Rails - Sep 2005 - Conditional Menu in View = How do you create handle this scenario ?

Hi all,

<NewbieAlert>

I''m just working on this site with a main_nav menu that should  
highlight the active section on each request. This code worked  
perfectly when I had all the sections as methods in [ /app/ 
controllers/application.rb ], but not when I began transforming some  
sections [ skills, clients, portfolio ] to their own controllers.

I guess I should use something like [  if @params[:controller] =~ / 
^<controller_name>/  ] to test for each of the controllers, but that  
seems to unsophisticated for Ruby/Rails, so I''m hoping there''s
a
smarter way. Is there ?


   def main_nav
     # temporary array of possible menu items
     menus = %w{ home experience skills clients portfolio contact }
     nav = String.new
     nav << "<ul class=\"leftNav\">\n"
     menus.each do |menu|
       if controller.action_name.downcase == menu.downcase
         nav << "<li><a href=\"#\"
class=\"active\">#{menu.capitalize}
</a></li>\n"
       else
         if menu.downcase == ''home''
           nav << "<li><a
href=\"/\">#{menu.capitalize}</a></li>\n"
         else
           nav << "<li><a
href=\"/#{menu.downcase}/\">#
{menu.capitalize}</a></li>\n"
         end
       end
     end
     nav << "</ul>\n"
   end

</NewbieAlert>


Kind regards,

Mats
