I have a navigation menu that contains a link per controller in my application. This menu is the same for all controllers, but I want this behaviour: <a>Users</a> <span>Statistics</span> and <span>Users</span> <a>Statistics</a> depending on the page you''re currently on. I''ve put a <render :partial => "_menu"> in the layout/application.rhtml file that is used as layout for all views. And in every view map, I then define a _menu.rhtml partial. This is of course not flexible enough, since when I want to change some name, I have to make changes in all these files. What is a better way? -- Posted via http://www.ruby-forum.com/.

You may want to try something like this:
<%= link_to_unless_current("Users",
:action=>''users'') %>
<%= link_to_unless_current("Statistics",
:action=>''statistics'' ) %>

One more question, I used the temporary variable controller_name because I will need it in a lot of links. Should it be a regular variable or an instance variable? -- Posted via http://www.ruby-forum.com/.
