rails: prevent flash message from showing twice

Question

What's the correct way to set a flash message for the current view but not show it for the next request. In other words usually you set the flash message and redirect and the flash message gets shown on the redirect. I don't want to redirect and so I need to make sure the flash message doesn't get shown twice.

make sure that you put your flash massage in any action you want to display, not in application layout — Someth Victory, Jun 20 '12 at 08:10

if you are to 'render' the page, use flash.now[:notice], when you want to 'redirect', use flash[:notice]
