does debug exist for routes URL creation? to identify why I'm having problem with some of my URL being generated

Hi,

Does anyone know of any tricks to get some sort of “DEBUG” happening for that shows the rails process of generating URL’s
(i.e. noting I’ve got many routes specified)?

So then I could click a link on my web page and as the view generates the URL’s there would be some useful debug out of rails to indicate for each URL generated, how it matches against the routes, which pattern was choosen etc.

Tks
Greg
