Php Yii关系数据库不工作

我的UsersController上有这段代码

$userModel = Users::model()->with('userSubscriptionTypes')->find(array(
            'order'=>'userSubscriptionTypes.idUserSubscriptionType DESC',
            'limit'=>1,
            'condition'=>'t.paypal_profile_id=:paypal_profile_id', 
            'params'=>array(':paypal_profile_id'=>'I-S09AAFCLHH57')
        ));

这给了我一个错误：

CDbCommand failed to execute the SQL statement: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'userSubscriptionTypes.idUserSubscriptionType' in 'order clause'. The SQL statement executed was: SELECT `t`.`idUser` AS `t0_c0`, `t`.`username` AS `t0_c1`, `t`.`password` AS `t0_c2`, `t`.`email_address` AS `t0_c3`, `t`.`firstname` AS `t0_c4`, `t`.`lastname` AS `t0_c5`, `t`.`isAdmin` AS `t0_c6`, `t`.`paypal_profile_id` AS `t0_c7`, `t`.`date_created` AS `t0_c8` FROM `users` `t` WHERE (t.paypal_profile_id=:paypal_profile_id) ORDER BY userSubscriptionTypes.idUserSubscriptionType DESC LIMIT 1 

根据错误给出的SQL代码片段，带的

似乎不起作用

这是
Users.php
关系模型代码：

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(
            'trackedItems' => array(self::HAS_MANY, 'TrackedItems', 'idUser'),
            'userSubscriptionTypes' => array(self::HAS_MANY, 'UserSubscriptionType', 'idUser'),
        );
}

这个怎么了？还有想法

谢谢
 对于order子句，只需尝试使用
'order'=>'idUserSubscriptionType DESC'
。并确保在所选表中有列
idUserSubscriptionType
。实际上，我已经尝试了该列，但仍然存在该错误。您可以通过输出来检查查询吗？这是正在输出的查询：选择
t
idUser
作为
t0\uc0
，
t

其中（t.paypal\u profile\u id=：paypal\u profile\u id）ORDER BY userSubscriptionTypes.idUserSubscriptionType DESC LIMIT 1
idUserSubscriptionType
此列位于哪个表中？
