How can I customize error responses in Django REST Framework?

You can customize error responses in Django REST Framework by overriding the handle_exception method in your views.

Can you show me an example of how to do that?

Sure! Here's a simple example:

from rest_framework.views import exception_handler

class CustomExceptionHandler:
    def __init__(self, request, response):
        self.request = request
        self.response = response

    def handle_exception(self, exc):
        response = exception_handler(exc, self.request)
        if response is not None:
            response.data['custom_error'] = 'Your custom message here'
        return response

What if I want to customize the error message based on the type of exception?

You can check the type of exception in the handle_exception method and customize the response accordingly. For example:

if isinstance(exc, YourSpecificException):
    response.data['custom_error'] = 'Specific error message'
else:
    response.data['custom_error'] = 'General error message'
