Doctrine Data Fixtures Extension

, _(*1)

This extension aims to provide a simple way to manage and execute the loading of data fixtures for the Doctrine ORM or ODM. You can write fixture classes by implementing the Doctrine\Common\DataFixtures\FixtureInterface interface:, _(*2)

namespace MyDataFixtures;

use Doctrine\Common\Persistence\ObjectManager;
use Doctrine\Common\DataFixtures\FixtureInterface;

class UserFixtureLoader implements FixtureInterface
{
    public function load(ObjectManager $manager)
    {
        $user = new User();
        $user->setUsername('jwage');
        $user->setPassword('test');

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

Now you can begin adding the fixtures to a loader instance:, _(*3)

use Doctrine\Common\DataFixtures\Loader;
use MyDataFixtures\LoadUserData;

$loader = new Loader();
$loader->addFixture(new LoadUserData());

You can load a set of fixtures from a directory as well:, _(*4)

$loader->loadFromDirectory('/path/to/MyDataFixtures');

Or you can load a set of fixtures from a file:, _(*5)

$loader->loadFromFile('/path/to/MyDataFixtures/MyFixture1.php');

You can get the added fixtures using the getFixtures() method:, _(*6)

$fixtures = $loader->getFixtures();

Now you can easily execute the fixtures:, _(*7)

use Doctrine\Common\DataFixtures\Executor\ORMExecutor;
use Doctrine\Common\DataFixtures\Purger\ORMPurger;

$purger = new ORMPurger();
$executor = new ORMExecutor($em, $purger);
$executor->execute($loader->getFixtures());

If you want to append the fixtures instead of purging before loading then pass true to the 2nd argument of execute:, _(*8)

$executor->execute($loader->getFixtures(), true);

In case if fixture objects have relations to other fixtures, it is now possible to easily add a reference to that object by name and later reference it to form a relation. Here is an example fixtures for Role and User relation, _(*9)

namespace MyDataFixtures;

use Doctrine\Common\DataFixtures\AbstractFixture;
use Doctrine\Common\Persistence\ObjectManager;

class LoadUserRoleData extends AbstractFixture
{
    public function load(ObjectManager $manager)
    {
        $adminRole = new Role();
        $adminRole->setName('admin');

        $anonymousRole = new Role();
        $anonymousRole->setName('anonymous');

        $manager->persist($adminRole);
        $manager->persist($anonymousRole);
        $manager->flush();

        // store reference to admin role for User relation to Role
        $this->addReference('admin-role', $adminRole);
    }
}

And the User data loading fixture:, _(*10)

namespace MyDataFixtures;

use Doctrine\Common\DataFixtures\AbstractFixture;
use Doctrine\Common\Persistence\ObjectManager;

class LoadUserData extends AbstractFixture
{
    public function load(ObjectManager $manager)
    {
        $user = new User();
        $user->setUsername('jwage');
        $user->setPassword('test');
        $user->setRole(
            $this->getReference('admin-role') // load the stored reference
        );

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

        // store reference of admin-user for other Fixtures
        $this->addReference('admin-user', $user);
    }
}

Fixture ordering

Notice that the fixture loading order is important! To handle it manually implement one of the following interfaces:, _(*11)

OrderedFixtureInterface

Set the order manually:, _(*12)

namespace MyDataFixtures;

use Doctrine\Common\DataFixtures\AbstractFixture;
use Doctrine\Common\DataFixtures\OrderedFixtureInterface;
use Doctrine\Common\Persistence\ObjectManager;

class MyFixture extends AbstractFixture implements OrderedFixtureInterface
{
    public function load(ObjectManager $manager)
    {}

    public function getOrder()
    {
        return 10; // number in which order to load fixtures
    }
}

DependentFixtureInterface

Provide an array of fixture class names:, _(*13)

namespace MyDataFixtures;

use Doctrine\Common\DataFixtures\AbstractFixture;
use Doctrine\Common\DataFixtures\DependentFixtureInterface;
use Doctrine\Common\Persistence\ObjectManager;

class MyFixture extends AbstractFixture implements DependentFixtureInterface
{
    public function load(ObjectManager $manager)
    {}

    public function getDependencies()
    {
        return array('MyDataFixtures\MyOtherFixture'); // fixture classes fixture is dependent on
    }
}

class MyOtherFixture extends AbstractFixture
{
    public function load(ObjectManager $manager)
    {}
}

Notice the ordering is relevant to Loader class., _(*14)
