django admin将auth模型移动到另一个部分

Question

我正在使用Django 2.x.

我通过在authentication应用程序中扩展AbstractModel来创建自定义用户模型

class User(AbstractUser):
    pass

并在设置中更新

AUTH_USER_MODEL = 'authentication.User'

这导致管理面板中有两个部分。一节认证包含用户模型，而默认认证和授权仅包含组模型。

我想将用户移动到身份验证和授权或将组移动到身份验证，以便两个模型可以在一个部分中。

为此，我在authentication.admin.py中添加了这个

apps.get_model('auth.Group')._meta.app_label = 'authentication'

将组移至身份验证。

跑完之后

python manage.py makemigrations

它在django的auth应用程序中生成迁移

Migrations for 'auth':
  /Users/anuj/.local/share/virtualenvs/originor_py-Vd6fDdN7/lib/python3.6/site-packages/django/contrib/auth/migrations/0010_auto_20190220_0238.py
    - Remove field permissions from group
    - Alter field groups on user
    - Delete model Group

在迁移迁移./manage.py migrate时，它会给出错误

ValueError: The field auth.User.groups was declared with a lazy reference to 'authentication.group', but app 'authentication' doesn't provide model 'group'.

如何将Group模型移动到Django管理员的另一部分？ 我是否需要创建自定义组模型？

Answer 1

你已经覆盖了继承AbstractUser和AbstractBaseUser的PermissionsMixin，如下所示class AbstractUser(AbstractBaseUser, PermissionsMixin):

你可以在groups中看到django.contrib.auth.models.PermissionsMixin属性

class PermissionsMixin(models.Model):
    """
    A mixin class that adds the fields and methods necessary to support
    Django's Group and Permission model using the ModelBackend.
    """
    ...
    groups = models.ManyToManyField(
        Group,
        verbose_name=_('groups'),
        blank=True,
        help_text=_(
            'The groups this user belongs to. A user will get all permissions '
            'granted to each of their groups.'
        ),
        related_name="user_set",
        related_query_name="user",
    )
    ...

创建CustomGroup模型并将该模型添加到groups属性，如下所示。

class User(AbstractUser):
    ...
    groups = models.ManyToManyField(
        CustomGroup,
        verbose_name=_('groups'),
        blank=True,
        help_text=_(
            'The groups this user belongs to. A user will get all permissions '
            'granted to each of their groups.'
        ),
        related_name="user_set",
        related_query_name="user",
    )
    ...

这将帮助您覆盖使用Group模型更改的默认CustomGroup模型
