Columbus website design

Adding a rss feed to my Ruby on Rails blog

I built this website from scratch using Ruby on Rails so there is still room for improvement.
Today I decided to add a rss feed to the blog. This can be done pretty simple and I will show you what I did.
First I added a new action to my blog controller.

def rss
    @posts=Post.find(:all, :order=> "id DESC")
    render_without_layout
    @headers["Content-Type"] = "application/xml; charset=utf-8" 
  end

Then I created a new view for the xml file. Here is how the rss.rxml file looks like:

xml.instruct!

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

   xml.title       "kolor-designs articles" 
   xml.link        url_for :only_path => false, :controller => 'blog'
   xml.description "kolor-designs.com: Mostly web related stuff" 

   @posts.each do |article|
     xml.item do
       xml.title       article.title
       xml.link        url_for :only_path => false, :controller => 'blog', 
:action => 'show', :id => article.id
       xml.description truncate(article.body,100)
       xml.guid        url_for :only_path => false, :controller => 'blog', 
:action => 'show', :id => article.id
     end
   end

 end
end

That’s it.
