Object 无法加载（或找到）对象的预设置

目前，我正在为我的客户开发定制忠诚度计划。 我将在单独的选项卡中显示这些点，如下所示。 忠诚度计划>客户列表>查看他们的积分>编辑积分

当我单击一个客户时，它将呈现客户点列表，但呈现没有问题，但它显示以下错误

无法加载或找到该对象

请帮我克服这个错误

LoyaltyClass.php

renderView不需要以下代码

$this->table='loyaltyprogram'； $this->className='LoyaltyClass'； $this->module='loyaltyprogram'

您需要包括类文件，如：

需要_oncedirnameFILE'/../../classes/LoyaltyClass.php'

您需要调用loadObject方法，而不是创建一个新的LoyaltyClas实例，因为它将$this->object设置为：

如果$obj=$this->loadObjecttrue 返回

如果在renderList中不使用$obj，则不必加载它

---

类文件的名称和位置如何？类文件名为loyaltyclass.php，其位于我的模块类folderHi中，正如您所说，我将我的类包括在我的忠诚度控制器中，但我仍然面临错误。请检查上面修改的代码和类。

class LoyaltyClass extends ObjectModel
{

/** @var string Name */
public $id_loyaltyprogram;

/** @var integer */
public $id_order;

/** @var integer */
public $point;
public $date;

/**
 * @see ObjectModel::$definition
 */
public static $definition = array(
    'table' => 'loyaltyprogram',
    'primary' => 'id_loyaltyprogram',
    'multilang' => false,
    'fields' => array(
        'id_loyaltyprogram' => array('type' => self::TYPE_INT, 'validate' => 'isInt'),
        'id_order' => array('type' => self::TYPE_INT, 'validate' => 'isInt', 'required' => true),
        'id_customer' => array('type' => self::TYPE_INT, 'validate' => 'isInt', 'required' => true),
        'point' => array('type' => self::TYPE_FLOAT, 'validate' => 'isUnsignedFloat', 'required' => true),
        'date' => array('type' => self::TYPE_STRING, 'validate' => 'isCleanHtml', 'required' => true),
    ),
);

public static function loadLoyaltyProgram()
{
    $result = Db::getInstance()->getRow('
        SELECT *
        FROM `' . _DB_PREFIX_ . 'loyaltyprogram` order_qty
        '
    );
    return new LoyaltyClass($result['id_loyaltyprogram']);
}
