        Read-only fields are included in the API output, but should not be included in the input during create or update operations. Any 'read_only' fields that are incorrectly included in the serializer input will be ignored.
        Set this to True to ensure that the field is used when serializing a representation, but is not used when creating or updating an instance during deserialization.
