 19:23.730 So quite a long video. 19:23.740 --> 19:25.870 Now, let's go ahead and catch up in the next one.
