Question

我写了一个非常小的程序来帮助我学习红宝石。以下是我从服务器日志中获得的错误。

这是我在浏览器中尝试使用的网址，其中包含错误：localhost:3000/say/hello

我已经看了一些其他的SO线程，但似乎没有一个与我的问题有关。

Answer 1

在您的routes.rb中，您需要：

match "say/hello" => "myController#myaction"（用适当的值替换控制器和操作）

或

match ':controller(/:action(/:id))(.:format)'这将允许您使用以下代码：link_to "hello", :controller => "mycontroller", :action => "myaction"或输入网址（例如/ say / hello）

前者是首选方法，因为用户无法访问您不希望他们访问的网址。

此外，您的视图应该位于一个子目录中，该子目录中包含将使用它的控制器的名称，而不是在实际的“views”目录中

编辑：

查看下面的答案，你需要使你的文件成为html.erb而不是rhtml

Answer 2

键入bundle execute rake routes以列出应用程序中的所有路由路径。检查那里是否:controller=>"say", :action=>"hello"。

此外，这并不遵循rails的其他规则，因此您可能需要取消注释match ':controller(/:action(/:id))(.:format)'，config/routes.rb位于{{1}}的最后一行。

没有路线匹配[GET]“/ say / hello”
