【问题描述】：
所以我试图“喜欢”一个状态，当我这样做时，我得到这个错误作为回报
ErrorException in User.php line 107:
Argument 1 passed to SCM\User::hasLikedStatus() must be an instance of Status, instance of SCM\Status given, called in C:\xampp\htdocs\app\Http\Controllers\StatusController.php on line 66 and defined
当我删除“使用状态；”从我的 User.php 中，该功能起作用，并使用类似的 ID 更新了我的数据库。这可能是因为我链接了我的状态的公共功能，如“SCM\Status”吗？
