Doctrine 2 get items from related entities - orm

Question

I have an entity with ManyToOne, OneToOne relations. I have another entity, which is linked to the first one and what I want to do is to get information about the first entity as well as all other entities, which are related to it.
For some reason when I make the call, it returns NULL in the related entity.
Code:
<?php
namespace App\Model\Entities;
use Doctrine\ORM\Mapping as ORM,
Doctrine\Common\Collections\ArrayCollection;
use Kdyby\Doctrine\Entities\BaseEntity;
/**
* Doctrine entity for resorts in destinations
* #package App\Model\Entities
* #ORM\Entity
*/
class Resort extends BaseEntity
{
/**
* autoincremented resort id
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue
*/
protected $id;
/**
* resort name
* #ORM\Column(type="string")
*/
protected $title;
/**
* #ORM\OneToOne(targetEntity="ResortProperties", mappedBy="resort", cascade={"persist"})
*/
private $properties;
public function __construct()
{
$this->properties = new ArrayCollection();
}
/**
* HERE I WANT TO GET DATA FROM ANOTHER ENTITY
* #return type
*/
public function getProperties()
{
return $this->properties;
}
}
And the related entity is this:
<?php
namespace App\Model\Entities;
use Doctrine\ORM\Mapping as ORM,
Doctrine\Common\Collections\ArrayCollection;
use Kdyby\Doctrine\Entities\BaseEntity;
/**
* Doctrine entity for resort properties
* #package App\Model\Entities
* #ORM\Entity
*/
class ResortProperties extends BaseEntity
{
/**
* autoincremented id
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue
*/
protected $id;
/**
* resort id
* #ORM\OneToOne(targetEntity="Resort", inversedBy="Resort", cascade={"persist", "remove"})
* #ORM\JoinColumn(onDelete="CASCADE")
*/
protected $resort;
/**
* parameter1
* #ORM\Column(type="string")
*/
protected $parameter1;
}
I expected, that when I call $repository->findAll(); I would get all Resort entities and in Resort->properties would be joined ResortProperty entity, but it is NULL.
I don't know what I did wrong, can someone point out my mistake? Thanks

Answer 1

I assume the problem is the JoinColumn-Annotation.
The Entity with the Foreign-key (ResortProperties) needs to know, how to join the two tables.
The "inversedBy"-Statement on the Resort-Entity then uses this rule.
It should look something like the following in your ResortProperties-Entity:
/**
* resort id
* #ORM\OneToOne(targetEntity="Resort", inversedBy="Resort", cascade={"persist", "remove"})
* #ORM\JoinColumn(name="resort_id", referencedColumnName="id")
*/
protected $resort;
"resort_id" is the name of your foreign-key-column.
Hope this helps.

Answer 2

In ResortProperties entity I had to make this change:
class ResortProperties extends BaseEntity
{
/**
* resort id
* #ORM\OneToOne(targetEntity="Resort", inversedBy="properties", cascade={"persist", "remove"})
* #ORM\JoinColumn(name="resort_id", referencedColumnName="id", onDelete="CASCADE")
*/
protected $resort;
}
And in Resort entity I had to change it like this:
class Resort extends BaseEntity
{
/**
* #ORM\OneToOne(targetEntity="ResortProperties", mappedBy="resort", cascade={"persist"})
*/
private $properties;
public function __construct()
{
parent::__construct();
$this->properties = new ArrayCollection();
}
}
Now it's working properly, hope this will help others
