Description
I am trying to index a collection by its entity's column which is also a foreign key (association). It seems to me that it is not possible at the moment.
For example:
/**
* @Entity
*/
class Hotel
{
// $id column and other stuff
/**
* @oneToMany(targetEntity="Booking", mappedBy="hotel", indexBy="room")
* @var Booking[]
*/
private $bookings;
}
/**
* @Entity
*/
class Booking
{
/**
* @var Hotel
*
* @Id
* @ManyToOne(targetEntity="Hotel", inversedBy="bookings")
* @JoinColumns({
* @JoinColumn(name="hotel_id", referencedColumnName="id")
* })
*/
private $hotel;
/**
* @var Room
*
* @Id
* @ManyToOne(targetEntity="Room")
* @JoinColumns({
* @JoinColumn(name="room_id", referencedColumnName="id")
* })
*/
private $room;
}
Only possible workaround I found is to define another (plain) entity's property mapped to the same table column and index by it:
/**
* @Entity
*/
class Hotel
{
// $id column and other stuff
/**
* @oneToMany(targetEntity="Booking", mappedBy="hotel", indexBy="roomId")
* @var Booking[]
*/
private $bookings;
}
/**
* @Entity
*/
class Booking
{
// ...
/**
* @var Room
*
* @Id
* @ManyToOne(targetEntity="Room")
* @JoinColumns({
* @JoinColumn(name="room_id", referencedColumnName="id")
* })
*/
private $room;
/**
* @var integer $roomId
*
* @Column(name="room_id", type="integer", nullable=false)
*/
private $roomId;
}
Wouldn't it be easy to support it?
