谷歌购物Magento错误：

我已经在Magento 1.7.0.2商店中安装并配置了Mage_Google购物模块。尝试向Google Shopping添加产品时，/var/log/system.log显示以下错误：

这个问题已经在Magento论坛上被报道了好几次，但是我还没有找到解决这个问题的方法

权限绝对没有问题。这些文件不存在。

谷歌购物模块尝试“动态”加载所有所需属性的属性模型。如果Mage/GoogleShopping/model/Attributes/中不存在此模型。。。发生错误

要覆盖类“Mage\u GoogleShopping\u Model\u Type”中的方法“\u createAttribute”，请为我修复它：

 /**
 * Create attribute instance using attribute's name
 *
 * @param string $name
 * @return Mage_GoogleShopping_Model_Attribute
 */
protected function _createAttribute($name)
{
    $modelName = 'googleshopping/attribute_' . $this->_prepareModelName($name);
    $useDefault = false;

    $className = Mage::app()->getConfig()->getModelClassName($modelName);

    if (class_exists($className)) {
        $attributeModel = Mage::getModel($modelName);
        $useDefault = !$attributeModel;
    } else {
        $useDefault = true;
    }
    if ($useDefault) {
        $attributeModel = Mage::getModel('googleshopping/attribute_default');
    }
    $attributeModel->setName($name);

    return $attributeModel;
}

@古斯：我看不出和这个有什么相似之处？？你说得对。我不记得了，我会删除它。我的错。
