 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
