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
