ModelAdmin 的重写方法
我正在开发一个 Django 项目，每当管理员在管理控制台 (CRUD) 中执行某些操作时，就会通知一组人。有人向我指出 ModelAdmin 上的三个方法，称为 log_addition、log_created 和 log_deleted，它们将所有必要的信息保存到一个名为“django_admin_log”的特殊数据库中。
我将以下代码放入我的 admin.py 中：
class ModelAdmin(admin.ModelAdmin):
def log_addition(self, request, object):
subject = 'admin test of creation'
message = 'admin creation detected'
from_addr = '[email protected]'
recipient_list = ('[email protected]',)
send_mail(subject, message, from_addr, recipient_list)
return super(ModelAdmin, self).log_addition( *args, **kwargs )
但是，当我创建新用户时，此代码会被忽略。许多帖子实际上建议创建一个不同的类名（MyModelAdmin），我不完全确定为什么 - 重点是覆盖现有模型。我尝试过，但结果相同。有人能指出我正确的方向吗？究竟如何重写现有类的方法并赋予它一些额外的功能？ 谢谢你！ Luka
编辑：我想通了，似乎我必须取消注册并重新注册用户才能使我的更改生效。
I am working on a Django project where any time an admin does something in the admin console (CRUD), a set of people gets notified. I was pointed to three methods on ModelAdmin called log_addition, log_created and log_deleted which save all the necessary info into a special database called "django_admin_log".
I placed the following code into my admin.py:
class ModelAdmin(admin.ModelAdmin):
def log_addition(self, request, object):
subject = 'admin test of creation'
message = 'admin creation detected'
from_addr = '[email protected]'
recipient_list = ('[email protected]',)
send_mail(subject, message, from_addr, recipient_list)
return super(ModelAdmin, self).log_addition( *args, **kwargs )
This code however, gets ignored when I create new users. Many posts actually recommend to create a different class name (MyModelAdmin) and I am not entirely sure why - the point is to override the existing model. I tried it, but with the same result. Can anyone point me in the right direction please? How exactly do you override a method of an existing class and give it some extra functionality?
Thank you!
Luka
EDIT: I figured it out, it seems that I had to unregister and re-register User for my change to work.

如果这不起作用，您可以将代码放入名为 add_view 的函数中：
可以覆盖此函数以向管理员视图添加功能。如果您查看管理代码：
https:// /code.djangoproject.com/browser/django/trunk/django/contrib/admin/options.py#L923
你会看到你尝试过的功能overwrite 是从 add_view 函数中调用的，因此您也可以将代码放在这里
remove the return at the end.
If that doesn't work, you can instead put the code in a function called add_view:
This function can be overwritten to add functionality to the admin's view. If you look at the admin code:
https://code.djangoproject.com/browser/django/trunk/django/contrib/admin/options.py#L923
you will see that the function you have tried to overwrite is called from within the add_view function so you could equally put the code here
