Partial Update Failed via Viewset Django Rest Framework

[Ayo Ayo]

I want to update a field in my model whenever an object link is called through the api. I'm using Django Rest Framework to handle the creation of api.

The link to a single object is

    example.com/api/pk/ where pk is the object id.

In the model viewset, I wrote a partial update method to handle the addition of 1 to the field whenever the object is called upon.

    class RocNationViewSet(viewsets.ModelViewSet):

        queryset=RocNation.objects.filter(is_active=True).order_by('-pub_date')

        serializer_class=RocNationSerializer

        filter_backends = (DjangoFilterBackend,)

   

        def partial_update(self, request, pk=None):

            serializer=RocNationSerializer(rocnation, roc_views=F('roc_views')+1, partial=True)

            serializer.save()

            return Response(serializer.data)

The method is not carrying out the operation. The field in the model is not updated. What am I missing?
