Symfony without Flex

This library ships with a Symfony bundle FidryAliceDataFixturesBundle.

Doctrine ORM

To use it with Doctrine do not forget to install doctrine/doctrine-bundle and enable the DoctrineBundle (done by default in Symfony Standard Edition).

Then, enable the bundle by updating your app/AppKernel.php file to enable the bundle:

<?php
// app/AppKernel.php

public function registerBundles()
{
    $bundles = [
        new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
        // ...
        new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
    ];

    if (in_array($this->getEnvironment(), ['dev', 'test'])) {
        //...
        $bundles[] = new Nelmio\Alice\Bridge\Symfony\NelmioAliceBundle();
        $bundles[] = new Fidry\AliceDataFixtures\Bridge\Symfony\FidryAliceDataFixturesBundle();
    }

    return $bundles;
}

Doctrine ODM

To use it with Doctrine do not forget to install doctrine/mongodb-odm and enable the DoctrineMongoDBBundle.

Then, enable the bundle by updating your app/AppKernel.php file to enable the bundle:

<?php
// app/AppKernel.php

public function registerBundles()
{
    $bundles = [
        new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
        // ...
        new Doctrine\Bundle\MongoDBBundle\DoctrineMongoDBBundle(),
    ];

    if (in_array($this->getEnvironment(), ['dev', 'test'])) {
        //...
        $bundles[] = new Nelmio\Alice\Bridge\Symfony\NelmioAliceBundle();
        $bundles[] = new Fidry\AliceDataFixtures\Bridge\Symfony\FidryAliceDataFixturesBundle();
    }

    return $bundles;
}

Doctrine PHPCR

To use it with Doctrine do not forget to install doctrine/doctrine-bundle and enable the DoctrineBundle (done by default in Symfony Standard Edition) and DoctrinePHPCRBundle (from doctrine/phpcr-odm)

Then, enable the bundle by updating your app/AppKernel.php file to enable the bundle:

<?php
// app/AppKernel.php

public function registerBundles()
{
    $bundles = [
        new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
        // ...
        new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
        new Doctrine\Bundle\PHPCRBundle\DoctrinePHPCRBundle(),
    ];

    if (in_array($this->getEnvironment(), ['dev', 'test'])) {
        //...
        $bundles[] = new Nelmio\Alice\Bridge\Symfony\NelmioAliceBundle();
        $bundles[] = new Fidry\AliceDataFixtures\Bridge\Symfony\FidryAliceDataFixturesBundle();
    }

    return $bundles;
}

Eloquent ORM

To use it with Eloquent do not forget to install illuminate/database and WouterJEloquentBundle (wouterj/eloquent-bundle).

Then, enable the bundle by updating your app/AppKernel.php file to enable the bundle:

<?php
// app/AppKernel.php

public function registerBundles()
{
    $bundles = [
        new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
        // ...
        new WouterJ\EloquentBundle\WouterJEloquentBundle(),
    ];

    if (in_array($this->getEnvironment(), ['dev', 'test'])) {
        //...
        $bundles[] = new Nelmio\Alice\Bridge\Symfony\NelmioAliceBundle();
        $bundles[] = new Fidry\AliceDataFixtures\Bridge\Symfony\FidryAliceDataFixturesBundle();
    }

    //...
    if (in_array($this->getEnvironment(), ['dev', 'test'])) {
        //...
        $bundles[] = new Fidry\AliceDataFixtures\Bridge\Symfony\FidryAliceDataFixturesBundle();
    }

    return $bundles;
}

Configuration

The full configuration reference is:

# app/config/config.yml

# Default config
fidry_alice_data_fixtures:
    default_purge_mode: ~ # default is "delete" but you can change it to "truncate" or "no_purge"
    db_drivers:
        doctrine_orm: ~
        doctrine_mongodb_odm: ~
        doctrine_phpcr_odm: ~
        eloquent_orm: ~

For each driver, is the appropriate bundle is detected, e.g. DoctrineORMBundle for Doctrine and WouterJEloquentBundle for Eloquent, the services related to those driver will be enabled. If you want to skip those checks you can turn a specific driver to true instead. If you want to disable a specific driver, simply force the value false instead.

Basic usage

Create a fixture file in src/AppBundle/Resources/fixtures:

# src/AppBundle/Resources/fixtures/dummy.yml

AppBundle\Entity\Dummy:
    dummy_{1..10}:
        name: <name()>
        related_dummy: '@related_dummy*'
# src/AppBundle/Resources/fixtures/related_dummy.yml

AppBundle\Entity\RelatedDummy:
    related_dummy_{1..10}:
        name: <name()>

Then you can load those files using a LoaderInterface:

<?php

$files = [
    'path/to/src/AppBundle/Resources/fixtures/dummy.yml',
    'path/to/src/AppBundle/Resources/fixtures/related_dummy.yml',
];

// Choose your loader
$loader = $container->get('fidry_alice_data_fixtures.loader.doctrine');         // For Doctrine ORM
$loader = $container->get('fidry_alice_data_fixtures.loader.doctrine_mongodb'); // For Doctrine MongoDB ODM
$loader = $container->get('fidry_alice_data_fixtures.loader.doctrine_phpcr');   // For Doctrine PHPCR
$loader = $container->get('fidry_alice_data_fixtures.loader.eloquent');         // For Eloquent ORM

// Purge the objects, create PHP objects from the fixture files and persist them
$objects = $loader->load($files);

// $objects is now an array of persisted `Dummy` and `RelatedDummy`

Advanced usage

Processors

Processors allow you to process objects before and/or after they are persisted. Processors must implement the Fidry\AliceDataFixtures\ProcessorInterface.

