我收到一个对laravel的http调用，我想获取传入的数据并将其插入表的一列中。这是我的密码： $data = Input::all(); 这是我的数据来自http $user = User::find($data['user_id']); 这是从mysql数据库的user表中查找用户。

+----+------------+-------------------------+------------+-----------+------------------------------------------------------------------+-------+---------------------+---------------------+----------+----------+------------+-------------+------------------+--------------------------------------------------------------+-------------+-----------------------+------------------+--------------+
| id | account_id | email  | first_name | last_name | token | fb_id | created_at | updated_at | location | fb_token | deleted_at | access_code | is_account_admin | password | username    | deleted_with_location | is_video_enabled | device_token |
+----+------------+-------------------------+------------+-----------+------------------------------------------------------------------+-------+---------------------+---------------------+----------+----------+------------+-------------+------------------+--------------------------------------------------------------+-------------+-----------------------+------------------+--------------+

所以我想插入 $data['deviceToken'] 进入 deviceToken 此表的列。
如何在我的laravel控制器上执行此操作？
谢谢！
