CakePHP 2: Acl tutorial doesn't work

Question

as the title already says I've got a problem with the Acl Tutorial of CakePHP 2. I've done everything exactly the way it is mentioned in the Tutorial, but still it doesn't work. I know that there are many people on the internet which have also a problem with this tutorial, but I can't find any blog entry or whatever with the same problem like me. When I try to access a direction of my app I get the following error: ``` Notice (8): Undefined index: group_id [APP\Model\User.php, line 98] ``` and: ``` AclNode::node() - Couldn't find Aro node identified by "Array ( [Aro0.model] => Group [Aro0.foreign_key] => ) " ``` So there isn't any value for the foreign_key transmitted to the Acl at all. But the strange thing is that -at least in the functions of the userscontroller- the foreign_key is set properly but when it should be passed to the Acl it is gone ``` Nr Query Error Affected Num. rows Took (ms) 1 SELECT COUNT(*) AS `count` FROM `cake`.`users` AS `User` WHERE `User`.`id` = 4 2 SELECT C…

Accepted Answer

I know its a bit stupid to answer my own question, but instead of deleting the question i think it would be better to leave it here for anybody who has the same problem, because there seems to be no answer for this on the internet.

I was able to solve the problem through the following code:

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

It seems to work perfectly, and maybe it could help some others ;)
