ZFCUser Identity within another entity - doctrine-orm

Question

Is there a way where you can get the ZfcUser Identity or user_id in another entity?
I've been watching the following link, dealing with the servicemanager.
https://github.com/ZF-Commons/ZfcUser/wiki/How-to-check-if-the-user-is-logged-in#service-manager
When using the service manager, I get the following:
Call to a member function get() on a non-object
at the following line:
$auth = $sm->get('zfcuser_auth_service');
Using ServiceManager
public class CustomEntity implements ServiceManagerAwareInterface
{
protected $sm;
/**
* #ORM\Column(type="integer", nullable=false)
*/
protected $creator_id;
/**
*
* #ORM\Column(type="datetime", nullable=false)
*/
protected $creation_date;
/**
* #ORM\Column(type="integer", nullable=true)
*/
protected $last_modifier_id;
/**
* #ORM\Column(type="datetime", nullable=true)
*/
protected $last_modified_date;
public function setServiceManager(ServiceManager $serviceManager)
{
$this->sm = $serviceManager;
return $this->sm;
}
public function getLoggedUserId()
{
$auth = $this->getServiceManager()->get('zfcuser_auth_service');
return $auth->getIdenty()->getId();
}
/**
* #ORM\PrePersist
*/
public function onPrePersist()
{
//$this->creator_id = $this->getLoggedUserId();
$this->creation_date = new \DateTime('now');
}
/**
* #ORM\PreUpdate
*/
public function onUpdate()
{
//$this->last_modifier_id = $this->getLoggedUserId();
$this->last_modified_date = new \DateTime('now');
}
In the above code I've been trying to use the ServiceManager but without any luck. As I said, its going wrong at this point:
Call to a member function get() on a non-object
at the following line:
$auth = $this->getServiceManager()->get('zfcuser_auth_service');
Aswell as the ServiceManager Interfaces don't have a Get Method, to retreive a ServiceManager. So in that case I also tried to use the ServiceLocator instead of the Manager, but also without any luck.
Old version
I've been able to set the User_id with the controller by creating a set method within the entity.
Controller:
public function addAction()
{
...
$customEntity->setCreator($this->zfcUserAuthentication()->getIdentity()->getId());
$this->getEntityManager()->persist($customEntity);
$this->getEntityManager()->flush();
...
}
Entity:
public function setCreator($user_id){
$this->creator_id = $user_id;
$this->creation_date = new \DateTime;
}
public function setModifier($user_id){
$this->last_modifier_id = $user_id;
$this->last_modified_date = new \DateTime;
}
New version
Instead of setting setCreator or setModifier everytime you are executing an action, it would have been lovely to get the User Identity at the Doctrine Persist or Update.
I would like to have the zfcUser_id inside my Entity. Some code example to show you what I ment:
/**
* #ORM\Entity
* #ORM\HasLifecycleCallbacks
*/
class CustomEntity
{
/**
* #ORM\Column(type="integer", nullable=false)
*/
protected $creator_id;
/**
*
* #ORM\Column(type="datetime", nullable=false)
*/
protected $creation_date;
...
/**
* #ORM\PrePersist
*/
public function onPrePersist()
{
$this->creator_id = ZfcUser_id
$this->creation_date = new \DateTime('now');
}
/**
* #ORM\PreUpdate
*/
public function onUpdate()
{
$this->last_modifier_id = ZfcUser_id
$this->last_modified_date = new \DateTime('now');
}
As you can see, I would like to have the ZfcUser_id at the following functions: onPrePersist and onUpdate to save the creator or updater of this entity/object. And for this version I was looking for a way to get the ZfcUser Identity, and found this link:
https://github.com/ZF-Commons/ZfcUser/wiki/How-to-check-if-the-user-is-logged-in#service-manager
Result based on replies
Create your Entity, create some Set Methods for your fields/attributes. Let your Controller handle this part. For the date(Time) as an default value is being set, you can use onPrePresist, onUpdate or you should check out other Doctrine Block Annotations.
