No Model Inheritence in Django?

Based on this wiki page on Model Inheritance and this hack on extending models (yuck) not looking too good. I would guess this "just works" in Rails, since I've just redesigned my database now would be the time to switch but I really want Django's admin interface.

Not Too Happy with Django Migration

So after playing around with dmigration and dbmigration I'm probably going back to mucking with SQL (which I'm even less happy) or maybe hacking something together that meets my needs and actually works.
