Menu best practices

Hi all,

What are your best practices with menu's in Ruby on Rails?

I have now created a helper that sees if a link is the same as the current page an adds a class "active" to it. The only problem is: a link to "users/new" doesn't work anymore when a guest submits the form and the url becomes: "users/save".

How do you guys/girls deal with that?

Ah, thanks Mark. Looks like a function I could use.

But is that all you use for menu's?
