WEBVTT 00:01.620 --> 00:02.340 Okay. 00:02.370 --> 00:07.470 In this video, I will show you how to see what's inside our database. 00:07.470 --> 00:12.260 And for this we'll use built in Django admin view. 00:12.270 --> 00:23.550 So if we go to our chrome, this is our admin view and the URL for this is this 127 001 which is localhost 00:23.550 --> 00:26.610 and then 8000 port and then slash admin. 00:26.610 --> 00:29.940 And you can see here it's a login page. 00:30.030 --> 00:37.140 At the moment we don't have any credentials and we can't, can't login in the Django administration 00:37.140 --> 00:37.680 here. 00:37.680 --> 00:44.190 The reason for this is we don't have a user in our system and we'll create a user on our system. 00:44.190 --> 00:49.740 I will show you how to do it and then how we can actually access this and manage Django administration. 00:49.980 --> 00:50.340 Okay. 00:50.340 --> 00:54.000 So let's go back to our IDE and let's create a user. 00:55.080 --> 01:01.720 So we are inside our terminal in IDE and I can run command in a similar way. 01:01.720 --> 01:02.740 We run it before. 01:02.740 --> 01:03.910 So Python. 01:04.910 --> 01:09.680 Three or just python if you have one installed on your machine. 01:09.890 --> 01:15.530 Manage pi and then create super user. 01:15.840 --> 01:18.050 Altogether create super user. 01:18.050 --> 01:20.210 And then we click enter. 01:20.840 --> 01:27.830 And then we have some message here about three unapplied migrations and the admin and out. 01:27.830 --> 01:32.330 And then they ask us to run the command python manage.py migrate. 01:32.360 --> 01:35.560 We already did it so we'll kind of ignore it for now. 01:35.570 --> 01:43.820 So basically this so actually might not have this displayed, but running this command, it will ask 01:43.850 --> 01:45.170 us for a few things. 01:45.170 --> 01:48.680 So basically first thing will be the username. 01:48.680 --> 01:55.880 If you will leave it blank, it will be the same user as you have on your machine and I have a user 01:55.880 --> 02:00.350 Christian, so I will leave it blank and I will click enter and then we have email address. 02:00.350 --> 02:04.890 You don't need to type anything here, but if you like you can put your email address. 02:04.890 --> 02:08.580 I will click Enter and then we need to set up a password. 02:08.610 --> 02:18.870 I will set a password like my username Christian and then Christian and it's too similar to the username, 02:18.870 --> 02:21.930 so I'll actually should create a different one. 02:22.260 --> 02:26.400 But for our tutorial needs I can leave it as it is. 02:26.580 --> 02:32.400 And because we are not really concerned about the security, but please don't put an application with 02:32.400 --> 02:38.010 the same username and password on the production server because you will put your application at risk. 02:38.010 --> 02:41.690 But we can bypass password validation and create user anyway. 02:41.700 --> 02:44.310 I can click yes and then enter. 02:44.310 --> 02:51.660 So we have created super user and we have that user with a username Christian and password Christian 02:51.690 --> 02:53.220 available for us to use. 02:53.220 --> 02:57.030 So that's been added to our database and that's an admin user. 02:57.030 --> 02:59.010 So if I'll come back to the chrome. 03:00.530 --> 03:01.610 We can see here. 03:01.610 --> 03:08.480 Username is Christian and the password will be Christian the same way I've done it just a second ago 03:08.480 --> 03:13.130 and I will log in here and I'm inside the Django administration. 03:13.130 --> 03:16.580 So basically this screen allows me to see everything. 03:16.580 --> 03:19.040 What's inside that database. 03:19.130 --> 03:22.490 As soon I will add it to the Django administration. 03:22.700 --> 03:25.910 And you can see here you have authentication and authorization. 03:25.910 --> 03:30.260 If I go to the users, you can see my user here. 03:30.260 --> 03:38.450 So I have a user and that's all information about my user I've created with create super user a command. 03:38.450 --> 03:46.700 So I have groups and users available and I can add new users here, I can change and I can do a lot 03:46.700 --> 03:56.210 of things here in that provided user interface, but we don't see our model the way that. 03:58.820 --> 04:03.950 The model we have created here book is at the moment not available in the admin. 04:03.950 --> 04:09.830 And the reason for this is we will need to add it manually to our admin file. 04:09.830 --> 04:14.330 So let's open admin and you can register your models here. 04:15.170 --> 04:22.190 So let's remove this and we can do admin side. 04:25.000 --> 04:33.510 Register and then we can put the same name here, which is book. 04:33.520 --> 04:36.490 So I will register here a book. 04:36.490 --> 04:38.380 But at the moment it's underlined. 04:38.410 --> 04:41.800 That means it's unresolved reference. 04:41.800 --> 04:44.350 So we need to import so from. 04:46.320 --> 04:46.860 Models. 04:48.580 --> 04:49.750 That's in the same folder. 04:49.750 --> 04:53.260 So dot models import book. 04:53.560 --> 05:00.560 Once we import book, the red line is gone and then we do admin site register our model. 05:00.580 --> 05:02.200 So if I will save it now. 05:06.400 --> 05:08.950 And then we'll refresh the server. 05:10.120 --> 05:14.470 I will go to the this view and I will refresh the page. 05:15.310 --> 05:17.110 And you can see here the demo. 05:17.140 --> 05:19.300 This is the name of our application. 05:19.300 --> 05:23.800 And then inside the demo we have one model, one model called books. 05:23.800 --> 05:31.540 And if I will go to the books, there is a zero books inside our database, but I can add book here 05:31.660 --> 05:38.980 and you can see here title is this field we specified in our models. 05:38.980 --> 05:44.710 So we have title and that's a char field maximum 36 character long. 05:44.740 --> 05:49.570 And this user interface represents this setup from the file. 05:49.570 --> 05:51.700 So we have a book with a title. 05:51.700 --> 06:04.300 Let's add a book here and I will add for example, Hobbit, I can do Save, and this represents a new 06:04.300 --> 06:06.020 record in our database. 06:06.020 --> 06:13.850 I can click on this and I can see here I can change it so I can change anything here and then save it. 06:13.880 --> 06:18.290 I can remove it from database or I can add more into it. 06:18.290 --> 06:22.310 So this user interface allows us to manage our database. 06:22.310 --> 06:27.140 So whatever you need to do on your database level, you can do it directly from here. 06:27.140 --> 06:33.710 So sometimes the Django application for Django application, the Django administration user interface 06:33.710 --> 06:40.190 will be enough for a application because if you want to store a simple records in the database and you 06:40.190 --> 06:44.900 need a simple user interface, you can use Django administration for that. 06:44.900 --> 06:50.990 You can log in with your super user and then you can add records, remove records and manage all records 06:50.990 --> 06:52.190 in one place. 06:52.460 --> 06:59.360 So in this video, I will show you how to use the Django administration and how to create a super user.
