What are some effective validation techniques for Django serializers?

Django serializers provide several validation techniques, such as field-level validation, object-level validation, and custom validators. Would you like to know more about a specific technique?

Can you explain field-level validation?

Field-level validation allows you to validate individual fields in your serializer. You can override the validate_<field_name> method to implement custom validation logic for that specific field.

What about object-level validation?

Object-level validation is used to validate the entire object after all fields have been validated. You can override the validate method in your serializer to implement this.

Are there any built-in validators I can use?

Yes, Django provides several built-in validators like MaxValueValidator, MinValueValidator, and EmailValidator. You can use these in your serializer fields.
