Magento 2: ACL Permission for Admin Module



namespace Custom\Module\Controller\Adminhtml\Posts;

use Magento\Framework\View\Result\PageFactory;
use Magento\Framework\App\Action\Context;

class Index extends \Magento\Framework\App\Action\Action {

     * @var \Magento\Framework\Controller\Result\ForwardFactory
    protected $resultPageFactory;

     * @param \Magento\Framework\App\Action\Context $context
     * @param \Magento\Framework\Controller\Result\ForwardFactory $resultForwardFactory
    public function __construct(
    \Magento\Framework\App\Action\Context $context, \Magento\Framework\View\Result\PageFactory $resultPageFactory
    ) {
        $this->resultPageFactory = $resultPageFactory;

    public function execute() {
        $resultPage = $this->resultPageFactory->create();



        return $resultPage;

     * Check permission via ACL resource

    public function _isAllowed() {
        return $this->_authorization->->isAllowed('Custom_Module::posts');

While calling this it's giving error

Exception #0 (Exception): Notice: Undefined property: Custom\Module\Controller\Adminhtml\Posts\Index\Interceptor::$_authorization in D:\wamp\www\magento\app\code\Custom\Module\Controller\Adminhtml\Posts\Index.php on line 55

Why i'm doing manually, because my Module Permission is still not working. So for Authrization we have module-authorization Module. Would like to use that Manually in Controller/Block file. Ideal Controller.

$_objectManager = \Magento\Framework\App\ObjectManager::getInstance(); //instance of\Magento\Framework\App\ObjectManager
$aclObject  = $_objectManager->get('Magento\Authorization\Model\Acl');

If i use above then it gives Class 'Magento\Authorization\Model\Acl' not found

The controller does not extend Magento\Backend\App\AbstractAction, where _authorization is defined. In a non-admin controller you are not supposed to use the ACL.

About the second part of your question: I am not sure what exactly you want to do with $aclObject, but there really is no class Magento\Authorization\Model\Acl in Magento. Did you mean Magento\Framework\Acl ?

  • Yes. So instead of \Magento\Framework\App\Action\Action need to use Magento\Backend\App\AbstractAction then all works fine? – Ankit Shah Dec 20 '16 at 8:02
  • Theoretically yes. But I also saw your other question and could not find out what's wrong. Good luck! – Fabian Schmengler Dec 20 '16 at 8:05
