For example, say you generate some scaffolding, run the migration, and then realize your scaffolding command should have been singular (ruby script/generate scaffo...
I have a site which uses AJAX and preloaders. Now I would like to see the impact of these preoloaders before deploying the site online.

For example, I might make three individual calls to three individual tables, and I want the results combined, and sorted by a common column. Here's a super basic code example that will hopefully make my question easier to understa...

Ok, I have been suck on it for hours. I thought net/imap.rb with ruby 1.9 supported the idle command, but not yet. Can anyone help me in implementing that?
