Rails routing: add a custom route to the standard list of actions

Rails routes create the 7 CRUD actions by default following REST.

resources :users

However, I have a confirm_destroy action that I use in almost every resource, because I have a lot of logic that goes on the confirmation page; it's not just a simple yes/no alert dialog.

resources :users do
  get :confirm_destroy, on: :member
end

With 50+ resources, it gets tedious to write this out for each resource and my routes file is literally 3x longer because of this.

Is there any way to add an action to the standard 7 for the resources block such that

resources :users

would be the same as

resources :users do
  get :confirm_destroy, on: :member
end

and I can use it in the routes as a standard action, ie:

resources :users, only: [:show, :confirm_destroy, :destroy]

resources :users, except: [:confirm_destroy]
routes rest ruby-on-rails

While not quite as elegant as you might like, the Rails way would be to use a routing concern, as @dbugger suggested.

For example:

concern :confirmable do
  get 'confirm_destroy', on: :member
end

resources :users, :widgets, concerns: :confirmable
