WEBVTT 00:01.660 --> 00:07.030 Okay, we have our application running and we have our project. 00:07.030 --> 00:14.770 But project is like a container for our applications and we might have more than one application inside. 00:14.770 --> 00:16.990 So what is actually application? 00:17.020 --> 00:23.530 Application will be part of your code of your project that will do a certain thing. 00:23.530 --> 00:30.550 So for example, you might have a project that will contain our do a lot of things, but application 00:30.550 --> 00:34.210 will have the single responsibility. 00:34.210 --> 00:37.690 So you can have multiple applications, you might have one. 00:37.690 --> 00:41.020 All depends on your architecture and your design. 00:41.020 --> 00:47.110 In this tutorial, we'll focus on only one application because that will be easier to maintain, but 00:47.110 --> 00:48.760 you don't need to keep it as one. 00:48.760 --> 00:54.280 You might have more than one and then you can communicate in between the application as you wish. 00:54.430 --> 01:01.030 So at the moment we don't have any application, so our Django project is kind of not usable. 01:01.030 --> 01:02.510 So let's create one. 01:02.510 --> 01:08.570 So how we can actually create one, I will go to terminal and in the same way as use, I use terminal 01:08.570 --> 01:10.820 in my IDE on my system. 01:10.820 --> 01:12.200 I can use it here. 01:12.200 --> 01:15.710 So I'm inside the tutorial folder which is here. 01:15.710 --> 01:18.440 What I can do is I have two choices. 01:18.440 --> 01:27.110 I can use a python manage.py this file as we use before or I can do admin Django admin the same way 01:27.120 --> 01:29.510 I've I've created a Django project. 01:29.510 --> 01:31.220 So one way will be Django. 01:32.940 --> 01:39.480 Admin and then start up and then name of the app. 01:39.480 --> 01:46.140 And I will I can create an app called demo so I can do it like this. 01:46.140 --> 01:55.560 Or instead of Django admin I can do python manage.py start up demo the same way I will use this one 01:55.560 --> 02:02.010 and if we'll go here you can see demo has been created here and we have two folders. 02:02.010 --> 02:07.650 So we have one demo here which is our application and this is our project. 02:07.860 --> 02:15.090 So some people prefer to have this demo or this application inside our folder. 02:15.090 --> 02:16.530 It's really up to you. 02:16.560 --> 02:18.330 How would you like to have it? 02:18.330 --> 02:26.280 But if that's up our application, it might be better to put this inside it or outside it. 02:26.310 --> 02:34.020 I will keep it as as it is here because it doesn't really matter that much at And then the only thing 02:34.360 --> 02:40.090 what you will need to do is you will need to have a reference, but you need to remember this is project 02:40.090 --> 02:42.070 and this is our application. 02:42.070 --> 02:48.190 So actually let's close this for now and see what we have in our files. 02:48.700 --> 02:50.770 Let's start from the root directory. 02:50.770 --> 02:52.990 Here we have our manage.py. 02:53.020 --> 03:00.040 If we open this file, basically it's not something that we will be interested in, but this file is 03:00.040 --> 03:05.410 for us to run our commands for our Django so we can forget about the content of this. 03:05.410 --> 03:09.880 But it is very useful file to to manage our Django. 03:10.420 --> 03:17.950 Another file we have in the root folder is database Sqlite3 that has been created for us automatically 03:17.950 --> 03:18.760 by Django. 03:18.760 --> 03:20.740 And this is local database. 03:20.740 --> 03:25.570 So whatever we will store in our application, any data will go here. 03:25.570 --> 03:28.840 That's not a proper solution for production environment. 03:28.840 --> 03:35.740 So if you put your application on a server, you should not use SQLite because this is more like a testing 03:35.740 --> 03:37.540 environment database. 03:37.960 --> 03:40.090 So it's very easy to set up. 03:40.090 --> 03:46.930 This is a normal file and you can write things into the sqlite3, but if you would like to have something 03:46.930 --> 03:51.910 fast and reliable, the option will be MySQL or Postgres database. 