Get and set the current value from the relationship between "maquina" and "emisor"

Related to this topic and this other topic I'm experimenting a issue. This is the SdrivingMaquinForm.class.php code:

class SdrivingMaquinaForm extends BaseSdrivingMaquinaForm {

    protected $current_user;

    public function configure() {
        $this->current_user = sfContext::getInstance()->getUser()->getGuardUser();

        unset($this['updated_at'], $this['created_at']);

        $this->widgetSchema['idempresa'] = new sfWidgetFormInputHidden();
        $id_empresa = $this->current_user->getSfGuardUserProfile()->getIdempresa();
        $this->setDefault('idempresa', $id_empresa);

        $this->widgetSchema['no_emisor'] = new sfWidgetFormDoctrineChoice(array('model' => 'SdrivingEmisor', 'add_empty' => 'Seleccione un Emisor', 'table_method' => 'fillChoice'));
        $this->validatorSchema['idempresa'] = new sfValidatorPass();
        $this->validatorSchema['no_emisor'] = new sfValidatorPass();
    }

    protected function doUpdateObject($values) {
        parent::doUpdateObject($values);

        if (isset($this['no_emisor'])) {
            if ($this->isNew()) {
                $sdrivingMaquinaEmisor = new SdrivingMaquinaEmisor();
                $this->getObject()->setSdrivingMaquinaEmisor($sdrivingMaquinaEmisor);
            } else {
                $sdrivingMaquinaEmisor = $this->getObject()->getSdrivingMaquinaEmisor();
            }

            $sdrivingMaquinaEmisor->setIdemisor($this->values['no_emisor']);
        }
    }

}

And it works perfectly, if I create a new maquina values are saved correctly, if I edit a existent record once again values are saved correctly and if I delete a record then the relation is deleted too. So the problem is not in actions or method. The problem I'm having is when user select to edit the existent record. Field idempresa and patente (see the schema.yml at first post metioned here) gets theirs values but no_emisor doesn't so every time I want to edit the record I got the select with values, yes, but the selected value isn't the right because I get the add_empty value. How I fix that? Meaning how I assign the default value for the select based on the one existent on the relation between maquina and emisor?

EDIT: working on a possible solution

I'm trying this code:

public function executeEdit(sfWebRequest $request) {
        $this->forward404Unless($sdriving_maquina = Doctrine_Core::getTable('SdrivingMaquina')->find(array($request->getParameter('idmaquina'))), sprintf('Object sdriving_maquina does not exist (%s).', $request->getParameter('idmaquina')));
        $this->forward404Unless($sdriving_maquina_emisor = Doctrine_Core::getTable('SdrivingMaquinaEmisor')->find(array($request->getParameter('idmaquina'))), sprintf('Object sdriving_maquina_emisor does not exist (%s).', $request->getParameter('idmaquina')));

        $this->form = new SdrivingMaquinaForm($sdriving_maquina, $sdriving_maquina_emisor);
    }

But then how in the form configure() method I can access to $sdriving_maquina_emisor in order to use form setDefault() method?

EDIT: doUpdateObject($values)

See this is how my doUpdateObject($values) function looks like:

protected function doUpdateObject($values) {
    parent::doUpdateObject($values);

    if (isset($this['no_emisor'])) {
        if ($this->isNew()) {
            $sdrivingMaquinaEmisor = new SdrivingMaquinaEmisor();
            $this->getObject()->setSdrivingMaquinaEmisor($sdrivingMaquinaEmisor);
        } else {
            $sdrivingMaquinaEmisor = $this->getObject()->getSdrivingMaquinaEmisor();
        }

        $sdrivingMaquinaEmisor->setIdemisor($this->values['no_emisor']);
    }
}

Where exactly feet the code you leave for doUpdateObject()?

In these situations you always have to do 2 things:

  • load the default value from the doctrine record object into the form widget
  • update the doctrine object with the posted value

And most of the times you should use updateDefaultsFromObject and doUpdateObject symmetrically.

To load back the saved values override updateDefaultsFromObject:

// maybe you have to declare it as public if the parent class requires that
protected function updateDefaultsFromObject()
{
  parent::updateDefaultsFromObject();

  if (isset($this['no_emisor'])
  {
    $this->setDefault('no_emisor', $this->getObject()->getSdrivingMaquinaEmisor()->getIdemisor());
  }
}

// and you can simplify this a little bit as well
protected function doUpdateObject($values)
{
  parent::doUpdateObject($values);

  if (isset($this['no_emisor']))
  {
    $this->getObject()->getSdrivingMaquinaEmisor()->setIdemisor($this->values['no_emisor']);
  }
}
