Cakephp通过查找选项连接表不工作

我正在尝试将用户表连接到我当前的hasMany Through表，该表具有兴趣和用户模型id。

下面是带有选项的查找查询:

$params = array(
                    'fields' => array('*', 'COUNT(DISTINCT(InterestsUser.interest_id)) as interest_count'),
                    'limit' => 15,
                    'recursive' => -1,
                    'offset' => $offset,
                    'conditions' => array('InterestsUser.interest_id' => $conditions),
                    'group' => array('InterestsUser.user_id'),
                    'order' => array('interest_count DESC', 'InterestsUser.user_id ASC', 'InterestsUser.interest_id ASC'),
                        'joins' => array(
                            array('table' => 'users',
                                'alias' => 'User',
                                'type' => 'LEFT',
                                'conditions' => array(
                                    'User.id' => 'InterestsUser.user_id',
                                )
                            )
                        )
                    );
            $results = $this->InterestsUser->find('all', $params);

返回InterestsUser表，但不返回Users表的任何值。它只返回字段名。

怎么了?

更新:好的，上面是生成下面的SQL，我从蛋糕的数据源SQL日志:

SELECT *, COUNT(DISTINCT(InterestsUser.interest_id)) as interest_count 
FROM `interests_users` AS `InterestsUser` 
LEFT JOIN users AS `User` ON (`User`.`id` = 'InterestsUser.user_id')  
WHERE `InterestsUser`.`interest_id` IN (3, 2, 1)  
GROUP BY `InterestsUser`.`user_id`  
ORDER BY `interest_count` DESC, `InterestsUser`.`user_id` ASC, `InterestsUser`.`interest_id` ASC  
LIMIT 15

为什么用户表值返回NULL只对所有字段?

更新:

好吧，我在下面试过了，但这工作得很好…我错过了什么?

SELECT * , COUNT( DISTINCT (
interests_users.interest_id
) ) AS interest_count
FROM interests_users
LEFT JOIN users ON ( users.id = interests_users.user_id ) 
WHERE interests_users.interest_id
IN ( 1, 2, 3 ) 
GROUP BY interests_users.user_id
ORDER BY interest_count DESC 
LIMIT 15
