DiscriminatorMap de Doctrine avec Api-platform

  • 61k

Le DiscriminatorMap de Doctrine permet une gestion efficace des entités héritées.
Nous allons prendre l'exemple simple d'une classe Vehicle pour créer deux classes qui vont en hériter : Bike et Car
qui ont des attributs différents mais auront les mêmes que Vehicle.
Avec Api-platform, on pourra faire un GET /vehicles pour avoir tous les vehicules
GET bikes pour tous les bikes et GET /cars 

<?php  namespace AppEntity;  use ApiPlatformDoctrineOrmFilterOrderFilter; use ApiPlatformDoctrineOrmFilterSearchFilter; use ApiPlatformMetadataApiFilter; use ApiPlatformMetadataApiResource; use AppRepositoryVehicleRepository; use DoctrineORMMapping as ORM;  #[ORMEntity(repositoryClass: VehicleRepository::class)] #[ORMInheritanceType('JOINED')] #[ORMDiscriminatorColumn(name: 'discr', type: 'string')] #[ORMDiscriminatorMap([     'car' => Car::class,     'bike' => Bike::class ])] #[ApiResource] #[ApiFilter(OrderFilter::class)] class Vehicle {     #[ORMId]     #[ORMGeneratedValue]     #[ORMColumn]     private ?int $id = null;      #[ORMColumn(length: 255)]     #[ApiFilter(SearchFilter::class, strategy: 'partial')]     private ?string $brand = null;      #[ORMColumn]     private ?DateTimeImmutable $createdAt = null;      public function getId(): ?int     {         return $this->id;     }      public function getBrand(): ?string     {         return $this->brand;     }      public function setBrand(string $brand): static     {         $this->brand = $brand;          return $this;     }      public function getCreatedAt(): ?DateTimeImmutable     {         return $this->createdAt;     }      public function setCreatedAt(DateTimeImmutable $createdAt): static     {         $this->createdAt = $createdAt;          return $this;     } }

Tout ce fait avec 

#[ORMInheritanceType('JOINED')] #[ORMDiscriminatorColumn(name: 'discr', type: 'string')] #[ORMDiscriminatorMap([     'car' => Car::class,     'bike' => Bike::class ])]

InheritanceType peut également être SINGLE_TABLE ce qui signifie que vous n'aurez qu'une seule table pour toutes vos entités

N'oubliez pas également sur les autres classes de rajouter extends Vehicle
