ActionController::RoutingError (没有路由匹配[GET] "/")与所有页面

Question

在使用Capistrano进行部署之后，我得到了ActionController::RoutingError (No route matches [GET] "/")，其中包含了production.log中的所有页面(请参阅404页)。我可以通过耙看到所有的路线-他们都很好！我现在该怎么办？

Production.log：

Started GET "/" for 79.143.104.251 at 2012-06-24 23:53:06 +0400

问题是，您可能对路由器或模型做了更改，但没有重新启动。要查看这些更改，必须重新启动服务器。
