Demystifying Mixins with Django
summary
Mixins are ordinary Python classes not magic and work by wiring behavior into Django class based views; a concrete login required mixin is implemented by overriding dispatch override to raise PermissionDenied and then calling super which actually protects pages; external packages like Django Braces and upcoming Django 1.9 mixins replace most handrolled code; a demo shows a dynamic class swap that mutates instances (works differently in Python 2 vs 3) and warns that two mixins is common while six becomes a nightmare.
