php - Magento 模型保存方法更新记录而不是插入

Question

我有一个图像 ID 数组，我正在对其进行迭代以将它们插入到数据库表“slider_images”中。下面是代码片段:

        try {
            $sliderImages= Mage::getModel('gallery/sliderImage')->getCollection()
                ->addFieldToFilter('slider_id', array('eq' => $sliderId));

            $sliderImageIds = array_column($sliderImages->getData(), 'gallery_image_id');

            $addImageIds = array_diff($galleryImageIds,$sliderImageIds);
            $deleteImageIds = array_diff($sliderImageIds, $galleryImageIds);

            foreach ($addImageIds as $addImageId) {
                $sliderImageData = array();
                $sliderImageModel = Mage::getModel('gallery/sliderImage');

                $sliderImageData['slider_id'] = $sliderId;
                $sliderImageData['gallery_image_id'] = $addImageId;

                $sliderImageModel->addData($sliderImageData)->save();
            }

            foreach ($deleteImageIds as $deleteImageId) {
                $deleteSliderImageModel = Mage::getModel('gallery/sliderImage');
                $deleteSliderImageModel->setGalleryImageId($deleteImageId)->delete();
            }

            $this->_getSession()->addSuccess(
                $this->__('Total of %d record(s) were successfully updated', count($galleryImageIds))
            );
        }catch (Exception $e) {
            $this->_getSession()->addError($e->getMessage());
        }

这里的$addImageIds是一个图片id数组:

Array ( [0] => 1 [2] => 2 )

问题:这里是更新一条记录，而不是插入一条新记录。如果我检查查询日志

UPDATE `slider_images` SET `gallery_image_id` = '1' WHERE (slider_id='11')

UPDATE `slider_images` SET `gallery_image_id` = '2' WHERE (slider_id='11')

表结构如下

我想插入这些值而不是更新。

感谢任何帮助。

在save方法循环后调用$sliderImageModel->unsetData();

更新 更改如下代码:

unset($sliderImages);
foreach ($addImageIds as $addImageId) {
    $sliderImageData = array();
    $sliderImageModel = Mage::getModel('gallery/sliderImage');

    $sliderImageData['slider_id'] = $sliderId;
    $sliderImageData['gallery_image_id'] = $addImageId;

    $sliderImageModel->addData($sliderImageData)->save();
    $sliderImageModel->unsetData();
    unset($sliderImageModel);
}
