test "should update holder" do
        holder = Holder.create(name: "name",user_id: 10)
        put :update,holder: holder
    assert_redirected_to holder_path(assigns(:holder))
end

当我运行它,我得到以下错误：

但在我的路线我有：

Teacherjoy::Application.routes.draw do
  get "users/new"

  resources :questions
  resources :pages
  resources :holders
  resources :users
  resources :sessions,only: [:new,:create,:destroy]
  root :to => 'pages#home'

  match '/signup',to: 'users#new'
  match '/signin',to: 'sessions#new'
  match '/signout',to: 'sessions#destroy',via: :delete
end

耙路返回：

如果你看耙子路线,显然是一个更新的动作,这是一个放置,在持有者控制器,这是我的测试正在做的,对吧？
