我正在使用Laravel 5并且有多个模型(患者,治疗师)从用户模型扩展.

我在DB中有一些虚拟数据(很少有治疗师,很少有患者).

当我想通过id检索治疗师时,我尝试通过Therapist :: find($id)这样做,但得到一个例外：

'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.如何在从User扩展的对象上使用:: find函数以获取每个模型的属性？

编辑

Ajax调用

/getTherapist

routes.php文件：

Route::get('/getTherapist', 'HomeController@getTherapist');

HomeController.php：

public function getTherapist()
{
    $user = Therapist::find(13);
    return $user->toArray();
}

完全例外：

最佳答案 你在Therapist Models中定义了__construct()方法,不是吗？

我猜你错过了$attributes param：

public function __construct($attributes = array())
{
    parent::__construct($attributes);
    //do your construction stuff
}
