Binding Zend2 form data from doctrine2 ODM

Question

Is there a better way to bind data from a doctrine2 ODM entity class to a Zend2 form besides using bind()?

If so, what would it be? Would I just retrieve the data as an array and pass each individual field? I am struggling with this and most likely making it harder than it needs to be.

When I call the bind() function it outputs a Zend error referencing the default hydrator. Do I need to do something special in my entity class?

Edit: Here are the exact errors Zend is throwing

~\vendor\zendframework\zendframework\library\Zend\Stdlib\Hydrator\ArraySerializable.php:35

Zend\Stdlib\Hydrator\ArraySerializable::extract expects the provided object to implement getArrayCopy()

They make me think I need to either:

1. use Zends hydrators (which I'd have to research how to implement) or
2. use doctrine2's hydrators (which, I'd also have to figure out the best way to implement)

Answer 1

For Zend\Form being able to hydrating your entity you need to have something like that in your entity class:

public function getArrayCopy()
{
    return get_object_vars($this);
}

Answer 2

in you .../Model/XXXXTable.php
define a function want to get a record.

    $id = (int)$id;
    $row = $this->tableGateway->select(array('id'=>$id));
    $row = $row->current();    //this line is very important

Answer 3

I use the following code at module.config.php to use doctrine hydrator

$form = new ...;
$dm = $sm->get('doctrine.documentmanager.odm_default');
$form->setHydrator(new \DoctrineModule\Stdlib\Hydrator\DoctrineObject($dm));
return $form;

Answer 4

I use the populate method in my entity class. something like this

  public function populate($data = array())
    {
        $this->id = ( isset($data['id'])) ? $data['id'] : null;
        $this->username = (isset($data['username'])) ? $data['username'] : null;
        $this->pass = (isset($data['pass'])) ? $data['pass'] : null;               

    }

and then in controller you can use populate function something like this.

$user = new User();
$request = $this->getRequest();
$user->populate($request->getPost());

I am not sure if I understand your quesiton correctly.
