ruby-on-rails – Rails 4：没有路由匹配 – 缺少id密钥的关系问

No route matches {:action=>"show",:controller=>"stocks",:stockpile_id=>#<Stock id: 17,stockpile_id: 3,code: "rttrtrt",name: "",description: "",quantity: nil,cost_pence: nil,information: "",created_at: "2013-08-18 19:52:46",updated_at: "2013-08-18 19:52:46">,:id=>nil,:format=>nil} missing required keys: [:id]

访问以下网址时：/ admin / stockpiles / 3 / stocks /

我的路线看起来像：

scope '/admin' do
  root :to => 'admin#index',:as => 'admin'
  resources :stockpiles,:companies

  scope :path => 'stockpiles/:stockpile_id' do
    resources :stocks
  end
end

错误消息中包含的数据：

id | stockpile_id |   code   | name | description | quantity | cost_pence | information |         created_at         |         updated_at         
17 |            3 | rttrtrt  |      |             |          |            |             | 2013-08-18 19:52:46.856864 | 2013-08-18 19:52:46.856864

我的库存模型：

class Stock < ActiveRecord::Base
  belongs_to :stockpile
end

Stockpile模型没有什么有趣的,只是它有很多股票..

这是我的控制器：

class StocksController < ApplicationController
  before_action :set_stock,only: [:show,:edit,:update,:destroy]

  def index
    @stockpile = Stockpile.find(params[:stockpile_id]) 
    @stocks = @stockpile.stocks.all 
  end

  def show
  end

  def new
    @stockpile = Stockpile.find(params[:stockpile_id])
    @stock = @stockpile.stocks.new
  end

  def edit
  end

  def create
    @stockpile = Stockpile.find(params[:stockpile_id])
    @stock = @stockpile.stocks.new(stock_params)

    if @stock.save
      redirect_to @stock,notice: 'Stock was successfully created.'
    else
      render action: 'new'
    end
  end

  def update
    if @stock.update(stock_params)
      redirect_to @stock,notice: 'Stock was successfully updated.'
    else
      render action: 'edit'
    end
  end

  def destroy
    @stock.destroy
    redirect_to stocks_url,notice: 'Stock was successfully destroyed.'
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_stock
      @stockpile = Stockpile.find(params[:stockpile_id])
      @stock = @stockpile.stocks.find(params[:id])
    end

    # Only allow a trusted parameter "white list" through.
    def stock_params
      params.require(:stock).permit(:code,:name,:description,:quantity,:cost_pence,:information)
    end
end

以下是有问题的观点：

<div class="page-header">
  <%= link_to new_stock_path(params[:stockpile_id]),:class => 'btn btn-primary' do %>
    <i class="icon-plus icon-white"></i>
    New Stock
  <% end %>
  <h1>Listing stocks</h1>
</div>

<table class="table table-bordered table-striped">
  <thead>
    <tr>
      <th>Stockpile</th>
      <th>Code</th>
      <th>Name</th>
      <th>Description</th>
      <th>Quantity</th>
      <th>Cost pence</th>
      <th>Information</th>
      <th></th>
      <th></th>
      <th></th>
    </tr>
  </thead>

  <tbody>
<% @stocks.each do |stock| %>
    <tr>
      <td><%= stock.stockpile %></td>
      <td><%= stock.code %></td>
      <td><%= stock.name %></td>
      <td><%= stock.description %></td>
      <td><%= stock.quantity %></td>
      <td><%= stock.cost_pence %></td>
      <td><%= stock.information %></td>
      <td><%= link_to 'Show',stock %></td>
      <td><%= link_to 'Edit',edit_stock_path(stock) %></td>
      <td><%= link_to 'Destroy',stock,confirm: 'Are you sure?',method: :delete %></td>
    </tr>
<% end %>
  </tbody>
</table>

帮助将非常感激 – 看起来像奇怪的东西正在发生因为stockpile_id似乎设置为库存,似乎没有股票参数或任何东西 – 所以我们得到了缺少的id错误.

谢谢.
