Re-post: Problem with dashes in URL / Routes

Hey Guys!

First, I am a complete noob at rails. This is my first attempt at a website using ruby. I've done quite a bit of searching and can't seem to find the answer to this question. I'm sure its something completely obvious I'm missing, lol.

I'm having a little issue getting "link_to" to generate URL's with "-" instead of "+". Some of my URL's may have a variable on the end that could have spaces ( ie. domain.com/controller/action/some+variable/ ). I would like to replace that "+" with a "-" and then remove the dash before I query the database with that variable. Is it possible to have the routes do this automatically? Would I use a regex with :requirements?

Thanks in Advance, Nick
