由于我的应用程序是如何构建的,我需要为beforeSaveAssociated
和afterSaveAssociated
创建事件处理程序。为了实现这一点,我更新了AppModel.php以包含以下相关代码:
public function saveAssociated(array $data = null, array $options = array()) {
$this->after_save_options = NULL;
$event = new CakeEvent('Model.beforeSaveAssociated', $this, array(&$data, &$options));
$this->after_save_options = NULL;
$this->getEventManager()->dispatch($event);
if (parent::saveAssociated($data, $options)) {
if (is_array($this->after_save_options)) {
$curData = $this->data;
$this->data = $this->_tempData;
$event = new CakeEvent('Model.afterSaveAssociated', $this, $this->after_save_options);
$this->after_save_options = NULL;
$this->getEventManager()->dispatch($event);
$this->data = $curData;
}
if ($this->_tempData) {
$this->_tempData = FALSE;
}
return TRUE;
}
return FALSE;
}
public function implementedEvents() {
return array_merge(parent::implementedEvents(), array(
'Model.beforeSaveAssociated' => array(
'callable' => 'beforeSaveAssociated',
'passParams' => TRUE,
),
'Model.afterSaveAssociated' => array(
'callable' => 'afterSaveAssociated',
'passParams' => TRUE,
),
));
}
虽然这适用于模型类中定义的任何beforeSaveAssociated
,但每当我在行为中定义它时,它都不会被触发。如果我更新saveAssociated
以触发Model.beforeSave
(内置事件),它确实有效,所以据我所知,这不是一个没有正确附加行为的问题。
非常感谢任何帮助,

我认为这是因为BehaviorCollection只是在监听这些事件(取自该类):
public function implementedEvents() {
return array(
'Model.beforeFind' => 'trigger',
'Model.afterFind' => 'trigger',
'Model.beforeValidate' => 'trigger',
'Model.afterValidate' => 'trigger',
'Model.beforeSave' => 'trigger',
'Model.afterSave' => 'trigger',
'Model.beforeDelete' => 'trigger',
'Model.afterDelete' => 'trigger'
);
}
不是行为会监听事件,而是集合并在行为上触发它们。不是100%肯定没有查找,但我认为这是如何工作。
您可以尝试做的是使需要直接接收这些事件的行为来监听事件。

我认为这个问题是因为行为扩展了ModelBehavior而这些类不知道您在AppModel中创建的新方法
