TRACKING POLICIES
D E F E R R E D I M P L I C I T
With this policy, Doctrine detects the changes by a property-by-property comparison at commit time and
also detects changes to entities or new entities that are referenced by other managed entities …
http://doctrine-orm.readthedocs.org/en/latest/reference/change-tracking-policies.html
D E F E R R E D I M P L I C I T
http://doctrine-orm.readthedocs.org/en/latest/reference/change-tracking-policies.html
class User { /** * @ORM\Id * @ORM\Column(name="ID", type="string", length=37, nullable=false) */ private $id; /** * @ORM\Column(name="FIRST_NAME", type="string", length=100, nullable=false) */ private $firstName;
/** * @ORM\Column(name="LAST_NAME", type="string", length=100, nullable=false) */ private $lastName;
/** * @ORM\Column(name="BIRTH_DATE", type="date", nullable=false) */ private $birthDate; }
UOW
$em->flush();
D E F E R R E D E X P L I C I T
… the difference is that Doctrine 2 only considers entities that have been explicitly marked for change
detection through a call to EntityManager::persist(entity)
or through a save cascade.
http://doctrine-orm.readthedocs.org/en/latest/reference/change-tracking-policies.html
D E F E R R E D E X P L I C I T
http://doctrine-orm.readthedocs.org/en/latest/reference/change-tracking-policies.html
class User { /** * @ORM\Id * @ORM\Column(name="ID", type="string", length=37, nullable=false) */ private $id; /** * @ORM\Column(name="FIRST_NAME", type="string", length=100, nullable=false) */ private $firstName;
/** * @ORM\Column(name="LAST_NAME", type="string", length=100, nullable=false) */ private $lastName;
/** * @ORM\Column(name="BIRTH_DATE", type="date", nullable=false) */ private $birthDate; }
UOW
$em->persist($user); $em->flush();
N O T I F Y
This policy is based on the assumption that the entities notify interested listeners of changes to their properties.
For that purpose, a class that wants to use this policy needs to implement the NotifyPropertyChanged
interface
http://doctrine-orm.readthedocs.org/en/latest/reference/change-tracking-policies.html
N O T I F Y
<?php
use Doctrine\Common\NotifyPropertyChanged, Doctrine\Common\PropertyChangedListener;
/** * @Entity * @ChangeTrackingPolicy("NOTIFY") */ class User implements NotifyPropertyChanged { // ... private $_listeners = array();
public function addPropertyChangedListener(PropertyChangedListener $listener) { $this->_listeners[] = $listener; }
}
N O T I F Y
<?php
// . . . protected function _onPropertyChanged($propName, $oldValue, $newValue) { if ($this->_listeners) { foreach ($this->_listeners as $listener) { $listener->propertyChanged($this, $propName, $oldValue, $newValue); } } }
public function setData($data) { if ($data != $this->data) { $this->_onPropertyChanged('data', $this->data, $data); $this->data = $data; } } }
U S E R E A D O N LY E N T I T I E S
This means that the entity marked as read only is never considered for updates
U S E R E A D O N LY E N T I T I E S
/** * @ORM\Entity(readOnly=true) */ class NewsTag { /** * @ORM\Id * @ORM\Column(name="ID", type="string", length=37, nullable=false) */ private $id; }
