In this tutorial, we’re going to take a look on each file that exists in our django project folder.

在本教程中，我们将研究django项目文件夹中存在的每个文件。

Let’s say, we’ve created a project named as **my\_website** on our desktop. Now open that folder you can see another folder (directory) with the same name inside our project folder.

假设我们已经在桌面上创建了一个名为**my\_website**的项目。 现在打开该文件夹，您可以在我们的项目文件夹中看到另一个具有相同名称的文件夹(目录)。

![Django Project Tour 1][]

Along with this directory, we’ve other two files **db.sqllite3** and **manage.py.**

除了这个目录，我们还有另外两个文件**db.sqllite3**和**manage.py。**

Let’s understand these files.

让我们了解这些文件。

### manage.py **(**manage.py**)** ###

This is the file that we’ve used to run server. Basically that manage.py file help us to do some top level admin things. To see all the funtionality of that file other than running a server, just open terminal or command prompt and navigate to the directory where our manage.py file exists and run the command below.

这是我们用来运行服务器的文件。 基本上，manage.py文件可以帮助我们执行一些高级管理操作。 要查看除运行服务器以外该文件的所有功能，只需打开终端或命令提示符，然后导航到manage.py文件所在的目录，然后运行以下命令。

***python3 manage.py help***

***python3 manage.py帮助***

要么

***python manage.py help**  (*if you have only python3 installed in your system*)*

***python manage.py帮助** (*如果您的系统中仅安装了python3 *)*

Now after running this command you can actually see all the things that our manage.py file can do like **startapp, runserver, collectstatic.** We’ll use many of these things later and we should never edit this file if you’re editing this file for specific reason, at that point you should be an expert django user before you go messing up with this file.

现在，运行此命令后，您实际上可以看到我们的manage.py文件可以执行的所有操作，例如**startapp，runserver和collectstatic。** 我们稍后将使用其中的许多功能，并且如果出于特定原因要编辑此文件，则永远不要编辑此文件，这时您应该成为django的专业用户，然后再弄乱该文件。

### db.sqlite3 **(**db.sqlite3**)** ###

This file is a database that is generated for us whenever we make a new project and run the server. This is going to be a non-human readable file. It’s supposed to store data in a really efficient way.

该文件是一个在我们创建新项目并运行服务器时为我们生成的数据库。 这将是一个非人类可读的文件。 应该以一种非常有效的方式存储数据。

Now open my\_website directory inside our project folder and you’ll see some other files and a directory as shown below.

现在打开项目文件夹中的my\_website目录，您将看到其他文件和目录，如下所示。

![Django Project Tour 2][]

### \_\_pycache\_ **(**\_\_pycache\_**)** ###

This directory is going to be auto-generated everytime when we’re running the server. Inside \_\_pycache\_ there are some other files having extension **.pyc.** These are some internal files, we doesn’t need to worry about these at all.

每当我们运行服务器时，都会自动生成此目录。 在\_\_pycache\_内部，还有一些扩展名为**.pyc的**文件**。** 这些是一些内部文件，我们完全不需要担心这些。

### \_\_init\_\_.py **(**\_\_init\_\_.py**)** ###

This is also created automatically whenever we initially create a new project and we’ll never touch this file too because this file is not there for programmer’s use. It is there for some internal django working. We’re not going to worry about it too.

每当我们最初创建一个新项目时，它也会自动创建，并且我们永远也不会触摸此文件，因为该文件不存在供程序员使用。 它在那里有一些内部Django工作。 我们也不会为此担心。

### settings.py **(**settings.py**)** ###

This is the file, that we’re going to use a lot. If we open this file using any text editor then you can see that there is a **BASE\_DIR** variable that have the path of our base directory of our project.

这是文件，我们将大量使用。 如果我们使用任何文本编辑器打开此文件，则可以看到存在一个**BASE\_DIR**变量，该变量具有项目基本目录的路径。

![Django Project Tour 3][]

Next there is a **SECRET\_KEY** that we should never show to anybody if we’re going to pushing up our project to internet. We can also change this key as we want to.

