Bug in admin models?

[Derek]

I am trying to add a model entry, via the admin; I get this error (which has not happened before), running Django on Ubuntu 12.04 with the test server.  Not sure if there is an error with the model (which has worked fine up to now) or ...?

Can't see the django.contrib.admin in INSTALLED_APPS.

Yes, its there - the line after 'suit'.

In installed apps you have s2.myapp, the traceback is just myapp.  Also you have 's2.myapp, in the installed_apps, should it not be 's2.myapp', (ie missing the end quote)?

Yes, I simplified the names in the installed list and traceback, and as result probably altered the correct grammer slighlty ... but I am hoping that someone who understand the "innards" of the Django admin can point what is _actually_ wrong; given that the error trace is not actually referencing any lines in my app/project.

Sorry, I didn't see the django.contrib.admin. You're overrriding the add method for you model? Because it's appear the add method is returning None:
