v4.0.51 mongo模型onAfterWrite回调数据没有id值

示例代码:

class MongoUser extends Model {
    public static function onAfterWrite($user)
    {
        $task = $user->toArray();
        trace($task, 'debug');
    }
}

$data = ['name':'Ben','age':20];
MongoUser::create($data);

发现onAfterWrite($user) 返回的$user 没有主键信息, 取不到$user['id']值

问题出现在 src/Model.php 403-408行

// 写入自增键值
            $key = $db->getAutoInc();
            $val = $db->getLastInsID();
            if ($key && $val) {
                $this->setData($key, $val);
            }

其中 $key = $db->getAutoInc(); $key是空字符串, 本来想自己修复一下改为如下:

// 写入自增键值
            $key = $db->getAutoInc();
            if(empty($key) && $db instanceof db\Mongo){
                $key = $db->getPk();
            }
            $val = $db->getLastInsID();
            if ($key && $val) {
                $this->setData($key, $val);
            }

这样$key='_id'会写入_id的值, 但是在onAfterWrite($user)中取值$user['id']还是无法取到,只要$user['_id']有值

Start in src/Model.php around lines 403-408 and trace the Mongo write path through getAutoInc(), getLastInsID(), getPk(), and onAfterWrite(). Reproduce the MongoUser::create example and inspect the callback payload; done means the written primary-key data is consistently available in the callback according to the model's expected key representation.
