如何使用 PDOException 错误修复 magento 重新索引？

Question

重新索引数据时出现错误。我已经为这个问题工作了大约 3 天，仍然找不到解决方案。这是我收到的日志错误：

默认值 (MANAdev) 索引进程未知错误：异常 带有消息“SQLSTATE [23000]”的“PDOException”：完整性约束 违规：1452 无法添加或更新子行：外键 约束失败（glasseso_magento.m_filter2_value, CONSTRAINT FK_m_filter2_value_mana_db?edit_session 外键 (edit_session_id) 参考文献m_edit_session (id) 删除 CASCADE ON UPDATE CASCAD)' 在 /Applications/MAMP/htdocs/magestore/lib/Zend/Db/Statement/Pdo.php:228

下一个异常

希望有人能在这个问题上帮助我。

Answer 1

一个快速的解决方案是捕获异常并记录它，这样索引器就可以完成它的工作。

也许 try{} catch{} 块适合这里：

Applications/MAMP/htdocs/magestore/app/code/local/Mana/Db/Helper/Data.php(217)：Mage_Core_Model_Abstract->save()

异常的原因可能在 Mana-Module 的不一致实现中找到。

Answer 2

一个好的解决方案可能是禁用“外键检查”。在文件 /app/code/local/Mana/Db/Helper/Data.php (217) ...

改变这个：

$object->save();

为此：

$resource = Mage::getSingleton('core/resource');
$writeConnection = $resource->getConnection('core_write');
$writeConnection->query("SET FOREIGN_KEY_CHECKS = 0;");
$object->save();
$writeConnection->query("SET FOREIGN_KEY_CHECKS = 1;");

祝你好运！

Answer 3

我看了一下m_edit_session的内容，只有一行ID为1，created_at下面有时间戳。我将唯一一行的 ID 更改为 0（而不是 1），这个错误就消失了。
