Laravel中传递了参数1

Question

我在Laravel中的代码中有错误。

它显示了这一点

传递给Order \\ Order :: __ construct（）的参数1必须是System \\ RewardPoint的实例，未提供任何实例，在C：\\ xampp \\ htdocs \\ stardibs-version2 \\ stardibs-v2 \\ vendor \\ laravel \\ framework \\ src \\ Illuminate中调用\\ Database \\ Eloquent \\ Model.php在第647行并已定义

order.php

use BaseModel, DB; 
use Eloquent, User\User, Auth, Cart, Order\Order; 
use System\RewardPoint as RewardPoint; 

class Order extends BaseModel {

    public function __construct(RewardPoint $rewardPoint)
    {
        $this->rewardPoint = $rewardPoint;

    }
}

有什么解决方案？

创建Order类的objecct时，需要将对象RewardPoint传递给其构造函数：

$rewardPoint = new RewardPoint(/** whatever arguments are needed **/);
$order = new Order($rewardPoint);
