Difference between member and collection of rails routes.rb

Differences between members and collections in routes.rb

I will describe the difference between member and collection when setting the routing in routes.rb of rails.

For menber

`routes.rb`


resources :buy_additional_actions, only: %i[] do
   member do
      get 'index' => 'buy_additional_actions#index'

In the case of menber,: id is automatically added to the generated url.

buy_additional_action GET　/buy_additional_actions/:id/index(.:format)　buy_additional_actions#index

For collection

`routes.rb`


resources :buy_additional_actions, only: %i[] do
   collection do
      get 'index' => 'buy_additional_actions#index'

In the case of collection,: id is not added to url.

buy_additional_actions GET　/buy_additional_actions/index(.:format)　buy_additional_actions#index
