Yii AR join 在使用 findAll 时不起作用

Question

我有两张桌子menus 和lang_menus。我的Menus 模型如下：

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(
                'menulanguages'=>array(self::HAS_MANY, 'MenuLangs', 'menuId'),
    );
}
...
public function getMenus(){
        $criteria = new CDbCriteria();
        $criteria->condition = "t.clientId = ".Yii::app()->user->clientId." AND menulanguages.languageId = ".Yii::app()->user->userlanguage;


        $count = Menus::model()->with('menulanguages')->count($criteria);

        $pages=new CPagination($count);
        //Results per page
        $pages->pageSize=10;
        $pages->applyLimit($criteria);

        $menus = Menus::model()->with('menulanguages')->findAll($criteria);
        return array('menus' => $menus, 'paging' => $pages);
    }

这是抛出错误Unknown column 'menulanguages.languageId'。 错误在$menus = Menus::model()->with('menulanguages')->findAll($criteria); 行中。

令人惊讶的是，我正确地获取了变量 $count 的值。

在查看日志时，我可以看到为 findAll 查询运行的 SQL 查询是：

SELECT `t`.`id` AS `t0_c0`, `t`.`clientId` AS `t0_c1`, `t`.`restaurantId` AS `t0_c2` FROM `posif_menus` `t` WHERE (t.clientId = 1 AND menulanguages.languageId = 2) LIMIT 10

这意味着连接没有发生。而正确的连接查询正在为计数值运行。难道我做错了什么 ？ 请帮忙。

Answer 1

只需使用together() of CActiveRecord 或together property of CDbCriteria：

$menus = Menus::model()->with('menulanguages')->together()->findAll($criteria);

或：

$criteria = new CDbCriteria();
$criteria->condition = "t.clientId = ".Yii::app()->user->clientId." AND menulanguages.languageId = ".Yii::app()->user->userlanguage;
$criteria->together=true;

Answer 2

试试这个..在 cdbcriteria 中应用连接表..

public function getMenus(){
        $criteria = new CDbCriteria();
        $criteria->condition = "t.clientId = ".Yii::app()->user->clientId." AND                                               menulanguages.languageId = ".Yii::app()->user->userlanguage;
        $criteria->with = array('menulanguages');

        $count = Menus::model()->count($criteria);

        $pages=new CPagination($count);
        //Results per page
        $pages->pageSize=10;
        $pages->applyLimit($criteria);

        $menus = Menus::model()->findAll($criteria);
        return array('menus' => $menus, 'paging' => $pages);
    }
