Hello, I've got the following model

objectA 1 <------> 0..* objectB 0..* <-------> 1 objectC

I'd like the url GET /objectA/1/objectC to show all objectC associated with objectA through objectB

In routes.rb map.resources :objectAs, :has_many => [:objectCs] or map.resources :objectAs do |:objectA| objectA.resources :objectCs end

shows me all objectCs not just those associated with objectA through objectB

How can I get all objectCs associated with objectA using the url GET / objectA/1/objectC? Also if I had the following model objectA 0..* <-------> 0..* objectC How can I get all objectCs associated with objectA using the url GET / objectA/1/objectC?

Thanks, ewan
