zf2 doctrine 2 - Output OnetoOne Unidirectional - doctrine-orm

Question

After annotating an OneToOne Unidirectional, i want to output the joined column, without using a form.
One People Entity has got a column to store the id of Country Entity.
What i can do: I can store the id of the country into the People Entity using a form with a dropdown select, which is bound to the Country Entity.
Problem: I can not enter the value country of the, hopefully correct, joined table.
People Entity:
<?php
namespace People\Entity;
use Doctrine\ORM\Mapping as ORM;
// ...
/**
* A people entity.
*
* #ORM\Entity
* #ORM\Table(name="icd_people")
* #property int $id
// ...
* #property string $ic_hq_country
*/
class People implements InputFilterAwareInterface
{
protected $inputFilter;
/**
* #ORM\Id
* #ORM\Column(type="integer");
*/
protected $id;
/**
* #ORM\Column(type="integer")
* #ORM\OneToOne(targetEntity="Country")
* #ORM\JoinColumn(name="ic_hq_country", referencedColumnName="id")
*/
protected $ic_hq_country;
// getter and setter
}
The Country Entity:
<?php
namespace People\Entity;
use Doctrine\ORM\Mapping as ORM;
//...
/**
* A Country entity.
*
* #ORM\Entity
* #ORM\Table(name="pre_country")
* #property int $id
* #property string $country
*/
class Country implements InputFilterAwareInterface
{
protected $inputFilter;
/**
* #ORM\Id
* #ORM\Column(type="integer");
*/
protected $id;
/**
* #ORM\Column(type="string")
*/
protected $country;
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set country
*
* #param string $country
* #return Country
*/
public function setCountry($country)
{
$this->country = $country;
return $this;
}
/**
* Get country
*
* #return string
*/
public function getCountry()
{
return $this->country;
}
/**
* Convert the object to an array.
*
* #return array
*/
public function getArrayCopy()
{
return get_object_vars($this);
}
public function setInputFilter(InputFilterInterface $inputFilter)
{
throw new \Exception("Not used");
}
public function getInputFilter()
{
throw new \Exception("Not used");
}
}
The Controller Action:
public function indexAction()
{
$userid = $this->zfcUserAuthentication()->getIdentity()->getId();
return new ViewModel(array(
'pea' => $this->getEntityManager()->find('People\Entity\People', $userid),
));
}
The View giving the id of the country, but not the name:
<?php echo $this->escapeHtml($pea->ic_hq_country);?>
I actually expected something like this being possible, to output the country name and not the id:
<?php echo $this->escapeHtml($pea->country);?>
Thank you for reading, and for any help, which could lead me into the right direction!

Answer 1

You should not use the #Column anotation in the $ic_hq_country field of the Peopleentity.
/**
* #ORM\OneToOne(targetEntity="Country")
* #ORM\JoinColumn(name="ic_hq_country", referencedColumnName="id")
*/
protected $ic_hq_country;
like this, hopefully ic_hq_country will be a proxy to the entity instead of the id.
so in your view you can use:
<?php echo $pea->ic_hq_country->getId();?>
and also
<?php echo $this->escapeHtml($pea->ic_hq_country->getCountry());?>
