AclExtras Warning Error

Question

In CakePHP 2 book / Acl Tutorial / Part 2, I am executing the command:

./Console/cake AclExtras.AclExtras aco_sync

and I get a warning error:

Warning Error: Argument 1 passed to Component::startup() must be an instance of Controller, 
null given, called in 
/opt/lampp/htdocs/acl/app/Plugin/AclExtras/Console/Command/AclExtrasShell.php 
on line 80 and defined in [/opt/lampp/htdocs/acl/lib/Cake/Controller/Component.php, line 119]

The acos table gets populated with NULL in model field and NULL in all fields of the foreign_key.

How can I fix this error?

Answer 1

in AclExtras/Console/Command, please change startup function to :

public function startup() {
    parent::startup();
    $controller = new Controller();
    $collection = new ComponentCollection();
    $this->Acl = new AclComponent($collection);
    $this->Acl->startup($controller);
    $this->Aco = $this->Acl->Aco;
}
