CakePHP saveAll（）不会删除或更新连接表

我想要连接表自动更新/删除。我在saveAll（）之前做了一个deleteAll（）作为解决方法。CakePHP saveAll（）不会删除或更新连接表

当我提交表单时，布局和组件模型正确更新，但布局组件模型（它是连接表）插入新数据（这是我想要的），但不删除引用的数据。

布局模型：

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, 
     ), 
);}

组件模型：

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' 
     ), 
    ); 
};

布局组件模型（合并表）：

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' 
      ) 
     ); 
}

布局控制器：

// 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)); 
}

如何自动删除连接？这可能与CakePHP？
