Magento资源模型不工作

我有以下代码：

$recipients = Mage::getResourceModel('crm/crm_collection');
            $recipients->getSelect()
                    ->joinInner(array(
                        'link' => $recipients->getTable('crm/bulkMailLink'),
                    ), "link.crm_id = e.entity_id", array(
                        'link_id' => 'link.id',
                    ))
                    ->where("link.queue_id = ? AND link.sent_at IS NULL", $queue->getId());
            $recipients->addAttributeToSelect('title');
            $recipients->addAttributeToSelect('first_name');
            $recipients->addAttributeToSelect('chinese_name');
            $recipients->addAttributeToSelect('last_name');
            $recipients->addAttributeToSelect('email1');
            $recipients->addAttributeToFilter('email1', array('neq'=>''));
            $recipients->setPageSize(100);
            $recipients->setCurPage(1);

然后记录代码生成的select语句：

$recipients = Mage::getResourceModel('crm/crm_collection');
            $recipients->getSelect()
                    ->joinInner(array(
                        'link' => $recipients->getTable('crm/bulkMailLink'),
                    ), "link.crm_id = e.entity_id", array(
                        'link_id' => 'link.id',
                    ))
                    ->where("link.queue_id = ? AND link.sent_at IS NULL", $queue->getId());
            $recipients->addAttributeToSelect('title');
            $recipients->addAttributeToSelect('first_name');
            $recipients->addAttributeToSelect('chinese_name');
            $recipients->addAttributeToSelect('last_name');
            $recipients->addAttributeToSelect('email1');
            $recipients->addAttributeToFilter('email1', array('neq'=>''));
            $recipients->setPageSize(100);
            $recipients->setCurPage(1);

Mage::log("DEBUG: ".((string)$recipients->getSelect()));

上面生成了一个在phpmyadmin中完美执行的工作sql查询，并返回我期望的结果

$recipients = Mage::getResourceModel('crm/crm_collection');
            $recipients->getSelect()
                    ->joinInner(array(
                        'link' => $recipients->getTable('crm/bulkMailLink'),
                    ), "link.crm_id = e.entity_id", array(
                        'link_id' => 'link.id',
                    ))
                    ->where("link.queue_id = ? AND link.sent_at IS NULL", $queue->getId());
            $recipients->addAttributeToSelect('title');
            $recipients->addAttributeToSelect('first_name');
            $recipients->addAttributeToSelect('chinese_name');
            $recipients->addAttributeToSelect('last_name');
            $recipients->addAttributeToSelect('email1');
            $recipients->addAttributeToFilter('email1', array('neq'=>''));
            $recipients->setPageSize(100);
            $recipients->setCurPage(1);

然后我记录$recipients的计数

$recipients = Mage::getResourceModel('crm/crm_collection');
            $recipients->getSelect()
                    ->joinInner(array(
                        'link' => $recipients->getTable('crm/bulkMailLink'),
                    ), "link.crm_id = e.entity_id", array(
                        'link_id' => 'link.id',
                    ))
                    ->where("link.queue_id = ? AND link.sent_at IS NULL", $queue->getId());
            $recipients->addAttributeToSelect('title');
            $recipients->addAttributeToSelect('first_name');
            $recipients->addAttributeToSelect('chinese_name');
            $recipients->addAttributeToSelect('last_name');
            $recipients->addAttributeToSelect('email1');
            $recipients->addAttributeToFilter('email1', array('neq'=>''));
            $recipients->setPageSize(100);
            $recipients->setCurPage(1);

Mage::log("Loading recipients for queue: {$recipients->count()}");

这就是代码停止的地方。实际上，它甚至不会记录消息。如果我注释掉上面的日志代码并尝试

$recipients = Mage::getResourceModel('crm/crm_collection');
            $recipients->getSelect()
                    ->joinInner(array(
                        'link' => $recipients->getTable('crm/bulkMailLink'),
                    ), "link.crm_id = e.entity_id", array(
                        'link_id' => 'link.id',
                    ))
                    ->where("link.queue_id = ? AND link.sent_at IS NULL", $queue->getId());
            $recipients->addAttributeToSelect('title');
            $recipients->addAttributeToSelect('first_name');
            $recipients->addAttributeToSelect('chinese_name');
            $recipients->addAttributeToSelect('last_name');
            $recipients->addAttributeToSelect('email1');
            $recipients->addAttributeToFilter('email1', array('neq'=>''));
            $recipients->setPageSize(100);
            $recipients->setCurPage(1);

