Ruby on Rails测试加载程序失败

Question

我正在尝试运行其他人在Ruby on Rails中编写的一些测试。他们过去但不再通过了。这就是我作为堆栈跟踪获得的内容：

  # The priority is based upon order of creation:

  # Keep in mind you can assign values other than :controller and :action

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

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

  # Sample resource route with options:
  #   resources :products do
  #     member do
  #       get 'short'

  #   end

  # You can have the root of your site routed with "root"
  # just remember to delete public/index.html.
  # root :to => 'welcome#index'

  # See how all your routes lay out with "rake routes"

  # This is a legacy wild controller route that's not recommended for RESTful applications.
  # Note: This route will make all actions in every controller accessible via GET requests.
  # match ':controller(/:action(/:id))(.:format)'

Answer 1

On line 9 of the routes.rb file you posted，您有以下代码：

  root :to => 'displays#show', :page => 1, :tab => Tab.first.id

据我所知，Tab模型没有记录，从而产生零错误，Rails无法找到你想要id的第一条记录。
