RoutingError没有与[GET] "/stories“匹配的路由

Question

操作系统: openSUSE 11.4 Rails 3.2.0

我刚刚创建了一个非常简单的应用程序"koko“。下面是我运行的命令的顺序

rails new koko
rails generate model Story name:string description:string
rake db:migrate
rails generate controller Stories index

以上所有命令均已成功执行。然后我运行=>rails服务器来启动服务器。localhost:3000/工作正常。

当我尝试执行localhost:3000/store时，我得到以下错误：(浏览器显示第一行关于没有路由匹配)

Answer 1

您的问题是，您正在尝试使用非RESTful资源的RESTful接口。您创建了一个模型，并创建了一个带有索引操作的控制器(/controller_name/action)。

如果您对使用/stories/index感到满意，那么我们就完成了！如果您更喜欢更传统的RESTful界面/stories，那么我建议您使用：

rails generate resource ModelName fields:types。

这将创建一个Model和一个Controller，并且应该可以开箱即用。这将设置评论中提到的路由。

希望这能有所帮助！

Answer 2

您可能只是遇到了一些命名问题。通常，在创建控制器时，它应该是

rails g controller stories index

或

rails g controller Story index

然后将自动生成的路由更改为

match "/stories" => "stories#index", :as => "stories"
