Different behaviour with slightly similar entity - php

Question

I made a web application with Symfony2. There are 2 kind of user, a UserOperator and a UserGroundStation. Both of them extend User.
USER GROUND STATION
namespace Acme\ManagementBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use PUGX\MultiUserBundle\Validator\Constraints\UniqueEntity;
use Symfony\Component\Validator\Constraints as Assert;
/**
* #ORM\Entity
* #ORM\HasLifecycleCallbacks()
* #ORM\Table(name="user_GroundStation")
* #UniqueEntity(fields = "username", targetClass = "Acme\ManagementBundle\Entity\User",
message="Username already_used")
* #UniqueEntity(fields = "email", targetClass = "Acme\ManagementBundle\Entity\User",
message="Email already_used")
*/
class UserGroundStation extends User
{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #ORM\Column(type="string", length=60)
* #var String
*/
protected $name;
/**
* #var float
*
* #ORM\Column(name="latitude", type="float")
*/
private $latitude;
/**
* #var float
*
* #ORM\Column(name="longitude", type="float")
*/
private $longitude;
/**
* Set latitude
*
* #param string $latitude
* #return UserGroundStation
*/
public function setLatitude($latitude)
{
$this->latitude = $latitude;
return $this;
}
/**
* Get latitude
*
* #return string
*/
public function getLatitude()
{
return $this->latitude;
}
/**
* Set longitude
*
* #param float $longitude
* #return UserGroundStation
*/
public function setLongitude($longitude)
{
$this->longitude = $longitude;
return $this;
}
/**
* Get longitude
*
* #return float
*/
public function getLongitude()
{
return $this->longitude;
}
/**
* #ORM\PrePersist
*/
public function setCreatedAtValue()
{
$this->addRole('ROLE_GS');
}
}
USER OPERATOR
namespace Acme\ManagementBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use PUGX\MultiUserBundle\Validator\Constraints\UniqueEntity;
use Symfony\Component\Validator\Constraints as Assert;
/**
* #ORM\Entity
* #ORM\HasLifecycleCallbacks()
* #ORM\Table(name="user_Operator")
* #UniqueEntity(fields = "username", targetClass = "Acme\ManagementBundle\Entity\User",
message="Username already_used")
* #UniqueEntity(fields = "email", targetClass = "Acme\ManagementBundle\Entity\User",
message="Email already_used")
*/
class UserOperator extends User
{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #ORM\Column(type="string", length=60)
* #var String
*/
protected $name;
/**
* #ORM\PrePersist
*/
public function setCreatedAtValue()
{
$this->addRole('ROLE_OPERATOR');
}
}
They extend User.
When I call the registration page for UserOperator, it works, when I call registration page for UserGroundStation, Symfony alerts me:
Neither the property "mission" nor one of the methods "getMission()", "isMission()", "hasMission()", "__get()" exist and have public access in class "Acme\ManagementBundle\Entity\UserGroundStation".
How is it possible? Where can I find the error?
USER
namespace Acme\ManagementBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use FOS\UserBundle\Model\User as BaseUser;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
/**
* #ORM\Entity
* #ORM\Table(name="user")
* #ORM\InheritanceType("JOINED")
* #ORM\DiscriminatorColumn(name="type", type="string")
* #ORM\DiscriminatorMap({"user_one" = "UserGroundStation", "user_two" = "UserOperator"})
* #ORM\MappedSuperclass()
*
*/
abstract class User extends BaseUser
{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #ORM\ManyToMany(targetEntity="Acme\ManagementBundle\Entity\Mission", mappedBy="users")
*/
protected $missions;
public function __construct(){
$this -> missions = new ArrayCollection();
}
public function setMissions(Collection $missions){
$this -> missions = $missions;
return $this;
}
public function addMission($mission){
$this -> missions -> add($mission);
return $this;
}
public function getMissions(){
return $this -> missions;
}

Answer 1

It was really a dummy problem.
They have different FormType:
RegistrationUserOperatorFormType is different to RegistrationUserGroundStationFormType and
ProfileUserGroundStationFormType is different to ProfileUserOperatorFormType.
