Phalcon PHP - attach event manager to router in non-micro app without rolling my own EventsManager

I'm trying to add something like this into a non-micro app, but I'm unsure of how to go about doing that without rolling my own EventsManager. Is there a way to get a reference to Phalcon's default EventsManager?

$eventsManager->attach("dispatch", function($event, $dispatcher, $exception) {

    if ($event->getType() == 'beforeException') {
        switch ($exception->getCode()) {
            case Phalcon\Dispatcher::EXCEPTION_HANDLER_NOT_FOUND:
            case Phalcon\Dispatcher::EXCEPTION_ACTION_NOT_FOUND:
                $dispatcher->forward(array(
                    'controller' => 'errors',
                    'action' => 'show404'
                ));
                return false;
        }
    }
});

Thoughts?

Thanks!

Of course there is. Your dispatcher must be injected into your DI as a service with the same name. If your $eventsManager is an instance of Phalcon\DI\Injectable:

$this->dispatcher->forward(…); 
$this->di->get('dispatcher')->forward(…);

If not:

DI::getDefault()->get('dispatcher')->forward(…);

Edit:

Yep, that isn't very clear from the docs that there is a shared Events Manager, all examples I saw show only the usage of a freshly created instance. Looking at the code of the Di/FactoryDefault it seems there is a service for that with the same name. You can get it using the same syntax as above.

DI::getDefault()->get('eventsManager')->attach('dispatch', …);

The whole thing should look like this and must be setup somewhere after you configure your DI.

$di->get('eventsManager')->attach("dispatch:beforeException", function($event, $dispatcher, $exception) {
    switch ($exception->getCode()) {
        case Phalcon\Dispatcher::EXCEPTION_HANDLER_NOT_FOUND:
        case Phalcon\Dispatcher::EXCEPTION_ACTION_NOT_FOUND:
            $dispatcher->forward(array(
                'controller' => 'errors',
                'action' => 'show404'
            ));
            return false;
    }
});

$di->get('dispatcher')->setEventsManager($di->get('eventsManager'));
