How to add role to user? - php

Question

We used Yii2 framework last alpha. Role for user already created but problem is how it assign to user. Documentation is absent.

Answer 1

For database version of RBAC use DbManager (quote frm: Alexufo):
use yii\rbac\DbManager;
$r=new DbManager;
$r->init();
$r->createRole("admin","Administrator");
$r->save();
$r->assign('1','admin'); //1 is user id
Example Access rules:
<?php
namespace backend\controllers;
use yii;
use yii\web\AccessControl;
use yii\web\Controller;
class SiteController extends Controller
{
public function behaviors()
{
return [
'access' => [
'class' => AccessControl::className(),
'rules' => [
[
//'actions' => ['login', 'error'], // Define specific actions
'allow' => true, // Has access
'roles' => ['#'], // '#' All logged in users / or your access role e.g. 'admin', 'user'
],
[
'allow' => false, // Do not have access
'roles'=>['?'], // Guests '?'
],
],
],
];
}
public function actionIndex()
{
return $this->render( 'index' );
}
}
?>
Don't forget to add this to your configuration file (config/main.php):
'components' => [
'authManager'=>array(
'class' => 'yii\rbac\DbManager',
'defaultRoles' => ['end-user'],
),
...
]
Tables:
drop table if exists `tbl_auth_assignment`;
drop table if exists `tbl_auth_item_child`;
drop table if exists `tbl_auth_item`;
create table `tbl_auth_item`
(
`name` varchar(64) not null,
`type` integer not null,
`description` text,
`biz_rule` text,
`data` text,
primary key (`name`),
key `type` (`type`)
) engine InnoDB;
create table `tbl_auth_item_child`
(
`parent` varchar(64) not null,
`child` varchar(64) not null,
primary key (`parent`,`child`),
foreign key (`parent`) references `tbl_auth_item` (`name`) on delete cascade on update cascade,
foreign key (`child`) references `tbl_auth_item` (`name`) on delete cascade on update cascade
) engine InnoDB;
create table `tbl_auth_assignment`
(
`item_name` varchar(64) not null,
`user_id` varchar(64) not null,
`biz_rule` text,
`data` text,
primary key (`item_name`,`user_id`),
foreign key (`item_name`) references `tbl_auth_item` (`name`) on delete cascade on update cascade
) engine InnoDB;
You can also find this information in the "yii/rbac" directory (including other SQL files).

Answer 2

$user_id = 1;
$auth = new DbManager;
$auth->init();
$role = $auth->createRole('editor');
$auth->add($role);
$auth->assign($role, $user_id);
=========================================================================
if you want to select role instead creating then
$auth = new DbManager;
$auth->init();
$role = $auth->getRole('admin');
$auth->assign($role, $user_id);
100% worked!

================ create role ============

$r->assign('1','admin'); //1 is user id

A really simple way to achieve an admin role is to add this to your controller:
use yii;
/**
* #inheritdoc
*/
public function behaviors()
{
return [
'access' => [
'class' => AccessControl::className(),
'rules' => [
[
'allow' => true,
'actions' => ['index'],
'roles' => ['#'],
],
[
'allow' => !Yii::$app->user->isGuest && Yii::$app->user->identity->isAdmin(),
'actions' => ['view', 'create', 'update', 'delete'],
],
],
],
];
}
Then add to your User model an isAdmin() which returns true for your admin user(s) and false for everyone else. Personally, I use:
public function isAdmin() {
return Self::ROLE_ADMIN === $this->role;
}
Admittedly, this is not "by the book". But it is simple, quick and effective.

$user_id = \Yii::$app->user->id;
$auth = new DbManager;
$auth->init();
$role = $auth->createRole('editor');
$auth->add($role);
$auth->assign($role, $user_id);
