CakePHP saveAll（）不會刪除或更新連接表

我想要連接表自動更新/刪除。我在saveAll（）之前做了一個deleteAll（）作爲解決方法。CakePHP saveAll（）不會刪除或更新連接表

當我提交表單時，佈局和組件模型正確更新，但佈局組件模型（它是連接表）插入新數據（這是我想要的），但不刪除引用的數據。

佈局模型：

class Layout extends AppModel { 
    var $name = 'Layout'; 

    var $hasMany = array(
     'LayoutComponentOrder' => array(
      'className' => 'LayoutComponentOrder', 
      'foreignKey' => 'layout_id', 
      'dependent' => false, 
      'order' => 'LayoutComponentOrder.sort_id ASC', 
     ), 
     'ComponentVideo' => array(
      'className' => 'ComponentVideo', 
      'foreignKey' => 'layout_id', 
      'dependent' => false, 
     ), 
);}

組件模型：

class ComponentVideo extends AppModel { 
    var $name = 'ComponentVideo'; 
    //The Associations below have been created with all possible keys, those that are not needed can be removed 

    var $hasMany = array(
     'LayoutComponentOrder' => array(
      'className' => 'LayoutComponentOrder', 
      'foreignKey' => 'layout_component_id', 
      'dependent' => false, 
     ), 
    ); 

    var $belongsTo = array(
     'Layout' => array(
      'className' => 'Layout', 
      'foreignKey' => 'layout_id' 
     ), 
    ); 
};

佈局組件模型（合併表）：

class LayoutComponentOrder extends AppModel { 
    var $name = 'LayoutComponentOrder'; 
    var $uses = 'layout_component_orders'; 

    //The Associations below have been created with all possible keys, those that are not needed can be removed 

    var $belongsTo = array(
      'Layout' => array(
       'className' => 'Layout', 
       'foreignKey' => 'layout_id' 
      ), 
      'ComponentVideo' => array(
       'className' => 'ComponentVideo', 
       'foreignKey' => 'layout_component_id' 
      ) 
     ); 
}

佈局控制器：

// deleting the data manually 
$this->LayoutComponentOrder->deleteAll(array('LayoutComponentOrder.layout_id' => $layout_id)); 
// this one inserts into the tables including the join table   
$this->Layout->id = $layout_id; 
if ($this->Layout->saveAll($this->data)) { 
    $this->Session->setFlash(__('The layout has been saved', true)); 
}

如何自動刪除連接？這可能與CakePHP？
