我希望有人能帮助我。我收到以下问题:
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 URL 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
我的库存型号:
class Stock < ActiveRecord::Base
belongs_to :stockpile
end
库存模型没有什么有趣的,只是它有很多库存。
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
这是有问题的观点:
<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>
非常感谢您的帮助-看起来有些奇怪,因为 stockpile_id 似乎设置为库存,并且似乎没有库存参数或任何东西-因此我们收到了缺少 id 错误。
谢谢。
