How to declare a EventSubscriber in config.yml using bazinga_geocoder.geocoder service? - google-maps

Question

I am planning to make a reverse geocoding based on the BazingaGeocoderBundle. A simple way to do that is write this simple code in the controller:
$result = $this->container
->get('bazinga_geocoder.geocoder')
->using('google_maps')
->reverse(48.79084170157100,2.42479377175290);
return $this->render("MinnAdsBundle:Motors:test.html.twig",
array('result'=>var_dump($result)));
Until here, things are going well.
My objective is to make the code nicer & resuable. So, I used this article to write my own GeocoderEventSubscriber as describer below:
<?php
namespace Minn\AdsBundle\Doctrine\Event;
use Doctrine\Common\EventSubscriber;
use Doctrine\ORM\Event\PreUpdateEventArgs;
use Doctrine\ORM\Event\LifecycleEventArgs;
//use Geocoder\Provider\ProviderInterface;
use Bazinga\Bundle\GeocoderBundle\Geocoder\LoggableGeocoder;
/**
* Subscribes to Doctrine prePersist and preUpdate to update an
* the address components of a MotorsAds entity
*
* #author majallouli
*/
class MotorsAdsGeocoderEventSubscriber implements EventSubscriber {
protected $geocoder;
public function __construct(LoggableGeocoder $geocoder){
$this->geocoder = $geocoder;
}
/**
* Specifies the list of events to listen
*
* #return array
*/
public function getSubscribedEvents(){
return array(
'prePersist',
'preUpdate',
);
}
/**
* Sets a new MotorsAds's address components if not present
*
* #param LifecycleEventArgs $eventArgs
*/
public function prePersist(LifecycleEventArgs $eventArgs){
$motorsAds = $eventArgs->getEntity();
if($motorsAds instanceof \Minn\AdsBundle\Entity\MotorsAds){
if( !$motorsAds->getCountry()){
$em = $eventArgs->getEntityManager();
$this->geocodeMotorsAds($motorsAds,$em);
}
}
}
/**
* Sets an updating MotorsAds's address components if not present
* or any part of address updated
*
* #param PreUpdateEventArgs $eventArgs
*/
public function preUpdate(PreUpdateEventArgs $eventArgs){
$motorsAds = $eventArgs->getEntity();
if($motorsAds instanceof \Minn\AdsBundle\Entity\MotorsAds){
if( !$motorsAds->getCountry() ){
$em = $eventArgs->getEntityManager();
$this->geocodeMotorsAds($motorsAds,$em);
$uow = $em->getUnitOfWork();
$meta = $em->getClassMetadata(get_class($motorsAds));
$uow->recomputeSingleEntityChangeSet($meta, $motorsAds);
}
}
}
/**
* Geocode and set the MotorsAds's address components
*
* #param type $motorsAds
*/
private function geocodeMotorsAds($motorsAds,$em){
$result = $this->geocode
->using('google_maps')
->reverse($motorsAds->getLat(),$motorsAds->getLng());
$motorsAds->setCountry(
$em->getRepository("MinnAdsBundle:Country")->findCountryCode($result['countryCode']));
}
}
After that, I declared my EventSubscriber as a service:
services:
# ...
geocoder_motorsads.listener:
class: Minn\AdsBundle\Doctrine\Event\MotorsAdsGeocoderEventSubscriber
arguments: [#bazinga_geocoder.geocoder] # almost sure that the error is here!!
tags:
- { name: doctrine.event_subscriber }
Actually, I get this error:
ContextErrorException: Notice: Undefined property: Minn\AdsBundle\Doctrine\Event\MotorsAdsGeocoderEventSubscriber::$geocode in /home/amine/NetBeansProjects/tuto/src/Minn/AdsBundle/Doctrine/Event/MotorsAdsGeocoderEventSubscriber.php line 78
I am almost sure that error is in the declaration of arguments of the EventSubscriber. Is it #bazinga_geocoder.geocoder?
Thank you for your help!

Your property is $this->geocoder but you're calling $this->geocode, you're spelling it wrong.
