Doctrine JSON ODM library

Latest Stable Version Total Downloads License Build Status Code Coverage Scrutinizer Code Quality

Inspired by https://github.com/dunglas/doctrine-json-odm

This is beta version of library. Main differences from Dunglas library:

  • library does not store any metadata in json field;
  • doctrine ODM type uses main Symfony serializer service (so you can easily extend serialization process by adding normalizers/denormalizers globally in dependency injection config);
  • automatic registration of ODM types for Doctrine (using Symfony autowiring and autoconfigure features).

Features

  • Object-Document Mapping with database json types
  • Doctrine 2.5+ support
  • PostgreSQL 9.4+ support
  • Symfony 4+ support (not tested with Symfony 2 and 3)
  • MySQL support not tested

Additional features

  • Automatic registering normalizers for use with Java-like collections from ramsey/collection library

Install

Install with Symfony 4

To install the library, use Composer.

composer require goodwix/doctrine-json-odm

Add lines to config/bundles.php (no automatic configuration is available for beta version).

<?php

return [
    // ...
    Goodwix\DoctrineJsonOdm\Bridge\Symfony\DoctrineJsonOdmBundle::class => ['all' => true],
];

Create package config file config/packages/doctrine-json-odm.yaml with next content.

doctrine_json_odm:
  mapping:
    paths:
      - '%kernel.project_dir%/src/ODM'

there src/ODM is the root path for your ODM entities (like src/Entity for Doctrine).

Usage

Basic usage with automatic ODM types registration

Create entity class for ODM type in ODM-specific directory (like src/ODM) and mark it with \Goodwix\DoctrineJsonOdm\Annotation\ODM annotation.

namespace App\ODM;

use Goodwix\DoctrineJsonOdm\Annotation\ODM;

/**
 * @ODM()
 */
class Document
{
    /** @var string */
    public $title;

    /** @var string */
    public $description;
}

Create doctrine entity class with field type App\ODM\Document.

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;
use App\ODM\Document;

/**
 * @ORM\Entity()
 */
class DocumentStorage
{
    /**
     * @ORM\Column(type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     *
     * @var int
     */
    public $id;

    /**
     * @ORM\Column(type=Document::class, nullable=true)
     *
     * @var Document
     */
    public $document;
}

Now you can easily manage your ORM entity with ODM class field

$documentStorage = $entityManager->find(DocumentStorage::class, $id);
$documentStorage->document->title = 'ODM document title';
$documentStorage->document->description = 'ODM document description';

Manual usage with Doctrine and Symfony Serializer component

To manually register Doctrine ODM types use ODMType::registerODMType() method.

require_once __DIR__.'/../vendor/autoload.php';

use Goodwix\DoctrineJsonOdm\Type\ODMType;
use Symfony\Component\Serializer\SerializerInterface;

class Document { }

ODMType::registerODMType(
    Document::class,
    new class implements SerializerInterface
    {
        public function serialize($data, $format, array $context = [])  { /* Implement serialize() method. */ }
        public function deserialize($data, $type, $format, array $context = [])  { /* Implement deserialize() method. */ }
    }
);

Examples with Symfony application

You can see example of Symfony 4 application with using ODM library in this directory.

You can’t perform that action at this time.
