奇怪的Rails 2路由问题

Question

I saw this in a rails 2 vs 3 comparison pdf lecture and I'm not sure what's going on with the preview and archived flags.

post.resources :comments, :member => { :preview => :post }, 
  :collection => { :archived => :get }

Any ideas?

Answer 1

:member => { :preview => :post}

Is establishing another method on the member that would would be accessed like so:

comments/1/preview

and would only be accessible through post.

Similarly, :collection => {:archived => :get} establishes a method for the whole collection, that would be accessed through

comments/archived
