Zend FrameWork 2 Get ServiceLocator In Form and populate a drop down list

Question

I need to get the adapter from the form, but still could not.

In my controller I can recover the adapter using the following:

Answer 1

In module.php I create two services. See how I feed the adapter to the form.

public function getServiceConfig()
{
    return array(
        'factories' => array(
            'db_adapter' =>  function($sm) {
                $config = $sm->get('Configuration');
                $dbAdapter = new \Zend\Db\Adapter\Adapter($config['db']);
                return $dbAdapter;
            },

            'my_amazing_form' => function ($sm) {
                return new \dir\Form\SomeForm($sm->get('db_adapter'));
            },

        ),
    );
}

In the form code I use that feed to whatever:

namespace ....\Form;

use Zend\Form\Factory as FormFactory;
use Zend\Form\Form;

class SomeForm extends Form
{

    public function __construct($adapter, $name = null)
    {
        parent::__construct($name);
        $factory = new FormFactory();

        if (null === $name) {
            $this->setName('whatever');
        }

    }
}
