title: How to use Twitter-Bootstrap hover popover with Rails
body: <p>I am a newbie with rails, I want to use the Twitter-Bootstrap hover popover in my rails app.
  I have the following part:</p>
  
  <pre><code>&lt;div class="field"&gt;
      &lt;%= f.label :first_name, {:class =&gt; 'label'}%&gt;&amp;nbsp;
      &lt;%= f.text_field :first_name ,{:class =&gt; 'span3',}%&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>If the user hover on the <code>:first_name</code> label, a message appear telling him something. But I don't know where to put things in my app like the js files reference or the function.</p>
  
  <p>I tried this <a href="https://stackoverflow.com/questions/8659890/twitter-bootstrap-popover-function-not-working-in-rails">example</a> and put the <code>javascript_include_tag</code> in the layout/application.html.erb</p>
  
  <p>But seems that I don't know how to get it works. So I need a detailed description about how to use it.</p>
