Django 管理中同一模型的多个 ModelAdmins/视图
如何为同一模型创建多个 ModelAdmin,每个模型的定制方式不同并链接到不同的 URL?
假设我有一个名为 Posts 的 Django 模型。默认情况下,该模型的管理视图将列出所有 Post 对象。
我知道我可以通过设置 list_display 等变量或覆盖 ModelAdmin 中的 queryset
方法,以各种方式自定义页面上显示的对象列表,如下所示:
class MyPostAdmin(admin.ModelAdmin):
list_display = ('title', 'pub_date')
def queryset(self, request):
request_user = request.user
return Post.objects.filter(author=request_user)
admin.site.register(MyPostAdmin, Post)
默认情况下,可以通过 URL <代码>/admin/myapp/post。但是,我希望拥有同一模型的多个视图/模型管理员。例如 /admin/myapp/post
将列出所有帖子对象,而 /admin/myapp/myposts
将列出属于该用户的所有帖子,而 /admin/ myapp/draftpost
可能会列出所有尚未发布的帖子。 (这些只是示例,我的实际用例更复杂)
您不能为同一模型注册多个 ModelAdmin(这会导致 AlreadyRegistered
异常)。理想情况下,我希望实现此目标,无需将所有内容放入单个 ModelAdmin 类中并编写自己的“url”函数以根据 URL 返回不同的查询集。
我查看了 Django 源代码,发现像 ModelAdmin.changelist_view
这样的函数可以以某种方式包含在我的 urls.py 中,但我不确定它到底是如何工作的。
更新:我找到了一种实现我想要的功能的方法(见下文),但我仍然想听听其他实现此目的的方法。
How can I create more than one ModelAdmin for the same model, each customised differently and linked to different URLs?
Let's say I have a Django model called Posts. By default, the admin view of this model will list all Post objects.
I know I can customise the list of objects displayed on the page in various ways by setting variables like list_display or overriding the queryset
method in my ModelAdmin like so:
class MyPostAdmin(admin.ModelAdmin):
list_display = ('title', 'pub_date')
def queryset(self, request):
request_user = request.user
return Post.objects.filter(author=request_user)
admin.site.register(MyPostAdmin, Post)
By default, this would be accessible at the URL /admin/myapp/post
. However I would like to have multiple views/ModelAdmins of the same model. e.g /admin/myapp/post
would list all post objects, and /admin/myapp/myposts
would list all posts belonging to the user, and /admin/myapp/draftpost
might list all posts that have not yet been published. (these are just examples, my actual use-case is more complex)
You cannot register more than one ModelAdmin for the same model (this results in an AlreadyRegistered
exception). Ideally I'd like to achieve this without putting everything into a single ModelAdmin class and writing my own 'urls' function to return a different queryset depending on the URL.
I've had a look at the Django source and I see functions like ModelAdmin.changelist_view
that could be somehow included in my urls.py, but I'm not sure exactly how that would work.
Update: I've found one way of doing what I want (see below), but I'd still like to hear other ways of doing this.

我找到了一种方法来实现我想要的,即使用代理模型来绕过每个模型只能注册一次的事实。
然后,可以在
/admin/myapp/post
访问默认的PostAdmin
,并且用户拥有的帖子列表将位于/admin/myapp/myposts< /代码>。
在查看 http://code.djangoproject.com/wiki/DynamicModels 后,我来了使用以下函数实用程序函数来执行相同的操作:
可以按如下方式使用:
I've found one way to achieve what I want, by using proxy models to get around the fact that each model may be registered only once.
Then the default
PostAdmin
would be accessible at/admin/myapp/post
and the list of posts owned by the user would be at/admin/myapp/myposts
.After looking at http://code.djangoproject.com/wiki/DynamicModels, I've come up with the following function utility function to do the same thing:
This can be used as follows:
保罗·斯通的回答绝对很棒!只是补充一下,对于 Django 1.4.5,我需要从
admin.ModelAdmin
继承我的自定义类Paul Stone answer is absolutely great! Just to add, for Django 1.4.5 I needed to inherit my custom class from
admin.ModelAdmin
根据正确答案,我对
AdminSite
类进行了猴子修补,并添加了register_via_proxy
方法以使任务变得更容易。使用方法如下:
Based on the correct answers, I monkeypatch the
AdminSite
class and add the methodregister_via_proxy
to make the task easier.And to use is like:
