Rails从嵌套资源中删除记录

Question

我有一个Charge模型，它是Quotes模型的一个子集。

resources :quotes do
  resources :charges
end

我想在报价的编辑页面上删除charge。

报价/ _form.html.haml

- @quote.charges.each do |charge|
  %tr
    %td
      = link_to 'x', charge, :confirm => 'Are you sure you want to delete this charge?', :method => :delete

当我加载页面时，我得到＃＆lt;＃：0x0000012f8a2ea8＆gt;的未定义方法`charge_path'。我也试过了：

= link_to 'x', quote_charge_path(charge), :confirm => 'Are you sure you want to delete this charge?', :method => :delete

这似乎有效，但似乎引号ID和费用ID的顺序错误。例如，生成的网址为<a href="/quotes/11/charges/13" ...它应该是/quotes/13/charges/11。谁知道如何正确地做到这一点？感谢。

更新

有趣的是，最终工作的是= link_to '×', [@quote, charge], :confirm => 'Are you sure you want to delete this charge?', :method => :delete, :class => "close"。当我指定路径quote_charge_path([@quote, charge])时，它正在创建错误的URL。不知道为什么......

对于嵌套路由助手，您需要传入父对象和子对象。尝试

quote_charge_path([@quote, charge])
