title: Ruby on Rails: current_page? problem when using actions
body: <p>I'm now implementing navigation tabs for my Rails application.
  I would like to generate different CSS and html for current tab (add id="current" and do not
  link the title) - basic stuff. </p>
  
  <p>I found the function: <strong>current_page?</strong> but unfortunately it doesn't work in a way i would expect:</p>
  
  <p>When I call: current_page?(:controller => "bank_account") it returns true for /bank_account but not for /bank_account/soem_action</p>
  
  <p>Is there a way to force <strong>current_page?</strong> to return true in this case? So when I don't specify the action it should return true for all the actions of the given controller. </p>
