Zend Framework 2 passes a variable to a model

I am currently developing a multilingual website. For the multilingual part, I use the / poedit translator. I store the selected language in the session. It works great.

module.php:

public function onBootstrap(MvcEvent $e)
{
    // ...

    $session = new Container('base');

    if ($session->language !== NULL) {
        $e->getApplication()->getServiceManager()->get('translator')->setLocale($session->language);
    }
}

Action for setting the language in the controller:

public function setLanguageAction()
{
    $language = $this->params()->fromRoute('language');

    if (isset($this->languages[$language])) {

        $session = new Container('base');

        if ($language == 'en') {
            $session->language = NULL;
        } else {
            $session->language = $language;
        }
    }

    return $this->redirect()->toRoute('home');
}

In module.config.php, the locale is set to en by default.

Like I said, everything works fine, except for one.

I also store some language-specific data in DB, so in my models I need to know what the current language is. The current language is also needed for other purposes in models.

So, I include the following code in each design function of the model:

$session = new Container('base');

if ($session->language !== NULL) {
    $this->language = $session->language;
} else {
    $this->language = 'default';
}

I think this is not the best solution. I have too many models to always include this code.

, $language , , Module.php/getServiceConfig:

public function getServiceConfig()
{        
    $session = new Container('base');

    return array(
        'factories' => array(
            'Application\Model\SomeThing' => function($sm) {
                $dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
                $c = new SomeThing($dbAdapter);
                $c->language = $session->language;
                return $c;
            }
        )
    );
}
