Question

I started to develop new application, it’s my first application written in ZF2. I have some experience about making application with ZF1 with Doctrine1, but now I would like to do application with using ZF2 and Doctrine2.
Default entities folder is in the module directory. I would like to have one models folder, which is shared in whole application. So I’ve prepared application structure like this:

config
models
 generated
module
 Administration
 Application
public
vendor

I have designed database (MySQL) and imported it to XML form, using Doctrine CLI. I’ve generated also models. But now I have problem – how to use it in my modules? I’ve prepared some code:

protected $em;

public function setEntityManager(EntityManager $em)
{
    $this->em = $em;
}

public function getEntityManager()
{
    if (null === $this->em) {
        $this->em = $this->getServiceLocator()->get('Doctrine\ORM\EntityManager');
    }
    return $this->em;
}

public function indexAction()
{
    return new ViewModel(array(
        'carriers' => $this->getEntityManager()->getRepository('Carrier')->findAll()
    ));
}

And I’ve got an error ‘Class Carrier not found’. It is a problem with paths, but I’m totally newbie in ZF2 and I’ve no idea how to configure it…

Answer 1

You define the path to Doctrine 2’s entities within configuration. Now i assume you have a configuration somewhere similar to this:

'doctrine' => array(
    'driver' => array(
        __NAMESPACE__ . '_driver' => array(
            'class' => 'Doctrine\ORM\Mapping\Driver\AnnotationDriver',
            'cache' => 'array',
            'paths' => array(__DIR__ . '/../src/' . __NAMESPACE__ . '/Entity')
        ),
        'orm_default' => array(
            'drivers' => array(
                __NAMESPACE__ . '\Entity' => __NAMESPACE__ . '_driver'
            )
        )
    )
)

Basically what you have to do is to Map the paths correctly. Within the orm_defaults you can define the driver for each module separately, or just use a global driver.

Within __NAMESPACE__ . '_driver' you define a driver with the given name and also define where exactly the entities get stored. In your case this would probably be something like

'paths' => array(__DIR__ . '/../src/Administration/Entity')

Or whatever your Module is named where your entities are stored. In this case Administration

Additionally, always assign the fully qualified repository name like this:

->getRepository('NAMESPACE\Entity\Carrier')
