Ruby on rails 当前页面？具有不同控制器和操作的方法

我正在使用

current\u page？

方法将“active”附加到围绕我的导航链接的li标签上<代码>当前页面？还允许我处理子菜单中的活动链接。侧边栏中有指向整个应用程序中不同控制器和操作的链接。但是，单击侧栏中的最后一个链接（链接以编辑贷方注册路径）时，我收到以下错误：

没有路由匹配{:action=>“dashboard”， ：controller=>“贷方/贷方账户”}

我不确定它从哪里获得

：controller=>“贷方/贷方账户”

。我没有在任何if语句中指定该控制器

My_sidebar.html.erb：
