difference between scope and namespace of ruby-on-rails 3 routing

Question

I can't understand what the difference is between a namespace and a scope in the routing of ruby-on-rails 3.

Could someone please explain?

namespace "admin" do
  resources :posts, :comments
end

scope :module => "admin" do
  resources :posts, :comments
end

Answer 1

The difference lies in the paths generated.

The paths are admin_posts_path and admin_comments_path for the namespace, while they are just posts_path and comments_path for the scope.

You can get the same result as a namespace by passing the :name_prefix option to scope.
