class Academic_list extends CActiveRecord
{
public static function model($className=__CLASS__)
{
return parent::model($className);
}
public function relations()
{
return array(
'sorts'=>array(
self::BELONGS_TO, 'Academic_sort', 'sortid'
)
);
}
}
class Academic_sort extends CActiveRecord
{
public $subs = null;
public static function model($className=__CLASS__)
{
return parent::model($className);
}
public function relations()
{
return array(
'lists'=>array(
self::HAS_MANY, 'Academic_list', 'id'
)
);
}
}
$row = Academic_list::model()->with('sorts')->findByPk($id);
$row->sorts->name;
------解决方案--------------------
以上 Academic_list 表和 Academic_sort 表是一对多的关系.
希望对你有帮助.
祝你好运.
