RBAC help needed

Yii 2.0 General Discussions
21

Dear Friends thank you for your detailed discussion.

I have one doubt.I read most of the docs .But i couldn’t understand may be because of i’m new to yii2

Suppose we have 3 types of logged in users Admin,Creator and Editor

I need to restrict creator to edit and delete

I need to restrict editor to create and delete

Admin can create ,edit and delete

so these are my actions

public function actionCreate(){ }

public function actionUpdate($id) { }

public function actionDelete($id) { }

Do i add anything on behaviour or beforeaction or call function like Can() ?

if so how :(

Best regards :)

I’m just using the behaviors() and it is working for me…

I did not use the can() function yet…

from what you said:




public function behaviors()

    {

        return [

            'access' => [

                'class' => AccessControl::className(),

                'only' => ['create', 'update', 'delete'],

                'rules' => [

                    [

                        'allow' => false,

                        'actions' => ['update', 'delete'],

                        'roles' => ['Creator'], // roles affected by the rules

                    ],

                    [

                        'allow' => false,

                        'actions' => ['create', 'delete'],

                        'roles' => ['Editor'], 

                    ],

                    [

                        'allow' => true,

                        'actions' => ['create', 'update', 'delete'],

                        'roles' => ['Admin'], // admin can access delete action

                    ],

                ],

            ],

        ];

    }

if I’m wrong in anything I’m sorry, but I can bet that you can copy/past this :P

Im following the RBAC Guide, and there seems to be something missing. Namely, when I run the "yii rbac/init" command, I get the following error:


PHP Warning 'yii\base\ErrorException' with message 'Invalid argument supplied for foreach()'


in /var/www/site/vendor/yiisoft/yii2/rbac/PhpManager.php:641


Stack trace:

#0 /var/www/site/vendor/yiisoft/yii2/rbac/PhpManager.php(641): yii\base\ErrorHandler->handleError(2, 'Invalid argumen...', '/var/www/site/v...', 641, Array)

This looks like it happens when PhpManager tries to load $items. My backend/rbac/items.php file is blank, since I havent run this migration yet.

Has anyone else run into this error? Ive pretty much followed the guide exactly as it is written. What am I missing? What needs to go in items.php for PhpManager to work? What information is missing from the guide?

------- update -----------

after reading all the source code for everything rbac (w/ PhpManager), i realized there are some steps to the guide that are a bit misleading. i had already created a blank items.php, assignments.php, and roles.php before i created the console command (RbacController). once i deleted these files, the console command i made worked as expected.
