How to change validation error responses in DRF?

Question

I want to change the JSON, which rest_framework or django returns when a validation error occures.

I will use one of my views as example, but I want to change error mess

Answer 1

The easiest way to change the error style through all the view in your application is to always use serializer.is_valid(raise_exception=True), and then implement a custom exception handler that defines how the error response is created.
