WEBVTT 00:01.240 --> 00:02.410 In this video. 00:02.410 --> 00:10.690 We'll come back to our admin page and I will show you how we can actually use built in admin and extend 00:10.690 --> 00:11.870 it for our needs. 00:11.880 --> 00:20.560 So I will open admin and you can see here we have our model registered here and I will show you another 00:20.560 --> 00:27.550 way how we can actually register our models that will give us much more control over what we would like 00:27.550 --> 00:29.950 to see and how we would like to see it. 00:29.950 --> 00:33.370 So first, let's come back to our admin page here. 00:33.370 --> 00:35.950 So instead of demo first I will go admin. 00:37.590 --> 00:38.910 And I can see we are here. 00:38.910 --> 00:42.150 So we'll go to the books and this is what we see. 00:42.890 --> 00:50.960 So first thing, what I would like to do is instead of tag book object here, this is not really human 00:50.960 --> 00:51.710 readable. 00:51.710 --> 00:53.570 We can handle this. 00:53.600 --> 00:58.460 And the way we handle this is going to our models. 00:58.790 --> 01:04.330 We have our book here, so that's a list of fields we have available. 01:04.340 --> 01:11.840 But also we can specify how our class will be converted to string. 01:11.870 --> 01:18.440 At the moment, Django doesn't really know how to do our book, how to convert it to string to read 01:18.440 --> 01:18.560 it. 01:18.560 --> 01:22.490 So it's a book object for him and that's the best he can do. 01:22.490 --> 01:25.940 But we can actually use our own method to do that. 01:25.970 --> 01:33.380 We can do def and then underscore, underscore, str like string, underscore, underscore and you can 01:33.380 --> 01:37.970 see rest of it is we can actually click enter and it will be like that. 01:37.970 --> 01:45.750 So definition and then underscore, underscore str, underscore, underscore and then self to refer 01:45.750 --> 01:52.410 to our class and in here we can return, return, whatever we like. 01:52.440 --> 01:56.970 In our case, what will be the good data to display for a book? 01:57.000 --> 01:58.170 Obviously title. 01:58.170 --> 01:59.820 So what I can do is self. 02:01.310 --> 02:10.970 The title and we are telling that every time we would like to see our book displayed as a string, let's 02:10.970 --> 02:12.950 use title for it. 02:12.980 --> 02:20.750 If I will save it now and I come back here and refresh it, you can see instead of that object now we 02:20.750 --> 02:21.770 can see title. 02:21.770 --> 02:24.500 So that's one thing that we've changed. 02:24.530 --> 02:30.980 So let's go to the one of those and you can see we have that kind of fields here. 02:30.980 --> 02:38.210 If we come back to our admin page, we can actually change it and control what we see. 02:38.420 --> 02:45.590 This is very generic admin site register book, but I will show you another way we can actually deal 02:45.590 --> 02:50.900 with that and register our book with some more greater control. 02:50.930 --> 03:00.870 So what we can do is we will use decorator, admin dot register and then we can register our book here 03:00.870 --> 03:01.830 like that. 03:01.830 --> 03:05.490 And then what we need to do is we need to create a class. 03:05.490 --> 03:13.140 So we will do book admin, we can name it whatever we like, but book admin, it's a good convention. 03:13.140 --> 03:17.430 The first part is our model and then admin here. 03:18.240 --> 03:25.830 And then inside we will pass admin model, admin like that. 03:25.830 --> 03:34.680 And then we basically what's what this is doing is we still register our book and then we will use it 03:34.680 --> 03:38.550 in the class and then we have some extra options. 03:38.550 --> 03:39.710 I will show you a few. 03:39.720 --> 03:42.330 So first we can specify the fields. 03:42.330 --> 03:52.230 So let's say I would like to show title as a field available if I will save it now and come back here. 03:52.230 --> 03:54.650 And that was what did. 03:54.660 --> 03:56.370 This is what it was before. 03:56.400 --> 04:01.080 If we refresh it now, you can see only title is displayed. 04:01.080 --> 04:07.860 The reason for this is because we decided that title is the only option we should display. 04:07.860 --> 04:17.460 So if I will add another one, like for example, description here, save it, we'll come back here, 04:17.460 --> 04:18.240 refresh it. 04:18.270 --> 04:21.540 You can see title and description is displayed. 