Magento。将数据保存在自定义表中

Question

我正在尝试在我的表中插入数据，但总是出现此错误

致命错误：调用未定义的方法 UltimoValue_Warranty_Model_Mysql4_Warranty_Collection::setData() /var/www/magento.dev/app/code/community/UltimoValue/Warranty/controllers/IndexController.php 第 17 行

这是IndexController中的保存代码

public function saveAction()
    {
        $warrantiesCollection = Mage::getModel('warranty/warranty')->getCollection();
        $post = $this->getRequest()->getPost();
        if(isset($post['order_number']) && isset($post['save'])) {
            try {
                $warrantiesCollection->setData('id', null);
                $warrantiesCollection->setData('first_name', $post['first_name']);
                $warrantiesCollection->setData('last_name', $post['last_name']);
                $warrantiesCollection->setData('order_number', $post['order_number']);
                $warrantiesCollection->setData('tablet_serial_number',                     $post['tablet_serial_number']);
                $warrantiesCollection->setData('date_purchased', $post['date_purchased']);
                $warrantiesCollection->save();
            } catch(Exception $e) {
                echo $e->getMessage(), "\n";
            }
            header("Location: " . $_SERVER['HTTP_ORIGIN'] . "/index.php/warranty/index/thankyou/");
            exit();
        }
    }

当我使用 getData - 一切都好...

我做错了什么？

Answer 1

改为

$warrantiesCollection = Mage::getModel('warranty/warranty')->getCollection();

我要写

$warrantiesCollection = Mage::getModel('warranty/warranty');

谢谢大家
