$winnerBid = Bids::model()->find($criteria);

模型有下一个关系:

public function relations() {
        return array(
            'item' => array(self::BELONGS_TO, 'Goods', 'item_id'),
            'room' => array(self::BELONGS_TO, 'Rooms', 'room_id'),
            'seller' => array(self::BELONGS_TO, 'RoomPlayers', 'seller_id'),
            'buyer' => array(self::BELONGS_TO, 'RoomPlayers', 'buyer_id'),
        );
    }

当我想保存时:

 $this->seller->current_item++;
    $this->seller->wins++;
    $this->seller->save();

我收到错误:

间接修改超载属性投标:: $卖方无效(/var/www/auction/www/protected/models/Bids.php:16)

但是在另一台服务器上一切都很好吗？怎么解决？或者覆盖php指令？有任何想法吗？TNX
