Python 3.6, Django 1.11.20, dev
server on Windows 10.
Haven't been *able* to get it
working yet on Ubuntu 16.04 with Python 2.7 and haven't tried
it yet on Python 2.7 on the dev server.
Getting Python 3.x running with
Apache2 on Ubuntu is non-trivial due to co-existence with Trac
(2.7 only) which also requires my SVN to cohabit on the same
machine.
Django Admin is customizable to an extent, but at a certain point those customizations can cost you more time than they save, and it makes more sense to build your business logic in a standard app/view. Without digging into your code, my spidey sense tells me your app is at that point - stop trying to do it in the admin and you'll have all the control you need or want../s
