First, make sure you've read:
https://docs.djangoproject.com/en/1.4/howto/error-reporting/ In your case you might do any of the following: 1) Customize the 500.html server error template to provide a more user-friendly message. 2) Customize the server error view, which by default just renders the 500.html template: https://docs.djangoproject.com/en/1.4/topics/http/views/#the-500-server-error-view 3) Use a middleware to customize completely how otherwise unhandled errors are processed. You can create a customized 500 (or 503) response and do whatever admin notification and other processing you want. -- You received this message because you are subscribed to the Google Groups "Django users" group.
