Accessing the service inside the event subscriber
I have an event subscriber with Doctrine events. Inside this, I am trying to call the service that I have registered. I've already called this from the controller and it works there, but when I try to call it in my subscriber, I get the error:
Attempted to call method "get" on class "Path\To\My\Class".
Did you mean to call "getSubscribedEvents"?
The code looks like this:
$embedcode_service = $this->get('myproject.mynamespace.myfield.update');
$embedcode_service->refreshMyField($document);
Why can't I access my service inside this event? How can I access it?

Kerad already answered that I'm just going to clarify:
Add your service to your subscriber:
services:
...
my.subscriber:
class: Acme\SearchBundle\EventListener\SearchIndexerSubscriber
# Service you want to inject
arguments: [ @service_i_want_to_inject.custom ]
tags:
- { name: doctrine.event_subscriber, connection: default }
...
In the php code for your subscriber, assign the injected service to a class variable so that you can access it later:
...
class SearchIndexerSubscriber implements EventSubscriber {
private $myservice;
public function __construct($myservice) {
$this->myservice = $myservice;
}
...
Accessing service methods through a class variable from any method in the subscriber:
$this->myservice->refreshMyField($document);