Here is an example where we may use this feature to make sure passwords are properly hashed on a User:

namespace MyApp\DataFixtures\Processor;

use Fidry\AliceDataFixtures\ProcessorInterface;
use MyApp\Hasher\PasswordHashInterface;
use User;

final class UserProcessor implements ProcessorInterface
{
    private $passwordHasher;

    public function __construct(PasswordHashInterface $passwordHasher)
    {
        $this->passwordHasher = $passwordHasher;
    }

    /**
     * @inheritdoc
     */
    public function preProcess(string $fixtureId, $object): void
    {
        if (false === $object instanceof User) {
            return;
        }

        $object->password = $this->passwordHasher->hash($object->password);
    }

    /**
     * @inheritdoc
     */
    public function postProcess(string $fixtureId, $object): void
    {
        // do nothing
    }
}

In Symfony, if you wish to register the processor above you need to tag it with the fidry_alice_data_fixtures.processor tag unless you have autoconfigure enabled:

# app/config/services.yml

services:
    _defaults:
        autoconfigure: true

    AppBundle\DataFixtures\Processor\UserProcessor:
        arguments:
          - '@password_hasher'

Without autoconfigure:

# app/config/services.yml

services:
    AppBundle\DataFixtures\Processor\UserProcessor:
        arguments:
          - '@password_hasher'
        tags: [ { name: fidry_alice_data_fixtures.processor } ]

Exclude tables from purge

You may have some view/read-only tables which should not be truncated when loading the fixtures. To fix that, you can leverage the Purger to exclude them.

The purger for Doctrine is defined here. You see that you can easily create your own purger based on it to retrieve the relevant metadata from the object manager to exclude them:

<?php declare(strict_types=1);

namespace Acme\Alice\Purger;

use Doctrine\Common\DataFixtures\Purger\ORMPurger as DoctrineOrmPurger;
use Doctrine\Common\DataFixtures\Purger\PurgerInterface as DoctrinePurgerInterface;
use Doctrine\Common\Persistence\ObjectManager;
use Fidry\AliceDataFixtures\Persistence\PurgeMode;
use Fidry\AliceDataFixtures\Persistence\PurgerFactoryInterface;
use Fidry\AliceDataFixtures\Persistence\PurgerInterface;
use Nelmio\Alice\IsAServiceTrait;

/**
 * @final
 */
/* final */ class Purger implements PurgerInterface, PurgerFactoryInterface
{
    use IsAServiceTrait;

    private $manager;
    private $purger;

    public function __construct(ObjectManager $manager, PurgeMode $purgeMode = null)
    {
        $this->manager = $manager;
        $this->purger = static::createPurger($manager, $purgeMode);
    }
    // ...

    private static function createPurger(ObjectManager $manager, ?PurgeMode $purgeMode): DoctrinePurgerInterface
    {
        $metaData = $manager->getMetadataFactory()->getAllMetadata();

        $excluded = [];

        foreach ($metaData as $classMetadata) {
            /** @var ClassMetadata $classMetadata */
            if ($classMetadata->isReadOnly) {
                $excluded[] = $classMetadata->getTableName();
            }
        }

        $purger = new DoctrineOrmPurger($manager, $excluded);

        if (null !== $purgeMode) {
            $purger->setPurgeMode($purgeMode->getValue());
        }

        return $purger;
    }
}

In the case of Symfony with Doctrine ORM, you can the override the default purger factory used:

// app/config/services.yaml

services:
    # Override the default service with your own
    fidry_alice_data_fixtures.persistence.purger_factory.doctrine:
        class: Acme\Alice\Purger\Purger
        arguments:
            - '@doctrine.orm.entity_manager'

Usage in tests

It is common to load the fixtures for tests, but then you might need to reset your database between each tests. There is two ways of doing it: purge between each test which works but comes with an overhead and warping the test in a transaction which can be rollbacked at the end of the test. The second approach is usually faster but requires a database that supports transactions and removes the ability to peak at the database in the middle of a test while debugging.

PHPUnit

There are several approaches, the following one is a simple one for test case with Symfony. Depending on your needs, you might use the Symfony base TestCase or a PHPUnit listener. In case of Symfony, take a look at dmaicher/doctrine-test-bundle which transparently provides a transactional run for your tests. In that case you can also disable default purge mode by setting default_purge_mode configuration option to no_purge.

