在 Magento 2.1.0 中打开产品页面时出现异常

Question

我已经安装了 Magento 2.1.0。 我尝试在程序中打开每个产品页面之前更新库存状态。

我用来更新股票的代码：

// has $sku and quantity of product now
$stockItem = $this->_stockRegistry->getStockItemBySku($sku);
if($quantity > 0){
    $stockItem->setQty($quantity);
    $stockItem->setIsInStock(true);
}else{
    $stockItem->setQty(0);
    $stockItem->setIsInStock(false);
}
$this->_stockRegistry->updateStockItemBySku($sku, $stockItem);

由于以下异常，我突然无法打开产品页面：
不知道是不是因为产品库存的更新。

#71 {main}

我不知道如何解决这个问题。
所以我在第 74 行找到了文件 AbstractSource.php。

我更改了代码：

//if (isset($options[$value])) {
    //return $options[$value];
//}

// new code here
if (isset($options['value'])) {
    return $options['value'];
}

现在我可以再次打开产品...

但我有两个问题：

1. 如何以正确的方式解决此问题/异常？我想我不能修改文件 AbstractSource.php
2. 如果我使用代码“$option['value']”还有其他问题吗？

非常感谢！！！

Answer 1

您收到的错误与产品页面中的选择元素没有获得正确的选项值或您提供的值不是有效的选项值有关。 从您的代码来看，它似乎来自您使用 setIsInStock 的方式。从 magento 代码块文档中，这应该是合法的，因为 setIsInStock 采用 bool 或 int。但是从 Magento Core 代码示例中，他们使用 int。例如： setIsInStock(1)。 你可以在这里找到一个例子： https://github.com/magento/magento2/blob/2.1.0/dev/tests/api-functional/testsuite/Magento/ConfigurableProduct/Api/CartItemRepositoryTest.php#L220

所以我建议您将参数从布尔值更改为整数：0 用于 false 和 1 用于 true。

如果解决了请告诉我。

其次，我很好奇您为什么首先需要这样做。
