Serializers & Permissions Per Action

[ruslan-korneev]

I would like to add these useful mixins, needed when you wanna use a ViewSet and different serializers/permissions for different actions, usage should be something like:

class GuitarViewSet(SerializerPerAction, ModelViewSet):
    ...
    action_serializers = {
        "default": GuitarDefaultSerializer,  # this serializer would be default, in this example for actions: create, retrieve, destroy, update, partial-update
        "list": GuitarListSerializer,
        "custom": GuitarCustomSerializer,
    }
    ...

    @action(details=False, ...):
    def custom(self, request, ...):
        ...

the same goes for PermissionPerAction

What are the advantages of using this instead of multiple views?

We will have less code. A lot of developers, teams, companies use only ViewSets, or only GenericAPIViews, or both, but ViewSet as a very valuable tool does not have a solution to simply add different serializers and permissions. We always have to override get_serializer_class or get_permissions in that case
