ruby on rails 3 - Passing parameters with links -


routes.rb

resources :carts   resources :cart_items end

rake routes:

cart_cart_items   post   /carts/:cart_id/cart_items(.:format)            cart_items#create

when click on link, should create new item in cart_items:

     link_to 'add cart', '#'

assuming have @cart, doing link_to 'add cart', cart_path(@cart) suffice.
