title: using i18n with rails 3 problem
body: <p>I've got some form for user registration and want to localize it via locales yml files. Especially errors from validations.</p>
  
  <p>For example, locale file:</p>
  
  <pre><code>tr:
    activerecord:
      errors:
        models:
          user: 
            attributes:
              name:
                blank: "can't be blank"
  </code></pre>
  
  <p>it will return: <code>name can't be blank</code> in errors area:</p>
  
  <pre><code>&lt;% @user.errors.each do |error| -%&gt;
    &lt;p&gt;&lt;%= error %&gt;&lt;/p&gt;
  &lt;% end -%&gt;
  </code></pre>
  
  <p>Next step I want to create is to rename <strong>name</strong> attribute (and others) like that (<strong>this is what don't work</strong>):</p>
  
  <pre><code>tr:
    attributes:
      user:
        name: "Real name"
  </code></pre>
  
  <p>to get this error after validation: <code>Real name can't be blank</code></p>
  
  <p>So where I should locale attribute names to translate them in error messages</p>
