title: Ruby on Rails looks for css in assets instead of public/stylesheets
body: <p>I am new to Ruby, using ruby 1.9.2P180 and Rails 3.1.0.rc2</p>
  
  <p>I have "screen.css" in my_app_root/public/stylesheets/screen.css and in my application.html.erb</p>
  
  <pre><code> &lt;%= stylesheet_link_tag 'screen.css', :media =&gt; 'screen' %&gt;
  </code></pre>
  
  <p>according to <a href="http://guides.rubyonrails.org/layouts_and_rendering.html" rel="noreferrer">here</a> it should work but my rails server says:</p>
  
  <blockquote>
    <p>Processing by PagesController#home as HTML
    Rendered pages/home.html.erb within layouts/application (0.0ms)
    Completed 200 OK in 4ms (Views: 3.6ms | ActiveRecord: 0.0ms)</p>
    
    <p>Started GET "/assets/screen.css" for 127.0.0.1 at 2011-06-18 11:27:53 +1200
    Served asset /screen.css - 404 Not Found  (2ms)  (pid 10966)</p>
    
    <p>ActionController::RoutingError (No route matches [GET] "/assets/screen.css"):</p>
  </blockquote>
  
  <p>What am I doing wrong here?</p>
  
  <p>Thanks in advance</p>
