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         


        

Answer 1

from the rails guide

"The namespace scope will automatically add :as as well as :module and :path prefixes."

so

namespace "admin" do
  resources :contexts
end

is the same as

scope "/admin", as: "admin", module: "admin" do
  resources :contexts
end
