CakePHP ACL: Optional ACO Node (allow by default)

I'm making a CakePHP app using a modified version of database ACL.

In order to avoid having to create ACO nodes for every single controller, I would like to establish a system whereby users are allowed access to a page unless otherwise denied. This means that I don't want to create ACO nodes for controllers unless absolutely necessary.

Normally, if I fail to create an ACO node, when my isAuthorised() function performs $this->Acl->check, I get an error such as this...

Warning (512): DbAcl::check() - Failed ARO/ACO node lookup in permissions check.  Node references:
Aro: Array
(
    [model] => Role
    [foreign_key] => 1
)

I think a feasible solution would be to check if the ACO node exists before performing a $this->Acl->check command. If it doesn't exist, then it would be possible to stop it from checking permissions.

Is there a way to check out if an ACO node exists, based on the output of $this->Auth->action() (which outputs something like controllers/Members/Edit)?

My Auth ActionPath is set to 'controllers'.

Or maybe there开发者_运维问答 is a better way of going about it?

I hope I have phrased my question adequately, I will ensure to clarify if not.

Thanks!

You can use this to check if the Aco exists.

if($this->Acl->Aco->node('controllers/Members/Edit')) {
    debug('Aco exists!');
}

If you want to use ACL component you must have ARO and ACO trees. Otherwise there is no sense to use that component.

I would suggest you to create a super-user for all users, allow him to access all ACO nodes, but deny specific ACO nodes. So, all users would inherit the permissions from that abstract super-user. I guess you have studied Simple Acl controlled Application tutorial, haven't you?

Another option would be to use Auth component and write your own permissions handling component. There are many tutorials how to build admin panel.

Solved this by making an edit to the core ACL.php file, there was no normal solution.
