[Beginning Rails 3] Listing 2-4. The config/routes.rb file

routes.rb

Hello::Application.routes.draw do |map|
  match ':controller(/:action(/:id(.:format)))'
end

Isso não funciona mais no rails 4. Dá uma olhada nesse link: http://stackoverflow.com/a/19722929/405013

Hello rbarazi,
I am learning rails and I am using "beginning rails 4 3rd edition". I am sill on the basic "hello world" and at first the code in the book for the routes.rb didn't work. rails server wasn't able to launch. I read the message and I figured out that the error was in the routes.rd file so instead of your code, I inserted the code below:
Rails.application.routes.draw do
get':controller(/:action(/:id(.:format)))'
end
I am on mac I would like know why the ones you provide didnt work.
Thanks

Hi @ansaanch, If you're using Rails 4, you can do the following:

get 'salutation/hello'
