Doctrine Enums Bundle

Symfony bundle for Doctrine enums extension.

Requirements

Minimum PHP version is 8.1.

Installation

composer require enumeum/doctrine-enums-bundle

Bundle registration

If Symfony did not add bundle into ./config/bundles.php then do it manually.

<?php

return [
    // ...
    Enumeum\DoctrineEnumBundle\DoctrineEnumBundle::class => ['all' => true],
];

Setup

Create doctrine_enum.yaml file under Symfony config folder. For single default connection setup is pretty easy

doctrine_enum:
  types:
    - App\EnumType\StatusType
    - App\EnumType\AnotherStatusType
  paths:
    - dir: '%kernel.project_dir%/src/EnumFolder/One'
      namespace: App\EnumFolder\One
    - dir: '%kernel.project_dir%/src/EnumFolder/Two'
      namespace: App\EnumFolder\Two

For multiple named connections config also supports them. Connections naming should be similar to Doctrine.

doctrine_enum:
  connections:
    first:
      types:
        - App\EnumType\AnotherStatusType
      paths:
        - dir: '%kernel.project_dir%/src/EnumFolder/One'
          namespace: App\EnumFolder\One
    second:
      types:
        - App\EnumType\StatusType
      paths:
        - dir: '%kernel.project_dir%/src/EnumFolder/Two'
          namespace: App\EnumFolder\Two

Types and Entities

Enumeum attribute for PHP enum:

#[Enumeum\DoctrineEnum\Attribute\EnumType(name: 'type_name')] this attribute tells that this enum is database type. By default, it creates type in database with its own cases.

Enum setup

<?php
namespace App\Enums;

use Enumeum\DoctrineEnum\Attribute\EnumType;

#[EnumType(name: 'status_type')]
enum StatusType: string
{
    case STARTED = 'started';
    case PROCESSING = 'processing';
    case FINISHED = 'finished';
}

Entity setup

Please note that the configuration of the entity is no different from the usual one. Doctrine supports "enumType" property and converts it transparently.

<?php
namespace App\Entities;

use Doctrine\DBAL\Types\Types;
use Doctrine\ORM\Mapping as ORM;
use App\Enum\StatusType;

/**
 * @ORM\Entity
 * @ORM\Table(name="entity")
 */
#[ORM\Entity]
#[ORM\Table(name: 'entity')]
class Entity
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     */
    #[ORM\Id]
    #[ORM\Column(type: Types::INTEGER)]
    private int $id;

    /**
     * @ORM\Column(type="string", enumType=StatusType::class, options={"comment":"Comment"})
     */
    #[ORM\Column(type: Types::STRING, enumType: StatusType::class, options: ['comment' => 'Comment'])]
    private StatusType $status;

    public function __construct(
        int $id,
        StatusType $status,
    ) {
        $this->id = $id;
        $this->status = $status;
    }

    public function getId(): int
    {
        return $this->id;
    }

    public function getStatus(): StatusType
    {
        return $this->status;
    }
}

Commands

In order to automate enums management bundle provides some commands.

Diff

Diff command will create migration file using Doctrine Migrations bundle config.

./bin/console enumeum:migrations:diff

List of options is generally similar to Doctrine's doctrine:migrations:diff command, except one additional option. "-U" allows to ignore enums already existing in database, otherwise diff command will try to drop them.

Schema validate

Schema validate command will check whether database enums are in sync with their definitions in application.

./bin/console enumeum:schema:validate

This command has optional "--em" and "--conn" options for those cases when application has different from "default" configuration.
Option "-U" allows to ignore enums already existing in database.

Integration with Doctrine's commands

Bundle also allows to use Enumeum commands with appropriate Doctrine's commands to perform better usability.

enumeum:migrations:diff -> doctrine:migrations:diff
enumeum:schema:validate -> doctrine:schema:validate

This is provided by Doctrine's commands overriding using commands decoration. Every Doctrine's command has additional option "-E" which allows to run Enumeum command before the general. Commands decoration is enabled by default and can be disabled by following configuration:

doctrine_enum:
  doctrine:
    commands_decoration: false
