Polymorphic URLs from script/console?

In my routes.rb, I have:

map.resources :users, :member =>      {:edit_business_card => :get,       :update_business_card => :put }

In a view, I can say

<%= update_business_card_url %>

And from my browser, I can post to http://localhost:3000/users/update_business_card.

But not from script/console:

app.update_business_card_user_url

ActionController::RoutingError: update_business_card_user_url failed to generate from {:controller=>"users", :action=>"update_business_card"} - you may have ambiguous routes, or you may need to supply additional parameters for this route. content_url has the following required parameters: ["users", :id, "update_business_card"] - are they all satisfied?

I don't actually care about doing this from console, but rspec has the same difficulty resolving the route. I'm stumped - url_for is getting the same parameters in each case.
