API

is_valid() is extended with model.full_clean() api.

serializer_obj.is_valid(self, raise_exception=False, include=None, validate_unique=True, *args, **kwargs)

• raise_exception=False
• validate_unique=True
• include=None
  • This parameter accept a type of dict: {'model_field_name' : instance_obj} and perform exclude=None method to Model.full_clean() api.
  • If you want to perform Model.full_clean() you must have the model instance with ALL FIELD POPULATED.
  • Into some scenario, for example, when you try to save nested instance, some ForeignKey are None. So before validate you must create an instance of this ForeignKey without save into db and pass it into include=None parameter. This action exclude it, by Model.full_clean() validation, but not from Model.clean() method. A ForeignKey with pk=None can't be validated by Model.clean_field() method.
