title: Rails I18n Errors
body: <p>I am reading <a href="http://edgeguides.rubyonrails.org/i18n.html#translationsfor-active-recordmodels" rel="nofollow">I18N for Active Record Models</a> but I can't get an attribute on my model to display correctly.</p>
  
  <p>I have a model like this:</p>
  
  <pre><code>class Tran &lt; ActiveRecord::Base
      validates :description, :presence =&gt; true,
                              :length =&gt; {:maximum =&gt; 100 }
  end
  </code></pre>
  
  <p>and a en.yml file like this:</p>
  
  <pre><code>en:
    activerecord:
      attributes:
        tran:
          description: "Description"
      errors:
        models:
          tran:
            attributes:
              description:
    errors:
      messages:
        blank: "can't be blank!"
  </code></pre>
  
  <p>When I show the error message on the client, the "can't be blank!" successfully shows up, but the description does not change to "Description" like I would expect.  What am I doing wrong?</p>
  
  <p>Thanks.</p>
