由于我的应用程序的构建方式,我需要为
beforeSaveAssociated
和 afterSaveAssociated
创建事件处理程序。为此,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,
),
));
}
尽管这对于模型类中定义的任何
beforeSaveAssociated
都适用,但每当我在行为中定义它时,它都不会被触发。如果我更新上面的 saveAssociated
来触发 Model.beforeSave
(内置事件),它确实有效,所以据我所知,这不是行为未正确附加的问题。
非常感谢任何帮助,
我认为这是因为BehaviorCollection只是监听这些事件(取自课堂):
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'
);
}
不是行为监听事件,而是集合并触发行为。如果不查的话,不能 100% 确定这一点,但我认为这就是它的工作原理。
你可以尝试做的是让需要接收这些事件的行为直接监听事件。
我认为这个问题是因为行为扩展了 ModelBehavior 并且这些类不知道您在 AppModel 中创建的新方法