04:21.540 --> 04:30.660 So if you don't need some of the fields to be displayed in the UI, then you can hide it or you can 04:30.660 --> 04:36.810 decide which one you would like to include in your in your UI. 04:37.350 --> 04:46.740 Another thing we can do is list display and then let's say we can display title and description. 04:47.730 --> 04:53.280 And for now, I will remove these fields and we'll revert it back to how it was. 04:53.280 --> 04:55.680 But this time we'll use a list display. 04:56.490 --> 04:57.750 So we can keep the boat. 04:58.170 --> 05:03.720 You don't need to have one or another, but I will remove it just for easier. 05:03.720 --> 05:06.720 So I will refresh it and you can see all of it. 05:06.720 --> 05:09.810 It's back because the fields, we don't have anything in the fields. 05:09.810 --> 05:16.980 But if I will come back to the books, you can see here we have a table, the table with a title and 05:16.980 --> 05:17.820 description. 05:17.820 --> 05:20.880 So now the title is here and description is here. 05:20.880 --> 05:28.470 If you would like to have something else displayed in this view, you can specify this here. 05:28.470 --> 05:32.730 So let's say price is something you would like to have in that view. 05:33.660 --> 05:36.000 Come back here, refresh. 05:38.530 --> 05:40.960 I haven't saved, I think, this file. 05:48.500 --> 05:49.280 Refresh. 05:49.280 --> 05:53.690 And you can see a lot of this is a title and this is a price. 05:55.520 --> 05:57.890 So what else is available? 05:58.580 --> 06:10.100 We can do list filter, list, filter, for example, and then we can decide on which one we will filter. 06:10.100 --> 06:12.740 Let's say we can filter by published. 06:13.460 --> 06:15.410 So I will put it here. 06:15.830 --> 06:19.640 I will save that and come back here and then I will refresh it. 06:19.670 --> 06:27.020 You can see new filter has been added to our admin page and we have some filters here. 06:27.020 --> 06:32.150 This depends on the type of the field that we are filtering. 06:32.150 --> 06:34.280 We are filtering by date. 06:34.280 --> 06:40.910 So this is common to like this month past seven days, seven days today and so on and so on. 06:41.330 --> 06:48.960 So this is the the filter and we you can pass more than one filter to it so we can pass it as many as 06:48.960 --> 06:53.190 you like and you will have that handy pane for filtering. 06:54.060 --> 07:05.490 Another option will be search fields so we can have a search in the same page. 07:05.490 --> 07:08.070 And let's say we would like to search by title. 07:08.670 --> 07:15.030 I will save it here and come back to our admin, refresh it and you can see on the top of the page we 07:15.030 --> 07:23.850 have Search Hobbit and then I will click search and you can see only Hobbit is displayed here because 07:23.850 --> 07:26.270 I searched for this if I. 07:27.770 --> 07:29.210 I specify here. 07:29.210 --> 07:31.730 More fields. 07:31.760 --> 07:33.440 Description. 07:33.470 --> 07:42.590 For example, the search will go for title and description and the return result will be matching that 07:42.590 --> 07:43.040 record. 07:43.040 --> 07:45.020 So title and description. 07:45.020 --> 07:48.410 We don't have much in the description, so this is not going to work. 07:48.410 --> 07:58.010 But in in fact this two totals, this is without search and then I can filter or find my records in 07:58.010 --> 07:59.420 database using this. 07:59.450 --> 08:06.920 As you can see, this page start to be very user friendly and that might be your entire application. 08:07.190 --> 08:14.720 What I mean by application some sometimes you you need to have something to store records in the database. 08:14.720 --> 08:20.870 You need to have some kind of view user interface and login and you have all that built in Django. 08:20.900 --> 08:28.950 So if you need that simple things, you can do user authentication and then you can provide them an 08:28.950 --> 08:35.250 optimize views to manage the the resources on the database. 08:35.250 --> 08:39.660 As you can see, you can use filters, you can decide what you include in this list. 08:39.660 --> 08:45.210 You can have a custom search and also you can decide what they will be able to edit here. 08:45.210 --> 08:46.800 So that's pretty much it. 08:46.800 --> 08:50.070 That's how Django administration works. 08:50.070 --> 08:56.220 There is much more than I will show you, but I've showed you the basic one, the most important part. 08:56.220 --> 09:02.790 But you can also go to a official Django documentation to see what the what the other options are. 09:02.820 --> 09:08.430 But as you can see, this is very powerful view and give it to us for free.
