在Django中注销第三方ModelAdmin会导致NotRegistered错误 [英] Unregistering a third-party ModelAdmin in Django causes NotRegistered error

问题描述

我想从管理站点中的第三方模块（ otherapp ）完全隐藏模型。

I want to completely hide a model from a third-party module (otherapp) in admin site.

我将 admin.site.unregister（ModelToHide）放在我的一个应用程序管理员（ myapp ），但会在每个页面上导致 NotRegistered 错误。问题是之前 otherapp.admin 加载了 myapp.admin 。

I put admin.site.unregister(ModelToHide) in one of my apps' admin (myapp), but it causes NotRegistered error on every page. The problem is that myapp.admin is loaded before otherapp.admin.

我试图更改订单 INSTALLED_APPS ，以便在 otherapp 之前出现 myapp ，但这没有帮助，Django以相反的顺序加载它们。根据Django的书，我读了一条SO评论说， INSTALLED_APPS 的顺序无关紧要。

I tried to change the order INSTALLED_APPS so that otherapp comes before myapp, but it did not help, Django loads them in reverse order. I read in one of the SO comments that order of INSTALLED_APPS does not matter, as per Django book.

实际上，我提出这个问题只是为了分享我对它的工作方式，因为花了一些时间来找出解决方案。希望这对某人有帮助。

Actually, I created this question just to share the way I made it work for me, because it took some time to figure out the solution. Hope this helps someone.

推荐答案

有两种选择：

1. 在 admin.autodiscover（）之后放置 admin.site.unregister（ModelToHide） urls.py，以便在所有模型都注册后运行。


2. 将导入内容添加到 myapp.admin ： import otherapp.admin 使其首先被加载。

1. Put admin.site.unregister(ModelToHide) just after admin.autodiscover() in urls.py so that it runs after all models have been registered.
2. Add an import to myapp.admin: import otherapp.admin so that it's loaded first.
