Disabling links to current page in Layouts

Hello,

I was wondering how I can control the navigation links in a layout to
not show a link to the current page/action.

I have a layout with a navigation area that has links to various
actions. I do not want the link to the current page/action to be
visible.
I know I can create a different template for each actions - but how
Un-DRY. So is there a way for the template to know which action/page we
are on and then use that information to decide what to show - like in
PHP? Code examples are always helpful.

Thanks in advance --K

tell me where to look

check out http://api.rubyonrails.com/classes/ActionView/Helpers/UrlHelper.html#M000382

In views you can also use controller.controller_name, controller.action_name

link_to_unless_current(name, options = {}, html_options = {}, *parameters_for_method_reference, &block)

Creates a link tag of the given name using an URL created by the set of options, unless the current request uri is the same as the links, in which case only the name is returned (or the given block is yielded, if one exists). This is useful for creating link bars where you dont want to link to the page currently being viewed.

Or for more customization link_to_if or link_to_unless....
