Doctrine Data Fixtures Extension
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:
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:
use Doctrine\Common\DataFixtures\Loader;
use MyDataFixtures\UserDataLoader;
$loader = new Loader();
$loader->addFixture(new UserDataLoader());
You can load a set of fixtures from a directory as well:
$loader->loadFromDirectory('/path/to/MyDataFixtures');
Or you can load a set of fixtures from a file:
$loader->loadFromFile('/path/to/MyDataFixtures/MyFixture1.php');
You can get the added fixtures using the getFixtures() method:
$fixtures = $loader->getFixtures();
Now you can easily execute the fixtures:
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:
$executor->execute($loader->getFixtures(), true);
Sharing objects between fixtures
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
namespace MyDataFixtures;
use Doctrine\Common\DataFixtures\AbstractFixture;
use Doctrine\Common\Persistence\ObjectManager;
class UserRoleDataLoader 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:
namespace MyDataFixtures;
use Doctrine\Common\DataFixtures\AbstractFixture;
use Doctrine\Common\Persistence\ObjectManager;
class UserDataLoader 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:
OrderedFixtureInterface
Set the order manually:
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:
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.
Running the tests:
PHPUnit 3.5 or newer together with Mock_Object package is required. To setup and run tests follow these steps:
- go to the root directory of data-fixtures
- run: composer install --dev
- copy the phpunit config cp phpunit.xml.dist phpunit.xml
- run: phpunit
