Doctrine Changes Tracker

This package provides an EntityTracker service for your Doctrine entities. This service allows you to easily track changes made to an entity, i.e.

$entity->name = 'foo';
$tracker->hasChanged($entity); // true
$tracker->hasChanged($entity, 'name'); // true

$changeSet=$tracker->getChangeSet($entity, 'name');
$changeSet->from; // Previous value
$changeSet->to; // New value
$changeSet->hadPreviousValue('foo'); // false
$changeSet->hasNewValue('bar'); // false
$changeSet->hasChangedFor(null, 'foo'); // true
$changeSet->hadPreviousValue(whatever()->except(null)); // false
$changeSet->hasNewValue(oneOf('foo', 'bar')); // true

This package also provides a #[TrackChanges] attributes on properties typed as object - this allows Doctrine to be aware on changes on nested objects (which isn't the case by default, unless you assign a different object).

Usage

Just inject EntityTracker in your services and use the helper methods.

Example:

<?php

namespace App\Services;

use App\Entity\Book;
use BenTools\DoctrineChangeSet\Tracker\EntityTracker;
use Doctrine\ORM\EntityManagerInterface;

use function assert;
use function BenTools\DoctrineChangeSet\Tracker\oneOf;
use function BenTools\DoctrineChangeSet\Tracker\whatever;

final readonly class MyService {
    public function __construct(
        private EntityTracker $tracker,
        private EntityManagerInterface $em,
    ) {}
    
    public function createBook(): void 
    {
        $book = new Book();
        $book->title = 'PHP For Dummiez';
        $book->isbn = '00000000001';
        
        assert(true === $this->tracker->hasChanged($book));
        
        $this->em->persist($book);
        $this->em->flush();
    }
    
    public function updateBook(): void 
    {
        $repository = $this->em->getRepository(Book::class)
        $book = $repository->findOneBy(['isbn' => '00000000001']);
        $book->title = 'PHP For Dummies';
        
        assert(true === $this->tracker->hasChanged($book));
        assert(true === $this->tracker->hasChanged($book, 'title'));
        assert(false === $this->tracker->hasChanged($book, 'isbn'));
        assert(true === $this->tracker->getChangeSet($book, 'title')->hadPreviousValue('PHP For Dummiez'));
        assert(true === $this->tracker->getChangeSet($book, 'title')->hasNewValue('PHP For Dummies'));
        
        // Shorthand for both methods above
        assert(true === $this->tracker->getChangeSet($book, 'title')->hasChangedFor('PHP For Dummiez', 'PHP For Dummies'));
        
        // You can also check for multiple values
        assert(true === $this->tracker->getChangeSet($book, 'title')->hadPreviousValue(oneOf('PHP For Dummies', 'PHP For Dummiez')));
        assert(true === $this->tracker->getChangeSet($book, 'title')->hasNewValue(whatever()->except(null, 'PHP For Dummiez')));
        
        $this->em->flush();
    }  
}

Track object changes

By default, Doctrine doesn't track changes on embedded objects. For example:

namespace App\Entity;

use DateTimeImmutable;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\DBAL\Types\Types;

#[ORM\Entity]
class Book
{
    #[ORM\Id, ORM\Column, ORM\GeneratedValue]
    public int $id;

    #[ORM\Column]
    public string $title;

    #[ORM\Column(type: Types::OBJECT)]
    public object $data;
}

Doing this:

$book = $repository->findOneBy([])
$book->data->foo = 'bar'

$em->flush(); // Will have no effect as soon as no other scalar or array property has been changed

To enforce Doctrine track changes on embedded objects, simply add the TrackChanges attribute.

namespace App\Entity;

use BenTools\DoctrineChangeSet\Tracker\TrackChanges;
// ...

#[ORM\Entity]
class Book
{
    // ...

    #[ORM\Column(type: Types::OBJECT)]
    #[TrackChanges]
    public object $data;
}

Installation

composer require bentools/doctrine-changeset

Then, add the following line to your bundles.php:

# config/bundles.php

return [
    // ...
    BenTools\DoctrineChangeSet\Bundle\DoctrineChangeSetBundle::class => ['all' => true],
];

Tests

composer ci:check
