[Django]-Django Rest Framework model serializer with out unique together validation

Django REST framework applies the UniqueTogetherValidator on the serializer. You can remove this by override the validators field in the serializer definition.

class ExampleSerializer(serializers.ModelSerializer):
    class Meta:
        validators = []

Note that this also removes the other unique-check validators that are applied on the model, which might not be the best idea. To avoid that, just override the get_unique_together_validators method on the serializer, to ensure only unique-together check is removed.

class ExampleSerializer(serializers.ModelSerializer):
    def get_unique_together_validators(self):
        """Overriding method to disable unique together checks"""
        return []

You need to remove the validator from the serializer’s list.
