我正在使用 Laravel 5 并且有多个模型(Patient、Therapist)从 User 模型扩展而来。
我在数据库中有一些虚拟数据(很少有治疗师，很少有病人)。
当我想通过 id 检索治疗师时，我尝试通过 Therapist::find($id) 这样做，但出现异常:
'Illuminate\Database\QueryException' with message 'SQLSTATE[23000]:
Integrity constraint violation: 1062 Duplicate entry '' for key
'users_email_unique' (SQL: insert into users`
几个问题:
1. 为什么当我使用::find 函数时，它会尝试插入一个新用户？
2. 如何对从 User 扩展的对象使用 ::find 函数以获得每个模型具有的属性？
Ajax 调用
/getTherapist
路由.php:
Route::get('/getTherapist', 'HomeController@getTherapist');
HomeController.php:
public function getTherapist()
{
$user = Therapist::find(13);
return $user->toArray();
}
完全异常:

您在 Therapist Models 中定义了 __construct() 方法，不是吗？ 我猜你错过了 $attributes 参数:
public function __construct($attributes = array())
{
parent::__construct($attributes);
//do your construction stuff
}
