title: Rails truncate with a 'read more' toggle
body: <p>I have a paragraph that I want truncated with the option of clicking "read more" and have it slide open with the rest of the content.  The content is coming from a database field.  Here's what I have for the truncate: </p>
  
  <pre><code>&lt;%= truncate(@major.glance, :length =&gt; 250, :omission =&gt; '... Read More')%&gt;
  </code></pre>
  
  <p>I can't seem to find a way to do this with data pulled from a database.  I see a lot of examples using the full text with the text you want to hide in a separate div tag.  But, since this content is coming from a database and is dynamic I can't find any information on how to do it.  </p>