接下来是一个**SECRET\_KEY** ，如果我们要将项目推向互联网，我们绝对不应该向任何人展示。 我们还可以根据需要更改此密钥。

![Django Project Tour 4][]

Next is **DEBUG**, that is set as True. This is basically saying that you are working in a development environment on your computer. This helps us to show errors while running our project. When our project will be live on the internet, we’ll set DEBUG as False.

接下来是**DEBUG** ，将其设置为True。 基本上是说您正在计算机上的开发环境中工作。 这有助于我们在运行项目时显示错误。 当我们的项目将在互联网上发布时，我们将DEBUG设置为False。

Next two variables are **ALLOWED\_HOSTS** and **INSTALLED\_APPS** that we’ll see later when our project will be under production phase.

接下来的两个变量是**ALLOWED\_HOSTS**和**INSTALLED\_APPS** ，我们稍后将在项目**进入**生产阶段时看到。

Next is **MIDDLEWARE**, This is also some advance stuff and auto-generated code by django.

接下来是**MIDDLEWARE** ，这也是django的一些高级知识和自动生成的代码。

![Django Project Tour 5][]

Then there is a **ROOT\_URLCONF** variable that’s basically saying where your initial URL file is.

然后有一个**ROOT\_URLCONF**变量，它基本上是在说您的初始URL文件在哪里。

![Django Project Tour 6][]

Next one is **TEMPELATES**, basically these tempelates helps to turning the python code into HTML, because when someone requests a website, it is going to give back HTML. As we can see when we open page source of any webpage, It gives us bunch of HTML Tags.

下一个是**TEMPELATES** ，基本上这些模板将有助于将python代码转换为HTML，因为当有人请求一个网站时，它将返回HTML。 正如我们看到的，当打开任何网页的页面源代码时，它为我们提供了一堆HTML标签。

![Django Project Tour 7][]

Next is **WSGI\_APPLICATION**, This is used when we’re hosting our project live, how people connect with it. We’ll see more when we publish our project live to the internet.

接下来是**WSGI\_APPLICATION** ，当我们实时托管我们的项目时人们会用到它。 当我们将项目实时发布到互联网上时，我们会看到更多。

![Django Project Tour 8][]

Next is **DATABASES**, This is the code that generated that file named as **db.sqlite3** in our project directory. If we want to create another database file then we can also generate by editing this code.

接下来是**DATABASES** ，这是在我们的项目目录中生成名为**db.sqlite3的**文件的代码。 如果要创建另一个数据库文件，则还可以通过编辑此代码来生成。

![Django Project Tour 9][]

Next is **AUTH\_PASSWORD\_VALIDATORS**, This basically saying that whenever someone makes a new user account what sort of things do we want to require of to get their passwords we’ll see it later too.

接下来是**AUTH\_PASSWORD\_VALIDATORS** ，这基本上是说，只要有人注册一个新用户帐户，我们需要什么样的东西才能获取密码，我们稍后也会看到。

![Django Project Tour 10][]

Now other variables like **LANGUAGE\_CODE**, **TIME\_ZONE** are just there for making our website unique like what language code we want to use, by default it is US-English and what Time-zone we want to use.

现在，还有其他变量，例如**LANGUAGE\_CODE** ， **TIME\_ZONE** ，用于使我们的网站具有独特性，例如我们要使用的语言代码，默认情况下是美国英语，以及我们要使用的时区。

### urls.py **(**urls.py**)** ###

Anytime someone visits our website that is s connected to our django project. It’s going to come into this file and this file decides where the user’s requests should go next and what HTML is to sent back to user.

每当有人访问连接到django项目的我们的网站时。 该文件将进入该文件，该文件决定了下一步应将用户的请求发送到哪里以及将什么HTML发送回给用户。

![Django Project Tour 11][]

### wsgi.py **(**wsgi.py**)** ###

This file is for hosting our website so other people can access it, we’ll see this file when we upload our project to a server.

该文件用于托管我们的网站，以便其他人可以访问它，将项目上载到服务器时，我们会看到此文件。

![Django Project Tour 12][]

So I hope you have understood that what the files inside our project folder are and what are the uses of those files.

因此，我希望您了解我们的项目文件夹中的文件是什么以及这些文件的用途。
