What's the Rails 4 equivalent of this routing?

So I'm trying to follow this: http://web.archive.org/web/20120315004343/http://webtempest.com/sortable-list-in-ruby-on-rails-3-almost-unobtrusive-jquery

And the routing done here is: 

resources :books do
    post :sort, on: :collection
    # ruby 1.8 would go :on => :collection
end

What does post :sort, on: :collection mean here, and what would be the Rails 4 equivalent?

resources :books by itself gives you the CRUD routes.

post :sort by itself gives you a POST route /sort to the sort action.

on: :collection means that the action is for the whole collection (books/sort), unlike member which applies to each book (books/:id/sort). The index route is a collection route while show is a member route.

The syntax change from :on => :collection is exactly the same as on: :collection when using Ruby 1.9 or greater (as pointed out in the comments). I prefer to use the new syntax because it looks cleaner but it is not required. Both are valid in a Rails 4 app as long as you're using Ruby 1.9 or greater
