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 App\Entity;
use ApiPlatform\Doctrine\Orm\Filter\OrderFilter;
use ApiPlatform\Doctrine\Orm\Filter\SearchFilter;
use ApiPlatform\Metadata\ApiFilter;
use ApiPlatform\Metadata\ApiResource;
use App\Repository\VehicleRepository;
use Doctrine\ORM\Mapping as ORM;
#[ORM\Entity(repositoryClass: VehicleRepository::class)]
#[ORM\InheritanceType('JOINED')]
#[ORM\DiscriminatorColumn(name: 'discr', type: 'string')]
#[ORM\DiscriminatorMap([
'car' => Car::class,
'bike' => Bike::class
])]
#[ApiResource]
#[ApiFilter(OrderFilter::class)]
class Vehicle
{
#[ORM\Id]
#[ORM\GeneratedValue]
#[ORM\Column]
private ?int $id = null;
#[ORM\Column(length: 255)]
#[ApiFilter(SearchFilter::class, strategy: 'partial')]
private ?string $brand = null;
#[ORM\Column]
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;
}
}
<?php
namespace App\Entity;
use ApiPlatform\Doctrine\Orm\Filter\OrderFilter;
use ApiPlatform\Metadata\ApiFilter;
use ApiPlatform\Metadata\ApiResource;
use App\Repository\BikeRepository;
use Doctrine\ORM\Mapping as ORM;
#[ORM\Entity(repositoryClass: BikeRepository::class)]
#[ApiResource]
#[ApiFilter(OrderFilter::class)]
class Bike extends Vehicle
{
#[ORM\Column]
private ?bool $hasCarrier = null;
public function hasCarrier(): ?bool
{
return $this->hasCarrier;
}
public function setHasCarrier(bool $hasCarrier): static
{
$this->hasCarrier = $hasCarrier;
return $this;
}
}
<?php
namespace App\Entity;
use ApiPlatform\Doctrine\Orm\Filter\OrderFilter;
use ApiPlatform\Metadata\ApiFilter;
use ApiPlatform\Metadata\ApiResource;
use App\Repository\CarRepository;
use Doctrine\ORM\Mapping as ORM;
#[ORM\Entity(repositoryClass: CarRepository::class)]
#[ApiResource]
#[ApiFilter(OrderFilter::class)]
class Car extends Vehicle
{
#[ORM\Column]
private ?int $numberOfDoors = null;
public function getNumberOfDoors(): ?int
{
return $this->numberOfDoors;
}
public function setNumberOfDoors(int $numberOfDoors): static
{
$this->numberOfDoors = $numberOfDoors;
return $this;
}
}
Tout ce fait avec
#[ORM\InheritanceType('JOINED')]
#[ORM\DiscriminatorColumn(name: 'discr', type: 'string')]
#[ORM\DiscriminatorMap([
'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
