Php 每次获取Yii2的现有验证程序时出错

以下是我从数据库验证活动id的代码 但每次我得到错误的天气记录是在分贝或不是

[campaign_id', 'exist', 'targetClass' => '\common\models\Campaign', 'filter' => ['campaign_id' => Campaign::className()], 'message' => 'There is no record with this id.' ]]

我找到了解决方案，只是移除了这个过滤器，它开始工作了

['campaign_id', 'exist',
            'targetClass' => '\common\models\Campaign',
            'message' => 'There is no user with this email address.'
        ]

此id在db中是唯一的
