Question

正如标题所说，我对CakePHP 2的Acl教程有疑问。我完全按照教程中提到的方式完成了所有工作，但它仍然不起作用。

我知道互联网上有很多人也有本教程的问题，但我找不到任何博客条目或其他像我一样的问题。当我尝试访问我的应用程序的方向时，我收到以下错误：

Notice (8): Undefined index: group_id [APP\Model\User.php, line 98]

和

AclNode::node() - Couldn't find Aro node identified by "Array ( [Aro0.model] => Group [Aro0.foreign_key] => ) "

因此，传递给Acl的foreign_key根本没有任何值。但奇怪的是 - 至少在用户控制器的功能中 - foreign_key设置正确但是当它应该传递给Acl时它已经消失了

错误消息中的行是：

public function bindNode($user) {
    return array('model'=>'Group','foreign_key'=>$user['User']['group_id']);
}

那么为什么foreign_key的值首先是“2”（它应该如何）以及之后的NULL？

我希望你们中的一些人能够帮助我。感谢。

PS：对于那些更喜欢我的问题的德语版本的人，here它是

更新我能够通过以下方式使其适用于用户控制器的所有功能：

public function bindNode() {
    $this->id;
    $data = $this->read();
    return array('model' => 'Group', 'foreign_key' => $data['User']['group_id']);
    }

但对于所有其他控制器，它仍然是相同的.. 有没有人知道如何在模型中获取用户数据，以便它也适用于其他控制器？

Answer 1

我知道回答我自己的问题有点愚蠢，但我没有删除这个问题，我认为最好把它留给任何有同样问题的人，因为似乎没有答案互联网。

我能够通过以下代码解决问题：

public function bindNode() {
    $data = AuthComponent::user();
    return array('model' => 'Group', 'foreign_key' => $data['User']['group_id']);
    }

它似乎完美无缺，也许它可以帮助其他人;）
