Doctrine2 ORM OneToMany or ManyToOne not working - doctrine-orm

Question

I would like to have the relationship between 2 tables, with OneToMany and ManyToOne relationships.
Survey
id
title
Questions:
id
survey_id
So i am looking to list the surveys and their respective questions, so how can i achieve that.
Here is my code,
Survey Entity:
<?php
namespace Survey\Entity;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;
use Library\Entity\BaseEntity;
/**
* Description of Survey
*
* #author Mubarak
*/
/**
* #ORM\Entity
* #ORM\Table(name="surveys")
*/
class Survey extends BaseEntity{
public function __construct() {
$this->questions = new ArrayCollection();
}
/**
* #ORM\Column(name="title", type="string")
* #var string
*/
protected $title;
/**
* #ORM\Column(name="description", type="string")
* #var string
*/
protected $description;
/**
* #ORM\OneToMany(targetEntity="Survey\Entity\Questions", mappedBy="surveys")
*/
private $questions;
public function getTitle() {
return $this->title;
}
public function setTitle($title) {
$this->title = $title;
}
public function getDescription() {
return $this->description;
}
public function setDescription($description) {
$this->description = $description;
return $this;
}
public function getQuestions() {
return $this->questions;
}
public function setQuestions(ArrayCollection $questions) {
$this->questions = $questions;
}
public function __toString() {
return __CLASS__ . ": [id: {$this->id}, name: {$this->name}]";
}
}
Below is the Questions Entity:
<?php
namespace Survey\Entity;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;
use Library\Entity\BaseEntity;
/**
* Description of Survey Questions
*
* #author Mubarak
*/
/**
* #ORM\Entity
* #ORM\Table(name="survey_questions")
*/
class Questions extends BaseEntity{
/**
* #ORM\Column(name="question", type="string")
* #var string
*/
protected $question;
/**
* #ORM\ManyToOne(targetEntity="Survey\Entity\Survey", inversedBy="questions")
* #ORM\JoinColumn(name="survey_id", referencedColumnName="id")
*/
private $surveys;
public function getQuestion() {
return $this->question;
}
public function setQuestion($question) {
$this->question = $question;
}
public function getSurveys() {
return $this->surveys;
}
public function setSurveys(ArrayCollection $surveys) {
$this->surveys = $surveys;
}
public function __toString() {
return __CLASS__ . ": [id: {$this->id}, name: {$this->name}]";
}
}
What is the mistake i am doing here, this is my code to get the surveys and questions:
$surveysInterface = $this->surveyService->getAllSurveys();
foreach($surveysInterface as $survey){
$surveysArray[] = array(
'id' => $survey->getId(),
'title' => $survey->getTitle(),
'description' => $survey->getDescription(),
'isActive' => $survey->getActive(),
'questions' => array(
'question' => $survey->getQuestions()->getQuestion()
)
);
}

Answer 1

'questions' => array(
'question' => $survey->getQuestions()->getQuestion()
)
This part look wrong since getQuestions() function return array of Questions entities. Suggest to change it to
'questions' => $survey->getQuestions()
