Custom routes issue

The url that is generated for an additional controller method is causing some confusion. I have a site where people can enter their email to get access for a beta account. This allows me to later grant each person access manually. To do this I have one additional controller method, activate, to which is given a method by the following:

map.namespace :site do |site|     site.resources :beta_signups, :member => {:activate => :put} end

This provides me with a method:    activate_site_beta_signup_url(1)

that generates urls like the following:    http://localhost:3000/site/beta_signups/1/activate

But when I click on the following link I get an error saying that:    Unknown action    No action responded to 1

What am I missing?

Thanks for the help.

Forget this one.

Maybe it was my lack of coffee, or too much coffee, but I forgot to make the link_to a put request.
