Django rest framework error object X has no attribute 'get_extra_actions'

Question

I am wanting to add some search functionality to my API and I followed this simple guide but I'm still getting the error

type object 'ClientViewSet' has no attribute 'get_extra_actions'

---

My setup

Versions

• Django: 2.2.5
• Django Rest Framework: 3.11.0
• Python: 3.8.2

models.py

class Client(models.Model):
    phone = models.CharField(max_length=10)

urls.py

router = routers.DefaultRouter()
router.register(r'clients', ClientViewSet)

urlpatterns = [
    path('api/', include(router.urls)),
    path('api-auth/', include('rest_framework.urls', namespace='rest_framework')),
]

serializers.py

class ClientSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = Client
        fields = '__all__'

views.py

class ClientViewSet(generics.ListAPIView):
    queryset = Client.objects.all()
    serializer_class = ClientSerializer
    filter_backends = [filters.SearchFilter]
    search_fields = ['phone']

Answer 1

To build off the answer provided here, a ViewSet needs to inherit from a ViewSet and the ListAPIView class does not inherit from ViewSet.

A way to get this to work, however, is to change the inherited class from ListAPIView to ModelViewSet like this:

class ClientViewSet(viewsets.ModelViewSet):
    queryset = Client.objects.all()
    serializer_class = ClientSerializer
    filter_backends = [DjangoFilterBackend]
    filter_fields = ['phone']

Answer 2

"You've called it a viewset, but that doesn't make it one; you inherit from APIView which is a standalone generic view, not a viewset.

A viewset needs to inherit from viewsets.ViewSet."
