Doctrine 2 ORM - Search in oneToMany relation (QueryBuilder) - php

Question

I'm trying resolve following problem.
I have OrderEntity and in OrderEntity is relation ship to OrderStatusHistory (OneToMany).
/**
* #ORM\OneToMany(targetEntity="OrderStatusHistory", mappedBy="order")
*/
protected $statuses;
OrderStatusHistory entity:
class OrderStatusHistory extends BaseEntity
{
/**
* #ORM\ManyToOne(targetEntity="Order",cascade={"persist"})
* #ORM\JoinColumn(name="order_id", referencedColumnName="id")
**/
protected $order;
/**
* #ORM\ManyToOne(targetEntity="OrderStatus",cascade={"persist"})
* #ORM\JoinColumn(name="status_id", referencedColumnName="id")
**/
protected $status;
/**
* #ORM\Column(type="datetime")
*/
protected $time;
public function __construct()
{
$this->time = new \DateTime('now');
}
}
And now i need select order where was last status with ID 4. I'm tried many variants with QB, but any of them does not work.

There's several ways, you can join to that table and use WITH, or you can use WHERE, or you can just use the ID. Here's some examples:
Using DQL:
$dql = "SELECT o
FROM Order o
WHERE o.orderStatus = 4"
or
$dql = "SELECT o
FROM Order o
INNER JOIN o.orderStatus orderStatus
WITH orderStatus.id = 4"
OR:
$dql = "SELECT o
FROM Order o
INNER JOIN o.orderStatus orderStatus
WHERE orderStatus.id = 4"
Or Query Builder:
$queryBuilder->select('o')
->from('Order', 'o')
->where('o.orderStatus = 4');
