How to PATCH a single field using Django Rest Framework?

Question

I have a model \'MyModel\' with many fields and I would like to update a field \'status\' using PATCH method. I\'m using class based views. Is there any way to implement PAT

Answer 1

I struggled with this one for a while, but it is a very straightforward implementation using generic views or a combination of generic views and mixins.

In the case of using a generic update view (generics.UpdateAPIView), just use the following code, making sure the request type is PATCH:

class UpdateUser(generics.UpdateAPIView):

    queryset = User.objects.all()
    serializer_class = UserSerializer

There's nothing else to it!

If you're using an update mixin (mixins.UpdateModelMixin) in combination with a generic view (generics.GenericAPIView), use the following code, making sure the request type is PATCH:

class ActivateUser(mixins.UpdateModelMixin, generics.GenericAPIView):

    serializer_class = UserSerializer
    model = User
    lookup_field = 'email'

    def get_queryset(self):
        queryset = self.model.objects.filter(active=False)
        return queryset

    def patch(self, request, *args, **kwargs):
        return self.partial_update(request, *args, **kwargs)

The second example is more complex, showing you how to override the queryset and lookup field, but the code you should pay attention to is the patch function.
