Django (1.10) override AdminSite

Question

I\'ve tried to override AdminSite class with my own custom class. I followed tutorial from django\'s documentation: https://docs.djangoproject.com/en/1.10/ref/contrib/admin

I didn't found the solution to my problem, but I have made a workaround.

First we need to create module in our app (e.g. admin.py) and then extend class AdminSite:

from django.contrib.admin import AdminSite

class MyAdminSite(AdminSite):
    ...

Then on bottom of module we need to create instance of our MyAdminSite and register built-in models from Django:

site = MyAdminSite()
site.register(Group, GroupAdmin)
site.register(User, UserAdmin)

Necessary imports:

from django.contrib.auth.models import Group, User
from django.contrib.auth.admin import GroupAdmin, UserAdmin

In our site url module we need to override original site object:

from .admin import site

admin.site = site
admin.autodiscover()
...
url(r'^admin/', admin.site.urls)
...

Last change we need to do is register our models. One thing we need to remeber is that we can't use register as decorator like that:

@admin.register(MyModel)
class MyModelAdmin(admin.ModelAdmin):
    ...

or:

@admin.site.register(MyModel)
class MyModelAdmin(admin.ModelAdmin):
    ...

We need to define our ModelAdmin class and then call register on our MyAdminSite object:

class MyModelAdmin(admin.ModelAdmin):
    ...
admin.site.register(MyModel, MyModelAdmin)

This is the only solution that is working for me.
