Django 将对象级权限添加到其他应用程序的管理界面（例如auth）

我使用django guardian获得对象级权限。如何将其集成到自己的代码中的文档很好：

---

但我如何才能将其添加到其他应用程序的模型中？我不想修改例如django.contrib.auth的代码。

我在django reversion的源代码中找到了一个解决方案。有一个名为

patch\u admin（）

的助手。以下是为django guardian修改的代码片段

# Copy of django-reversion helpers.py
def patch_admin(model, admin_site=None):
    """
    Enables version control with full admin integration for a model that has
    already been registered with the django admin site.

    This is excellent for adding version control to existing Django contrib
    applications. 
    """
    admin_site = admin_site or admin.site
    try:
        ModelAdmin = admin_site._registry[model].__class__
    except KeyError:
        raise NotRegistered, "The model %r has not been registered with the admin site." % model
    # Unregister existing admin class.
    admin_site.unregister(model)
    # Register patched admin class.
    class PatchedModelAdmin(GuardedModelAdmin, VersionAdmin, ModelAdmin): # Remove VersionAdmin, if you don't use reversion.
        pass
    admin_site.register(model, PatchedModelAdmin)

from django.contrib.auth.models import Group
patch_admin(Group)
