Goal: on a initializer field_error.rb add a .wrong class to <div class="wrapOption">
when there is a validation error.


<% @templates.each do |radio| %>
<div class="wrapOption">
<span class="spanOption"><%= f.radio_button :template_id, radio.id %></span><%= content_tag(:label, radio.title, :class => "labelOption")%>
</div>
<% end %>
