undefined method `locales_for_column and translatable_columns

[meetme2meat]

It seem that the method mention is resulting in undefined method

<% translatable_columns.each do |column| %>
     <div class="field">
       <%= f.label "#{column}_#{I18n.locale}" %><br />
       <%= f.text_field "#{column}_#{I18n.locale}" %>
     </div>  
 <%end%>

 <% locales_for_column(:name) do |locale| %>
  <p>
    <%= form.label "name_#{locale}" %>
    <%= form.text_field "name_#{locale}" %>
  </p>
<% end %>

Any idea why i'm using on app stack on rails 3.2.1 and ruby-1.9.2

Sorry I didn't reply until now. Didn't get a notification mail for some reason.

We had bad documentation for that code. Sorry! It should be YourModel.locales_for_column(:name).each. Similarly for translatable_columns.
