This PHP >=7.0
library is a collection of traits and interfaces
that add behaviors to Doctrine2 entities and repositories.
It currently handles:
- blameable
- filterable
- geocodable
- joinable
- loggable
- sluggable
- softDeletable
- sortable
- timestampable
- translatable
- tree
We realize we don't have so much time anymore to maintain this project as it should be maintained. Therefore we are looking for maintainers. Open an issue if you want to keep working on this.
Some behaviors (translatable, timestampable, softDeletable, blameable, geocodable) need Doctrine subscribers in order to work. Make sure to activate them by reading the Subscribers section.
composer require knplabs/doctrine-behaviors:~1.1
By default, when integrated with Symfony, all subscribers are enabled (if you don't specify any configuration for the bundle). But you can enable behaviors you need in a whitelist manner:
knp_doctrine_behaviors:
blameable: false
geocodable: ~ # Here null is converted to false
loggable: ~
sluggable: true
soft_deletable: true
# All others behaviors are disabled
If you use symfony2, you can easily register them in:
- Recommended way:
Add to AppKernel
class AppKernel
{
function registerBundles()
{
$bundles = array(
//...
new Knp\DoctrineBehaviors\Bundle\DoctrineBehaviorsBundle(),
//...
);
//...
return $bundles;
}
}
- Deprecated way: Importing a service definition file:
# app/config/config.yml
imports:
- { resource: ../../vendor/knplabs/doctrine-behaviors/config/orm-services.yml }
You can also register them using doctrine2 api:
<?php
$em->getEventManager()->addEventSubscriber(new \Knp\DoctrineBehaviors\ORM\Translatable\TranslatableSubscriber);
// register more if needed
All you have to do is to define a Doctrine2 entity and use traits:
<?php
use Doctrine\ORM\Mapping as ORM;
use Knp\DoctrineBehaviors\Model as ORMBehaviors;
/**
* @ORM\Entity(repositoryClass="CategoryRepository")
*/
class Category implements ORMBehaviors\Tree\NodeInterface, \ArrayAccess
{
use ORMBehaviors\Blameable\Blameable,
ORMBehaviors\Geocodable\Geocodable,
ORMBehaviors\Loggable\Loggable,
ORMBehaviors\Sluggable\Sluggable,
ORMBehaviors\SoftDeletable\SoftDeletable,
ORMBehaviors\Sortable\Sortable,
ORMBehaviors\Timestampable\Timestampable,
ORMBehaviors\Translatable\Translatable,
ORMBehaviors\Tree\Node
;
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="NONE")
*/
protected $id;
}
For some behaviors like tree, you can use repository traits:
<?php
use Doctrine\ORM\EntityRepository;
use Knp\DoctrineBehaviors\ORM as ORMBehaviors;
class CategoryRepository extends EntityRepository
{
use ORMBehaviors\Tree\Tree,
}
Voila!
You now have a working Category
that behaves like:
<?php
$category = new Category;
$category->setId(1); // tree nodes need an id to construct path.
$child = new Category;
$child->setId(2);
$child->setChildNodeOf($category);
$em->persist($child);
$em->persist($category);
$em->flush();
$root = $em->getRepository('Category')->getTree();
$root->getParentNode(); // null
$root->getChildNodes(); // ArrayCollection
$root[0][1]; // node or null
$root->isLeafNode(); // boolean
$root->isRootNode(); // boolean
it is possible to use another identifier than
id
, simply overridegetNodeId
and return your custom identifier (works great in combination withSluggable
)
If you're working on a Category
entity, the Translatable
behavior expects a CategoryTranslation entity in the
same folder of Category entity by default.
The default naming convention (or its customization via trait methods) avoids you to manually handle entity associations. It is handled automatically by the TranslationSubscriber.
In order to use the Translatable trait, you will have to create this CategoryTranslation
entity.
<?php
use Doctrine\ORM\Mapping as ORM;
use Knp\DoctrineBehaviors\Model as ORMBehaviors;
/**
* @ORM\Entity
*/
class CategoryTranslation
{
use ORMBehaviors\Translatable\Translation;
/**
* @ORM\Column(type="string", length=255)
*/
protected $name;
/**
* @ORM\Column(type="string", length=255)
*/
protected $description;
/**
* @return string
*/
public function getName()
{
return $this->name;
}
/**
* @param string
* @return null
*/
public function setName($name)
{
$this->name = $name;
}
/**
* @return string
*/
public function getDescription()
{
return $this->description;
}
/**
* @param string
* @return null
*/
public function setDescription($description)
{
$this->description = $description;
}
}
The corresponding Category entity needs to use ORMBehaviors\Translatable\Translatable;
and should only contain fields that you do not need to translate.
<?php
use Doctrine\ORM\Mapping as ORM;
use Knp\DoctrineBehaviors\Model as ORMBehaviors;
/**
* @ORM\Entity
*/
class Category
{
use ORMBehaviors\Translatable\Translatable;
/**
* @ORM\Column(type="string", length=255)
*/
protected $someFieldYouDoNotNeedToTranslate;
}
After updating the database, ie. with ./console doctrine:schema:update --force
,
you can now work on translations using translate
or getTranslations
methods.
