What about OOP in Django? Controllers are just functions on module level, models are just "poor" records for storing data (no behaviour), ORM is singleton-based. So I would say it's procedural, not object-oriented, at least, not in Java sense.
Strongly disagree. The internals of Django are full of inheritance and mixins (a form of multiple inheritance), and so are the class-based views and the forms.
The CBV class hierarchy is complex enough that someone had to make this site to help everyone keep them straight: http://ccbv.co.uk/
If you only write FBVs and implement your own views and forms from scratch you can keep your code fairly procedural, but I would say that Django heavily [ab]uses the OOP features of Python.
