Django Admin Site Namespace Reverse URLS

I was having an odd issue where {% url ‘custom_admin:foo_bar_changelist’ %} would work from one admin but not another location. I put it on Stack Overflow… got an answer that one can manually construct the adminsite include via include(adminsite.get_urls(), ‘app_name’, ‘namespace’).
