Parameter :requirements in routing doesn't use implicit anchors

Reported by Harm Aarts | September 24th, 2009 @ 10:22 AM

Consider the following route:
map.detail "subscription_plans/:provider/:plan", :action =>
"detail", :requirements => {:plan => /[^ ]+/}

I want this route to match any string without a space character. So
"Telfort-100" matches "Telfort 100" does not. This however does not work. It matches both.

I believed this to be correct but it's not. Including anchors ('\A'
'$' etc) is not allowed and the docs seem to suggest they are implicit.

The problem you're having is that the space is url encoded as %20 or + when the router compares the regexp. If you change your requirement to explicitly state what is allowed then your route will work. These regexps /[-_a-zA-Z0-9]+/ or /\w+/ both prevent spaces in the url.
