I have a Ruby on Rails online marketplace that is broken up into "categories". I want to be able to create RSS Feeds for each category, every time a new listing is added.
The RSS should pull the listing's name and then provide a shortened hyperlink to that listing.
I'm a beginner in Ruby on Rails, what approach should I use to obtain this RS feed and how can I obtain a page's hyperlink, shorten it and integrate it into the feed?
