23. PHP Mapping¶
Doctrine ORM also allows you to provide the ORM metadata in the form
of plain PHP code using the ClassMetadata
API. You can write
the code in PHP files or inside of a static function named
loadMetadata($class)
on the entity class itself.
23.1. PHP Files¶
Note
PHPDriver is deprecated and will be removed in 3.0, use StaticPHPDriver instead.
If you wish to write your mapping information inside PHP files that
are named after the entity and included to populate the metadata
for an entity you can do so by using the PHPDriver
:
<?php
$driver = new PHPDriver('/path/to/php/mapping/files');
$em->getConfiguration()->setMetadataDriverImpl($driver);
Now imagine we had an entity named Entities\User
and we wanted
to write a mapping file for it using the above configured
PHPDriver
instance:
<?php
namespace Entities;
class User
{
private $id;
private $username;
}
To write the mapping information you just need to create a file
named Entities.User.php
inside of the
/path/to/php/mapping/files
folder:
<?php
// /path/to/php/mapping/files/Entities.User.php
$metadata->mapField(array(
'id' => true,
'fieldName' => 'id',
'type' => 'integer'
));
$metadata->mapField(array(
'fieldName' => 'username',
'type' => 'string',
'options' => array(
'fixed' => true,
'comment' => "User's login name"
)
));
$metadata->mapField(array(
'fieldName' => 'login_count',
'type' => 'integer',
'nullable' => false,
'options' => array(
'unsigned' => true,
'default' => 0
)
));
Now we can easily retrieve the populated ClassMetadata
instance
where the PHPDriver
includes the file and the
ClassMetadataFactory
caches it for later retrieval:
<?php
$class = $em->getClassMetadata('Entities\User');
// or
$class = $em->getMetadataFactory()->getMetadataFor('Entities\User');
23.2. Static Function¶
In addition to the PHP files you can also specify your mapping
information inside of a static function defined on the entity class
itself. This is useful for cases where you want to keep your entity
and mapping information together but don’t want to use attributes or
annotations. For this you just need to use the StaticPHPDriver
:
<?php
use Doctrine\Persistence\Mapping\Driver\StaticPHPDriver;
$driver = new StaticPHPDriver('/path/to/entities');
$em->getConfiguration()->setMetadataDriverImpl($driver);
Now you just need to define a static function named
loadMetadata($metadata)
on your entity:
<?php
namespace Entities;
use Doctrine\ORM\Mapping\ClassMetadata;
class User
{
// ...
public static function loadMetadata(ClassMetadata $metadata)
{
$metadata->mapField(array(
'id' => true,
'fieldName' => 'id',
'type' => 'integer'
));
$metadata->mapField(array(
'fieldName' => 'username',
'type' => 'string'
));
}
}
23.3. ClassMetadataBuilder¶
To ease the use of the ClassMetadata API (which is very raw) there is a ClassMetadataBuilder
that you can use.
<?php
namespace Entities;
use Doctrine\ORM\Mapping\ClassMetadata;
use Doctrine\ORM\Mapping\Builder\ClassMetadataBuilder;
class User
{
// ...
public static function loadMetadata(ClassMetadata $metadata)
{
$builder = new ClassMetadataBuilder($metadata);
$builder->createField('id', 'integer')->isPrimaryKey()->generatedValue()->build();
$builder->addField('username', 'string');
}
}
The API of the ClassMetadataBuilder has the following methods with a fluent interface:
addField($name, $type, array $mapping)
addField($name, $type, array $mapping)setMappedSuperclass()
setMappedSuperclass()setReadOnly()
setReadOnly()setCustomRepositoryClass($className)
setCustomRepositoryClass($className)setTable($name)
setTable($name)addIndex(array $columns, $indexName)
addIndex(配列 $columns, $indexName)addUniqueConstraint(array $columns, $constraintName)
addUniqueConstraint(配列 $columns, $constraintName)addNamedQuery($name, $dqlQuery)
addNamedQuery($name, $dqlQuery)setJoinedTableInheritance()
setJoinedTableInheritance()setSingleTableInheritance()
setSingleTableInheritance()setDiscriminatorColumn($name, $type = 'string', $length = 255, $columnDefinition = null, $enumType = null)
setDiscriminatorColumn($name, $type = 'string', $length = 255, $columnDefinition = null, $enumType = null)addDiscriminatorMapClass($name, $class)
addDiscriminatorMapClass($name, $class)setChangeTrackingPolicyDeferredExplicit()
setChangeTrackingPolicyDeferredExplicit()setChangeTrackingPolicyNotify()
setChangeTrackingPolicyNotify()addLifecycleEvent($methodName, $event)
addLifecycleEvent($メソッド名, $イベント)addManyToOne($name, $targetEntity, $inversedBy = null)
addManyToOne($name, $targetEntity, $inversedBy = null)addInverseOneToOne($name, $targetEntity, $mappedBy)
addInverseOneToOne($name, $targetEntity, $mappedBy)addOwningOneToOne($name, $targetEntity, $inversedBy = null)
addOwningOneToOne($name, $targetEntity, $inversedBy = null)addOwningManyToMany($name, $targetEntity, $inversedBy = null)
addOwningManyToMany($name, $targetEntity, $inversedBy = null)addInverseManyToMany($name, $targetEntity, $mappedBy)
addInverseManyToMany($name, $targetEntity, $mappedBy)addOneToMany($name, $targetEntity, $mappedBy)
addOneToMany($name, $targetEntity, $mappedBy)
It also has several methods that create builders (which are necessary for advanced mappings):
createField($name, $type)
returns aFieldBuilder
instancecreateField($name, $type) は FieldBuilder インスタンスを返しますcreateManyToOne($name, $targetEntity)
returns anAssociationBuilder
instancecreateManyToOne($name, $targetEntity) は AssociationBuilder インスタンスを返しますcreateOneToOne($name, $targetEntity)
returns anAssociationBuilder
instancecreateOneToOne($name, $targetEntity) は AssociationBuilder インスタンスを返しますcreateManyToMany($name, $targetEntity)
returns anManyToManyAssociationBuilder
instancecreateManyToMany($name, $targetEntity) は ManyToManyAssociationBuilder インスタンスを返しますcreateOneToMany($name, $targetEntity)
returns anOneToManyAssociationBuilder
instancecreateOneToMany($name, $targetEntity) は OneToManyAssociationBuilder インスタンスを返します
