Hi folks, I'm looking for some advice on the best way to provide a single place where ajax status/error messages are displayed for a rails app. This is similar to the rails flash subsystem, but for ajax requests.

In my Rails controller I want to branch to a different controller's action, show its view and then return back to my original action, i.e. it's not a simple redirect, more like a sub-procedure call. I want to use this whenever a user does something suspicious, like editing a post too often in a row. I still want to allow the edit, but f...
