Question

我正在尝试在我的应用中实现类似于Twitter的追随者系统。我正在实施Michael Hartl的Rails教程中解释的Follower系统：

http://ruby.railstutorial.org/chapters/following-users

完成示例后我注意到了一个问题：

转到/ users /（id）/ follow或/ users /（id）/ followers会显示以下错误消息：

Unknown action

The action 'following' could not be found for UsersController

或

Unknown action

The action 'followers' could not be found for UsersController

我对这些错误感到困惑的是，我确实在UsersController中定义了这些操作：

def following
    @title = "Following"
    @user = User.find(params[:id])
    @users = @user.followed_users.paginate(page: params[:page])
    render 'show_follow'
  end

  def followers
    @title = "Followers"
    @user = User.find(params[:id])
    @users = @user.followers.paginate(page: params[:page])
    render 'show_follow'
  end

以下是我的routes.rb文件以防万一：

AppName::Application.routes.draw do

  #get "users/index"

  #get "users/show"



authenticated :user do
    root :to => 'home#index'
  end
  root :to => "home#index"
  devise_for :users
  resources :users do
    member do
      get :following, :followers
    end
  end
  resources :works
  resources :relationships, only: [:create, :destroy]
end

其他信息：我正在使用Devise处理用户身份验证。

FIXED：

问题是在用户控制器中放置了以下和后续操作。

Answer 1

在config/routes.rb中，成员操作必须是每行一个：

resources :users do
  member do
    get :following
    get :followers
  end
end

另见http://guides.rubyonrails.org/routing.html#adding-more-restful-actions

Answer 2

resources :users do
  member do
 get  :following 
 get  :followers
    end

 end

以上路由有效，并分别提供following_user_path和followers_user_path路由
