Django ModelViewSet PATCH request return model fields updated
class MerchantStampCardViewSet(viewsets.ModelViewSet):
'''
A view set for listing/retrieving/updating/deleting stamp cards for the current
merchant
'''
permission_classes = (IsMerchantAndAuthenticated, )
def get_queryset(self):
if len(MerchantProfile.objects.filter(user=self.request.user)) > 0:
merchant_profile = MerchantProfile.objects.get(user=self.request.user)
if merchant_profile.merchant:
return StampCard.objects.filter(merchant=merchant_profile.merchant)
return None
def get_serializer_class(self):
if self.request.method == 'GET':
return StampCardSerializerWithRewards
else:
return StampCardSerializer
I'm trying to make this code return the fields changed in the response body. The model class has a couple fields like name, city, province, zip code and address and through the front-end the user can only change one at a time, but I want the body of the 200 response to contain the field name changed and the new value just to confirm that a change was successful and nothing went wrong.
So for example if the user changes the name to Billy. The response should be 200 and the body should say {name : 'Billy'}
How do I do this?

You can try like this:
class YourViewSet(...):
def update(self, request, *args, **kwargs):
instance = self.get_object()
current_data = self.get_serializer(instance).data # collect current data
# next few lines of the code is from default implementation
serializer = self.get_serializer(instance, data=request.data, partial=partial)
serializer.is_valid(raise_exception=True)
self.perform_update(serializer)
if getattr(instance, '_prefetched_objects_cache', None):
instance._prefetched_objects_cache = {}
updated_data = serializer.data # now we get the updated data
response_dict = dict()
for key, value in current_data:
# find the differences
if updated_data.get(key) != value:
response_dict[key] = updated_data.get(key)
return Response(response_dict) # send the difference through response
Here I have put a override on update method. Then I have collected the dictionary data from current object and updated object. Then compared them and sent differences in a dictionary as response. FYI its an untested code.
