ruby-on-rails – Rails购物车 – 不添加当前订单

我正在构建一个基本的购物车,它之前的工作非常好.没有改变任何代码(我git reset – 硬到我工作的上一次提交)它就破了. (？！？)这是细分：

Github Repo：https://github.com/christinecha/michaka

>创建产品. ?
>将产品ID添加到新订单项. ?
>将订单项添加到订单. ?

可能的问题

！ – 在创建订单商品时,新订单将继续创建=购物车始终为空.

！ – 购物车未连接到正确的订单ID

！ – 正在触发新会话=新订单=问题

订购项目控制器

class OrderItemsController < ApplicationController
  def create
    @order = current_order
    @order_item = @order.order_items.new(order_item_params)
    @order.save
    session[:order_id] = @order.id
  end

  def update
    @order = current_order
    @order_item = @order.order_items.find(params[:id])
    @order_item.update_attributes(order_item_params)
    @order_items = @order.order_items
  end

  def destroy
    @order = current_order
    @order_item = @order.order_items.find(params[:id])
    @order_item.destroy
    @order_items = @order.order_items
  end
private
  def order_item_params
    params.require(:order_item).permit(:quantity,:product_id)
  end
end

SESSION_STORE.RB

Rails.application.config.session_store :cookie_store,key: '_bead-project_session'

订购模型

class Order < ActiveRecord::Base
  belongs_to :order_status
  has_many :order_items
  before_create :set_order_status
  before_save :update_subtotal

  def subtotal
    order_items.collect { |oi| oi.valid? ? (oi.quantity * oi.unit_price) : 0 }.sum
  end

  def subtotal_cents
    subtotal * 100
  end


private
  def set_order_status
    self.order_status_id = 1
  end

  def update_subtotal
    self[:subtotal] = subtotal
  end

end

应用控制器

class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception
  helper_method :current_order

  def current_order
    if !session[:order_id].nil?
      Order.find(session[:order_id])
    else
      Order.new
    end
  end
end
