Answer 1

You are mixing up two different approaches of retrieving data from your database.
You can either use the Zend approach as in TableGateway's or you can go with Doctrine (EntityManager/Repositories).
So you've got to make a choice between one of the methods you want to use within your controller.
So if you want to stick with Doctrine, you could take a look at the following slides of Ocramius: http://ocramius.github.io/presentations/doctrine-orm-and-zend-framework-2/#/59
So you pretty much have to update your User model:
namespace User\Model;
use Doctrine\ORM\Mapping AS ORM;
/**
* #ORM\Entity()
*/
class User
{
/**
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
* #ORM\Column(type="integer")
*/
public $id;
/** #ORM\Column(type="string") */
public $fullname;
public function exchangeArray(array $data){
$this->id = (!empty($data['id'])) ? $data['id']: null;
$this->title = (!empty($data['fullname'])) ? $data['fullname']: null;
}
public function getArrayCopy(){
return[
'id'=>$this->id,
'fullname'=>$this->fullname,
];
}
}
Update the following file module.config.php of your User module and add the following to your configuration:
array(
'doctrine' => array(
'driver' => array(
'application_entities' => array(
'class' =>'Doctrine\ORM\Mapping\Driver\AnnotationDriver',
'cache' => 'array',
'paths' => array(__DIR__ . '/../src/User/Model')
),
'orm_default' => array(
'drivers' => array(
'User\model' => 'application_entities'
)
),
)
),
Notice that this requires the Doctrine-ORM-module. See: https://github.com/doctrine/DoctrineORMModule
