error pages. However, running with DEBUG set to False means you'll never see errors generated by your site - everyone will just see http://stackoverflow.com/questions/17662928/django-creating-a-custom-500-404-error-page your public error pages. You need to keep track of errors that occur in deployed sites, so Django can be configured to create reports with details about those errors. Email reports¶ Server errors¶ When DEBUG is False, Django will email the users listed in the ADMINS setting whenever https://docs.djangoproject.com/en/1.10/howto/error-reporting/ your code raises an unhandled exception and results in an internal server error (HTTP status code 500). This gives the administrators immediate notification of any errors. The ADMINS will get a description of the error, a complete Python traceback, and details about the HTTP request that caused the error. Note In order to send email, Django requires a few settings telling it how to connect to your mail server. At the very least, you'll need to specify EMAIL_HOST and possibly EMAIL_HOST_USER and EMAIL_HOST_PASSWORD, though other settings may be also required depending on your mail server's configuration. Consult the Django settings documentation for a full list of email-related settings. By default, Django will send email from root@localhost. However, some mail providers reject all email from this address. To use a different sender address, modify the SERVER_EMAIL setting. To activate this behavior, put the email address

The handled exceptions are: Subclasses of APIException raised inside REST framework. Django's Http404 exception. Django's PermissionDenied exception. In each case, REST framework will return a response with an appropriate status code and content-type. The body of the response will include any additional details regarding the nature of the error. Most error responses will include a key detail in the body of the response. For example, the following request: DELETE http://api.example.com/foo/bar HTTP/1.1 Accept: application/json Might receive an error response indicating that the DELETE method is not allowed on that resource: HTTP/1.1 405 Method Not Allowed Content-Type: application/json Content-Length: 42 {"detail": "Method 'DELETE' not allowed."} Validation errors are handled slightly differently, and will include the field names as the keys in the response. If the validation error was not specific to a particular field then it will use the "non_field_errors" key, or whatever string value has been set for the NON_FIELD_ERRORS_KEY setting. Any example validation error might look like this: HTTP/1.1 400 Bad Request Content-Type: application/json
