我编写了一个非常小的程序来帮助我学习 ruby​​。以下是我从服务器日志中得到的错误。

这是我从浏览器尝试的 URL，并出现以下错误：localhost:3000/say/hello

这是我的 Gemfile 内容

  gem 'coffee-rails', '~> 3.2.1'
  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

我查看了其他一些 SO 线程，但似乎没有一个与我的问题特别相关。

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动作）

或者

match ':controller(/:action(/:id))(.:format)'这将允许您使用如下代码：link_to "hello", :controller => "mycontroller", :action => "myaction"或输入 URL（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，您的视图应该位于将使用它的控制器名称的子目录中，而不是在实际的“视图”目录中

编辑：

查看下面的答案，您需要将文件设为 html.erb 而不是 rhtml

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

此外，这不遵循 Rails 的宁静规则，因此您可能需要取消注释.match ':controller(/:action(/:id))(.:format)'最后一行的config/routes.rb.
