php - 我怎样才能在 laravel 上只获得第一个标签关系？

Question

我有SaleInvoice模型，销售发票属于User模型，User模型属于另一个名为Client. 在User模型上，我使用急切加载来加载Client

class User extends Authenticatable
{

    /**
     * The relations to eager load on every query.
     *
     * @var array
     */
    protected $with = ['client'];
}

问题是，当我渴望加载User模型SaleInvoice时，它也会加载Client

class SaleInvoice extends Model
{

    /**
     * The relations to eager load on every query.
     *
     * @var array
     */
    protected $with = ['user'];
}

** 有没有办法只加载Userwith SaleInvoice？Client注意：加载也很重要User
