auth.User.groups:（fields.E304）“User.groups”的反向访问器与“UserManage.groups”的反向访问器冲突

Question

在我的Django项目中，我有一个user_manage应用程序。

我在我的user_manage应用程序的model.py中创建了一个名为UserManage的模型：

from django.db import models
from django.contrib.auth.models import AbstractUser

class UserManage(AbstractUser):
    username = models.CharField(max_length=12)

然后我跑：

$ python3 manage.py makemigrations

出现错误：

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

感谢@ABDULNIYASPM

我加上：

AUTH_USER_MODEL = "users_management.UserManage" 

在settings.py中它起作用。

模板是

AUTH_USER_MODEL='你的appname.YourClassName>；'

YourAppName：这是将具有用户模型的应用程序的名称 YourClassName：这是在models.py文件中使用的类的名称

将此添加到设置中：

AUTH_USER_MODEL = 'APPNAME.User'

这样我们就告诉Django使用我们的自定义模型而不是默认模型。 https://docs.djangoproject.com/en/2.2/topics/auth/customizing/#substituting-a-custom-user-model
