title: Rails paperclip plugin
body: <p>I am a newbie. I am trying to upload an image through paperclip. The url and path code is working but the style option is not working. This is my code:</p>
  
  <pre><code>class User &lt; ActiveRecord::Base
    has_attached_file   :image, :styles =&gt; { :small =&gt; "150x150&gt;" },
                        :url  =&gt; "/assets/users/:id/:style/:basename.:extension",
                        :path =&gt; ":rails_root/public/assets/users/:id/:style/:basename.:extension"
  end
  </code></pre>
  
  <p>When I use the style it doesn't work. If I remove the style option it does work. Please help me out!</p>
