What are Django serializer validators and how do I use them?

Django serializer validators are used to validate data before it is saved to the database. They ensure that the data meets certain criteria.

Can you give me an example of how to implement a custom validator?

Sure! You can create a custom validator by defining a function that raises a serializers.ValidationError if the data is invalid. Then, you can use it in your serializer like this: validators=[my_custom_validator].

What built-in validators does Django provide?

Django provides several built-in validators like MaxValueValidator, MinValueValidator, and EmailValidator. You can use them directly in your serializers.

How do I handle validation errors in my API response?

You can handle validation errors by catching the serializers.ValidationError in your view and returning a response with the error details.
