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

scope is bit complex, but provides more options to fine-tune exactly what you want to do.

scope supports three options: module, path and as. If you see scope with all it options, it will be exactly same as namespace.

In other words, routes generated by

namespace :admin do
  resources :posts
end

is same as

scope module: 'admin', path: 'admin', as: 'admin' do
  resources :posts
end

In other words, we can say that there are no default options for scope as compared to namespace. namespace add all these options by default. Thus using scope, we can more fine tune the routes as required.

If you take a deep look into scope and namespace default behaviour, you will find that scope by default supports only :path option, where as namespace supports three options module, path and as by default.
