acl权限

Question

使用蛋糕acl，我尝试为已登录的用户设置权限。我在登录函数中有以下内容：

if ($user = $this->Auth->user()) {
    CakeLog::write('debug', 'this->Auth->user');
    //debug($user['User']);
    $userGroup = $this->User->Group->findById($user['User']['group_id']);
    $aro = $this->Acl->Aro->find('first', array(
        'conditions' => array(
            'Aro.model' => 'Group',
            'Aro.foreign_key' => $this->_user['User']['group_id'],  
        ),
    ));
    $acos = $this->Acl->Aco->children();
    foreach ($acos as $aco) {
    $permission = $this->Acl->Aro->Permission->find('first', array(
        'conditions' => array(
            'Permission.aro_id' => $aro['Aro']['id'],
            'Permission.aco_id' => $aco['Aco']['id'],
        ),
    ));
    if (isset($permission['Permission']['id'])) {
        if ($permission['Permission']['_create'] == 1 ||
            $permission['Permission']['_read'] == 1 ||
            $permission['Permission']['_update'] == 1 ||
            $permission['Permission']['_delete'] == 1) {
                $this->Session->write(
                    'Auth.Permissions.' . $permission['Aco']['alias'], true
                );
                if (!empty($permission['Aco']['parent_id'])) {
                    $parentAco = $this->Acl->Aco->find('first', array(
                        'conditions' => array(
                            'id' => $permission['Aco']['parent_id']
                        )
                    ));
                    $this->Session->write(
                        'Auth.Permissions.' . $permission['Aco']['alias']
                        . '.' . $parentAco['Aco']['alias'], true
                    );
                }
            }
        }
    }
}

我得到了这个错误：

未定义的属性: UsersController::$_user APP\controllers\users_controller.php，第82行

我可以用'$this->_user'User'‘修改’$this->_user‘user’，这样做对吗？如果不是，我应该设置什么公共$_user =？

谢谢

Answer 1

我用$user替换了_user，它似乎可以工作。

Answer 2

如果需要经过身份验证的用户的group_id，可以调用

AuthComponent::user('group_id');
