使用 findAll 时 Yii AR join 不起作用

问题描述

我有两个表menus 和lang_menus.我的 Menus 模型如下:

I have two tables menus and lang_menus. My Menus model is as follows :

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);
    }

这会引发错误Unknown column 'menulanguages.languageId'.错误在 $menus = Menus::model()->with('menulanguages')->findAll($criteria); 行中.

This is throwing the error Unknown column 'menulanguages.languageId'.The error is in the line $menus = Menus::model()->with('menulanguages')->findAll($criteria);.

令人惊讶的是，我正确地获取了变量 $count 的值.

Surprisingly I am getting the value of the variable $count correctly.

在查看日志时，我可以看到为 findAll 查询运行的 SQL 查询是:

On looking at the log I can see that the SQL query that is running for the findAll query is :

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

这意味着连接尚未发生.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.

which means the join has not taken place. Whereas proper join query is running for the count value. Am I doing something wrong ?Please help.

推荐答案

只需使用 together() of CActiveRecord 或 together 属性:

Just use together() of CActiveRecord or 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;
