Django 自定义用户错误：提示：向“custom_auth.CustomUser.groups”或“auth.User.groups”的定义添加或更改 related_name 参数

Question

我需要帮助。我正在 Django 中创建一个注册/登录应用程序，但在迁移 CustomUser 类时遇到一些问题。以下是错误：

SystemCheckError: System check identified some issues:

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

我尝试添加一个相关名称，作为对此处类似问题的建议，但当我进行迁移时，它仍然会抛出相同的错误。

我的 models.py 的代码如下：

# custom_auth/models.py
from django.contrib.auth.models import AbstractUser
from django.db import models

# Create your models here.
class CustomUser(AbstractUser):
    phone_number = models.CharField(max_length=15)
    designation = models.CharField(max_length=100)

    # Add a related_name to the user_permissions field
    user_permissions = models.ManyToManyField(
        to='auth.Permission',
        related_name='custom_users',
        blank=True,
    )

Answer 1

您必须覆盖组并为其指定相关名称

custom_groups = models.ManyToManyField(
        Group,
        related_name='custom_users',
        blank=True,
    )

将其添加到您的自定义用户模型中
