ruby-on-rails - 没有路由匹配 [GET] "/app1"

Question

Rails.root:/home/chris/rails_projects/app1

我收到有关路线的消息。我的 routes.rb 文件显示:

我完全不知道如何处理这个问题。我在 Virtualbox 中使用 Ubuntu 12.04。

Rails.application.routes.draw 做

  # 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'

  # 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

您需要创建一个 Controller 和一个 View 来将您的应用定向到某个地方。

然后您需要通过编辑路由文件将您的应用路由到该操作。例如，您可以取消注释行:

 root 'welcome#index'

这将意味着当您导航到位于根目录 (/app1) 的站点根目录时，将转到欢迎 Controller 及其索引操作。
