Django REST Custom Errors

api, django, python

Solution

As Bibhas said, with custom exception handlers, you only can return own defined errors when an exception is called. If you want to return a custom response error without exceptions being triggered, you need to return it in the view itself. For example:

    return Response({'detail' : "Invalid arguments", 'args' : ['arg1', 'arg2']}, 
                     status = status.HTTP_400_BAD_REQUEST)

Problem

I’m trying to create a custom error response from the REST Django framework. I’ve included the following in my views.py, ``` from rest_framework.views import exception_handler def custom_exception_handler(exc): """ Custom exception handler for Django Rest Framework that adds the `status_code` to the response and renames the `detail` key to `error`. """ response = exception_handler(exc) if response is not None: response.data['status_code'] = response.status_code response.data['error'] = response.data['detail'] response.data['detail'] = "CUSTOM ERROR" return response ``` And also added the following to settings.py. ``` REST_FRAMEWORK = { 'DEFAULT_PERMISSION_CLASSES': ( 'rest_framework.permissions.AllowAny', ), 'EXCEPTION_HANDLER': 'project.input.utils.custom_exception_handler' } ``` Am I missing something as I don’t get the expected response. i.e a custom error message in the 400 API response. Thanks,
