Models : Listings and Auctions
关系: Auctions BELONGS_TO Listings
Listings PK : id
Auctions FK : Listings_id

问题: 如果（保存期间连接缓慢/丢失）列表 PK 和 Auction ，我如何在我的 VIEW 中获取两个表的所有属性（对象） FK不一样。

模型（拍卖）

public function relations()
{

    // NOTE: you may need to adjust the relation name and the related
    // class name for the relations automatically generated below.
    return array(
        'listings' => array(self::BELONGS_TO, 'Listings', 'listing_id'),
    );

}

控制器

$randomListing= new RandomListingGenerator();
$randomListing=$randomListing->actionGenerate();
$profile=new Profile;
            $this->render('index', array(
                'data' => $randomListing,   
            ));

随机列表生成器

class RandomListingGenerator{
    public function actionGenerate(){
$criteria = new CDbCriteria();
        $criteria->select = '*, RAND() as rand';
        $criteria->order = 'rand';
        $criteria->limit = 1;
        $criteria->together = true;
        $criteria->with=array(
                'listings'=>array('select'=>'id'),
        );

        return $randomListing = Auctions::model()->find($criteria);
 }

}

看法

echo $data->listings->rooms; 
//other attributes ....

我收到了这个错误