03:51.910 --> 03:58.000 But for now we can use this one because we are not testing that application on server yet. 03:58.270 --> 04:01.090 So what else we have to implement? 04:01.120 --> 04:08.290 We already talked about this, so we have our project here and inside the project we have few files. 04:08.320 --> 04:12.340 First we have URLs and then we have settings. 04:12.340 --> 04:17.980 The rest of the files are not really something that we will ever change, so we have some in it. 04:18.010 --> 04:24.520 This is for initiate our project and then we have a wsgi which is more like a configuration for our 04:24.520 --> 04:25.150 server. 04:25.150 --> 04:29.710 So let's see what's inside the URLs, inside URLs. 04:29.740 --> 04:34.120 As you can see here, we don't have a support for for Django, but it doesn't really matter. 04:34.120 --> 04:35.410 We can close this. 04:35.410 --> 04:41.050 So in here you have in the comment section, you have some explanation how to use the URLs. 04:41.050 --> 04:47.500 But basically what this file is doing is it will give us some kind of paths. 04:47.500 --> 04:53.440 So if we go to our application here, that's a URL we are using. 04:53.440 --> 05:00.640 But if you take a look here, we have another patch that is available, which is admin. 05:00.640 --> 05:07.150 So basically if I will type admin at the very end admin, I have another page here. 05:07.150 --> 05:10.060 We'll talk about this later in the course. 05:10.060 --> 05:15.640 But this URLs basically kind of do mapping for our application. 05:15.640 --> 05:20.890 So whatever we will have here, it will be available as a URL in our application. 05:20.890 --> 05:27.430 So at the moment built in we have admin, but we will create more our own later in the tutorial. 05:27.430 --> 05:29.020 So this is URLs. 05:29.020 --> 05:31.570 I can open another file which is settings. 05:31.570 --> 05:35.650 This settings it's all settings for for our project. 05:35.650 --> 05:40.120 So we will be talking more about this and we will change a lot of things here. 05:40.120 --> 05:46.360 But basically if you would like to change something in your application, you will need to do it here 05:46.360 --> 05:48.430 inside the settings page. 05:48.430 --> 05:51.400 So we have a templates database. 05:51.400 --> 05:59.770 You can see here Django Database Sqlite3 is the one we use, and this name of the file is exactly this 05:59.770 --> 06:00.490 name here. 06:00.490 --> 06:06.040 So if you would like to switch to another database, you will need to go to the settings and change 06:06.040 --> 06:09.100 it here and you have other options here. 06:09.100 --> 06:15.970 But as I said, we'll come back to this many different times and we'll add and change things on the 06:15.970 --> 06:16.330 settings. 06:16.330 --> 06:19.330 So basically the settings control our project. 06:20.110 --> 06:22.900 So that's our project. 06:23.080 --> 06:26.560 I will close both of this and I will go to the demo. 06:27.070 --> 06:32.110 In demo we have a few things and we will be talking more about these files. 06:32.220 --> 06:39.930 Later in the tutorial, but important files for us will be the models which is empty at the moment will 06:39.930 --> 06:40.740 be views. 06:41.370 --> 06:43.590 It's also empty at the moment. 06:43.590 --> 06:48.990 And also we'll have some other files here that we will create. 06:48.990 --> 06:54.630 But the models basically represent our objects in database, whatever. 06:54.630 --> 07:01.170 We would like to store something in database, we'll need to create a model here and then we will apply 07:01.170 --> 07:06.000 it for our database using a migrations command. 07:06.000 --> 07:10.500 And then we have also views and views will be kind of our endpoint. 07:10.500 --> 07:16.410 So if we would like to access part of our application, we'll use views to do that, but we'll be doing 07:16.410 --> 07:18.990 a lot of different things in our views and models. 07:18.990 --> 07:25.830 And also I will show you how to create another view files and how we can structure our application.
