定义具有附加标识的自定义路由

Question

我的Team控制器需要自定义动作list_questions需要接收额外的编号:exercise_id。下面是我怎么想这样做：

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

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

有什么更好的方式来实现这一目标？

Answer 1

您正在收到错误，因为该路线的操作未定义。

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 

，你可以建立的网址是这样的：

list_questions_teams_path(@team, @exercise) 

Answer 2

只想跟着你ressourceful路线接近，如：

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

将产生：

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