Yii条件关系问题

我遇到了Yii条件的问题。

我的代码：

$criteria=new CDbCriteria;
//$criteria->together = true;
$criteria->group='t.id';
$criteria->with = array('farmer_goods','goods_catalog');
//$criteria->compare('farmer_goods.price', '<>0');
$criteria->compare('goods_catalog.name', $this->_params['category']);

在这种情况下，它按照我想要的方式工作（我得到了物品清单，每个物品都有一个有农民的清单，这个物品的1个类别是相对的。

但问题是我需要按照农民表中存储的项目的价格对列表进行排序。

所以，如果我取消注释这一行：

//$criteria->compare('farmer_goods.price', '<>0');

我明白了：

SELECT `t`.`id` AS `t0_c0`, `t`.`catalog_id` AS `t0_c1`, `t`.`articul` AS `t0_c2`, `t`.`###name` AS `t0_c3`, `t`.`name_rus` AS `t0_c4`, `t`.`ed_izm` AS `t0_c5`, `t`.`srok_godnosti` AS `t0_c6`, `t`.`temp_hraneniya` AS `t0_c7`, `t`.`belki` AS `t0_c8`, `t`.`jiri` AS `t0_c9`, `t`.`uglevodi` AS `t0_c10`, `t`.`kalorii` AS `t0_c11`, `t`.`gost` AS `t0_c12`, `t`.`photo` AS `t0_c13`, `t`.`opisanie` AS `t0_c14`, `goods_catalog`.`id` AS `t2_c0`, `goods_catalog`.`parent_id` AS `t2_c1`, `goods_catalog`.`unique_name` AS `t2_c2`, `goods_catalog`.`name` AS `t2_c3`, `goods_catalog`.`name_rus` AS `t2_c4`, `goods_catalog`.`rout_url` AS `t2_c5`, `goods_catalog`.`launch_model` AS `t2_c6`, `goods_catalog`.`photo` AS `t2_c7` FROM `goods_details` `t` LEFT OUTER JOIN `goods_catalog` `goods_catalog` ON (`t`.`catalog_id`=`goods_catalog`.`id`) WHERE (((farmer_goods.price LIKE :ycp0) AND (farmer_goods.price<>:ycp1)) AND (goods_catalog.name=:ycp2)) GROUP BY t.id LIMIT 50

你可以看到没有与农民的联系：

FROM `goods_details` `t` LEFT OUTER JOIN `goods_catalog` `goods_catalog` ON (`t`.`catalog_id`=`goods_catalog`.`id`)

如果我取消注释：

//$criteria->together = true;

它解决了这个问题，但作为回应我得到了1名农民的名单（这不是我想要的）

我想我必须在标准中做一些标准，但是如何？

我的关系 TradeGoods 

            'farmer_goods'=>array(self::HAS_MANY, 'FarmersGoods', array('articul'=>'articul')),
            'goods_catalog'=>array(self::BELONGS_TO, 'GoodsCatalog', array('catalog_id'=>'id')),

修改

通过phpmyadmin手动发布SQL查询可以得到很好的结果

SELECT 
`t`.`id` AS `t0_c0`, 
`t`.`catalog_id` AS `t0_c1`, 
`t`.`articul` AS `t0_c2`, 
`t`.`###name` AS `t0_c3`, 
`t`.`name_rus` AS `t0_c4`, 
`t`.`ed_izm` AS `t0_c5`, 
`t`.`srok_godnosti` AS `t0_c6`, 
`t`.`temp_hraneniya` AS `t0_c7`, 
`t`.`belki` AS `t0_c8`, 
`t`.`jiri` AS `t0_c9`, 
`t`.`uglevodi` AS `t0_c10`, 
`t`.`kalorii` AS `t0_c11`, 
`t`.`gost` AS `t0_c12`, 
`t`.`photo` AS `t0_c13`, 
`t`.`opisanie` AS `t0_c14`, 
`farmer_goods`.`id` AS `t1_c0`, 
`farmer_goods`.`farmer_id` AS `t1_c1`, 
`farmer_goods`.`articul` AS `t1_c2`, 
`farmer_goods`.`price` AS `t1_c3`, 
`farmer_goods`.`fasovka` AS `t1_c4`, 
`farmer_goods`.`fasovka_options` AS `t1_c5`, 
`farmer_goods`.`count_left` AS `t1_c6`, 
`goods_catalog`.`id` AS `t2_c0`, 
`goods_catalog`.`parent_id` AS `t2_c1`, 
`goods_catalog`.`unique_name` AS `t2_c2`, 
`goods_catalog`.`name` AS `t2_c3`, 
`goods_catalog`.`name_rus` AS `t2_c4`, 
`goods_catalog`.`rout_url` AS `t2_c5`, 
`goods_catalog`.`launch_model` AS `t2_c6`, 
`goods_catalog`.`photo` AS `t2_c7` 
FROM 
`goods_details` `t` 
LEFT OUTER JOIN 
`farmers_goods` `farmer_goods` 
ON 
(`farmer_goods`.`articul`=`t`.`articul`) 
LEFT OUTER JOIN 
`goods_catalog` `goods_catalog` 
ON 
(`t`.`catalog_id`=`goods_catalog`.`id`) 
WHERE 
(`goods_catalog`.`name`='meet')

GROUP BY `t`.`id`
ORDER BY `farmer_goods`.`price`

但是当像这样推出Yii排序时

$sort = new CSort('FarmersGoods');
$sort->attributes = array(
    'price'=>array(
        'asc'=>'farmer_goods.price ASC',
        'desc'=>'farmer_goods.price DESC',
    ),
    '*',
);

它“失败”：

LEFT OUTER JOIN 
    `farmers_goods` `farmer_goods` 
    ON 
    (`farmer_goods`.`articul`=`t`.`articul`)

我发现了一个问题 我真的希望帮助像我这样的人，节省时间 所以重点在于，当您对BELONGS_TO或HAS_ONE进行排序时，没有问题可以使用

$criteria=new CDbCriteria;
$criteria->group='t.id';
$criteria->with = array('farmer_goods');

并按

排序 
    $sort = new CSort('FarmersGoods');
    $sort->attributes = array(
        'price'=>array(
            'asc'=>'farmer_goods.price ASC',
            'desc'=>'farmer_goods.price DESC',
        ),
    );

但是当你需要对HAS_MANY进行排序（可能还有MANY_MANY，未经过测试）时，你需要编写这样的标准

$criteria=new CDbCriteria;
$criteria->group='t.id';
$criteria->with = array('farmer_goods'=>array('together'=>true),'goods_catalog');

这不是很明显，但是一个不同的重要事项，可以让您按相关的HAS_MANY表属性进行排序

顺便说一句 - 抱歉我的英文不好
