RBAC in Yii2 with PhpManager - yii2

Question

How can I implement RBAC in Yii 2.0 without any database.
I will have just 2 roles , i.e. admin and author .
my RbacController is
<?php
namespace app\commands;
use Yii;
use yii\console\Controller;
class RbacController extends Controller
{
public function actionInit()
{
$auth = \Yii::$app->authManager;
// add "createPost" permission
$createPost = $auth->createPermission('createPost');
$createPost->description = 'Create a post';
$auth->add($createPost);
// add "updatePost" permission
$updatePost = $auth->createPermission('updatePost');
$updatePost->description = 'Update post';
$auth->add($updatePost);
// add "author" role and give this role the "createPost" permission
$author = $auth->createRole('author');
$auth->add($author);
$auth->addChild($author, $createPost);
// add "admin" role and give this role the "updatePost" permission
// as well as the permissions of the "author" role
$admin = $auth->createRole('admin');
$auth->add($admin);
$auth->addChild($admin, $updatePost);
$auth->addChild($admin, $author);
// Assign roles to users. 1 and 2 are IDs returned by IdentityInterface::getId()
// usually implemented in your User model.
$auth->assign($author, 2);
$auth->assign($admin, 1);
}
}
I am getting an error
`PHP Fatal error: Call to a member function createPermission()
on a non-object in var/www/commands/RbacController.php on line 14
PHP Fatal Error 'yii\base\ErrorException' with message 'Call to a member
function createPermission() on a non-object' in /var/www/commands/RbacController.php:14
while executing yii rbac/init . I am using basic template with PhpManager . I have added 'authManager' => [ 'class' => 'yii\rbac\PhpManager', ], in web.php .I am using basic template.

i Know this is a bit old, but I want to publish the solution.. at least what worked for me.
I have added 'authManager' => [ 'class' => 'yii\rbac\PhpManager', ],
in web.php
There is the mistake, since you a re running the command via console, you need to add that same line in the components section of console.php (in the same directory as web.php).
I hope this helps others who have a similar problem :D

The official documentation actually uses a php file https://github.com/yiisoft/yii2/blob/master/docs/guide/security-authorization.md

try this in your controller
$auth = new \yii\rbac\PhpManager();
// add "createPost" permission
$createPost = $auth->createPermission('createPost');
$createPost->description = 'Create a post';
$auth->add($createPost);
