是的，我一直在努力解决这个路由问题。
我有一个名为snippet的嵌套评论部分，这个为belongs_to：books
请参阅我的管理员索引，代码段控制器＆amp;按顺序排列的路线，我刚刚实施了浅层资源。

无法找到ID = 2
的图书
只有一本书，它有很多片段，但我认为它试图寻找片段ID，而不是关于批准行动的书。我不明白为什么？

尝试运行get controller#action，而不是match 'controller#action'
get "books/:id/activate" => "books#approve", :as => "active_book"
get "/snippets/:id/activate" => "snippets#approve", :as => "active_snippet"
