所以我使用以下代码加载了一系列产品:
$magento_time= 'some time string';
$collection = Mage::getModel('catalog/product')->getCollection();
$collection->addFieldToFilter(array(
array('attribute'=> 'updated_at', 'gt'=> date('Y-m-d H:i:s', strtotime($magento_time))),
));
$collection->save();
在保存时收到此错误:

如何将产品加载到集合后将其保存回数据库?

更改以下内容对我有用:
Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);
foreach ($collection as $entry) {
$entry->save();
}

请注意,自我2年前第一次提出这个问题以来,Magento API发生了重大变化 - 这个答案可能不再适用。

你做一个foreach并逐个保存元素。
