Yii 对重载属性的间接修改
$winnerBid = Bids::model()->find($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'),
);
}
当我试图保存时:
$this->seller->current_item++;
$this->seller->wins++;
$this->seller->save();
我收到错误:
重载的间接修改property Bids::$seller 无效(/var/www/auction/www/protected/models/Bids.php:16)
Indirect modification of overloaded property Bids::$seller has no effect (/var/www/auction/www/protected/models/Bids.php:16)
但是在另一台服务器上一切正常吗?如何解决?或者覆盖 php 指令?有任何想法吗?TNX
推荐答案
这里的问题是 $seller
不是一个真正的"属性(Yii 通过使用魔法 __get
方法),因此实际上您正在尝试修改函数的返回值(无效).就好像你试图这样做:
The problem here is that $seller
is not a "real" property (Yii implements properties on its Models by using the magic __get
method), so in effect you are trying to modify the return value of a function (which has no effect). It is as if you tried to do:
function foo() {
return 42;
}
// INVALID CODE FOR ILLUSTRATION
(foo())++;
我不确定此行为在不同 PHP 版本上的状态,但您可以使用一个简单的解决方法:
I 'm not sure about the status of this behavior on different PHP versions, but there is an easy workaround you can use:
$seller = $this->seller;
$seller->current_item++;
$seller->wins++;
$seller->save();
