By specifying an IP address, you can tell the server – Allow non-local connection access. This feature is especially useful if you want to share the same development site with other developers. The ' 0.0.0.0 ' IP address tells the server to listen on any network interface.

Python manage.py runserver 0.0.0.0:8000 The above is the Django server running at CMD Terminal next to run on the server side on Pycharm:If you run the manage.py program directly, you will be prompted with a lot of things, that is, the hint is not passed parameters.

Let's take a look at some of the necessary concepts first. What does Django call an APP?

We've created project, so what's the difference between project and APP? The difference is that one is to configure the other is the code:

A project contains a number of Django apps and their configuration.

Technically, project's role is to provide configuration files, such as where to define database connection information, the list of installed apps, Template_dirs, and so on.

An app is a set of Django features, often including models and views, in the way Python's package structure exists.

For example, Django itself has some apps, such as a comment system and an automated management interface. One key point of the app is that they are easily ported to other project and reused by multiple project.

Create an App

Under the "Pythonproject" project file, enter the following command to create the "Nowamagic" app:

1	python manage.py startapp nowamagic

This command does not output anything, it only creates a nowamagic directory in the Pythonproject directory. Let's take a look at the contents of this directory:

1	nowamagic/

2	__init__.py

3

models.py

4

tests.py

5

views.py

This directory contains the model and view of the app.

Use your favorite text editor to see the contents of the models.py and views.py files. They are all empty except for an import in the models.py. This is the foundation of your Django app.

• There are no quick sets of rules for how to structure Django code. If you're just building a simple Web site, you probably just need an app, but if it's a complex site with many unrelated modules, such as e-commerce and community sites, you might want to divide the modules into different apps for later reuse.

Yes, you don't have to create apps, which should be proven by examples of view functions we've written before. In those cases, we simply created a file called views.py, wrote some functions, and set the mappings for each function in the urlconf. These situations do not require the use of apps.

However, the system has a convention for apps: If you use a Django database layer (model), you must create a Django app. The model must be stored in the apps. So, in order to start building our model, we have to create a new app.

You'll find out later how much convenience the app will bring to us.
