RSS help

I have my rss feed working pefectly but I was wondering if I could limit it to showing just the 5 most recently updated products.

heres how my rss is coded

xml.instruct!

xml.rss "version" => "2.0", "xmlns:dc" => "http://purl.org/dc/elements/ 1.1/" do   xml.channel do

   xml.title "FlashItem products"    xml.link url_for :only_path => false, :controller => 'products'    xml.description "Items advertised on the FlashItems website"

    @products.each do |p|      xml.item do       xml.title(p.item_name)       xml.link(url_for :only_path => false, :controller => 'products',:action => 'show', :id => (p.id))       xml.description(p.description)       xml.guid(url_for :only_path => false, :controller => 'products', :action => 'show', :id => (p.id))       xml.pubDate(p.updated_at)       xml.sellername(p.seller_name)       xml.selleremail(p.seller_email)      end     end   end end

controller

def rss       @products = Product.find(:all, :order=> "item_name")       render :layout => false       end

Not much to do with your rss, just add a :limit => 5 to your
Product.find and order it by updated_at.
