Yes you're right, jeremy, I made this example up (my real User model
doesn't have an Address, I just added this to show that there are
cases where there's more than one key that isn't another array
itself).
The reason why I'd like to know this is the following.
I have implemented a simple ACL component that delivers an ActiveUser
object to the views which can be asked for permissions for certain
things:
// In the view...
<li><?php if($usr->allowed('Users', 'edit')) echo
$this->Html->link(__('Edit User', true), array('action' => 'edit',
$post['User']['id'])); ?> </li>
This works great so far, but it only works on the controller/action level.
Every user is in a group which provides an ACL access string like
"!*:*,*:index,*:view" for guests or "!*:*,Users:*" for users editors
or "*:*" for administrators. So with the functionality above, only
administrators can edit users. But I'd also like my users to be able
to edit their own user data.
So I thought of an extended $usr->allowed(...) version which also
accepts a model instance like the following:
$usr->allowed('edit', $userInstance) // $userInstance is not the data
array, but a real "new User()" instance
Then in the User::allowed(...) method I can ask the model instance
itself whether it wants to allow something or not:
function allowed
if(last param is model object)
return modelObject->allows($action, $this->id)
else
do normal ACL string stuff...
}
So I can implement an allows(...) method in every model I'd like to
have authorisation functionality on a model instance level:
// In the model...
function allows($action, $userId)
return $this->user_id == $userId // If the user is the same like the
one who owns the record, then let him edit it!
This works great so far, too. But because CakePHP doesn't deliver
views with real model instances but only data arrays, I'd like to be
able to pass them to the allowed(...) method, too. There I only have
to re-create the model instance, so I can ask it for allowance. And
here's the problem: it seems there can't be known what model a data
array originated from... Or can there? :-)
Thanks for help... (and sorry for the long explanation...)
