Cakephp 删除HABTM关系的联接表中的记录

关系如下所示：

Podcasts <-HABTM-> Users

UserController.php

public function removePodcast($podcastId, $userId){
    if(empty($podcastId) || empty($userId)) return false;

    $this->User->PodcastsUser->deleteAll(array(
        'PodcastsUser.podcast_id' => $this->data['Podcast'][$podcastId], 
        'PodcastsUser.user_id' => $this->data['Podcast'][$userId]
    ));
}

public function removepodcast($podcastId, $userId){
    //$this->loadModel('PodcastsUser');
    $this->User = ClassRegistry::init('PodcastsUser');

    if ($this->User->removePodcast($podcastId, $userId)){
        $this->Session->setFlash(__('The podcast has been removed'));
        $this->redirect(array('controller' => 'users', 'action' => 'index'));
    }else {
            $this->Session->setFlash(__('The podcast could not be removed. Please, try again.'));
        }
}

查看/用户/

echo $this->Html->link(__('Remove'), array('controller' => 'users', 'action' => 'removepodcast', $mypodcast['Podcast']['id'], $this->Session->read('Auth.User.id')));

我看了这个，但我不清楚。

请帮我举个例子或改正，我将不胜感激

您只需要在UserController上调用此函数$此->用户->删除播客（）；我现在添加了更多代码谢谢，现在有什么问题？任何错误？是：

未定义索引：Podcast[APP/Model/PodcastsUser.php

和

该Podcast已作为flash消息删除。感谢您的帮助在模型函数中将$this->data['Podcast'][$podcastId]替换为podcastId，将$this->data['Podcast'][$userId]替换为$userId]
