Hey there,
Easy questions for you guys (and gals). I've only been studying ruby/rails for about 2 days, so bare with me

In one of my controllers I'm doing something like:

def view_listing
id = params[:listing]
@listing = Listing.find(id)

basically, trying to show the details on a specific listing. If it is called like
website.com/controller/view_listing/219, i get params[:id] equal to 219, right?

Also, how do I verify that it is actually an int (sql safe.)
