Django：如何在使用 django-allauth 时从 Django Admin 隐藏站点框架？

Question

背景

我有一个 django 服务器，它使用 django-allauth 来处理身份验证逻辑。我想 unregister 来自 django-admin 的站点框架，换句话说，我不想看到 django-admin 中的站点部分：

我试过的

通常，我会做以下两件事之一：

从 settings.py

INSTALLED_APPS

django.contrib.sites

从我的一个 admin.py 文件中注销 Sites 模型，如下所示：admin.site.unregister(Sites)

问题

我尝试了以上两个选项。这是我从 INSTALLED_APPS 拔下 Google 协作平台应用程序时出现的错误：

...
  File "C:\path-to-my-project\venv\lib\site-packages\allauth\utils.py", line 13, in <module>
    from django.contrib.sites.models import Site
  File "C:\path-to-my-project\venv\lib\site-packages\django\contrib\sites\models.py", line 78, in <module>
    class Site(models.Model):
  File "C:\path-to-my-project\venv\lib\site-packages\django\db\models\base.py", line 113, in __new__
    raise RuntimeError(
RuntimeError: Model class django.contrib.sites.models.Site doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

django-allauth 显然在第 13 行中使用了它。

这是我执行 admin.sites.unregister(Site):

时的错误

问题是 django-allauth 需要站点框架才能正常工作。这里是 the official explanation:

settings.py (Important - Please note ‘django.contrib.sites’ is required as INSTALLED_APPS):

我想要的

我只想对 django-admin 隐藏站点部分，因为我用不着它。我不想拔出或注销，因为我希望 django-allauth 的功能完好无损。我如何实现这一目标？我错过了什么？

重现错误的步骤

创建一个安装了 django-allauth 的 Django 项目
创建超级用户并登录到 Django admin
尝试对 Django 管理员隐藏站点框架

Answer 1

一种方法是在您的 AppConfig.ready() 功能之一上注销 Site 管理员，如下所示：

from django.apps import AppConfig


class SomeAppConfig(AppConfig):
    # ...

    def ready(self):
        from django.contrib import admin
        from django.contrib.sites.models import Site
        admin.site.unregister(Site)

发生错误是因为在您的 admin.py 之一上取消注册并不能保证 django.contrib.sites 的注册已经完成。在 ready() 函数中执行此操作将有效，因为所有应用程序都已与其管理员一起注册。
