【发布时间】：2016-03-13 06:24:06
【问题描述】：

我可以一次添加到购物车，但是刷新页面后，购物车是空的。我正在使用 Spree 2.4。

点击“添加到购物车”后，我在订单控制器#edit 中检查@order 的值：

[1] pry(#<Spree::OrdersController>)> @order
=> #<Spree::Order id: 5, number: "R017142307", item_total: #<BigDecimal:89a8e10,'0.5E1',9(27)>, total: #<BigDecimal:89a8d20,'0.5E1',9(27)>, state: "cart", adjustment_total: #<BigDecimal:89a8bb8,'0.0',9(27)>, user_id: 1, completed_at: nil, bill_address_id: nil, ship_address_id: nil, payment_total: #<BigDecimal:89a8898,'0.0',9(27)>, shipping_method_id: nil, shipment_state: nil, payment_state: nil, email: "spree@example.com", special_instructions: nil, created_at: "2016-03-13 05:41:55", updated_at: "2016-03-13 06:18:01", currency: "USD", last_ip_address: "192.168.1.108", created_by_id: 1, shipment_total: #<BigDecimal:897bc80,'0.0',9(27)>, additional_tax_total: #<BigDecimal:897bb90,'0.0',9(27)>, promo_total: #<BigDecimal:897baa0,'0.0',9(27)>, channel: "spree", included_tax_total: #<BigDecimal:897b938,'0.0',9(27)>, item_count: 1, approver_id: nil, approved_at: nil, confirmation_delivered: false, considered_risky: false, guest_token: "kRau34G-dOY0Sh06Mk0_4g", canceled_at: nil, canceler_id: nil, store_id: 1, state_lock_version: 0>

还有line_items：

[3] pry(#<Spree::OrdersController>)> @order.line_items
=> [#<Spree::LineItem id: 21, variant_id: 7, order_id: 5, quantity: 1, price: #<BigDecimal:88e8480,'0.5E1',9(27)>, created_at: "2016-03-13 06:18:01", updated_at: "2016-03-13 06:18:01", currency: "USD", cost_price: #<BigDecimal:88e78a0,'0.17E2',9(27)>, tax_category_id: 1, adjustment_total: #<BigDecimal:88e7738,'0.0',9(27)>, additional_tax_total: #<BigDecimal:88e7648,'0.0',9(27)>, promo_total: #<BigDecimal:88e7558,'0.0',9(27)>, included_tax_total: #<BigDecimal:88e7468,'0.0',9(27)>, pre_tax_amount: #<BigDecimal:88e7378,'0.0',9(27)>>]

视图加载并且购物车看起来正常。但是，我刷新后，它说购物车是空的..

@order 还是一样，但是 line_items 消失了：

[1] pry(#<Spree::OrdersController>)> @order
=> #<Spree::Order id: 5, number: "R017142307", item_total: #<BigDecimal:d3bfeb8,'0.5E1',9(27)>, total: #<BigDecimal:d3bfdc8,'0.5E1',9(27)>, state: "cart", adjustment_total: #<BigDecimal:d3bfc60,'0.0',9(27)>, user_id: 1, completed_at: nil, bill_address_id: nil, ship_address_id: nil, payment_total: #<BigDecimal:d3bf968,'0.0',9(27)>, shipping_method_id: nil, shipment_state: nil, payment_state: nil, email: "spree@example.com", special_instructions: nil, created_at: "2016-03-13 05:41:55", updated_at: "2016-03-13 06:18:01", currency: "USD", last_ip_address: "192.168.1.108", created_by_id: 1, shipment_total: #<BigDecimal:d3beb80,'0.0',9(27)>, additional_tax_total: #<BigDecimal:d3bea90,'0.0',9(27)>, promo_total: #<BigDecimal:d3be9a0,'0.0',9(27)>, channel: "spree", included_tax_total: #<BigDecimal:d3be838,'0.0',9(27)>, item_count: 1, approver_id: nil, approved_at: nil, confirmation_delivered: false, considered_risky: false, guest_token: "kRau34G-dOY0Sh06Mk0_4g", canceled_at: nil, canceler_id: nil, store_id: 1, state_lock_version: 0>

[2] pry(#<Spree::OrdersController>)> @order.line_items
=> []

我无法追踪 line_items 的填充位置。有人可以帮忙吗？谢谢。

编辑：

我在 GET "/cart" 中 POST 到 /orders/populate/ 后的日志中看到了 DELETE：

【问题讨论】：

我认为这不是你的错。这是狂欢问题。页面刷新时购物车变空。
奇怪。您是否看到添加到购物车时正在运行的 sql 查询以及稍后在刷新时运行？将产品添加到购物车后，您能否立即在管理员中查看订单内容？
@Jakub 我可以在添加到购物车后立即在管理员中看到订单。它处于“购物车”状态，但是当我转到订单“购物车”链接时，它说订单是空的。我可以看到很多 sql 查询。我应该发布吗？
你能看到通过`INSERT INTO "spree_line_items" ("cost_price", "created_at", "currency", "order_id", "price", "quantity", "tax_category_id", " updated_at", "variant_id") 值 (?, ?, ?, ?, ?, ?, ?, ?, ?) [["cost_price", 17.0], ["created_at", "2016-03-13 22:02 :09.040804"], ["currency", "USD"], ["order_id", 5], ["price", 55.0], ["quantity", 1], ["tax_category_id", 1], ["updated_at ", "2016-03-13 22:02:09.040804"], ["variant_id", 30]]` 查询？您可以在数据库客户端中直接选择吗？只是想知道问题出在哪里。是 DB 相关还是 Spree。
@Jakub 我认为这不是数据库问题，因为在我刷新购物车页面后有一条 DELETE 语句。出于某种原因，它正在删除订单项。

【解决方案1】：

似乎您正在使用gem 'spree_active_sale'，这是造成这种行为的罪魁祸首。它有一个 before_filter 从订单中销毁不活动的产品线项目。见https://github.com/suryart/spree_active_sale/blob/master/app/controllers/spree/orders_controller_decorator.rb#L3。
