@ -77,15 +77,126 @@ Role based access control is very flexible approach to controlling access that i
where permissions are customizable.
In order to start using it some extra steps are required. First of all we need to configure `authManager` application
component:
component in application config file (`web.php` or `main.php` depending on template you've used):
```php
'authManager' => [
'class' => 'app\components\PhpManager',
'defaultRoles' => ['guest'],
],
```
Often use role is stored in the same database table as other user data. In this case we may defined it by creating our
own component (`app/components/PhpManager.php`):
```php
<?php
namespace app\components;
use Yii;
class PhpManager extends \yii\rbac\PhpManager
{
public function init()
{
parent::init();
if (!Yii::$app->user->isGuest) {
// we suppose that user's role is stored in identity
$this->assign(Yii::$app->user->identity->id, Yii::$app->user->identity->role);
}
}
}
```
Then create permissions hierarchy.
Then create permissions hierarchy in `@app/data/rbac.php`:
```php
<?php
use yii\rbac\Item;
return [
// HERE ARE YOUR MANAGEMENT TASKS
'manageThing0' => ['type' => Item::TYPE_OPERATION, 'description' => '...', 'bizRule' => NULL, 'data' => NULL],
'manageThing1' => ['type' => Item::TYPE_OPERATION, 'description' => '...', 'bizRule' => NULL, 'data' => NULL],
'manageThing2' => ['type' => Item::TYPE_OPERATION, 'description' => '...', 'bizRule' => NULL, 'data' => NULL],
'manageThing2' => ['type' => Item::TYPE_OPERATION, 'description' => '...', 'bizRule' => NULL, 'data' => NULL],
// AND THE ROLES
'guest' => [
'type' => Item::TYPE_ROLE,
'description' => 'Guest',
'bizRule' => NULL,
'data' => NULL
],
'user' => [
'type' => Item::TYPE_ROLE,
'description' => 'User',
'children' => [
'guest',
'manageThing0', // User can edit thing0
],
'bizRule' => 'return !Yii::$app->user->isGuest;',
'data' => NULL
],
'moderator' => [
'type' => Item::TYPE_ROLE,
'description' => 'Moderator',
'children' => [
'user', // Can manage all that user can
'manageThing1', // and also thing1
],
'bizRule' => NULL,
'data' => NULL
],
'admin' => [
'type' => Item::TYPE_ROLE,
'description' => 'Admin',
'children' => [
'moderator', // can do all the stuff that moderator can
'manageThing2', // and also manage thing2
],
'bizRule' => NULL,
'data' => NULL
],
'godmode' => [
'type' => Item::TYPE_ROLE,
'description' => 'Super admin',
'children' => [
'admin', // can do all that admin can
'manageThing3', // and also thing3
],
'bizRule' => NULL,
'data' => NULL
],
];
```
Now you can specify roles from RBAC in controller's access control configuration:
```php
public function behaviors()
{
return [
'access' => [
'class' => 'yii\web\AccessControl',
'except' => ['something'],
'rules' => [
[
'allow' => true,
'roles' => ['manageThing1'],
],
],
],
];
}
```
Specify roles from RBAC in controller's access control configuration or call [[User::checkAccess()]] where appropriate.
Another way is to call [[User::checkAccess()]] where appropriate.

Using RBAC
===========
Lacking proper documentation, this guide is a stub copied from a [topic on the forum](http://www.yiiframework.com/forum/index.php/topic/49104-does-anyone-have-a-working-example-of-rbac/page__view__findpost__p__229098).
First af all, you modify your config (web.php or main.php),
```php
'authManager' => [
'class' => 'app\components\PhpManager', // THIS IS YOUR AUTH MANAGER
'defaultRoles' => ['guest'],
],
```
Next, create the manager itself (app/components/PhpManager.php)
```php
<?php
namespace app\components;
use Yii;
class PhpManager extends \yii\rbac\PhpManager
{
public function init()
{
if ($this->authFile === NULL)
$this->authFile = Yii::getAlias('@app/data/rbac') . '.php'; // HERE GOES YOUR RBAC TREE FILE
parent::init();
if (!Yii::$app->user->isGuest) {
$this->assign(Yii::$app->user->identity->id, Yii::$app->user->identity->role); // we suppose that user's role is stored in identity
}
}
}
```
Now, the rules tree (@app/data/rbac.php):
```php
<?php
use yii\rbac\Item;
return [
// HERE ARE YOUR MANAGEMENT TASKS
'manageThing0' => ['type' => Item::TYPE_OPERATION, 'description' => '...', 'bizRule' => NULL, 'data' => NULL],
'manageThing1' => ['type' => Item::TYPE_OPERATION, 'description' => '...', 'bizRule' => NULL, 'data' => NULL],
'manageThing2' => ['type' => Item::TYPE_OPERATION, 'description' => '...', 'bizRule' => NULL, 'data' => NULL],
'manageThing2' => ['type' => Item::TYPE_OPERATION, 'description' => '...', 'bizRule' => NULL, 'data' => NULL],
// AND THE ROLES
'guest' => [
'type' => Item::TYPE_ROLE,
'description' => 'Guest',
'bizRule' => NULL,
'data' => NULL
],
'user' => [
'type' => Item::TYPE_ROLE,
'description' => 'User',
'children' => [
'guest',
'manageThing0', // User can edit thing0
],
'bizRule' => 'return !Yii::$app->user->isGuest;',
'data' => NULL
],
'moderator' => [
'type' => Item::TYPE_ROLE,
'description' => 'Moderator',
'children' => [
'user', // Can manage all that user can
'manageThing1', // and also thing1
],
'bizRule' => NULL,
'data' => NULL
],
'admin' => [
'type' => Item::TYPE_ROLE,
'description' => 'Admin',
'children' => [
'moderator', // can do all the stuff that moderator can
'manageThing2', // and also manage thing2
],
'bizRule' => NULL,
'data' => NULL
],
'godmode' => [
'type' => Item::TYPE_ROLE,
'description' => 'Super admin',
'children' => [
'admin', // can do all that admin can
'manageThing3', // and also thing3
],
'bizRule' => NULL,
'data' => NULL
],
];
```
As a result, you can now add access control filters to controllers
```php
public function behaviors()
{
return [
'access' => [
'class' => 'yii\web\AccessControl',
'except' => ['something'],
'rules' => [
[
'allow' => true,
'roles' => ['manageThing1'],
],
],
],
];
}
```
