Ruby on Rails routes.rb

Question

This question has probably been answered multiple times but I am trying to understand the concept and since I am completely new to Ruby on Rails I am hoping someone can explain it to me.

I'm following a tutorial to create a small twitter post app and its asked me to put the following in the route.rb file and run WEBrick to see if its working.

ActionController::Routing::Routes.draw do |map|
  map.resources :posts
  map.connect ':controller/:action/:id'
  map.connect ':controller/:action/:id.:format'
end

The problem with that is as soon as I run "rails server" the server starts and after a few seconds exits and give this

..RubyProjects/twitter/config/routes.rb:57:in `block in ': uninitialized constant ActionDispatch::Routing::Routes (NameError)...

a lot of other errors but I suspect they are all being created by the one above. I am running Ruby 1.9.3p429 and Rails 4.0.0.rc2.

Whiel I was searching for a solution i did realize that this might be caused because I am using syntax from an earlier version which has changed in Rails 4 but I cannot figure out what the correct syntax would be for the new version.

What would the syntax be for a newer version be in this instance?

Answer 1

Do it like this:-

<yourprojectname>::Application.routes.draw do
resources :products
  match ':controller(/:action(/:id))(.:format)'
end

Answer 2

get ':controller(/:action(/:id(.:format)))'

将此优先级最低的行（最后一行）写入config/routes.rb文件。
