python - Update/append serializer.data in Django Rest Framework -

how can update/append serializer.data in django rest framework?

data = serializer.data.update({"item": "test"}) not working

return response(serializer.data, status=status.http_201_created)

serializer.data <class 'rest_framework.utils.serializer_helpers.returndict'>

unfortunately, serializer.data immutable. instead of adding items serializer.data can copy serializer.data dict. can try this:

newdict={'item':"test"} newdict.update(serializer.data) return response(newdict, status=status.http_201_created)
