I am new to Rails. I found it very strange when I use the resources in routes.rb, after I redirect the page to controller/index, it render the controller/show .
I know GET controller/action is same as match "controller/action", :to => "controller/action"
I think the strange thing happens to me about the redirect, is similar to the GET and Match.
so I wonder what exactly the resources mean, can I use some simple match do the same thing?
resources is a shortcut for generating seven routes needed for a REST interface.
resources :widgets is equivalent to writing
get "widgets" => "widgets#index", :as => 'widgets'
get "widgets/:id" => "widgets#show", :as => 'widget'
get "widgets/new" => "widgets#new", :as => 'new_widget'
post "widgets" => "widgets#create", :as => 'widgets'
get "widgets/:id/edit" => "widgets#edit", :as => 'edit_widget'
patch "widgets/:id" => "widgets#update", :as => 'widget'
put "widgets/:id" => "widgets#update", :as => 'widget'
delete "widgets/:id" => "widgets#destroy", :as => 'widget'
it just saves you the trouble.
By the way, get is not exactly the same as match. get, post, put and delete are shortcuts for limiting the route to a single HTTP verb. The two route definitions below are equivalent.
match 'foo' => 'controller#action', :method => :get
get 'foo' => 'controller#action'
