<% form_for location do |location_form| %>
<ul class="location">
<li><%= location_form.label location.section %></li>
<li><%= location_form.label location.sub_section %></li>
<li><%= location_form.label location.place_holder %></li>
</ul>
<div class="content-area">
<% location.versions.each do |version| %>
<div class="content" >
<% location_form.fields_for version do |version_form| %>
<%= version_form.label version.environment %>
<%= version_form.text_area :content %>
<% end %>
</div>
<% end %>

<% end %>
#controller
