Yii:如何计算模型中的记录？

Question

我有以下代码从模型中获取数据.

$notifyModel = Notification::model()->findByAttributes(array(
                  'user_id'=> Yii::app()->user->uid
               ));

现在我想计算提取的行数.无论是$notifyModel->count()工作还是工作count($notifyModel).这很简单,但谷歌搜索没有帮助.

Answer 1

$notifyModels = Notification::model()->findAllByAttributes(array(
            'user_id'=> Yii::app()->user->uid
        ));

$count = count($notifyModels);

要么

$count = Notification::model()->countByAttributes(array(
            'user_id'=> Yii::app()->user->uid
        ));

Answer 2

count()的正确用法:

    $userid =  Yii::app()->user->uid;
    $count = Notification::model()->count( 'user_id=:userid', array(':userid' => $userid));
