CakePHP: Using bindModel to trace backwards by 3 models? - mysql

Question

I have the following models:
-> = 1:many, <-> = many:many
User<->Product->MessageList<->Message
My goal with this query is to find all messages corresponding to the logged in . I also filter out messages that have been read (I find the messages ids in the prior find and store them in $messageIdsReadByPerson).
Here is my attempt:
// only grab messages belonging to this user
$this->Message->unbindModel(array('hasAndBelongsToMany'=>array('MessageListsMessage')));
$this->Message->bindModel( array(
'hasOne' => array(
'MessageListsMessage' => array(
'className' => 'MessageListsMessage',
'foreignKey' => false,
'type' => 'INNER',
'conditions' => array(
'MessageListsMessage.message_id = Message.id'
)
),
'MessageList' => array(
'className' => 'MessageList',
'foreignKey' => false,
'type' => 'INNER',
'conditions' => array(
'MessageList.id = MessageListsMessage.message_list_id'
)
),
'Product' => array(
'className' => 'Product',
'foreignKey' => false,
'type' => 'INNER',
'conditions' => array(
'Product.id = MessageList.product_id'
)
),
'ProductsUser' => array(
'className' => 'ProductsUser',
'foreignKey' => false,
'type' => 'INNER',
'conditions' => array(
'ProductsUser.product_id = Product.id'
)
),
'User' => array(
'className' => 'User',
'foreignKey' => false,
'conditions' => array(
'User.id = ProductsUser.user_id',
'User.id' => $this->Auth->user('id')
)
)
)
));
$messages = $this->Message->find('all', array(
'recursive' => -1
));
$this->set('messages', $messages);
But that only gives this query:
SELECT `Message`.`id`, `Message`.`text`, `Message`.`url` FROM `messages` AS `Message` WHERE 1 = 1
How can this be done properly using bindModel (or some easier method that I'm unaware of, although joins is apparently not the way to go).
EDIT:
this doesnt work either:
function index() {
// only grab messages belonging to this user
$messages = $this->Message->find('all', array(
'contain' => array(
'MessageList' => array(
'Product' => array(
'User.id = ' . $this->Auth->user('id')
)
)
)
));
$this->set('messages', $messages);
}

I think the same answer applies as I just gave here:
