CakePHP 2.8 saveAll创建两条记录而不是一条

Question

我正在克隆一个带有相关数据的里程碑记录。我首先从源里程碑中找到数据，然后更改数组的内容并删除所有"id"字段。然后我尝试"saveAll"。所有相关数据都被正确创建，但"里程碑"表现在有2条新记录，而不是1条。第二条记录包含关联数据使用的ID，那么为什么第一条记录存在呢？

数据(简化)和调用：

$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);

在Model/Mestone.php中：

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' => ''
)
);

在Model/MilestoneAlert.php中：

public $belongsTo = array(
'Milestone' => array(
'className' => 'Milestone',
'foreignKey' => 'milestone_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);

在Model/MilestoneCondition.php中：

public $belongsTo = array(
'Milestone' => array(
'className' => 'Milestone',
'foreignKey' => 'milestone_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);

运行该方法后，在"milestone_conditions"中有两条记录，在"millestone_alerts"中有两家记录，并且在"里程碑"中有两家相同的记录。如何防止它创建两个"里程碑"记录？

Answer 1

尝试获取如下原始数据：

$test= $this->Milestone->findById('insert your id');
$this->Milestone->create(); // Create a new record
$this->Milestone->saveAll($test,array('deep' => true)); // And save it
