Symfony3 I have to show from a related entity - php

Question

I have a question.
I have 2 entity
/**
* #ORM\Entity
* #ORM\Table(name="call_center")
*/
class Call {
/**
* #ORM\GeneratedValue(strategy="AUTO")
* #ORM\Id
* #ORM\Column(type="integer")
*/
private $id;
/**
* #ORM\OneToMany(targetEntity="Number", mappedBy="number")
* #ORM\Column(type="string")
*/
private $number;
/**
* #ORM\Column(type="string")
*/
private $value;
......
getters setters
/**
* #ORM\Entity
* #ORM\Table(name="number")
*/
class Number {
/**
* #ORM\GeneratedValue(strategy="AUTO")
* #ORM\Id
* #ORM\Column(type="integer")
*
*/
private $id;
/**
* #ORM\ManyToOne(targetEntity="Call", inversedBy="number")
* #ORM\JoinColumn(nullable=false)
*/
private $number;
/**
* #ORM\Column(type="string")
*/
private $link;
And I would like to show my data in controller.
This is my controller
class DefaultController extends Controller
{
/**
* #Route("/pl/", name="homepage")
*/
public function indexAction(Request $request)
{
$em = $this->getDoctrine()->getRepository('AppBundle:Call')->findAll();
foreach ($em as $name) {
switch(1) {
case $name->getNumber():
echo $name->getValue();
echo $name->getLink(); <----PROBLEME
break;
default:
break;
}
}
return $this->render('default/index.html.twig', array(
'em' => $name
));
}
}
Data with entity call displayed but I don't know how dipsplay data from Number (getLink()). The problem is that I have a loop in which I have to display for a particular value relationship. Probably I have to create repository for entity?
Entity Call
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set number
*
* #param string $number
*
* #return Call
*/
public function setNumber($number)
{
$this->number = $number;
return $this;
}
/**
* Get number
*
* #return string
*/
public function getNumber()
{
return $this->number;
}
/**
* Set value
*
* #param string $value
*
* #return Call
*/
public function setValue($value)
{
$this->value = $value;
return $this;
}
/**
* Get value
*
* #return string
*/
public function getValue()
{
return $this->value;
}
entity Number
/**
* Set number
*
* #param \AppBundle\Entity\Call $number
*
* #return Number
*/
public function setNumber(\AppBundle\Entity\Call $number)
{
$this->number = $number;
return $this;
}
/**
* Get number
*
* #return \AppBundle\Entity\Call
*/
public function getNumber()
{
return $this->number;
}
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set link
*
* #param string $link
*
* #return Number
*/
public function setLink($link)
{
$this->link = $link;
return $this;
}
/**
* Get link
*
* #return string
*/
public function getLink()
{
return $this->link;
}

Answer 1

Maybe you have a string because you tell doctrine to put a string ?
remove the following annotation from your relation :
#ORM\Column(type="string")

Answer 2

Have you tried to access it via $name->getNumber()->getLink() ?
as pointed out below, by tny, you should fix your annotations, or the above will not work, as getNumber() is currently returning a string instead of a Number instance
