member_collection_routes

🔄 Define Member vs Collection Routes Clearly

Use member for routes acting on a specific resource and collection for those on the whole set. This distinction keeps your URL semantics correct and helpers intuitive.

# config/routes.rb
Rails.application.routes.draw do
  resources :orders do
    member do
      post :cancel    # /orders/:id/cancel
    end

    collection do
      get :recent     # /orders/recent
    end
  end
end

Now you can call cancel_order_path(order) and recent_orders_path, making your intentions explicit.
