在这里，我尝试使用 ResultSetMapping 来映射 nativeQuery 生成的结果。但我不知道为什么学说总是抛出未定义的索引错误。谁能帮我解决这个问题？这是我的代码： PlaceMarkerRepository：
namespace Leo\FoodRadarBundle\Entity;
use Doctrine\ORM\EntityRepository;
use Doctrine\ORM\Query\ResultSetMappingBuilder;
/**
* PlaceMarkerRepository
*
* This class was generated by the Doctrine ORM. Add your own custom
* repository methods below.
*/
class PlaceMarkerRepository extends EntityRepository
{
public function findNearBy($query,$lat, $lng, $radius){
$rsm = new ResultSetMappingBuilder($this->getEntityManager());
// $rsm = new ResultSetMappingBuilder();
// $rsm->addRootEntityFromClassMetadata('LeoFoodRadarBundle:PlaceMarker', 'p');
// $rsm->addJoinedEntityFromClassMetadata('LeoFoodRadarBundle:Coordinate', 'c', 'p', 'coordinate', array('id' => 'coordinate_id'));
$rsm->addEntityResult('LeoFoodRadarBundle:PlaceMarker', 'p');
$rsm->addFieldResult('p', 'id', 'id');
$rsm->addFieldResult('p', 'name', 'name');
$rsm->addJoinedEntityResult('LeoFoodRadarBundle:Coordinate' , 'c', 'p', 'coordinate');
$rsm->addFieldResult('c', 'coordinate_id', 'id');
$rsm->addFieldResult('c', 'latitude', 'latitude');
$rsm->addFieldResult('c', 'longitude', 'longitude');
$sql ="SELECT p.id, p.name, c.latitude, c.longitude, c.id as coordinate_id
FROM placeMarker p join coordinate c on p.coordinate_id = c.id
";
$this->getEntityManager()->createNativeQuery($sql, $rsm)->getResult();
}
}
和地标：
namespace Leo\FoodRadarBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Leo\FoodRadarBundle\Entity\PlaceMarker
*
* @ORM\Table(name="placeMarker")
* @ORM\Entity(repositoryClass="Leo\FoodRadarBundle\Entity\PlaceMarkerRepository")
*/
class PlaceMarker {
/**
* @var integer $id
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @var Coordinate coordinate
* @ORM\OneToOne(targetEntity="Coordinate")
* @ORM\JoinColumn(name="coordinate_id", referencedColumnName="id")
*/
private $coordinate;
/**
*
* @var Address address
* @ORM\OneToOne(targetEntity="Address")
* @ORM\JoinColumn(name="address_id", referencedColumnName="id")
*/
private $address;
/**
*
* @ORM\Column(name="name", type="string", length=100)
*/
private $name;
/**
* Get id
*
* @return integer
*/
public function getId() {
return $this->id;
}
/**
* Set coordinate
*
* @param Leo\FoodRadarBundle\Entity\Coordinate $coordinate
* @return PlaceMarker
*/
public function setCoordinate(\Leo\FoodRadarBundle\Entity\Coordinate $coordinate = null) {
$this->coordinate = $coordinate;
return $this;
}
/**
* Get coordinate
*
* @return Leo\FoodRadarBundle\Entity\Coordinate
*/
public function getCoordinate() {
return $this->coordinate;
}
/**
* Set address
*
* @param Leo\FoodRadarBundle\Entity\Address $address
* @return PlaceMarker
*/
public function setAddress(\Leo\FoodRadarBundle\Entity\Address $address = null) {
$this->address = $address;
return $this;
}
/**
* Get address
*
* @return Leo\FoodRadarBundle\Entity\Address
*/
public function getAddress() {
return $this->address;
}
/**
* Set name
*
* @param string $name
* @return PlaceMarker
*/
public function setName($name)
{
$this->name = $name;
return $this;
}
/**
* Get name
*
* @return string
*/
public function getName()
{
return $this->name;
}
}
坐标：
<?php
namespace Leo\FoodRadarBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Leo\FoodRadarBundle\Entity\Coordinate
*
* @ORM\Table(name="coordinate")
* @ORM\Entity
*/
class Coordinate
{
/**
* @var integer $id
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @ORM\Column(type="float")
*/
private $longitude;
/**
* @ORM\Column(type="float")
*/
private $latitude;
/**
* Get id
*
* @return integer
*/
public function getId()
{
return $this->id;
}
/**
* Get longitude
* @return float
*/
public function getLongitude() {
return $this->longitude;
}
/**
* Set longitude
*/
public function setLongitude($longitude) {
$this->longitude = $longitude;
}
/**
* Get Latitude
* @return float
*/
public function getLatitude() {
return $this->latitude;
}
/**
* Set Latitude
*/
public function setLatitude($latitude) {
$this->latitude = $latitude;
}
}
此语句引起的错误：
$targetClass = $this->_ce[$relation['targetEntity']];
有关错误的信息是：
