Symfony2 - Retrieve Relational Data From Doctrine - php

Question

When I try to get data like this, I got missing data:
$this->em->getRepository("PollBundle:Poll")->findAll();
Here are the results that I got: http://i.imgur.com/f0M54og.png
The system is getting poll's data however nothing to show about frequency as you can see. What's wrong?
PollFrequency Entity is like that as following:
namespace PollBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;
/**
* PollFrequency
*
* #ORM\Table(name="poll_frequency")
* #ORM\Entity
*/
class PollFrequency
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #ORM\OneToMany(targetEntity="Poll", mappedBy="poll_frequency")
*/
private $polls;
/**
* #var string
* #ORM\Column(name="frequency", type="string")
*/
private $frequency;
/**
* #var string
* #ORM\Column(name="description", type="string")
*/
private $description;
public function __construct()
{
$this->polls = new ArrayCollection();
}
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set frequency
*
* #param string $frequency
* #return PollFrequency
*/
public function setFrequency($frequency)
{
$this->frequency = $frequency;
return $this;
}
/**
* Get frequency
*
* #return string
*/
public function getFrequency()
{
return $this->frequency;
}
/**
* Set description
*
* #param string $description
* #return PollFrequency
*/
public function setDescription($description)
{
$this->description = $description;
return $this;
}
/**
* Get description
*
* #return string
*/
public function getDescription()
{
return $this->description;
}
/**
* Add polls
*
* #param \PollBundle\Entity\Poll $polls
* #return PollFrequency
*/
public function addPoll(\PollBundle\Entity\Poll $polls)
{
$this->polls[] = $polls;
return $this;
}
/**
* Remove polls
*
* #param \PollBundle\Entity\Poll $polls
*/
public function removePoll(\PollBundle\Entity\Poll $polls)
{
$this->polls->removeElement($polls);
}
/**
* Get polls
*
* #return \Doctrine\Common\Collections\Collection
*/
public function getPolls()
{
return $this->polls;
}
}
Poll Entity is also here as following:
<?php

* #ORM\Column(name="pageload", nullable=false, type="boolean")
*/
private $pageload;
/**

*/
private $loadafter;

Happy Coding to All !

Answer 1

I solved like that. If you need solution. that's it as following:
/**
* #ORM\ManyToOne(targetEntity="PollFrequency", fetch="EAGER")
* #ORM\JoinColumn(name="frequency_id", referencedColumnName="id")
*/
private $frequency;
And also I removed that part of PollFrequency as following:
/**
* #ORM\OneToMany(targetEntity="Poll", mappedBy="poll_frequency")
*/
private $polls;
and everything that related to $polls.
Happy Coding to All!
