关于数据类型（字段）表的高级关系

Question

这里是我的表，用户是经典的Auth表：

DataTypes

+----+--------------+
| id |    field     |
+----+--------------+
|  1 | address      |
|  2 | mobile_phone |
|  3 | city         |
+----+--------------+

UserData

+----+----------+--------------+---------+
| id |  value   | data_type_id | user_id |
+----+----------+--------------+---------+
|  1 | Milan    |            3 |       1 |
|  2 | 99123233 |            2 |       1 |
+----+----------+--------------+---------+

我当前的疯狂模特：

class User extends Authenticatable {
    public function field($field){
        $field=DataType::where('field',$field)->first();
        return $this->hasMany('App\UserData')->where('datatype_id',(isset($field->id) ? $field->id : 0));
    }    
}

当然，当我必须找到值时，它可以很好地工作：

auth()->user()->field('mobile_phone')->get();

但是如何设置或更新新手机？

Answer 1

auth()->user()->field('mobile_phone')->save([
      'field' => 'value'
])
