Finding a nested resource's 'parent' object?

Say I have this setup:

class Ticket < ActiveRecord::Base   belongs_to :project end

map.resources :projects do |p|   p.resources :tickets end

How would I go about programatically figuring out that Ticket is nested under Project?

Future reference:

    def get_parent_resource(target_klass, path)       # Convert the requested path into hash form       hash = ActionController::Routing::Routes.recognize_path (path, :method => :get)

      # Loop through path keys and see if any end in '_id' and our kid class belongs_to the associated AR Class       pair = hash.detect{|k, v| k.to_s.ends_with?("_id") && target_klass.columns_hash.has_key?(k.to_s)}

      # Load up the AR class based on the matching path pair       klass = pair[0].to_s[0...-3].classify.constantize

      # Find and return the target parent object       klass.find(pair[1])     end

I'm sure it doesn't work in all cases, but I think it gets pretty close.
