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 a code example of a custom exception?

Sure! Here's a simple example:

from rest_framework.exceptions import APIException

class CustomNotFoundException(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 CustomNotFoundException()

What if I want to handle multiple custom exceptions?

You can create multiple custom exception classes and raise them based on different conditions in your views. Just ensure each class has its own status code and message.
