Also you can't set extra attributes on the instance directly, but instead pass them to the `.save()` method as keyword arguments. The corresponding code would now look like this: if serializer.is_valid(): name = serializer.validated_data['name'] # Inspect validated field data. logging.info('Creating ticket "%s"' % name) - extras = {'user': request.user} # Include the user when saving. - serializer.save(extras=extras) + serializer.save(user=request.user) # Include the user when saving. #### Limitations of ModelSerializer validation. |
