User model

自定义 User Model（扩展 AbstractUser类）
如果你对django自带的User model刚到满意, 又希望额外的field的话, 你可以扩展AbstractUser类:

from django.contrib.auth.models import AbstractUser

class UserInfo(AbstractUser):
    """
    用户信息
    """
    nid = models.BigAutoField(primary_key=True)
    nickname = models.CharField(verbose_name='昵称', max_length=32)

可是，创建表时,出现 如下错误

ERRORS:
app01.UserInfo.groups: (fields.E304) Reverse accessor for 'UserInfo.groups' clashes with reverse accessor for
'User.groups'.
        HINT: Add or change a related_name argument to the definition for 'UserInfo.groups' or 'User.groups'.
app01.UserInfo.user_permissions: (fields.E304) Reverse accessor for 'UserInfo.user_permissions' clashes with r
everse accessor for 'User.user_permissions'.

 reverse accessor for 'UserInfo.user_permissions'.
        HINT: Add or change a related_name argument to the definition for 'User.user_permissions' o 
r 'UserInfo.user_permissions'.

解决方案：

在settings.py中设置:
　　格式：
   　　AUTH_USER_MODEL = "<appname>.表名"

   AUTH_USER_MODEL = "app01.UserInfo"（自己的）
