Module getServiceConfig not injecting TableGateway into repository - php

Question

I can't seem to get my table gateway to inject into my repository(service)...
I have the following:
Module.php:
public function getConfig()
{
return include __DIR__ . '/config/module.config.php';
}
public function getServiceConfig()
{
return array(
'factories' => array(
'Album\Model\Concrete\AlbumRepository' => function($sm) {
$tableGateway = $sm->get('AlbumTableGateway');
$table = new AlbumRepository($tableGateway);
return $table;
},
'AlbumTableGateway' => function ($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$resultSetPrototype = new ResultSet();
$resultSetPrototype->setArrayObjectPrototype(new Album());
return new TableGateway('albums', $dbAdapter, null, $resultSetPrototype);
}
)
);
}
and here is my module.config.php:
return array(
'service_manager' => array(
'invokables' => array(
'Album\Model\Abstracts\IAlbumRepository' => 'Album\Model\Concrete\AlbumRepository'
),
),
'controllers' => array(
'factories' => array(
'Album\Controller\Album' => 'Album\Model\Factories\AlbumControllerFactory',
),
),
the error is:
Catchable fatal error: Argument 1 passed to Album\Model\Concrete\AlbumRepository::__construct() must be an instance of Zend\Db\TableGateway\TableGateway, none given, called in C:\xampp\htdocs\ZendFrameworkTest\vendor\zendframework\zendframework\library\Zend\ServiceManager\ServiceManager.php on line 1035 and defined in C:\xampp\htdocs\ZendFrameworkTest\module\Album\src\Album\Model\Concrete\AlbumRepository.php on line 11
Note:
the delegate functions on the factories array are just not getting called, i'm doing somethign silly but i can't tell what.
I'm also doing dependancy injection, i'm guessing this is where it's going wrong as the factory is creating the repository object without the injection:
class AlbumControllerFactory implements FactoryInterface
{
/**
* Create service
*
* #param ServiceLocatorInterface $serviceLocator
*
* #return mixed
*/
public function createService(ServiceLocatorInterface $serviceLocator)
{
// Need to do something here?
$realServiceLocator = $serviceLocator->getServiceLocator();
$postService = $realServiceLocator->get('Album\Model\Abstracts\IAlbumRepository');
return new AlbumController($postService);
}
}

Answer 1

You defined your repository as invokable, that means that service manager tries to create it by instantiating directly without any params.
change it to alias
return array(
'service_manager' => array(
'aliases' => array(
'Album\Model\Abstracts\IAlbumRepository' => 'Album\Model\Concrete\AlbumRepository'
),
),
);
