    address = [1]()

    def validate_name(self, value):
        if len(value) < [2]:
            raise serializers.ValidationError("Name too short")
        return value

    def validate(self, data):
        if data['name'] == 'admin' and data['address']['street'] == [3]:
            raise serializers.ValidationError("Admin cannot live on this street")

💡 Hint

Common Mistakes

Using 'CharField' for the nested address instead of a serializer field.

Setting the minimum length too high or too low.

Using the wrong street name in validation.

AddressSerializer() defines a nested serializer for the address field. The minimum name length is 5, and admin users cannot live on "Forbidden Street".
