How to pass a symbol through rails routes specified through 'resources'?

Question

I have this set of routes

  resources :flatfiles do
    collection do
      delete :custom_destroy
    end
  end

And I would like to all of the routes to include :key

E.g. get 'flatfiles/:key' => 'flatfiles#index'

I could specify each route individually (like the get action above), but is there a way to do them all at once?

Answer 1

You can use :path

  resources :flatfiles, path: 'flatfiles/:key' do
    collection do
      delete :custom_destroy
    end
  end

That will prefix all sub routes with :key
