I''ve just implemented some CSS tabs into my application (from here:
http://labs.silverorange.com/archives/2004/may/updatedsimple), but to display
properly it requires that at least one item in the list is <span> rather
than a
normal link, which I managed using this helper from leapingfrogs.com:
def link_to_unless_current_with_current_class(*args)
link_to_unless_current(*args) {|name|
"<span>#{name}</span>"}
end
(which goes in module ApplicationHelper, if you fancy trying this yourself). It
works perfectly but when you move onto a subitem the rails helper acts properly
and makes your menu tab back into a link, spoiling the formatting.
What I''m looking for is an easy means of keeping the link to the
controller as
text, regardless of which action is being accessed. I think this is possible
using something like link_to_unless (:controller = current controller...) but
I''m not sure of the formatting. Can anyone please help?
Thanks in advance.

Can anyone please help?Wow, thanks for the link to the tabs. I had some poor tabs before I saw them. Here''s how you can do this: module ApplicationHelper def link_to_unless_current_controller(controller_class, *args) link_to_unless(controller.kind_of?(controller_class), *args) do |name| "<span>#{name}</span>" end end end In the view <% # List of all the controllers here. [ PostController, AuthorController, Admin::AuthorsController ].each do |c_class| %> <li> <% c_human_name = c_class.name.demodulize[0..-11].underscore.humanize %> <%= link_to_unless_current_controller(c_class, c_human_name, { :controller => ''/'' + c_class.controller_path }) %> </li> <% end %> Regards, Blair -- Blair Zajac, Ph.D. <blair-szbw9MROnEZWk0Htik3J/w@public.gmane.org> Subversion and Orca training and consulting http://www.orcaware.com/svn/

It run without an error, but simply never produces a span instead of a link, so I guess the condition isn''t firing. Also, is there a way to test if something is a controller without needing the full controller name? What''s the simplest method of finding the current controller? Thanks again.

You did change the list of controller classes, right?> Also, is there a way to test if something is a controller > without needing the full controller name? What''s the simplest method > of finding the current controller?You can check if something is a controller via object.instance_of?(ApplicationController). But you should not need this, as you should know the class of your variables. The current controller is always in ''controller'' in your views and actions. Regards, Blair

In any case, here''s the code I used in the end. I removed the method I added to the helper, as the code was not needed here: <div id="header"> <ul id="primary"> <% [ PostController, Admin::AuthorsController ].each do |c_class| %> <li> <% c_human_name = c_class.name.demodulize[0..-11].underscore.humanize %> <% if controller.kind_of?(c_class) %> <% action_name = controller.action_name.to_sym %> <span> <%= c_human_name %> </span> <ul id="secondary"> <li> <% if [ :index, :list ].include?(action_name) %> <span>List</span> <% else %> <%= link_to ''List'', :action => :list %> <% end %> </li> <li> <% if :new == action_name %> <span>New</span> <% else %> <%= link_to ''New'', :action => :new %> <% end %> </li> </ul> <% else %> <%= link_to c_human_name, { :controller => ''/'' + c_class.controller_path } %> <% end %> </li> <% end %> </ul> </div> Regards, Blair
