The UniqueValidator is a validator provided by the Django REST framework in Python. It is used to enforce unique constraints on a field within a serializer class. This validator ensures that the value of the field is unique among the existing instances of the corresponding model in the database. If a duplicate value is found, it raises a validation error indicating that the field must have a unique value. This validator is often used with serializers to perform uniqueness checks during data validation and maintain data integrity.
