Three: Hands
1. Create a project
Creating (1) command line
django-admin startproject MxOnline
(2) use to create pycharm
2.创建应用
在pycharm打开终端，依次输入以下命令，创建四个APP
python manage.py startapp users
python manage.py startapp course
python manage.py startapp organization
python manage.py startapp operation
3.编写model代码
（1）users 用户
由于Django有自己的一套认证权限系统，当然包括user表了，所以我们只需要在其基础上增加功能即可。
系统自动生成的user表字段如下：
id:主键
password:密码
is_superuser：是否为超级用户（后台管理）
username 用户名字段不要随便改动
email 邮箱
is_staff 表示是否是员工(后台管理)
is_active 用户是否是激活状态
date_joined 注册时间
所以我们只需要继承AbstractUser类
