django 中新建auth_user_model

     在项目中不想使用django自带的用户管理系统，需要增加一些用户属性，我们可以这么做。

     在app的model.py 中继承AbstractUser创建自己的用户管理系统类 user_info

from django.contrib.auth.models import AbstractUser

class user_info(AbstractUser):
   author = models.CharField(max_length=12)
   login = models.BooleanField(default=False)

   def __str__(self):
      return self.username

         之后使用命令python manage.py makemigrations创建数据库表，碰到如下错误。

root@startbudd2:/home/zhj/lot/star_lot# python manage.py makemigrations
SystemCheckError: System check identified some issues:

       解决这个问题的方法：

       在本工程的setting.py 文件中添加：      

  AUTH_USER_MODEL = "star_link.user_info"
