Rails对View if-end语句的注释使Linux / Apache / FastCGI上的渲染更加混乱

Question

the following code does work under my Windows development environment, but not on my production Linux/Apache2/FastCGI env.

in my view rhtml file :

<td id='first_column' class='column'>
       <% content_for :head do #DO NOT CACHE THIS content for : HEAD %>
            <%= stylesheet_link_tag('live_tree') %>
            <%= javascript_include_tag "live_tree" %>
       <%  end #content_for %>
       <div  id='contentpanel_13B'>
              <div id='category_howtos_container'>
                    <%= render :partial => 'howtos_for_category'%>
              </div>
       </div>
       <% cache('category_gadget'+I18n.locale.to_s) do %>
           <div class='main_container gadget' id='categories_container'> 
               <%= render :partial => 'categories' %> 
           </div>
       <% end %>
</td>

This code does not render the div contentpanel_13B under linux... I isolated the problem to the comment on this line :

             <%  end #content_for %>

I tried under Rails 2.3.2 and 2.3.3 without success... any hints?

Answer 1

It could be the comment is preventing the '%>' from being parsed

Try putting the comment on its own line

<%  end 
    #content_for 
%>

Answer 2

I got same issue with <% cache(...) do %> some cached html <% end # some comment %> block and putting comment on its own line didn't work for me. I had to do : <% cache do(...) %> some cached html % end %><% some comment %>
