Vim can do ctags out of the box. If I remember right, the command is C-] (ctrl+ close bracket) to jump to a ctags definition.

For rails projects I wrote a script that kicks off ctags with the following options. "ctags --tag-relative -Rf.git/tags.$$ --exclude=.git --exclude=log --exclude=tmp --exclude=public --languages=ruby --languages=javascript `bundle show --paths` $MY_RUBY_HOME ."

I'd wager there is a better way. That's just the way I roll.
