Add tests for unique validation for bulk creation in model serializers #6396
Conversation
The unique validation in model serializers only check for existing entries on the database. If the serializer is instanced with many=True and receives more than one item in the data argument having the same value for a unique field, the .is_valid() method returns True, but calling .save() will raise an IntegrityError.

Will do. Thanks! I looked into the model serializer classes, but couldn't decide on a good path to put the logic of calling this validation. Especially on how to add errors to the list serializer. I'd love to hear any suggestions. For now I thought of adding a note to the docs with the example I described on the related issue #6395. |
