DoctrineFixturesBundle

Installation

If you're using Symfony Flex, run this command and you're done:

1

$ composer require --dev orm-fixtures

If you're not using Flex, run this other command instead:

1

$ composer require --dev doctrine/doctrine-fixtures-bundle

Writing Fixtures

Data fixtures are PHP classes where you create objects and persist them to the database.

Imagine that you want to add some Product objects to your database. No problem! Create a fixtures class and start adding products:

// src/DataFixtures/AppFixtures.php
namespace App\DataFixtures;

use App\Entity\Product;
use Doctrine\Bundle\FixturesBundle\Fixture;
use Doctrine\Persistence\ObjectManager;

class AppFixtures extends Fixture
{
    public function load(ObjectManager $manager): void
    {
        // create 20 products! Bam!
        for ($i = 0; $i < 20; $i++) {
            $product = new Product();
            $product->setName('product '.$i);
            $product->setPrice(mt_rand(10, 100));
            $manager->persist($product);
        }

        $manager->flush();
    }
}

Loading Fixtures

Once your fixtures have been written, load them by executing this command:

1
2

# when using the ORM
$ php bin/console doctrine:fixtures:load

This command looks for all services tagged with doctrine.fixture.orm. If you're using the default service configuration, any class that implements ORMFixtureInterface (for example, those extending from Fixture) will automatically be registered with this tag.

To see other options for the command, run:

1

$ php bin/console doctrine:fixtures:load --help

Accessing Services from the Fixtures

In some cases you may need to access your application's services inside a fixtures class. No problem! Your fixtures class is a service, so you can use normal dependency injection:

class AppFixtures extends Fixture
{
    private UserPasswordHasherInterface $hasher;

    public function __construct(UserPasswordHasherInterface $hasher)
    {
        $this->hasher = $hasher;
    }

    // ...
    public function load(ObjectManager $manager): void
    {
        $user = new User();
        $user->setUsername('admin');

        $password = $this->hasher->hashPassword($user, 'pass_1234');
        $user->setPassword($password);

        $manager->persist($user);
        $manager->flush();
    }
}

Splitting Fixtures into Separate Files

In most applications, creating all your fixtures in just one class is fine. This class may end up being a bit long, but it's worth it because having one file helps keeping things simple.

If you do decide to split your fixtures into separate files, Symfony helps you solve the two most common issues: sharing objects between fixtures and loading the fixtures in order.

    public function load(ObjectManager $manager): void
    {
        $userAdmin = new User('admin', 'pass_1234');
        $manager->persist($userAdmin);
        $manager->flush();

        // other fixtures can get this object using the UserFixtures::ADMIN_USER_REFERENCE constant
        $this->addReference(self::ADMIN_USER_REFERENCE, $userAdmin);
    }

    public function getDependencies(): array
    {
        return [
            UserFixtures::class,
        ];
    }
}

Fixture Groups: Only Executing Some Fixtures

By default, all of your fixture classes are executed. If you only want to execute some of your fixture classes, you can organize them into groups.

The simplest way to organize a fixture class into a group is to make your fixture implement FixtureGroupInterface:

1
2
3
4
5
6
7
8
9
10
11
12
13
14

// src/DataFixtures/UserFixtures.php

+ use Doctrine\Bundle\FixturesBundle\FixtureGroupInterface;

- class UserFixtures extends Fixture
+ class UserFixtures extends Fixture implements FixtureGroupInterface
{
    // ...

+     public static function getGroups(): array
+     {
+         return ['group1', 'group2'];
+     }
}

To execute all of your fixtures for a given group, pass the --group option:

1
2
3
4

$ php bin/console doctrine:fixtures:load --group=group1

# or to execute multiple groups
$ php bin/console doctrine:fixtures:load --group=group1 --group=group2

Alternatively, instead of implementing the FixtureGroupInterface, you can also tag your service with doctrine.fixture.orm and add an extra group option set to a group your fixture should belong to.

Regardless of groups defined in the fixture or the service definition, the fixture loader always adds the short name of the class as a separate group so you can load a single fixture at a time. In the example above, you can load the fixture using the UserFixtures group:

1

$ php bin/console doctrine:fixtures:load --group=UserFixtures

Specifying purging behavior

By default all previously existing data is purged using DELETE FROM table statements. If you prefer to use TRUNCATE table statements for purging, use --purge-with-truncate.

If you want to exclude a set of tables from being purged, e.g. because your schema comes with pre-populated, semi-static data, pass the option --purge-exclusions. Specify --purge-exclusions multiple times to exclude multiple tables:

1

$ php bin/console doctrine:fixtures:load --purge-exclusions=post_category --purge-exclusions=comment_type

You can also customize purging behavior significantly more and implement a custom purger plus a custom purger factory:

// src/Purger/CustomPurger.php
namespace App\Purger;

use Doctrine\Common\DataFixtures\Purger\PurgerInterface;

// ...
class CustomPurger implements PurgerInterface
{
    public function purge(): void
    {
        // ...
    }
}

// src/Purger/CustomPurgerFactory.php
namespace App\Purger;
// ...
use Doctrine\Bundle\FixturesBundle\Purger\PurgerFactory;

class CustomPurgerFactory implements PurgerFactory
{
    public function createForEntityManager(?string $emName, EntityManagerInterface $em, array $excluded = [], bool $purgeWithTruncate = false) : PurgerInterface
    {
        return new CustomPurger($em);
    }
}

The next step is to register our custom purger factory and specify its alias.

# config/services.yaml
services:
    App\Purger\CustomPurgerFactory:
        tags:
            - { name: 'doctrine.fixtures.purger_factory', alias: 'my_purger' }

use App\Purger\CustomerPurgerFactory;

return function(ContainerConfigurator $configurator): void {
    $services = $configurator->services();

    $services->set(CustomerPurgerFactory::class)
        ->tag('doctrine.fixtures.purger_factory', ['alias' => 'my_purger'])
    ;
};

With the --purger option we can now specify to use my_purger instead of the default purger.

$ php bin/console doctrine:fixtures:load --purger=my_purger

How to load Fixtures from a different Directory

By default, fixtures are loaded from the src/DataFixtures directory. In this example, we are going to load our DataFixtures from a new fixtures directory.

First, add a new PSR-4 autoload-entry in the composer.json with the new fixtures directory:

1
2
3
4
5
6

"autoload-dev": {
    "psr-4": {
        "...": "...",
        "DataFixtures\\": "fixtures/"
    }
},

Then, enable Dependency Injection for the fixtures directory:

1
2
3
4

# config/services.yaml
services:
    DataFixtures\:
        resource: '../fixtures'

// config/services.php
namespace Symfony\Component\DependencyInjection\Loader\Configurator;

return function(ContainerConfigurator $container): void {
    $services = $container->services()
        ->defaults()
            ->autowire()
            ->autoconfigure();

    $services->load('DataFixtures\\', '../fixtures');
};
