执行cron时发生PDO异常：新闻稿队列发送失败（“字段列表”中的未知列“ main_table.data”）

处理新闻通讯队列时，cron作业失败。我调试了PDO调用，似乎Magento在这里混淆了各个字段。我不知道Magento（或Zend PDO）从何处选择字段，但看起来完全混淆了：

Magento似乎无法获得客户的名字。最后选择是：

SELECT eav_entity_type.* FROM eav_entity_type WHERE (eav_entity_type.entity_type_code='customer')

DESCRIBE customer_eav_attribute

DESCRIBE customer_eav_attribute_website

然后出现带有不存在的字段列表的选择：

SELECT main_table.data, main_table.lifetime, main_table.expire, main_table.priority, additional_table.attribute_id, additional_table.is_visible, additional_table.input_filter, additional_table.multiline_count, additional_table.validate_rules, additional_table.is_system, additional_table.sort_order, additional_table.data_model, scope_table.website_id AS scope_website_id, scope_table.is_visible AS scope_is_visible, scope_table.multiline_count AS scope_multiline_count FROM eav_attribute AS main_table INNER JOIN customer_eav_attribute AS additional_table ON additional_table.attribute_id = main_table.attribute_id LEFT JOIN customer_eav_attribute_website AS scope_table ON scope_table.attribute_id = main_table.attribute_id AND scope_table.website_id = :scope_website_id WHERE (main_table.entity_type_id = :mt_entity_type_id)

该查询的参数：:mt_entity_type_id' => 1和:scope_website_id' => 0

这引起了

exception 'PDOException' with message 'SQLSTATE[42S22]: Column not found: 1054 Unknown column 'main_table.data' in 'field list''

因为eav_attribute表不包含字段数据，生存期，到期或优先级。

这是完整的堆栈跟踪：

一切正常，直到Mage_Customer_Model_Customer->getAttribute('firstname')通话。

我们没有扩展客户模型或使用任何这样做的模块，因此预览新闻稿的效果还不错，也可以手动发送，因此只有在Magento尝试通过cron调用处理新闻稿队列时，才会发生此异常。

我认为您已经修改了核心文件app / code / core / Mage / Newsletter / Model / Resource / Subscriber / Collection.php

请检查第130行附近的showCustomerInfo（）函数。它应该是：

public function showCustomerInfo()
{
    $adapter = $this->getConnection();
    $customer = Mage::getModel('customer/customer');
    $firstname  = $customer->getAttribute('firstname');
    $lastname   = $customer->getAttribute('lastname');

    $this->getSelect()
        ->joinLeft(
            array('customer_lastname_table'=>$lastname->getBackend()->getTable()),
            $adapter->quoteInto('customer_lastname_table.entity_id=main_table.customer_id
             AND customer_lastname_table.attribute_id = ?', (int)$lastname->getAttributeId()),
            array('customer_lastname'=>'value')
        )
        ->joinLeft(
            array('customer_firstname_table'=>$firstname->getBackend()->getTable()),
            $adapter->quoteInto('customer_firstname_table.entity_id=main_table.customer_id
             AND customer_firstname_table.attribute_id = ?', (int)$firstname->getAttributeId()),
            array('customer_firstname'=>'value')
        );

    return $this;
}

我为什么这么认为？

1. 您的错误日志显示不涉及任何第三方扩展名或Mage /本地文件。

2. 此Magento操作的标准SQL查询没有“ main_table.data，main_table.lifetime，main_table.expire，main_table.priority”部分。

在堆栈跟踪中运行，SQL应该如下所示：

SELECT `main_table`.`attribute_id`, `main_table`.`entity_type_id`, `main_table`.`attribute_code`, `main_table`.`attribute_model`, `main_table`.`backend_model`, `main_table`.`backend_type`, `main_table`.`backend_table`, `main_table`.`frontend_model`, `main_table`.`frontend_input`, `main_table`.`frontend_label`, `main_table`.`frontend_class`, `main_table`.`source_model`, `main_table`.`is_required`, `main_table`.`is_user_defined`, `main_table`.`default_value`, `main_table`.`is_unique`, `main_table`.`note`, `additional_table`.`is_visible`, `additional_table`.`input_filter`, `additional_table`.`multiline_count`, `additional_table`.`validate_rules`, `additional_table`.`is_system`, `additional_table`.`sort_order`, `additional_table`.`data_model`, `scope_table`.`website_id` AS `scope_website_id`, `scope_table`.`is_visible` AS `scope_is_visible`, `scope_table`.`is_required` AS `scope_is_required`, `scope_table`.`default_value` AS `scope_default_value`, `scope_table`.`multiline_count` AS `scope_multiline_count` FROM `eav_attribute` AS `main_table`
 INNER JOIN `customer_eav_attribute` AS `additional_table` ON additional_table.attribute_id = main_table.attribute_id
 LEFT JOIN `customer_eav_attribute_website` AS `scope_table` ON scope_table.attribute_id = main_table.attribute_id AND scope_table.website_id = :scope_website_id WHERE (main_table.entity_type_id = :mt_entity_type_id)

我似乎无法在Magento的任何地方找到未知的列，但是我偷偷摸摸地认为这与会话/缓存有关，但不是100％肯定。您是否启用了Redis？如果是这样，请禁用并清除缓存并查看结果。
