CakePHP find()及相关的模型和条件

我在我的游戏模型上调用find()以获得针对特定平台的该游戏的评论。问题是find()调用似乎没有关注我的条件数组。无论platform_id如何,该调用都会返回游戏的所有评论。

我有这些模型关联:

  • 用户有很多评论
  • 游戏有很多评论
  • 评论belongsTo Game
  • 评论belongsTo用户
  • 游戏HABTM平台

这是我创建的查找电话:

    $options = array(
        'group' => array(
            'Game.id'
        ),
        'joins' => array(
            array(
                'table' => 'reviews',
                'type' => 'LEFT',
                'conditions' => array(
                    'Game.id=reviews.game_id'
                )
            ),
            array(
                'table' => 'platforms',
                'type' => 'LEFT',
                'conditions' => array(
                    'reviews.platform_id=platforms.id'
                )
            ),
            array(
                'table' => 'users',
                'type' => 'LEFT',
                'conditions' => array(
                    'reviews.user_id=users.id'
                )
            )
        ),
        'fields' => array(
            'Game.id', 'Game.name',
            'platforms.id', 'platforms.name',
            'users.id', 'users.username'
        ),
        'conditions' => array(
            'AND' => array(
                'NOT' => array('reviews.review_text' => NULL),
                'platforms.id' => $pid,
            )
        ),
        'limit' => 5
    );

    $this->Game->find('all', $options);

以下是对platform_id = 2的find()调用的示例返回:

array(
(int) 0 => array(
    'Game' => array(
        'id' => '58',
        'name' => 'Bioshock 2'
    ),
    'platforms' => array(
        'id' => '2',
        'name' => 'PlayStation 3'
    ),
    'users' => array(
        'id' => '20',
        'username' => 'pspmaniac'
    ),
    'Review' => array(
        (int) 0 => array(
            'id' => '32',
            'review_text' => 'This is the PC review.',
            'score' => '4',
            'user_id' => '20',
            'game_id' => '58',
            'created' => '2013-04-30 19:59:40',
            'platform_id' => '10'
        ),
        (int) 1 => array(
            'id' => '33',
            'review_text' => 'This is the PS3 review.',
            'score' => '7',
            'user_id' => '20',
            'game_id' => '58',
            'created' => '2013-04-30 20:00:04',
            'platform_id' => '2'
        ),
        (int) 2 => array(
            'id' => '34',
            'review_text' => 'This is the XBOX 360 review.',
            'score' => '6',
            'user_id' => '20',
            'game_id' => '58',
            'created' => '2013-04-30 20:00:22',
            'platform_id' => '1'
        )
    )
)
);

在“评论”索引中,当它只返回platform_id = 2的评论时,它会返回游戏的三个评论(平台ID 10,2和1)。

这是我的reviews表:

CREATE TABLE reviews
(
   id mediumint unsigned not null auto_increment,
   review_text mediumint,
   score int not null,
   user_id mediumint unsigned not null,
   game_id mediumint unsigned not null,
   PRIMARY KEY (id),
   FOREIGN KEY (user_id) REFERENCES users (id),
   FOREIGN KEY (game_id) REFERENCES games (id)
);

因此,最后,返回数组唯一的错误是它不仅包含条件'platforms.id = 2'的评论,还包含所有平台ID的评论。

使用Dave的评论,我使用可包含的内容找到了我的问题的解决方案:

$this->loadModel('Review');
$this->Review->find('all', array( 'contain' => array('Platform'), 'conditions' => array( 'Review.platform_id' => 2 )
));
