CakePHP saveAll not saving key of 2nd level dependent - cakephp

Question

I am using cake PHP 2.x. My Database is set up like this.
Rating Has One Review
Review Has Many Photo
data => array(
'Rating' => array(
'rating' => '1',
'user_id' => '1',
'listing_id' => '55'
),
'Review' => array(
'title' => 'Good Service',
'date_visited' => array(
'month' => '05',
'day' => '28',
'year' => '2013',
),
'service_used' => 'Easy Checkout',
'description' => 'After a fairly quick check-in, the check out service was also breeze ',
'Photo' => array(
(int) 1 => array(
'title' => 'Test',
'photo' => array(
'name' => '2.JPG',
),
'listing_id' => '55',
'user_id' => '1'
)
)
)
)
Review.php
public $hasMany = array(
'Photo' => array(
'className' => 'Photo',
'conditions' =>'',
'order' => ''
)
);
Photo.php
public $belongsTo = array(
'User' => array(
'className' => 'User',
'foreignKey' => 'user_id',
'conditions' => '',
'fields' => '',
'order' => ''
),
'Review' => array(
'className' => 'Review',
'foreignKey' => 'review_uuid',
'conditions' => '',
'fields' => '',
'order' => ''
),
'Listing' => array(
'className' => 'Listing',
'foreignKey' => 'listing_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);
And Finally RatingsController.php
$this->Rating->create();
if ($this->Rating->saveAll($this->request->data, array('deep' => true))) {
$this->Session->setFlash(__('The rating has been saved'));
$this->redirect(array('action' => 'index'));
}
The issue is all the data is getting saved, except review_uuid (which is also being created simultaneously) )in Photos model.
mysql> select id,user_id,listing_id,review_uuid,title,photo,photo_dir from photos where ID=26;
+----+---------+------------+-------------+-------+--------------------------------------+----------- +
| id | user_id | listing_id | review_uuid | title | photo | photo_dir |
+----+---------+------------+-------------+-------+--------------------------------------+----------- +
| 26 | 1 | 55 | NULL | Test | 1a107372ef53ba26d7748a50c25e6b27.jpg | 01/77/74 |
+----+---------+------------+-------------+-------+--------------------------------------+-----------+

Answer 1

It doesn't look like your defining the foreign key in the hasMany relationship in Review found in Photo, your not completing the relation.
Your hasMany array in Review.php should look like:
public $hasMany = array(
'Photo' => array(
'className' => 'Photo',
'foreignKey' => 'review_uuid',
'conditions' =>'',
'order' => ''
)
);
Note the foreignKey parameter. You are telling Cake that Review has many photos and each photo record has a foreign key named review_uuid used to identify it's relationship to a review. You were defining the foreign key in your belongsTo array in the Photo model but not in your hasMany array in the Review model, so the relation was never completed.
You should also define a belongsTo relation between Review and Rating
In Review.php:
public $hasMany = array(
'Photo' => array(
'className' => 'Photo',
'foreignKey' => 'review_uuid',
'conditions' =>'',
'order' => ''
)
);
public $belongsTo = array(
'Rating' => array(
'className' => 'Rating',
'foreignKey' => 'rating_id',
'conditions' => '',
'order' => ''
)
);
