Ruby on Rails教程/ articles / new

Question

我正在按照本教程http://guides.rubyonrails.org/getting_started.html进行操作 ，位于5.1节中，但是没有找到/ articles / new /的目录。 我应该创建此文件还是应该在向config/routes.rb添加resources :articles时完成此操作？ 我的/config/routes.rb看起来像：

 Rails.application.routes.draw do
  get 'welcome/index'

  # The priority is based upon order of creation: first created -> highest priority.
  # See how all your routes lay out with "rake routes".

  # You can have the root of your site routed with "root"
  root 'welcome#index'
  resources :articles
  # Example of regular route:
  #   get 'products/:id' => 'catalog#view'

  # Example of named route that can be invoked with purchase_url(id: product.id)
  #   get 'products/:id/purchase' => 'catalog#purchase', as: :purchase

  # Example resource route (maps HTTP verbs to controller actions automatically):
  #   resources :products

  # Example resource route with options:
  #   resources :products do
  #     member do
  #       get 'short'
  #       post 'toggle'
  #     end
  #
  #     collection do
  #       get 'sold'
  #     end
  #   end

  # Example resource route with sub-resources:
  #   resources :products do
  #     resources :comments, :sales
  #     resource :seller
  #   end

  # Example resource route with more complex sub-resources:
  #   resources :products do
  #     resources :comments
  #     resources :sales do
  #       get 'recent', on: :collection
  #     end
  #   end

  # Example resource route with concerns:
  #   concern :toggleable do
  #     post 'toggle'
  #   end
  #   resources :posts, concerns: :toggleable
  #   resources :photos, concerns: :toggleable

  # Example resource route within a namespace:
  #   namespace :admin do
  #     # Directs /admin/products/* to Admin::ProductsController
  #     # (app/controllers/admin/products_controller.rb)
  #     resources :products
  #   end
end

提前致谢！

Answer 1

您是否生成了文章控制器？

生成控制器时，它应该在视图中创建一个目录，但其中没有任何erb文件。

Answer 2

您可以手动创建文件，但是最好以rails的方式进行操作，因此您需要生成articles控制器并将所需的视图传递给它 。

举个例子：

rails g controller articles index new show edit

这将创建具有适当的方法供您使用的articles_controller ，以及视图 ，这是rails生成器所做的！

生成器还在route.rb文件中创建了get路由 ，因此请确保删除这些get路由，因为您已经在使用resources :articles处理路由。