<?php
$category = new Category;
$category->translate('fr')->setName('Chaussures');
$category->translate('en')->setName('Shoes');
$em->persist($category);
// In order to persist new translations, call mergeNewTranslations method, before flush
$category->mergeNewTranslations();
$category->translate('en')->getName();
In case you prefer to use a different class name for the translation entity, or want to use a separate namespace, you have 2 ways :
If you want to define a custom translation entity class name globally :
Override the trait Translatable
and his method getTranslationEntityClass
and the trait Translation
and his method getTranslatableEntityClass
in the translation entity.
If you override one, you also need to override the other to return the inverse class.
Example: Let's say you want to create a sub namespace AppBundle\Entity\Translation to stock translations classes then put overrided traits in that folder.
<?php
namespace AppBundle\Entity\Translation;
use Knp\DoctrineBehaviors\Model\Translatable\Translatable;
use Symfony\Component\PropertyAccess\PropertyAccess;
trait TranslatableTrait
{
use Translatable;
/**
* @inheritdoc
*/
public static function getTranslationEntityClass()
{
$explodedNamespace = explode('\\', __CLASS__);
$entityClass = array_pop($explodedNamespace);
return '\\'.implode('\\', $explodedNamespace).'\\Translation\\'.$entityClass.'Translation';
}
}
<?php
namespace AppBundle\Entity\Translation;
use Knp\DoctrineBehaviors\Model\Translatable\Translation;
trait TranslationTrait
{
use Translation;
/**
* @inheritdoc
*/
public static function getTranslatableEntityClass()
{
$explodedNamespace = explode('\\', __CLASS__);
$entityClass = array_pop($explodedNamespace);
// Remove Translation namespace
array_pop($explodedNamespace);
return '\\'.implode('\\', $explodedNamespace).'\\'.substr($entityClass, 0, -11);
}
}
If you use that way make sure you override trait parameters of DoctrineBehaviors :
parameters:
knp.doctrine_behaviors.translatable_subscriber.translatable_trait: AppBundle\Entity\Translation\TranslatableTrait
knp.doctrine_behaviors.translatable_subscriber.translation_trait: AppBundle\Entity\Translation\TranslationTrait
If you want to define a custom translation entity class name just for a single translatable class :
Override the trait method getTranslationEntityClass
in the translatable entity and getTranslatableEntityClass
in the translation entity. If you override one, you also need to override the other to return the inverse class.
You can configure the way the subscriber guesses the current locale, by giving a callable as its first argument.
This library provides a callable object (Knp\DoctrineBehaviors\ORM\Translatable\CurrentLocaleCallable
) that returns the current locale using Symfony2.
An extra feature allows you to proxy translated fields of a translatable entity.
You can use it in the magic __call
method of you translatable entity
so that when you try to call getName
(for example) it will return you the translated value of the name for current locale:
<?php
public function __call($method, $arguments)
{
return $this->proxyCurrentLocaleTranslation($method, $arguments);
}
// or do it with PropertyAccessor that ships with Symfony SE
// if your methods don't take any required arguments
public function __call($method, $arguments)
{
return \Symfony\Component\PropertyAccess\PropertyAccess::createPropertyAccessor()->getValue($this->translate(), $method);
}
<?php
$category = new Category;
$em->persist($category);
$em->flush();
// get id
$id = $category->getId();
// now remove it
$em->remove($category);
$em->flush();
// hey, I'm still here:
$category = $em->getRepository('Category')->findOneById($id);
// but I'm "deleted"
$category->isDeleted(); // === true
// restore me
$category->restore();
//look ma, I am back
$category->isDeleted(); // === false
//do not forget to call flush method to apply the change
$em->flush();
<?php
$category = new Category;
$em->persist($category);
$em->flush();
// I'll delete you tomorrow
$category->setDeletedAt((new \DateTime())->modify('+1 day'));
// OK, I'm here
$category->isDeleted(); // === false
/*
* 24 hours later...
*/
// OK, I'm deleted
$category->isDeleted(); // === true
<?php
$category = new Category;
$em->persist($category);
$em->flush();
$id = $category->getId();
$category = $em->getRepository('Category')->findOneById($id);
$category->getCreatedAt();
$category->getUpdatedAt();
If you wish to change the doctrine type of the database fields that will be created for timestampable models you can set the following parameter like so:
parameters:
knp.doctrine_behaviors.timestampable_subscriber.db_field_type: datetimetz
datetimetz
here is a useful one to use if you are working with a Postgres database, otherwise you may encounter some
timezone issues. For more information on this see:
http://doctrine-dbal.readthedocs.org/en/latest/reference/known-vendor-issues.html#datetime-datetimetz-and-time-types
The default type is datetime
.
Blameable is able to track creators and updators of a given entity. A blameable callable is used to get the current user from your application.
In the case you are using a Doctrine Entity to represent your users, you can configure the subscriber to manage automatically the association between this user entity and your entites.
