DbAcl::allow() – Invalid node [CORE\cake\libs\controller\components\acl.php, line 325]

Did you try it? Looks like it doesn’t work. I have this problem but it didn’t help me.

I didn’t solve it, I only used shell version, it works perfectly for the same things.

But now I have another problem.
I have this warning message when I try to log in:
Warning (512): DbAcl::check() – Failed ARO/ACO node lookup in permissions check.

My login function exactly the same what in the tutorial (http://book.cakephp.org/).

Can you help me with this?

I tried using this in my users controller: http://bin.cakephp.org/view/1547890968, but get the same error.

Hi
thanks for help.
now my authentication works perfectly.
my first problem was that I didn’t properly fill tables aros and acos and tried to fill table aros_acos.
And I had second warning
Warning (512): DbAcl::check() – Failed ARO/ACO node lookup in permissions check.
because in table acos I put only controllers, but we should put actions too which have parent_id = their controllers.

p.s. sorry for my bad english, I hope my words are clear.

Thanks!!!!

This saved me many hours of work tonight!

Worked perfect thanks!

The setting up permission page is a rather difficult page to read.
The top section that reads
“Creating permissions much like creating ACO’s has no magic solution, nor will I be providing one. To allow ARO’s access to ACO’s from the shell interface use the AclShell. For more information on how to use it consult the aclShell help which can be accessed by running:”

Do we have to figure out how to set these permissions before moving on to the rest of the page?

Next:
what does this mean
“To allow with the AclComponent do the following:
$this->Acl->allow($aroAlias, $acoAlias);”
and where does this line go?

Next:
I changed the line as you said above in the initDB function but i am still getting the error.

Any help would be great. Thanks so much

right after posting i realized that the tutorial says to add the iniDB function to the users controller. I had added it to the groups controller.
now my aro_aco table has lots of 1′s and -1′s. the tutorial says it should have lots of 1′s and 0′s.
should it be -1 or 0?

If I am not mistaken, the -1 in questions is actually a deny(). In my case, it is created by use of this statement:

$this->Acl->deny($group, ‘controllers’);

I’m about to do your tutorial as I am having the same error. Will update with my results!

Hi there, thanks for the heads up on this one. Just in case any one else had the same error as me, I found that the build_acl script that is found on the Cakephp site adds an extra ‘controller’ actino to the ‘Users’ in the aco table.

This meant that even with this workaround, as soon as I tried to deny a usergroup from controllers/Users/delete, I was getting an error again. I don’t have an action in the users_controller called controllers so this is a very strange one. I am using cakephp 1.3 and had no problems with 1.2 on this subject.

I removed the Users/controllers from the acl and then it worked, using the above array as the first parameter.

I was getting the following error even though the user had been wiped from my DB. Ran it in a different browser and the problem went so must be a caching issue. Tried the suggestions above but that didn’t help.

I use :

$this->Acl->allow(array(‘model’=>’Group’, ‘foreign_key’=>’1′), ‘controllers’);

But it doesn’t work

Please help

Thanks, this tutorial saves my day, if someone failed when try this tutorial, please try to remove $group->id = from function initDB()and use array like this tutorial explained.
