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:

This is the way I used get around that issue.

firstly, In Module.php, create the service (just as you have done):

// module/Users/Module.php  
public function getServiceConfig()
{
    return array(
            'factories' => array(
                    'Users\Model\UsersTable' =>  function($sm) {
                        $dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
                        $uTable     = new UsersTable($dbAdapter);
                        return $uTable;
                    },
                    //I need to get this to the list of groups
                    'Users\Model\GroupsTable' =>  function($sm) {
                        $dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
                        $gTable     = new GroupsTable($dbAdapter);
                        return $gTable;
                    },
            ),
    );
}

Then in the controller, I got a reference to the Service:

$users = $this->getServiceLocator()->get('Test\Model\TestGroupTable')->fetchAll();
        $options = array();
        foreach ($users as $user)
           $options[$user->id] = $user->name;
        //get the form element
        $form->get('user_id')->setValueOptions($options);

And viola, that work.