Using symfony2, all you have to do is to configure the DI parameter named %knp.doctrine_behaviors.blameable_subscriber.user_entity%
with a fully qualified namespace,
for example:
# app/config/config.yml
parameters:
knp.doctrine_behaviors.blameable_subscriber.user_entity: AppBundle\Entity\User
Then, you can use it like that:
<?php
$category = new Category;
$em->persist($category);
// instances of %knp.doctrine_behaviors.blameable_subscriber.user_entity%
$creator = $category->getCreatedBy();
$updater = $category->getUpdatedBy();
Loggable is able to track lifecycle modifications and log them using any third party log system. A loggable callable is used to get the logger from anywhere you want.
<?php
/**
* @ORM\Entity
*/
class Category
{
use ORMBehaviors\Loggable\Loggable;
// you can override the default log messages defined in trait:
public function getUpdateLogMessage(array $changeSets = [])
{
return 'Changed: '.print_r($changeSets, true);
}
public function getRemoveLogMessage()
{
return 'removed!';
}
}
These messages are then passed to the configured callable. You can define your own, by passing another callable to the LoggableSubscriber:
<?php
$em->getEventManager()->addEventSubscriber(
new \Knp\DoctrineBehaviors\ORM\Loggable\LoggableSubscriber(
new ClassAnalyzer,
function($message) {
// do stuff with message
}
)
);
If you're using symfony, you can also configure which callable to use:
// app/config/config.yml
parameters:
knp.doctrine_behaviors.loggable_subscriber.logger_callable.class: Your\InvokableClass
Geocodable Provides extensions to PostgreSQL platform in order to work with cube and earthdistance extensions.
It allows you to query entities based on geographical coordinates. It also provides an easy entry point to use 3rd party libraries like the excellent geocoder to transform addresses into latitude and longitude.
<?php
$geocoder = new \Geocoder\Geocoder;
// register geocoder providers
// $subscriber instanceof GeocodableSubscriber (add "knp.doctrine_behaviors.geocodable_subscriber" into your services.yml)
$subscriber->setGeolocationCallable(function($entity) use($geocoder) {
$location = $geocoder->geocode($entity->getAddress());
return new Point(
$location->getLatitude(),
$location->getLongitude()
));
});
$category = new Category;
$em->persist($category);
$location = $category->getLocation(); // instanceof Point
// find cities in a circle of 500 km around point 47 lon., 7 lat.
$nearCities = $repository->findByDistance(new Point(47, 7), 500);
Sluggable generates slugs (uniqueness is not guaranteed) for an entity.
Will automatically generate on update/persist (you can disable the on update generation by overriding getRegenerateSlugOnUpdate
to return false.
You can also override the slug delimiter from the default hyphen by overriding getSlugDelimiter
.
Slug generation algo can be changed by overriding generateSlugValue
.
Use cases include SEO (i.e. URLs like http://example.com/post/3/introduction-to-php)
<?php
use Doctrine\ORM\Mapping as ORM;
use Knp\DoctrineBehaviors\Model as ORMBehaviors;
/**
* @ORM\Entity
*/
class BlogPost
{
use ORMBehaviors\Sluggable\Sluggable;
/**
* @ORM\Column(type="string")
*/
protected $title;
public function getSluggableFields()
{
return [ 'title' ];
}
public function generateSlugValue($values)
{
return implode('-', $values);
}
}
Filterable can be used at the Repository level
It allows to simple filter our result
Joined filters example:
<?php
use Doctrine\ORM\Mapping as ORM;
/**
* @ORM\Entity(repositoryClass="ProductRepository")
*/
class ProductEntity
{
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @ORM\Column(type="string", nullable=true)
*/
private $name;
/**
* @ORM\Column(type="integer")
*/
private $code;
/**
* @ORM\OneToMany(targetEntity="Order", mappedBy="product")
*/
protected $orders;
}
and repository:
<?php
use Knp\DoctrineBehaviors\ORM\Filterable;
use Doctrine\ORM\EntityRepository;
class ProductRepository extends EntityRepository
{
use Filterable\FilterableRepository;
public function getLikeFilterColumns()
{
return ['e:name', 'o:code'];
}
public function getEqualFilterColumns()
{
return [];
}
protected function createFilterQueryBuilder()
{
return $this
->createQueryBuilder('e')
->leftJoin('e.orders', 'o');
}
}
Now we can filtering using:
$products = $em->getRepository('Product')->filterBy(['o:code' => '21']);
Callables are used by some subscribers like blameable and geocodable to fill information based on 3rd party system.
For example, the blameable callable can be any symfony2 service that implements __invoke
method or any anonymous function, as soon as they return currently logged in user representation (which means everything, a User entity, a string, a username, ...).
For an example of DI service that is invoked, look at the Knp\DoctrineBehaviors\ORM\Blameable\UserCallable
class.
In the case of geocodable, you can set it as any service that implements __invoke
or anonymous function that returns a Knp\DoctrineBehaviors\ORM\Geocodable\Type\Point
object.
