help in updating the code " Head First Ruby on Rails"

I would like understood routes, scaffolding etc. "Head First Ruby on
Rails" has a very old Rails. I am working with Rails 4. On 93 page "Head
First Ruby on Rails"/polish edition/Helion 2010
there is:
ActionController::Routing::Routes.draw do |map|
map.connect '/ads/:id', :controller=> 'ads', :action=>'show'
map.connect ':controller/:action/:id'
map.conect ':controller/:action/:id.:format'
end

In "Agile Web Development in Rails 4" there is something different
and I do not know, how change to Rails4 the cod of "Head First Ruby on
Rails".
on the 92 page "Agile Web Development in Rails 4 - in English, 2013" is
something like this:
Download rails40/depot_d/config/routes.rb
Depot::Application.routes.draw do
get "store/index"
resources :products

etc...

Could Anybody help me to change/write in Rails4 the mebay.com project's
config/routes.rb?

There's a free course at http://railstutorial.org that goes through the entire process of building a Rails application (and along the way, understanding what Rails is and does and doesn't do).

thank you

Basically since the upgrade to rails 4.

map has been deprecated, instead is more secure to specify the HTTP verb of the route GET, POST, PUT, PATCH, DELETE, also rails use the CRUD structure that stand for Create, Read, Update, Delete, this the basic actions that rails provide inside our controller when doing a scaffold, also Index, New.

So when creating the routes you have to specify a URL, which goes to a controller and an action.

example:

get ‘store/index’, to: ‘store#index’, as: “store”

HTTP URL controller#action name

the name part will give you some helper methods: store_url and store_path. Usually when creating a scaffold it will generate in your routes files a line like this resources :store, which will provide all the routes for that controller.

This is a link explaining everything http://guides.rubyonrails.org/routing.html.

Hope I helped you.

Thank You for response. MB
