请问一下我这样查询今天的数据，where 条件为什么报错呢？ [ 2.0 版本 ]

public static function isVoteCompany($type)
{
    $return = 0;
    $userInfo = UserService::getInstance()->getUser();
    if ($userInfo) {
        $row = (new Query())->from('service_vote')
            ->where([
                'user_id' => $userInfo['user_id'],
                'type' => $type，
                'to_days(add_time)' => 'to_days(now())',
            ])
            ->one();
        if ($row) {
            $return = 1;
        }
    }
    return $return;
}
