CBV doesn't require you to do anything in particular other than implement retrieve/list/etc. methods on the GenericViewSet as needed, and get/post/etc. on GenericAPIView. You can use the convenience methods in Django and mixins, but as soon as you get beyond a simple case, they start to become a hindrance.

The only thing beyond that that I'd recommend is specifying a get_serializer_class method since it simplifies your boilerplate and plays well with drf-spectacular for generating your API documentation. I generally don't use ModelSerializer unless the logic is very simple, I've been meaning to write a blog post for a long while about avoiding it when your data model is split across two database tables.

In my current codebase there is a lot more overriding going on than simply implementing the retrieve/list/etc... methods. On a quick review I found overrides for: - get_object - get_serializer_class - perform_create - get_queryset - get_serializer_context - perform_destroy

It depends on how much you want to rely on Mixins and using Serializer classes to do more than just serialise JSON. Neither of those are compulsory to use, and the more you lean into them the more inheritance you’re forced to do as soon as you need to customise the behaviour.
