WEBVTT 00:01.280 --> 00:01.730 Okay. 00:01.730 --> 00:05.540 In this video we will create a view based on class. 00:05.540 --> 00:10.910 So that will help you understand how the actually actual Django solution works. 00:10.910 --> 00:18.800 So in our view, we have a simple function here, and that's just a function that will return Http response. 00:18.800 --> 00:22.280 So let's try to do something similar with a class. 00:22.280 --> 00:28.340 So I will come here and I will do class here and then I can name it. 00:28.340 --> 00:31.850 I will do an order by by convention. 00:31.850 --> 00:34.610 We start class with a capital letter here. 00:34.790 --> 00:44.510 So we will create a class that will have some functions inside and then we can reference that class 00:44.510 --> 00:45.860 in our. 00:47.340 --> 00:52.110 URLs here, so I will use that class for displaying something. 00:52.110 --> 00:56.790 So we will use something like we use it here, but using the different syntax. 00:57.900 --> 01:00.360 First, we'll need to import views. 01:00.630 --> 01:03.450 So from Django. 01:05.010 --> 01:07.230 Views import? 01:09.310 --> 01:09.730 View. 01:10.210 --> 01:18.400 And then this view will insert inside the parentheses here, which is what we are saying here, is for 01:18.400 --> 01:25.210 that class use whatever is in that view, and then everything will be available for us. 01:25.210 --> 01:33.310 So basically what we can do is we can kind of do similar thing what we've done with our normal function, 01:33.310 --> 01:35.260 but this one will name get. 01:35.680 --> 01:40.810 So we have request as well and then we respond will return something else. 01:40.810 --> 01:47.920 So this is another function inside class. 01:49.620 --> 01:52.710 So we have a different output here. 01:52.710 --> 02:01.260 And basically what we are doing is we are having a get function inside our class so we can do self here. 02:01.290 --> 02:07.080 That means we reference actually this class if we need to use it inside our function. 02:07.080 --> 02:12.210 The first argument here is always a self, which is this class what we have. 02:12.240 --> 02:19.440 So at the moment we have our another class available and let's go to the URLs and we'll just duplicate 02:19.440 --> 02:20.280 this line. 02:20.280 --> 02:21.840 We'll put a comma on this one. 02:21.840 --> 02:30.360 So it will be a array of different paths so I can do another, which is just a name for URL. 02:30.360 --> 02:35.490 And then here what I can do is I can do another. 02:36.090 --> 02:39.000 Actually I need to go, I will import that. 02:39.030 --> 02:40.080 So from. 02:41.640 --> 02:44.910 Dot views, import and other. 02:44.910 --> 02:51.750 So we'll just import that class from the file views and then I can use this another reference that another 02:51.750 --> 02:53.880 and then I can do as view. 02:54.510 --> 02:58.770 So treat this class as a view if I will save it. 02:58.770 --> 03:02.550 Now I think we have indentation problem. 03:04.420 --> 03:09.040 And Python is just very picky. 03:10.210 --> 03:14.050 So we need to have indentation here and two indentations here. 03:14.050 --> 03:17.230 I will save it and then I will run it again. 03:19.250 --> 03:20.270 And let's try it. 03:20.750 --> 03:24.260 Let's try our new URL, which is another. 03:26.750 --> 03:31.040 I can do that with first function and then I will try another. 03:31.040 --> 03:35.000 And you can see here, this is another function inside class. 03:35.360 --> 03:37.490 So I can go here. 03:37.490 --> 03:42.380 I will make it a little bit bigger for you to see the URL. 03:44.130 --> 03:51.460 So what we have here is the another is pointing to our class that we've created inside views. 03:51.480 --> 03:58.170 So views is a class and then we have a method get and that will response this text, which is this one. 03:58.170 --> 04:02.100 We still can use this normal function as we did before. 04:02.100 --> 04:05.070 So both of these will be available. 04:05.070 --> 04:11.520 So first and another, let's try first you can see first message from The View. 04:11.550 --> 04:13.530 This is first message from The View. 04:13.530 --> 04:16.380 So we have two different options to use. 04:16.380 --> 04:19.560 We can use normal function or we can use class. 04:19.590 --> 04:27.480 Class is more complex option and you need to write a little bit of more syntax to have it, but it will 04:27.480 --> 04:30.630 give us much more flexibility. 04:30.660 --> 04:36.450 Basically, in that view, what we have is we already have a lot of things included. 04:36.450 --> 04:44.800 So if I will hold command or on my keyboard and click on The View, you can see here we already have 04:44.800 --> 04:49.780 different methods available for us and then we have other things here. 04:49.780 --> 04:58.120 I don't recommend reading this if you are not a really experienced Python developer and you know a little 04:58.120 --> 05:04.030 bit of Django, but this is actually what we include in our class. 05:04.030 --> 05:12.130 So we we are telling Django or telling Python that include whatever is available on this class which 05:12.130 --> 05:15.310 is the built in Django views inside our class. 05:15.310 --> 05:22.150 So everything is available like the method gets or like the method as view as we have here. 05:22.150 --> 05:27.510 So later on I will show you what's actually included in the classes. 05:27.510 --> 05:36.970 So we'll use model view class, which is has more functionality built in, but basically that's how 05:36.970 --> 05:37.930 we do it. 05:37.960 --> 05:45.820 We might have on the classes more options so we can decide we can have some attributes here and some 05:45.820 --> 05:54.040 other functions and we, we can reference this all options and we can also reference the class itself. 05:54.130 --> 06:03.580 So that's how we can write views with classes and we will extend that knowledge later on for having 06:03.580 --> 06:05.230 full Django solution.
