我在創(chuàng)建模型時(shí)遇到異常。這是該異常：

1 exception(s):
Exception #0 (InvalidArgumentException): Training4VendorModelTraining4_Vendor2Product does not extend MagentoFrameworkDataObject

Exception #0 (InvalidArgumentException): Training4VendorModelTraining4_Vendor2Product does not extend MagentoFrameworkDataObject

Magento 版本是 2.4.4 Training4VendorModelTraining4_Vendor2Product

<?php


namespace Training4VendorModel;


use MagentoFrameworkModelAbstractModel;

class Training4_Vendor2Product extends AbstractModel
{
    const vendor_id='id';

    protected $_idFieldName  = self::vendor_id;

    protected function _construct()
    {
        $this->_init(Training4VendorModelResourceModelTraining4_Vendor2Product::class);
    }
}

Training4VendorModelResourceModelTraining4_Vendor2Product

<?php


namespace Training4VendorModelResourceModel;


use MagentoFrameworkModelResourceModelDbAbstractDb;

class Training4_Vendor2Product extends AbstractDb
{

    protected function _construct()
    {
        $this->_init('training4_vendor2product','id');
    }
}

Training4VendorModelResourceModelTraining4_Vendor2ProductCollection

<?php


namespace Training4VendorModelResourceModelTraining4_Vendor2Product;


use MagentoFrameworkModelResourceModelDbCollectionAbstractCollection;

class Collection extends AbstractCollection
{
    protected $_idFieldName = 'id';

    protected function _construct()
    {
        $this->_init(Training4VendorModelTraining4_Vendor2Product::class,
            Training4VendorModelResourceModelTraining4_Vendor2Product::class);
    }
}

在 Training4VendorModelTraining4_Vendor2Product 中，我已經(jīng)擴(kuò)展了 MagentoFrameworkModelAbstractModel，我不知道為什么會(huì)發(fā)生該異常
