YII2中beforeSave和TimestampBehavior的使用,自动更新创建时间,更新时间

在开发过程中,经常会忘了给创建时间、更新时间等字段赋值,这里介绍两种自动更新时间的方法:

方法一:beforeSave

public function beforeSave($insert)
{
    if (parent::beforeSave($insert)) {
        if ($insert) {
            if ($this->hasAttribute('created_at')) {
                $this->created_at = time();
            }
        }
        if ($this->hasAttribute('updated_at')) {
            $this->updated_at = time();
        }
        return true;
    }
    return false;
}

方法二:TimestampBehavior

public function behaviors()
{
    return [
        [
            'class' => TimestampBehavior::className(),
            'attributes' => [
                ActiveRecord::EVENT_BEFORE_INSERT => ['created_at', 'updated_at'],
                ActiveRecord::EVENT_BEFORE_UPDATE => ['updated_at'],
            ],
            'value' => time(),
        ],
    ];
}
