Django迁移数据库时报错：auth.User.groups: (fields.E304) Reverse accessor 'Group.user_set' for 'auth.User.groups' clashes with reverse accessor for 'userSystem.UserInfo.groups'.等信息

报错如上图

原因：当自定义user模型并继承AbstractBaseUser时，会报这样的错误。当创建Django项目是，程序会自动创建一个user模型。这时我们自定义一个user模型后如果不在setting配置文件更改用户模型，迁移程序不知道使用哪个用户模型，最终报错：

    SystemCheckError: System check identified some issues:

解决办法： 在setting.py文件中添加配置 AUTH_USER_MODEL = 'app.数据库用户模型'
