重新索引数据时出错。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：

希望有人能在这个问题上帮助我。
我查看了m_edit_session的内容，只有一行ID为1，created_at下有一个时间戳。我将唯一一行的ID更改为0（而不是1），这个错误就消失了。
一个好的解决方案可以是禁用"外键检查"。在文件/app/code/local/Mana/Db/Helper/Data.php（217）中。。。
更改此项：
$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！
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（）
异常的原因可能是Mana模块的执行不一致。
