How can I access database inside zend framework 2 plugin - doctrine-orm

Question

I need to access database inside zend framework2 plugin. I have to create ACL using database and for this purpose I need to access database inside plugin.
Here is my module.config.php
return array(
// added for Acl ###################################
'controller_plugins' => array(
'invokables' => array(
'MyAclPlugin' => 'MyAcl\Controller\Plugin\MyAclPlugin',
)
),
// end: added for Acl ###################################
);
Here is my module.php
namespace MyAcl;
use Zend\ModuleManager\ModuleManager; // added for module specific layouts. ericp
// added for Acl ###################################
use Zend\Mvc\MvcEvent,
Zend\ModuleManager\Feature\AutoloaderProviderInterface,
Zend\ModuleManager\Feature\ConfigProviderInterface;
// end: added for Acl ###################################
//class Module
class Module {
public function getConfig() {
return include __DIR__ . '/config/module.config.php';
}
// added for Acl ###################################
public function onBootstrap(MvcEvent $e) {
$eventManager = $e->getApplication()->getEventManager();
$eventManager->attach('route', array($this, 'loadConfiguration'), 2);
//you can attach other function need here...
}
public function loadConfiguration(MvcEvent $e) {
$application = $e->getApplication();
$sm = $application->getServiceManager();
$sharedManager = $application->getEventManager()->getSharedManager();
$router = $sm->get('router');
$request = $sm->get('request');
$matchedRoute = $router->match($request);
if (null !== $matchedRoute) {
$sharedManager->attach('Zend\Mvc\Controller\AbstractActionController', 'dispatch', function($e) use ($sm) {
$sm->get('ControllerPluginManager')->get('MyAclPlugin')
->doAuthorization($e); //pass to the plugin...
}, 2
);
}
}
// end: added for Acl ###################################
/*
* // added init() func for module specific layouts. ericp
* http://blog.evan.pro/module-specific-layouts-in-zend-framework-2
*/
public function init(ModuleManager $moduleManager) {
$sharedEvents = $moduleManager->getEventManager()->getSharedManager();
$sharedEvents->attach(__NAMESPACE__, 'dispatch', function($e) {
// This event will only be fired when an ActionController under the MyModule namespace is dispatched.
$controller = $e->getTarget();
//$controller->layout('layout/zfcommons'); // points to module/Album/view/layout/album.phtml
}, 100);
}
public function getAutoloaderConfig() {
return array(
'Zend\Loader\ClassMapAutoloader' => array(
__DIR__ . '/autoload_classmap.php',
),
'Zend\Loader\StandardAutoloader' => array(
'namespaces' => array(
__NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,
),
),
);
}
}
And my plugin MyAclPlugin.php
I need to access some table (role, resource) from plugin, so that I can configure this resource allocation using a UI. Is there anyway I can access database from plugin. Please let me know the process.
namespace MyAcl\Controller\Plugin;
use Zend\Mvc\Controller\Plugin\AbstractPlugin,
Zend\Session\Container as SessionContainer,
Zend\Permissions\Acl\Acl,
Zend\Permissions\Acl\Role\GenericRole as Role,
Zend\Permissions\Acl\Resource\GenericResource as Resource;
use Zend\View\Model\JsonModel;
use DataSource\Model\AgentModel;
use DataSource\Model\OfficeModel;
use DataSource\Model\UserModel;
class MyAclPlugin extends AbstractPlugin{
protected $constants;
protected $userModel;
protected $agentModel;
protected $user;
protected $sesscontainer;
private function getSessContainer() {
if (!$this->sesscontainer) {
$this->sesscontainer = new SessionContainer('zftutorial');
}
return $this->sesscontainer;
}
public function doAuthorization($e) {
$acl = new Acl();
$acl->deny();
//$this->createService();

Please let me know how can I do that.

Answer 1

In your "MyAclPlugin" create a method like:
public function setServiceLocator($sl)
{
$this->sl = $sl;
}
Then in your MyAcl module.php create a method:
public function getServiceConfig()
{
return array(
'factories' => array(
'myAclPlugin' => function($sm)
{
$plugin = new Controller\Plugin\MyAclPlugin();
$plugin->setServicelocator($sm);
return $plugin;
},
),
);
}
Then in your MyAclPlugin you could probably do something like:
$dbAdapter = $this->sl->get('Zend\Db\Adapter\Adapter');
Hope this helps

Answer 2

In reference to the previous answer from Peter you could implement the ServiceLocatorAwareInterface in your Plugin, so you can use $this->getServiceocator() in it.
This method should return a class like ControllerPluginManager. From this you must be able to call getService(Manager|Locator) (i'm not sure right now) to get the top-level ServiceManager that knows everything about all ServiceManagers. There you should be able to call get('Zend\Db\Adapter\Adapter').
But some ZF2 maintainer are sure that this technique is bad practise (see Github issue)
