Neo4j Data Fixtures Extension
=============================

[](#neo4j-data-fixtures-extension)

This extension aims to provide a simple way to manage and execute the loading of data fixtures for the Neo4j OGM. You can write fixture classes by implementing the Expio\\Common\\Neo4jDataFixtures\\FixtureInterface interface:

```
namespace MyDataFixtures;

use Kwattro\Neo4j\GraphManager;
use Expio\Common\Neo4jDataFixtures\FixtureInterface;

class LoadUserData implements FixtureInterface
{
    public function load(GraphManager $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 Expio\Common\Neo4jDataFixtures\Loader;
use MyDataFixtures\LoadUserData;

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

```

You can load a set of fixtures from a directory as well:

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

```

You can get the added fixtures using the getFixtures() method:

```
$fixtures = $loader->getFixtures();

```

Now you can easily execute the fixtures:

```
use Expio\Common\Neo4jDataFixtures\Executor\OGMExecutor;
use Expio\Common\Neo4jDataFixtures\Purger\OGMPurger;

$purger = new OGMPurger();
$executor = new OGMExecutor($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
--------------------------------

[](#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 Expio\Common\Neo4jDataFixtures\AbstractFixture;
use HireVoice\Neo4j\EntityManager;

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:

```
namespace MyDataFixtures;

use Expio\Common\Neo4jDataFixtures\AbstractFixture;
use HireVoice\Neo4j\EntityManager;

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
----------------

[](#fixture-ordering)

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

### OrderedFixtureInterface

[](#orderedfixtureinterface)

Set the order manually:

```
namespace MyDataFixtures;

use Expio\Common\Neo4jDataFixtures\AbstractFixture;
use Expio\Common\Neo4jDataFixtures\OrderedFixtureInterface;
use HireVoice\Neo4j\EntityManager;

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

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

```

### DependentFixtureInterface

[](#dependentfixtureinterface)

Provide an array of fixture class names:

```
namespace MyDataFixtures;

use Expio\Common\Neo4jDataFixtures\AbstractFixture;
use Expio\Common\Neo4jDataFixtures\DependentFixtureInterface;
use HireVoice\Neo4j\EntityManager;

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:
------------------

[](#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: **git submodule init**
- run: **git submodule update**
- copy the phpunit config **cp phpunit.xml.dist phpunit.xml**
- run: **phpunit**
