Question

我的Team控制器具有名为list_questions的自定义操作，需要获得额外的ID :exercise_id。以下是我尝试这样做的方法：

resources :teams do
  member do
    post :enroll
    post :unenroll
    get 'exercises/:exercise_id/list_questions'
  end
end

但是，我收到以下错误：ArgumentError: Missing :action key on routes definition, please check your routes.

实现这一目标的更好方法是什么？

Answer 1

您收到错误，因为未定义该路线的操作。

尝试这样的事情

resources :teams do
  member do
    post :enroll
    post :unenroll

    get 'list_questions(/exercises/:exercise_id)',
      to: "teams#list_questions",
      as: :list_questions
  end
end

你可以这样建立网址：

list_questions_teams_path(@team, @exercise)

Answer 2

只需遵循您的ressourceful路线方法，如：

resources :teams do
  member do
    post :enroll
    post :unenroll
    resources :exercises do
       member do
         resources :list_questions  
       end
    end 
  end
end

将生成：

        enroll_team POST     /teams/:id/enroll(.:format)                                                    teams#enroll
