Hi! my question is simple, the answer, i don’t know… Given this in  
routes.rb:

ActionController::Routing::Routes.draw do |map|  
map.resources :zones do |zone|  
zone.resources :customers  
end  
end

If i’m “standing” on CustomersController, how can i inspect  
ActionController::Routing::Routes to know that ZonesController is the  
controller for my parent resource?

Thank you.

I have found a way to store resource information

$auto\_rest\_resources= []

class ActionController::Resources::Resource  
alias\_method :initialize\_before\_auto\_rest, :initialize

def initialize \*args  
initialize\_before\_auto\_rest(\*args)  
$auto\_rest\_resources \<\< self  
end  
end

is there any better way to do this?
