我正在从正在创建的应用程序中收到路由错误消息

Question

我在我的get '/favorites', to: 'favorites#index'中包含了config/routes.rb，但出现错误，但我不确定是否是问题所在

ActionController::RoutingError (uninitialized constant FavoritesController):

这是错误消息的一半，我选择不发布整个内容，因为它对于堆栈溢出可能太长了

Answer 1

似乎您尚未创建FavoritesController类。创建app/controllers/favorites_controller.rb并使用索引动作定义控制器。假设您有一个收藏夹模型类，则可以执行以下操作：

Answer 2

假设您有控制器，如果将以下内容添加到路由文件中，错误是否会消失？您可以运行“耙路”并发布输出吗？
