Custom AdminSite won't load installed_apps

Hello,
I am trying to customize the AdminSite in order to add more pages to the admin section.
I override the default django.contrib.site and its urls method. However, using this method none of the installed apps are available in the context. Consequently none of the installed apps, except for my own apps (who are registered explicitly with the custom admin site) appear in the admin index page.

Pls advise
Thanks

Ok, Figured it out…

Added

from django.contrib.admin import sites

admin.site = admin_site

to the main app’s admin module.