foreach ($recipients as $crm)
{
    var_dump($crm);
    die();
}

它不会进入foreach。解析器将在foreach之前停止

$recipients = Mage::getResourceModel('crm/crm_collection');
            $recipients->getSelect()
                    ->joinInner(array(
                        'link' => $recipients->getTable('crm/bulkMailLink'),
                    ), "link.crm_id = e.entity_id", array(
                        'link_id' => 'link.id',
                    ))
                    ->where("link.queue_id = ? AND link.sent_at IS NULL", $queue->getId());
            $recipients->addAttributeToSelect('title');
            $recipients->addAttributeToSelect('first_name');
            $recipients->addAttributeToSelect('chinese_name');
            $recipients->addAttributeToSelect('last_name');
            $recipients->addAttributeToSelect('email1');
            $recipients->addAttributeToFilter('email1', array('neq'=>''));
            $recipients->setPageSize(100);
            $recipients->setCurPage(1);

最糟糕的是没有打印错误消息。我被卡住了

$recipients = Mage::getResourceModel('crm/crm_collection');
            $recipients->getSelect()
                    ->joinInner(array(
                        'link' => $recipients->getTable('crm/bulkMailLink'),
                    ), "link.crm_id = e.entity_id", array(
                        'link_id' => 'link.id',
                    ))
                    ->where("link.queue_id = ? AND link.sent_at IS NULL", $queue->getId());
            $recipients->addAttributeToSelect('title');
            $recipients->addAttributeToSelect('first_name');
            $recipients->addAttributeToSelect('chinese_name');
            $recipients->addAttributeToSelect('last_name');
            $recipients->addAttributeToSelect('email1');
            $recipients->addAttributeToFilter('email1', array('neq'=>''));
            $recipients->setPageSize(100);
            $recipients->setCurPage(1);

谢谢

无论是

count（）

还是

foreach

操作都会触发集合实际

load（）

，这意味着执行查询，获取结果集，并尝试在集合的模型类实例上将每个结果设置为

\u data

。实现该项后，collection类将尝试通过

addItem（）

将其添加到其内部存储器中

$recipients = Mage::getResourceModel('crm/crm_collection');
            $recipients->getSelect()
                    ->joinInner(array(
                        'link' => $recipients->getTable('crm/bulkMailLink'),
                    ), "link.crm_id = e.entity_id", array(
                        'link_id' => 'link.id',
                    ))
                    ->where("link.queue_id = ? AND link.sent_at IS NULL", $queue->getId());
            $recipients->addAttributeToSelect('title');
            $recipients->addAttributeToSelect('first_name');
            $recipients->addAttributeToSelect('chinese_name');
            $recipients->addAttributeToSelect('last_name');
            $recipients->addAttributeToSelect('email1');
            $recipients->addAttributeToFilter('email1', array('neq'=>''));
            $recipients->setPageSize(100);
            $recipients->setCurPage(1);

我怀疑您的集合显式抛出异常，因为结果集中存在重复的主键；有关逻辑，请参见。暂时将其注释掉以进行测试

$recipients = Mage::getResourceModel('crm/crm_collection');
            $recipients->getSelect()
                    ->joinInner(array(
                        'link' => $recipients->getTable('crm/bulkMailLink'),
                    ), "link.crm_id = e.entity_id", array(
                        'link_id' => 'link.id',
                    ))
                    ->where("link.queue_id = ? AND link.sent_at IS NULL", $queue->getId());
            $recipients->addAttributeToSelect('title');
            $recipients->addAttributeToSelect('first_name');
            $recipients->addAttributeToSelect('chinese_name');
            $recipients->addAttributeToSelect('last_name');
            $recipients->addAttributeToSelect('email1');
            $recipients->addAttributeToFilter('email1', array('neq'=>''));
            $recipients->setPageSize(100);
            $recipients->setCurPage(1);

要解决此问题，请更改您的查询或在您的集合类中本地重写

addItem（）

。

先生，您是个天才！非常感谢你。

                    ), "link.crm_id = e.entity_id", array(
                        'link_id' => 'link.id',
                    ))
