from django.db import models
from django.contrib.auth.models import AbstractUser
# Create your models here.
class User(AbstractUser):
    mobile = models.CharField(max_length=11, unique=True,verbose_name='手机号')

    class Meta:
        db_table='tb_users' #自定义表名
        verbose_name='用户'
        verbose_name_plural=verbose_name  #在admin站点中可以通过这个知道是用户表
    def __str__(self):
        return self.username  #做调试的

 在定义用户模型类时，出现了如下错误:

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

此错误是由于配置中没有对AUTH_USER_MODEL进行配置:

配置完之后在终端进行模型迁移即可：

         python manage.py makemigrations

        python manage.py migrate
