How do I validate serializers in Django REST Framework?

In Django REST Framework, you can validate serializers by overriding the validate method or using field-level validation.

Can you give me an example of field-level validation?

Sure! You can define a custom validation method for a field by naming it validate_<field_name>. For example, validate_email can be used to check if the email is valid.

What if I want to validate multiple fields together?

You can override the validate method in your serializer to perform validation that involves multiple fields. Just raise a serializers.ValidationError if the validation fails.

Are there built-in validators I can use?

Yes, Django REST Framework provides several built-in validators like UniqueValidator, MaxLengthValidator, and more that you can use in your serializers.
