How can I implement custom exceptions in Django REST Framework?

How can I implement custom exceptions in Django REST Framework?

You can create custom exceptions by subclassing the APIException class from rest_framework.exceptions. This allows you to define your own error messages and status codes.

Can you show me an example of a custom exception?

Sure! Here's a simple example:

from rest_framework.exceptions import APIException

class CustomNotFound(APIException):
    status_code = 404
    default_detail = 'Resource not found.'
    default_code = 'not_found'

How do I use this custom exception in my views?

You can raise your custom exception in your view like this:

from rest_framework.views import APIView

class MyView(APIView):
    def get(self, request, *args, **kwargs):
        raise CustomNotFound()

What if I want to customize the response further?

You can override the get_full_details method in your custom exception class to customize the response further.
