Yii RBAC Rules Container

This package is a factory for creating Yii RBAC (Role-Based Access Control) rules. It provides rules container based on Yii Factory and uses Yii Definitions syntax. RBAC manager accepts rule as a name and parameters and is unaware of its creation by design, delegating creation to rules container keeping responsibilities separation.

Requirements

• PHP 8.1 or higher.

Installation

The package could be installed with Composer:

composer require yiisoft/rbac-rules-container

General usage

Direct interaction with rules container

use Psr\Container\ContainerInterface;
use Yiisoft\Rbac\Item;
use Yiisoft\Rbac\RuleInterface;
use Yiisoft\Rbac\Rules\Container\RulesContainer;

/**
 * Checks if user ID matches `authorID` passed via parameters.
 */
final class AuthorRule implements RuleInterface
{
    public function execute(string $userId, Item $item, array $parameters = []): bool
    {
        return $parameters['authorID'] === $userId;
    }
}

$rulesContainer = new RulesContainer(new MyContainer());
$rule = $rulesContainer->create(AuthorRule::class);

• MyContainer is a container for resolving dependencies and must be an instance of Psr\Container\ContainerInterface. Yii Dependency Injection implementation also can be used.
• You can optionally set definitions and disable their validation if needed.

Basically, the arguments are the same as in Yii Factory. Please refer to its docs for more details.

Rules are created only once, then cached and reused for repeated calls.

$rule = $rulesContainer->create(AuthorRule::class); // Returned from cache

Using Yii config

use Yiisoft\Di\Container;
use Yiisoft\Di\ContainerConfig;
use Yiisoft\Rbac\RuleFactoryInterface;
use Yiisoft\Rbac\Rules\Container\RulesContainer;

// Need to be moved to separate files accordingly
$params = [
    'yiisoft/rbac-rules-container' => [
        'rules' => ['author' => AuthorRule::class],
        'validate' => false,
    ],
];
$config = [
    RuleFactoryInterface::class => [
        'class' => RulesContainer::class,
        '__construct()' => [
            'definitions' => $params['yiisoft/rbac-rules-container']['rules'],
            'validate' => $params['yiisoft/rbac-rules-container']['validate'],
        ],
    ],
];          
$containerConfig = ContainerConfig::create()->withDefinitions($config); 
$container = new Container($containerConfig);
$rulesContainer = $container->get(RuleFactoryInterface::class);        
$rule = $rulesContainer->create('author');
