Use one class based view for both List and Retrieve Rest API

Issue

I currently have two different class based views for detailing a specific object and for listing all objects:

class StatusList(ListAPIView):
    permission_classes = (IsAuthenticated,)
    serializer_class = serializers.StatusSerializer

    def get_queryset(self):
        queryset = helperfunctions.getObjects(self.request.user, models.Status)
        return queryset


class StatusDetail(RetrieveAPIView):
    permission_classes = (IsAuthenticated,)
    serializer_class = serializers.StatusSerializer

    def get_queryset(self):
        queryset = helperfunctions.getObjects(self.request.user, models.Status)
        return queryset

Note that helperfunctions.getObjects() simply returns the objects that share the same establishment with the user, so that they can’t see statuses that they shouldn’t.

What I want to know is whether there’s an option to use only one class based view for both StatusDetail and StatusList, which would automatically know that when it gets a pk in the get request it returns the appropriate object, and when it doesn’t, it should return the whole list of objects.

Thanks for any help 🙂

Solution

Use viewsets, like so
:

from rest_framework import viewsets, permissions, mixins    
class StatusDetail(mixins.ListModelMixin, #specify wanted mixins
                       mixins.RetrieveModelMixin,
                       viewsets.GenericViewSet): 
    permission_classes = (IsAuthenticated,)
    serializer_class = serializers.StatusSerializer

    def get_queryset(self):
        queryset = helperfunctions.getObjects(self.request.user, models.Status)
        return queryset
