Hello,
I believe there is still a bug here but I am not familiar enough with the
django internals to pinpoint it. I have a similar issue as Przemek where
using a custom `AdminSite` and overriding `default_site` works except that
any newly registered models do not appear in the admin. It would seem the
current test passes since the new class is indeed used but there is no
test case to validate that the registry is correct. Here is an example of
my setup:
**settings.py**
{{{
INSTALLED_APPS = [
"django.contrib.auth",
"django.contrib.contenttypes",
"django.contrib.sessions",
"django.contrib.messages",
"django.contrib.staticfiles",
"myproject.apps.AdminConfig",
"myproject.apps.AppConfig",
]
}}}
**apps.py**
{{{
from django.apps import AppConfig as DefaultAppConfig
from django.contrib.admin.apps import AdminConfig as DefaultAdminConfig
class AdminConfig(DefaultAdminConfig):
default_site = "myproject.admin.AdminSite"
class AppConfig(DefaultAppConfig):
name = "myproject"
verbose_name = "MyProject"
}}}
**admin.py**
{{{
from django.contrib import admin
from .models import MyModel
class AdminSite(admin.AdminSite):
pass
class MyModelAdmin(admin.ModelAdmin):
pass
admin.site.register(MyModel, MyModelAdmin)
}}}
Seemingly, everything is configured correctly as per the documentation.
However, if we inspect the registry at the end of `admin.py` and then
again in `urls.py` I notice that they don't match.
Command: {{{ print(admin.site._registry) }}}
{{{
Registry in admin.py
{<class 'myproject.models.MyModel'>: <myproject.admin.MyModelAdmin object
at 0x7f5e5bc90fd0>}
}}}
{{{
Registry in urls.py
{<class 'django.contrib.auth.models.Group'>:
<django.contrib.auth.admin.GroupAdmin object at 0x7f5e5bc9c7f0>, <class
'django.contrib.auth.models.User'>: <django.contrib.auth.admin.UserAdmin
object at 0x7f5e5bc48780>}
}}}
