        if url_string =~ /^\w+:\/\//
          url_string == "#{request.protocol}#{request.host_with_port}#{request.request_uri}"

current_action? and current_controller?

qoobaa · Jan 2, 20093 thanks

I use them in link_unless_current_controller helper.

def current_action?(options)
url_string = CGI.escapeHTML(url_for(options))
params = ActionController::Routing::Routes.recognize_path(url_string, :method => :get)
params[:controller] == @controller.controller_name && params[:action] == @controller.action_name
end

def current_controller?(options)
url_string = CGI.escapeHTML(url_for(options))
params = ActionController::Routing::Routes.recognize_path(url_string, :method => :get)
params[:controller] == @controller.controller_name
end

You should also have a look at https://github.com/twg/active_link_to if you need an 'active' class on your links.
