更新可配置产品引发关于 UNQ_CATALOG_PRODUCT_SUPER_ATTRIBUTE_PRODUCT_ID_ATTRIBUTE_ID 的完整性约束违规错误

Question

我有以下使用 Magento 模型创建或更新可配置产品的脚本。

// Method to create or update configurable product with configurable options
function createOrUpdateConfigurableProduct($product_data, $configurable_products_data)
{
    // Init product
    $product = Mage::getModel('catalog/product');

    // Load product id by sky
    $product_id = Mage::getModel('catalog/product')
        ->getIdBySku($product_data['sku']);

    // If product already exists
    if ($product_id)
    {
        // Load product
        $product->load($product_id);
    }

    // Set product data
    $product
        ->setTypeId('configurable')
        ->setAttributeSetId(4)
        ->setSku($product_data['sku'])
        ->setName($product_data['name'])
        ->setDescription($product_data['description'])
        ->setShortDescription($product_data['description'])
        ->setMetaTitle($product_data['name'])
        ->setMetaDescription($product_data['description'])
        ->setPrice($product_data['price'])
        ->setTaxClassId(2)
        ->setWebsiteIDs(array(1))
        ->setStatus(Mage_Catalog_Model_Product_Status::STATUS_ENABLED)
        ->setVisibility(Mage_Catalog_Model_Product_Visibility::VISIBILITY_BOTH)
        ->setStockData(array(
            'use_config_manage_stock' => 0,
            'manage_stock'            => 1,
            'is_in_stock'             => ($product_data['qty'] >= 1 ? 1 : 0)
        ));

    // Workout all the attribute ids used
    $used_attribute_ids = array();
    foreach ($configurable_products_data as $product_id => $options) {
        foreach ($options as $option) {
            if (!in_array($option['attribute_id'], $used_attribute_ids)) {
                $used_attribute_ids[] = $option['attribute_id'];
            }
        }
    }

    // Set configurable attributes data
    $product->getTypeInstance()->setUsedProductAttributeIds($used_attribute_ids);
    $configurableAttributesData = $product->getTypeInstance()->getConfigurableAttributesAsArray();
    $product->setCanSaveConfigurableAttributes(true);
    $product->setConfigurableAttributesData($configurableAttributesData);

    // Set configurable products data & save
    $product->setConfigurableProductsData($configurable_products_data);
    $product->save();
}

其中 $configurable_products_data 看起来像这样：

Array
(
    [49] => Array
        (
            [0] => Array
                (
                    [label] => 27 in.
                    [attribute_id] => 155
                    [value_index] => 47
                    [is_percent] => 0
                    [pricing_value] => 210
                )

            [1] => Array
                (
                    [label] => 32L
                    [attribute_id] => 156
                    [value_index] => 50
                    [is_percent] => 0
                    [pricing_value] => 210
                )

        )

    [50] => Array
        (
            [0] => Array
                (
                    [label] => 28 in.
                    [attribute_id] => 155
                    [value_index] => 48
                    [is_percent] => 0
                    [pricing_value] => 210
                )

            [1] => Array
                (
                    [label] => 32L
                    [attribute_id] => 156
                    [value_index] => 50
                    [is_percent] => 0
                    [pricing_value] => 210
                )

        )

    [51] => Array
        (
            [0] => Array
                (
                    [label] => 28 in.
                    [attribute_id] => 155
                    [value_index] => 48
                    [is_percent] => 0
                    [pricing_value] => 210
                )

            [1] => Array
                (
                    [label] => 34L
                    [attribute_id] => 156
                    [value_index] => 51
                    [is_percent] => 0
                    [pricing_value] => 210
                )

        )

)

当此代码运行s 时，首先运行 - 它工作正常并创建可配置产品。但是，在第二个运行上，它似乎无法更新现有的可配置产品，它抛出以下神秘错误消息：

Uncaught exception 'PDOException' with message 'SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '52-155' for key 'UNQ_CATALOG_PRODUCT_SUPER_ATTRIBUTE_PRODUCT_ID_ATTRIBUTE_ID''

有什么想法吗？

以上是tablecatalog_product_super_attributetable的说明。这 table 保持可配置产品和简单产品之间的关系。您收到此错误是因为它试图添加已映射的相同简单项目。如果您想在不指定新的简单 sku 的情况下进行更新，可能的解决方法是从此 table 中删除相应可配置产品 table 的条目。在您的代码中，错误来自行 -

$product->setConfigurableAttributesData($configurableAttributesData);

在更新之前，您可以添加一行检查您的可配置产品是否是新的。

if ( $product_is_new ) {
    $product->setConfigurableAttributesData($configurableAttributesData);
}
