Reindex产品属性问题

Question

如果产品属性索引给出这样的错误，我该怎么办：

谁有一些解决方案，如果我截断了一些桌子，也许会对我有所帮助。

Answer 1

我逐步进行了调试，发现了上面给出的痕迹的确切原因。我有自定义的脚本将产品导入到Magento，并且在创建新产品时，脚本将多选择属性值附加到产品上。其中一些产品有两次或多次的选项ID，在索引期间，这将导致某些错误，例如“完整性约束违规”。如果我通过代码描述这一点：

$_product->setSomeMultiselectAttribute(array(option_id_1, option_id_2, option_id_1));
$_product->save();

导入完成后，我进行索引，上面给出的例外将出现。那是我修复错误的方法：

$_product->setSomeMultiselectAttribute(array_unique(array(option_id_1, option_id_2, option_id_1)));

也许这将在以后对某人有所帮助。例外已经消失了。

Answer 2

在大多数情况下，这与flat_catalog表有一个问题有关，该表中的键正在数据库中插入，即主要密钥约束。截断它们确实是一个不错的选择，将清除钥匙，然后您可以将其重新索引。

在mysql中： （请记住，您的平桌子可能具有不同的名称）

TRUNCATE TABLE `catalog_category_flat_store_1`;

然后从AdminPanel或通过终端执行从Magento root Directory执行Reindexing Shell-Script，如下所示：

php shell/indexer.php --reindex catalog_product_flat
