CakePHP find() and related models and conditions - cakephp

Question

I am calling find() on my Game model in order to get the reviews of that game for a particular platform. The problem is that the find() call doesn't seem to be paying attention to my conditions array. The call returns all the reviews for a game regardless of the platform_id.
I have these model associations:
User hasMany Review
Game hasMany Review
Review belongsTo Game
Review belongsTo User
Game HABTM Platform
This is the find call that I created:
$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);
Here is a sample return for a find() call for platform_id=2:
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'
)
)
)
);
In the 'Review' index, it returns three reviews for the game (platform ids 10, 2, and 1) when it should only return the review with platform_id=2.
This is my reviews table:
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)
);
So, in the end, the only thing wrong with the returned array is that it contains reviews not only for the condition 'platforms.id=2' but for all platform ids.

Solution
Using Dave's comment, I came up with this solution to my problem using containable:
$this->loadModel('Review');
$this->Review->find('all', array( 'contain' => array('Platform'), 'conditions' => array( 'Review.platform_id' => 2 )
));
