Django概览

新学习Django，还不熟练。根据官方文档，总结下常用的操作。

包括：创建project、启动project、创建app

Creating a project

From the command line, cd into a directory where you’d like to store your code, then run the following command:

$ django-admin startproject mysit

This will create a mysite directory in your current directory. If it didn’t work, see Problems running django-admin.

Let’s look at what startproject created:

mysite/
    manage.py
    mysite/ __init__.py settings.py urls.py wsgi.py

The development server

Let’s verify your Django project works. Change into the outer mysite directory, if you haven’t already, and run the following commands:

$ python manage.py runserver

You’ll see the following output on the command line:

Performing system checks...

System check identified no issues (0 silenced).

You have unapplied migrations; your app may not work properly until they are applied.
Run 'python manage.py migrate' to apply them.

Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

Creating the Polls app

To create your app, make sure you’re in the same directory as manage.py and type this command:

$ python manage.py startapp polls

That’ll create a directory polls, which is laid out like this:

polls/
    __init__.py
    admin.py apps.py migrations/ __init__.py models.py tests.py views.py
