Rails在错误的位置发送id

Question

我有一个名为prattachments的控制器，它在purchase_requests中有一个restful路由，但当我尝试在each_with_index块中使用它发送删除请求时：

link_to "delete", purchase_request_prattachment_path(attachment), :method=>:delete

根据rake routes，此路线应为：

purchase_request_prattachment DELETE /purchase_requests/:purchase_request_id/prattachments/:id {:action=>"destroy", :controller=>"prattachments"}

然而，当它被调用时它会反转：purchase_request和：id，有人知道如何修复它吗？

Answer 1

呼叫路径应该是：

purchase_request_prattachment_path(purchase_request, attachment)
