title: Use Rails ERB tag in Helper
body: <p>Using Rails 4. I have the following:</p>
  
  <pre><code>module ShopsHelper
    def edit_shop(shop)
      link_to edit_shop_path(shop), target: "_blank" do
        raw("&lt;i class='fa fa-edit'&gt;&lt;/i&gt; Update")
      end
    end
  end
  </code></pre>
  
  <p>Note that I use <code>&lt;i class='fa fa-edit'&gt;&lt;/i&gt;</code> which is for Font Awesome, but <a href="http://%20github.com/FortAwesome/font-awesome-sass" rel="nofollow">Font Awesome gem</a> provides the <code>&lt;%= icon "edit" %&gt;</code> which is cleaner. How can I use the <code>icon</code> tag in the helper?</p>
