编程创建信用备忘录

Question

给定一个已发票的订单（通过交货现金进行测试）并且正在处于“处理”状态，我该如何为给定的SKU和数量创建信用备忘录（以Magento路由以外的代码中； /test.php)?

说我的订单有SKU "100-0055-BRO-S" 和数量 2, ，我想退还其中的1。我当前的代码看起来像这样：

require 'app/Mage.php';
umask(0);
Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);
setlocale(LC_MONETARY, 'en_US');

$order = Mage::getModel('sales/order')->loadByIncrementId(1117575);
$convertor = Mage::getModel('sales/convert_order');

$refundSku = '100-0055-BRO-S';
$refundQty = 1;
$refundOi = null;
//$refundInvoice = null;

foreach($order->getAllItems() as $oi) {
    if($oi->getSku() == $refundSku) {
        $refundOi = Mage::getModel('sales/order_item')->load($oi->getId());
        break;
    }
}

$mcm = $convertor->toCreditmemo($order);
$mcmi = $convertor->itemToCreditmemoItem($refundOi);
$mcmi->setQty($refundQty);

$mcmi->setDiscountAmount($refundOi->getDiscountAmount() * ($mcmi->getQty() / $mcmi->getOrderItem()->getQtyOrdered()));
$mcmi->setBaseDiscountAmount($refundOi->getBaseDiscountAmount() * ($mcmi->getQty() / $mcmi->getOrderItem()->getQtyOrdered()));
$mcmi->setTaxAmount($refundOi->getTaxAmount() * ($mcmi->getQty() / $mcmi->getOrderItem()->getQtyOrdered()));
$mcmi->setBaseTaxAmount($refundOi->getBaseTaxAmount() * ($mcmi->getQty() / $mcmi->getOrderItem()->getQtyOrdered()));
$mcmi->setHiddenTaxAmount($refundOi->getHiddenTaxAmount() * ($mcmi->getQty() / $mcmi->getOrderItem()->getQtyOrdered()));
$mcmi->setBaseHiddenTaxAmount($refundOi->getBaseHiddenTaxAmount() * ($mcmi->getQty() / $mcmi->getOrderItem()->getQtyOrdered()));

$mcm->addItem($mcmi);
$mcm->register();

Mage::getModel('core/resource_transaction')
    ->addObject($mcm)
    ->addObject($mcm->getOrder())
    ->save();

这导致在订单上创建信贷备忘录并显示在管理面板中。但是，该项目看起来像这样：

Price    Qty  Subtotal   Tax Amount   Discount Amount    Row Total
$38.00    1    $0.00       $1.62           $19.00         -$17.39

我不明白为什么小计为0。也许它与不使用发票有关？但是我不确定该如何处理。似乎正在取折扣金额并从小计 +税额中减去。同样，所有信贷备忘录总计（小计，调整退款，调整费，税收，总计）为0.00美元。

我正在手动设置值的数学 $mcmi （法师信贷备忘录）似乎是粗略的。我认为，鉴于我将其设置为数量，Magento会为我设置这些东西，但似乎并非如此，所以我必须自己做。如果有更好的方法来设置这些价值，我也很感谢那里的帮助。

而不是直接使用转换器，最好使用订单服务模型：

Mage::app('admin');

$order = Mage::getModel('sales/order')->loadByIncrementId('1117575');
$orderItem = $order->getItemsCollection()->getItemByColumnValue('sku', '100-0055-BRO-S');
$service = Mage::getModel('sales/service_order', $order);
$data = array(
    'qtys' => array(
        $orderItem->getId() => 1
    )
);
$creditMemo = $service->prepareCreditmemo($data)->register()->save();

至少到目前为止，这对我来说很好。

如果您需要在线退款，则应以这种方式使用：

$order = Mage::getModel('sales/order')->loadByIncrementId('1117575');
$service = Mage::getModel('sales/service_order', $order);

$creditmemo = $service->prepareInvoiceCreditmemo($invoice);
$creditmemo->setRefundRequested(true)
    ->setOfflineRequested(false) // request to refund online
    ->register();

Mage::getModel('core/resource_transaction')
    ->addObject($creditmemo)
    ->addObject($creditmemo->getOrder())
    ->addObject($creditmemo->getInvoice())
    ->save();
