A Laminas module to enable selectively populating Laminas ACL at query time

Sometimes your project has a LOT of roles, resources and rules. This module has plugin managers for those things, and only requests and loads into the ACL the minimum objects needed to answer a query.

Installation

Installation of this module uses composer. For composer documentation, please refer to getcomposer.org.

composer require riddlestone/brokkr-acl

Usage

This module adds four plugin managers, your module/project can provide configuration to any of these.

RoleManager

To provide roles for the ACL, implement Laminas\ServiceManager\FactoryInterface, and then add your class to the acl_role_manager config:

<?php
return [
    'acl_role_manager' => [
        'abstract_factories' => [
            'My\\Factory',
        ],
    ],
];

When the ACL requires a role, your factory will be asked if it can provide it.

RoleRelationshipManager

To allow projects and modules to define the relationship between roles, the role relationship manager gathers information about the parents of a given role.

To provide parentage information about roles, implement RoleRelationshipProviderInterface, and register the class as a provider in the acl_role_relationship_manager config:

<?php
return [
    'acl_role_relationship_manager' => [
        'factories' => [
            'My\\Provider' => 'My\\Provider\\Factory',
        ],
        'providers' => [
            'My\\Provider',
        ],
    ],
];

Specifying the providers separately from the factories which produce them allow us to use providers which are created through abstract factories, or otherwise injected into the plugin manager.

ResourceManager

To provide resources for the ACL, implement Laminas\ServiceManager\FactoryInterface, and then add your class to the acl_resource_manager config:

<?php
return [
    'acl_resource_manager' => [
        'abstract_factories' => [
            'My\\Factory',
        ],
    ],
];

When the ACL requires a resource, your factory will be asked if it can provide it.

RuleManager

To allow projects and modules to specify permissions, the rule manager gathers information about which rules apply to given roles and resources.

To provide rules, implement RuleProviderInterface, and register the class as a provider in the acl_rule_manager config:

<?php
return [
    'acl_rule_manager' => [
        'factories' => [
            'My\\Provider' => 'My\\Provider\\Factory',
        ],
        'providers' => [
            'My\\Provider',
        ],
    ],
];

Specifying the providers separately from the factories which produce them allow us to use providers which are created through abstract factories, or otherwise injected into the plugin manager.

Querying the ACL

Once all the managers are configured, you can query the ACL by pulling it from the ServiceManager, and calling isAllowed():

<?php
use Laminas\ServiceManager\ServiceManager;
use Riddlestone\Brokkr\Acl\Acl;
/**
 * @var ServiceManager $serviceManager
 */
$acl = $serviceManager->get(Acl::class);
$isAllowed = $acl->isAllowed('some_role', 'a_resource', 'view');
