app.ready() is called after models ready, but the site's urlpatterns are
not parsed yet, so how to add code after the whole site is ready, so that
we can update models and reverse urls?

{{{
from django.apps import AppConfig
from django.urls import reverse

class Test002Config(AppConfig):
name = 'test002'

def ready(self):
try:
url = reverse("admin:auth__user__changelist")
print(url)
# reverse raise errors
except Exception as error:
pass
# the admin site broken even we try...catch.. here
# the admin site can login, but got error in admin index page

}}}

Comment:

Please don't use Trac as a support channel. Also, there is a typo in your
example, it should be `admin:auth_user_changelist`.

Closing per TicketClosingReasons/UseSupportChannels.
