如何控制关系查询的顺序

Question

Symfony/doctrine 中名为 JosVmOrderHistory 的模型有什么魔力吗？

我有这个 schema.yml 摘录：

JosVmOrder:
  tableName: jos_vm_orders
  columns:
    order_id: { type: integer(4), primary: true, autoincrement: true }
    user_id: { type: integer(4), notnull: true }
    vendor_id: { type: integer(4), notnull: true }
    order_number: { type: string(32), notnull: false }
    user_info_id: { type: string(32), notnull: false }
    order_total: { type: 'decimal(15, 5)', notnull: true }
    order_subtotal: { type: 'decimal(15, 5)', notnull: false }
    order_tax: { type: 'decimal(10, 2)', notnull: false }
    order_tax_details: { type: string(), notnull: true }
    order_shipping: { type: 'decimal(10, 2)', notnull: false }
    order_shipping_tax: { type: 'decimal(10, 2)', notnull: false }
    coupon_discount: { type: 'decimal(12, 2)', notnull: true }
    coupon_code: { type: string(32), notnull: false }
    order_discount: { type: 'decimal(12, 2)', notnull: true }
    order_currency: { type: string(16), notnull: false }
    order_status: { type: string(1), notnull: false }
    cdate: { type: integer(4), notnull: false }
    mdate: { type: integer(4), notnull: false }
    ship_method_id: { type: string(255), notnull: false }
    customer_note: { type: string(), notnull: true }
    ip_address: { type: string(15), notnull: true }
  relations:
    User: { class: JosUser, local: user_id, foreignAlias: OrderList }
    LatestVmOrderDetail: { class: LatestVmOrderDetail, local: order_id, foreign: order_id }

JosVmOrderHistory:
  tableName: jos_vm_order_history
  columns:
    order_status_history_id: { type: integer(4),primary: true, autoincrement: true }
    order_id: { type: integer(4) }
    order_status_code: { type: string(1) }
    date_added: { type: timestamp(25) }
    customer_notified: { type: integer(4), notnull: false }
    comments: { type: clob(16777777), notnull: false }
  relations:
    Order: { class: JosVmOrder, local: order_id, foreign: order_id }
    OrderStatus: { class: JosVmOrderStatus, local: order_status_code, foreign: order_status_code }

首先，JosVmOrderHistory 的foreignAlias 是“JosVmOrderHistory”，而不是我所假设的“JosVmOrderHistoryList”。

其次，在 model/doctrine/Order.class.php 中，我有以下函数：

function getPaymentStatus(){

    $historyList = $this->getJosVmOrderHistory();
    if (count($historyList)){

        return $paymentStatus = $historyList[0];
    }else{
        return $paymentStatus = null;
    }
}

$historyList 始终按 order_status_history_id 的降序排列。我什至添加到 model/doctrine/JosVmOrderHistoryTable.class.php:

public function createQuery($alias){

    return parent::createQuery($alias)->orderBy('order_status_history_id asc');


}

但它保持降序排列..

编辑：我已经更新了主题 - 这个问题似乎归结为如何控制关系查询的 OrderBy。 createQuery 似乎根本没有被调用。

如果出于速度原因需要此功能，如果您只对第一个订单感兴趣，则不应从数据库加载整个订单历史记录，而应使用如下查询：

function getPaymentStatus(){

    $historyList = Doctrine::getTable('JosVmOrderHistory')->createQuery()->where('order_id = ?', $this->order_id)->orderBy('order_status_history_id')->limit(1)->execute();
    if (count($historyList)){

        return $paymentStatus = $historyList[0];
    }else{
        return $paymentStatus = null;
    }
}

话虽如此，有可能会像您以前那样自动影响排序试图通过使用监听器来做到这一点。过去，我创建了一个通用排序行为，您可以使用它，例如：

  actAs:
    DefaultSort: { column: title }
