php - 提交订单时Magento没有增加ID

Question

我最近一直在做一个扩展。但是，我遇到了一个障碍，我想知道是否应该重新安装 Magento。我遇到的问题发生在昨天。我相信我已经追根溯源，但我不知道如何解决。当我尝试提交订单时，在第一个订单下达后，出现以下错误:

There was an error processing your order. Please contact us or try 
again later.exception 'PDOException' with message 'SQLSTATE[23000]:

'UNQ_INCREMENT_ID'' in

我尝试的第一件事:我完全禁用了我的扩展程序。所以，这不是我的扩展名，但也许它导致数据库发生了一些变化，从而导致了这种情况。我一直在使用正确的编码方法开发我的扩展(不修改核心文件，并且尽可能地扩展而不是覆盖)。

看起来好像订单的增量ID没有被设置!我回到 Mage_Eav_Model_Entity_Type -> fetchNewIncrementId(第 141 行)，发现它在发现没有增量模型后在第 145 行返回 void:

144: if (!$this->getIncrementModel()) {
145:    return false;
146: }

而且，这是导致问题的 SQL 查询(显然它不是递增 id):

INSERT INTO `sales_flat_order` (`coupon_code`, `protect_code`, `shipping_description`, 
`is_virtual`, `store_id`, `customer_id`, `base_discount_amount`, `base_grand_total`,

'2011-07-19 15:23:28', '1', NULL, '0', '0', '0', '0', '5', '5')

我可以提供任何其他信息来帮助找到解决方案吗？非常感谢!

您是否向销售/订单模型添加了任何属性？在那里，如果您在添加属性 sales/order 时没有指定增量模型，将会丢失它的增量模型。即使您再次关闭扩展程序，这也会保留。

$installer->installEntities(
    'order'    => array(
        'entity_model'        => 'order',
        'table'               => 'sales/order',
        'increment_model'     => 'eav/entity_increment_numeric', //<-- This is important and might have caused the trouble!!!
        'increment_per_store' => true,
        'backend_prefix'      => 'sales_entity/order_attribute_backend',
        'attributes'          => array(
            'my_new_attribute' => array(
            'label'            => 'Omx Gift Certificates',
            'type'             => 'text',
            'global'           => Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_GLOBAL,
            'visible'          => true,
            'required'         => false,
            'user_defined'     => true,
        ),
    )
);

如果这是来源，您可以执行以下操作: 从 sales_flat_order 表中删除添加的列(在本例中为:my_new_attribute)并重新运行扩展的安装程序(当然使用指定的 increment_model...)。
