Changing Application Error (Rails) to something pretty?

Hello all,

I have installed the Exception Notifier plugin to email me when my rails
application encounters an exception. However, I would like to prevent my
users from seeing the “Application Error (Rails)” screen in production.
Ideally, it would be nice to have an error message within my site
layout. I
know people have asked this question before but I can’t seem to find it
in
my search.

Any suggestions? thanks all,

Jin

you can change the 500.html file in /public
