Rails 3.2 路由：错误地将父资源路由到嵌套资源中的子资源控制器

Question

我完全被难住了——查看了所有嵌套资源问题，但找不到答案。

有嵌套资源，我试图通过 new_user_path（父资源）获取一个 link_to 以显示新用户页面，但 rails 想要路由到子资源 (simple_products_configs) 控制器而不是父资源控制器。

有人知道我做错了什么以及如何解决吗？会不会是视图文件中带有 simple_form 的东西？

错误信息：

Routing Error

检查 Users 控制器 是否正确设置，new controller 操作和其他 REST 控制器操作是否正确设置..