If you are not using Symfony, this should still give you a pretty good idea on how to do it.

With purge:

<?php declare(strict_types=1);

namespace Acme;

use Acme\Entity\Dummy;
use Doctrine\Bundle\DoctrineBundle\Registry;
use Doctrine\Common\DataFixtures\Purger\ORMPurger as DoctrineOrmPurger;
use PHPUnit\Framework\TestCase;

class FooTest extends TestCase
{
    /** @var AppKernel */
    private $kernel;
    /** @var LoaderInterface */
    private $loader;
    /** @var Registry */
    private $doctrine;

    /**
     * @inheritdoc
     */
    public function setUp()
    {
        $this->kernel = new AppKernel('test', true);
        $this->kernel->boot();

        $this->loader = $this->kernel->getContainer()->get('fidry_alice_data_fixtures.loader.doctrine');
        $this->doctrine = $this->kernel->getContainer()->get('doctrine');
    }

    public function tearDown()
    {
        $purger = new DoctrineOrmPurger($this->doctrine->getManager());
        $purger->purge();

        $this->kernel->shutdown();
        $this->kernel = null;
    }

    public function testLoadAFile()
    {
        $this->loader->load([
            '/path/to/my/fixtures/file.yml',
        ]);

        $result = $this->doctrine->getRepository(Dummy::class)->findAll();

        $this->assertEquals(1, count($result));
    }
}

With transaction:

<?php declare(strict_types=1);

namespace Acme;

use Acme\Entity\Dummy;
use Doctrine\Bundle\DoctrineBundle\Registry;
use PHPUnit\Framework\TestCase;

class FooTest extends TestCase
{
    /** @var AppKernel */
    private $kernel;
    /** @var LoaderInterface */
    private $loader;
    /** @var Registry */
    private $doctrine;

    /**
     * @inheritdoc
     */
    public function setUp()
    {
        $this->kernel = new AppKernel('test', true);
        $this->kernel->boot();

        $this->loader = $this->kernel->getContainer()->get('fidry_alice_data_fixtures.loader.doctrine');
        $this->doctrine = $this->kernel->getContainer()->get('doctrine');
        
        $connection = $this->doctrine->getConnection();
        
        // If you are using auto-increment IDs, you might want to reset them. It is usually better to purge/reset
        // things at the beginning of a test so that in case of a failure, you are not ending up in a broken state.
        // With PostgreSQL:
        $connection->executeQuery('ALTER SEQUENCE dummy_sequence RESTART');
        // With MySQL:
        $connection->executeQuery('ALTER TABLE dummy AUTO_INCREMENT = 1');
        
        // Related to the possible failures - see the comment above, you might want to empty some tables here as well.
        // Maybe by using the purger like in the example above? Up to you.
        // It is also a good practice to clear all the repositories. How you collect all of the repositories: leveraging
        // the framework or manually is up to you.
        
        $connection->beginTransaction();
    }

    public function tearDown()
    {
        $this->doctrine->getConnection('default')->rollBack();

        $this->kernel->shutdown();
        $this->kernel = null;
    }

    public function testLoadAFile()
    {
        $this->loader->load([
            '/path/to/my/fixtures/file.yml',
        ]);

        $result = $this->doctrine->getRepository(Dummy::class)->findAll();

        $this->assertEquals(1, count($result));
    }
}

Behat

The idea is pretty much the same as for PHPUnit. You can register a context hooking on the events to start a transaction at the beginning of a scenario and rollback at the end of it:

<?php declare(strict_types=1);

namespace Acme;

use Behat\Behat\Context\Context;
use Doctrine\Bundle\DoctrineBundle\Registry;

class DatabaseContext implements Context
{
    private $doctrine;

    public function __construct(Registry $doctrine)
    {
        $this->doctrine = $doctrine;
    }
    
    /**
     * @BeforeScenario
     */
    public function clearRepositories()
    {
        // Related to the possible failures - see the comment above, you might want to empty some tables here as well.
        // Maybe by using the purger like in the example above? Up to you.
        // It is also a good practice to clear all the repositories. How you collect all of the repositories: leveraging
        // the framework or manually is up to you.
    }

    /**
     * @BeforeScenario
     */
    public function resetSequences()
    {
        $connection = $this->doctrine->getConnection();
                
        // If you are using auto-increment IDs, you might want to reset them. It is usually better to purge/reset
        // things at the beginning of a test so that in case of a failure, you are not ending up in a broken state.
        // With PostgreSQL:
        $connection->executeQuery('ALTER SEQUENCE dummy_sequence RESTART');
        // With MySQL:
        $connection->executeQuery('ALTER TABLE dummy AUTO_INCREMENT = 1');
    }

    /**
     * @BeforeScenario
     */
    public function beginPostgreSqlTransaction()
    {
        $this->doctrine->getConnection()->beginTransaction();
    }

    /**
     * @AfterScenario
     */
    public function rollbackPostgreSqlTransaction()
    {
        $this->doctrine->getConnection()->rollBack();
    }

}
