嵌套资源路由问题

Question

这可能很简单，但是我已经有一段时间没有接触过rails了，我不确定自3.2以来是否发生了这么大的变化

所以我有两个模型，报表和收据。每个报表都有许多收据，因此我的模型如下所示：

class Report < ActiveRecord::Base

    has_many :receipts, :dependent => :destroy
  accepts_nested_attributes_for :receipts, :allow_destroy => true

    attr_protected :id

end
class Receipt < ActiveRecord::Base
    belongs_to :report

    attr_protected :id

    validates_presence_of :vendor, :date, :description, :amount, :acctCode
end

我的收据控制器位于控制器文件夹的根目录中，列出了所有的操作(它是由scaffold生成的)

我的路线有：

root :to => "index#index"

resources :reports do
    resources :receipts
end

我的link_to是这样的：

<%= link_to 'New Receipt', new_report_receipt_path, :class=>"btn btn-success" %>

这给了我一个错误：

No route matches {:action=>"new", :controller=>"receipts"}

我运行了rake路径，得到了以下结果：

     report_receipts GET    /reports/:report_id/receipts(.:format)          receipts#index
                     POST   /reports/:report_id/receipts(.:format)          receipts#create
  new_report_receipt GET    /reports/:report_id/receipts/new(.:format)      receipts#new
 edit_report_receipt GET    /reports/:report_id/receipts/:id/edit(.:format) receipts#edit
      report_receipt GET    /reports/:report_id/receipts/:id(.:format)      receipts#show
                     PUT    /reports/:report_id/receipts/:id(.:format)      receipts#update
                     DELETE /reports/:report_id/receipts/:id(.:format)      receipts#destroy

怎么回事？

Answer 1

您只是忘记了在您的路由中提供报告id。这取决于您在视图中访问报表的方式，但它必须类似于：new_report_receipt_path(@report)

Answer 2

这不应该是：

new_report_receipts_path

？请注意s，即

link_to‘新收据’，new_report_receipts_path，:class=>"btn btn-success"
