Django: HINT: Add or change a related_name argument to the definition for 'auth.User.user_permissions' or 'xxx.User.user_permissions'.

(venv) user@ubuntu:~/PycharmProjects/test_project/test_django/test_django/apps/xxx$ python ../../../manage.py makemigrations

提示：

HINT: Add or change a related_name argument to the definition for 'auth.User.user_permissions' or 'xxx.User.user_permissions'.

原因：models.py中定义了用户模型类，但没有在setting.py中扩展django的用户认证模型：

from django.contrib.auth.models import AbstractUser

# Create your models here.
class User(AbstractUser):
    pass

解决方法
扩展django的用户认证模型：

#setting.py
AUTH_USER_MODEL = 'xxx.User'
