Rails 5 删除目录名称后编辑和销毁的嵌套路由错误
Rails 5 nested routing error for edit and destroy after removing directory names
我为我的应用程序设置了模型位置、类别、子类别和产品的嵌套路由。我通过附加 , path: ' ' to each route 删除了目录路径，就像我为我的页面模型和根路径所做的那样。该应用程序运行完美，除非我单击编辑并销毁链接。我收到的错误是 can't find record with friendly id: "edit"
旁注，我知道大多数人不同意嵌套 4 深，但这样做是出于一个非常具体的原因，所以我得到了固定的 url 模式，搜索引擎将对其进行索引和排名。如何删除目录并保留编辑？

好吧，如果您真的想要保留您的格式，如何：

base = "locations/:location_id"
['category','subcategory','product'].each do |seg|
get "#{base}/#{seg.pluralize}", to: "#{seg.pluralize}#index", as: seg.pluralize

所以，这样做让我觉得很脏，但这是通过为编辑和新方法添加另一组路由来实现的。
