CakePHP 2.8 saveAll Creates Two Records Instead of One - cakephp-2.0

Question

I'm cloning a milestone record with associated data. I first find the data from the source milestone, then change the contents of the array and remove all 'id' fields. Then I attempt a 'saveAll'. All the associated data is being created properly but the 'milestones' table now has 2 new records instead of 1. The second record contains the ID used by the associated data, so why does the first record even exist?
The Data (simplified) and Call:
$test = array(
'Milestone' => array(
'name' => 'Clone Test',
'customer_status' => '',
'time_to_complete' => '1',
'is_active' => true,
),
'MilestoneAlert' => array(
(int) 0 => array(
'name' => 'Clone Test',
'type' => 'customer',
'milestone_alert_type_id' => '0',
'email' => null,
'subject' => 'First alert!',
'message' => 'Add a message',
'recipient_name' => '',
'is_active' => true,
),
(int) 1 => array(
'name' => 'Clone Test 1',
'type' => 'customer',
'milestone_alert_type_id' => '0',
'email' => null,
'subject' => 'Second alert!',
'message' => 'Add a message',
'recipient_name' => '',
'is_active' => true,
)
),
'MilestoneCondition' => array(
(int) 0 => array(
'name' => 'Clone Test',
'condition' => 'First condition.',
'is_active' => true,
),
(int) 1 => array(
'name' => 'Clone Test 1',
'condition' => 'Second condition.',
'is_active' => true,
)
)
);
$this->loadModel('Milestone');
$this->Milestone->create();
$this->Milestone->saveAll($test);
In Model/Milestone.php:
public $hasMany = array(
'MilestoneAlert' => array(
'className' => 'MilestoneAlert',
'foreignKey' => 'milestone_id',
'dependent' => false,
'conditions' => '',
'fields' => '',
'order' => '',
'limit' => '',
'offset' => '',
'exclusive' => '',
'finderQuery' => '',
'counterQuery' => ''
),
'MilestoneCondition' => array(
'className' => 'MilestoneCondition',
'foreignKey' => 'milestone_id',
'dependent' => false,
'conditions' => '',
'fields' => '',
'order' => 'MilestoneCondition.order',
'limit' => '',
'offset' => '',
'exclusive' => '',
'finderQuery' => '',
'counterQuery' => ''
)
);
In Model/MilestoneAlert.php:
public $belongsTo = array(
'Milestone' => array(
'className' => 'Milestone',
'foreignKey' => 'milestone_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);
In Model/MilestoneCondition.php:
public $belongsTo = array(
'Milestone' => array(
'className' => 'Milestone',
'foreignKey' => 'milestone_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);
After running the method, there are two records in 'milestone_conditions', two records in 'milestone_alerts', and two identical records in 'milestones'. How do I keep it from creating two 'milestone' records?

Answer 1

Try to get the original data like this:
$test= $this->Milestone->findById('insert your id');
$this->Milestone->create(); // Create a new record
$this->Milestone->saveAll($test,array('deep' => true)); // And save it
