Open in new window


I am trying to do:
puts ActionController::Routing::Routes.draw do |map|
	map.resources :users
end.map(&:to_s).sort

Open in new window


But I keep getting the above error. I am using Rails 3 on OSX.

If you're trying to print out method names for an isolated set of routes, this should get you started:

route_set = ActionDispatch::Routing::RouteSet.new
route_set.draw { |map| map.resources :users }

# Unique names, without the _url nor _path
puts route_set.routes.map(&:name).uniq.compact.sort
