I have a Model serializer. This is

Answer 1

class DetailView(APIView):
    def get_object(self, pk):
        return TestModel.objects.get(pk=pk)

    def patch(self, request, pk):
        testmodel_object = self.get_object(pk)
        serializer = TestModelSerializer(testmodel_object, data=request.data, partial=True) # set partial=True to update a data partially
        if serializer.is_valid():
            serializer.save()
            return JsonResponse(code=201, data=serializer.data)
        return JsonResponse(code=400, data="wrong parameters")

Documentation
You do not need to write the partial_update or overwrite the update method. Just use the patch method.
