With nested routes does the parent controller or the child controller process the request for the "new" action?

Question

If you have a nested resource defined like this:

map.resources :magazines, :has_many => :ads.

for these models:

class Magazine < ActiveRecord::Base 
  has_many :ads 
end 

class Ad < ActiveRecord::Base 
  belongs_to :magazine 
end

When you invoke this url:

/magazines/1/ads/1/new

with the nested route helper:

new_magazine_ad_path

Which controller handles this new action: the magazines controller or the ads controller?

Answer 1

Might want to read through section 3.8 on the routing guide but if I am correct (and as the guide suggests) it is the Ads controller.

Answer 2

You can use rake routes to see a list of all your routes including their names where applicable.
