php – 简单的afterSave方法在Yii中不起作用

我想通过afterSave方法更新插入raw中的字段,因此我在Driver Model中开发了以下代码

protected function afterSave() {
        parent::afterSave();
        if ($this->isNewRecord) {
            $newid = self::newid($this->id);
            $this->updateByPk($this->id, new CDbCriteria(array('condition'=>'driverid = :driverid', 'params'=>array('driverid'=>  $newid))));
        }
}

以及在控制器中使用的方法：

public function actionCreate()
{
    $model=new Driver;

    // Uncomment the following line if AJAX validation is needed
    // $this->performAjaxValidation($model);

    if(isset($_POST['Driver']))
    {
        $model->attributes=$_POST['Driver'];
        if($model->save())
            $this->redirect(array('view','id'=>$model->id));
    }

    $this->render('create',array(
        'model'=>$model,
    ));
}

为什么保存后不起作用？

编辑：

    private static function CheckNumber($number) {
        $array = array(10);
        for ($i = 0; $i < 10; $i++)
            $array[$i] = 0;
        do {
            $array[$number % 10]++;
            $number /= 10;
        } while ((int) ($number / 10 ) != 0);
        $array[$number]++;

        for ($i = 0; $i < 10; $i++)
            if ($array[$i] > 1)
                return false;
        return true;
    }

public static function newid($id) {
    while (self::CheckNumber($id) == FALSE) {
        $id++;
    }
    return $id;
}

解决方法:

你的updateByPk搞砸了……

Check Documentation

因为它不清楚你想要做什么..所以我假设你想通过self :: newid($this-> id)的结果更新driver_id值;刚插入的行..

你应该做的是：

protected function afterSave() {
    parent::afterSave();
    if ($this->isNewRecord) {
        $newid = self::newid($this->id);
        $this->driverid = $new_id;
        $this->isNewRecord = false;
        $this->saveAttributes(array('driverid'));
    }
}

是的,你对afterSave的使用是正确的()

isNewRecord is true even after new record is created, but after first
time, it will be false always..
