我对 Rails 比较陌生，最近设法断开了指向我的一个模型内容的链接......

之前在 stackoverflow 上发布了一个问题，我调整了to_param模型中的函数，以便将产品名称附加到产品 ID。

我所做的更改是：

在products.rb,

def to_param
  "#{id}-#{product_name.parameterize}"  
end

在routes.rb,

match '/:id' => 'uniquewetsuits#show'

这成功地创建了我希望的地址/products/ID-product-name，但是，我收到一条错误消息，指出没有带有 的产品ID=ID-product-name。

如果我导航到/products/ID，我可以正常成功地查看该页面。

任何人都可以告诉我如何重新连接事物，以便我得到更长的 ID 字符串的匹配项吗？

谢谢你的时间
