Behold, the nav_link:

The nav_link helper works just like the standard Rails link_to helper, but adds a 'selected' class to your link (or its wrapper) if certain criteria are met. By default, if the link's destination url is the same url as the url of the current page, a default class of 'selected' is added to the link.

<%= nav_link 'My Page', my_path %>

When my_path is the same as the current page url, this outputs:

<a class="selected" href="http://example.com/page">My Page</a>

For more options and full usage details, see: http://viget.com/extend/rails-selected-nav-link-helper

Drop nav_link_helper.rb into app/helpers in your Rails 3.x app and enjoy.

UPDATE: Now with block support!

Same usage as link_to:

<%= nav_link 'http://example.com/page' do %>
  <strong>My Page</strong>
<% end %>
