Rendering same form repeated in Symfony for bulk insert - symfony1

Question

I been trying all day to do multiple insert for the same form based on a number and i couldn't go any where with it. I hope someone here would be help me out...
am using admin generator on 1.4 doctrine. I have a form which i generated with only two fields. what am trying to do is, based on a number inserted the form will be repeated x number of times.
In the generator file I added a partial which placed a text field in the beginning of the form with default value of 1. If I choose 2 the form below gets duplicated twice..
Here is what i did to my form.. In action
class prizesActions extends autoPrizesActions
{
public function executeNew(sfWebRequest $request)
{
$this->form = $this->configuration->getForm(null, array('n' => 5));
$this->prizes = $this->form->getObject();
}
}
and in the PrizesForm, I wrote the following
class PrizesForm extends BasePrizesForm
{
public function configure()
{
$array = $this->getOptions();
for ($i = 0; $i < $array['n']; $i++) {
$this->setWidgets(array(
'id' => new sfWidgetFormInputHidden(),
'prize_no' => new sfWidgetFormInputText(),
'prize' => new sfWidgetFormInputText(),
'created_at' => new sfWidgetFormDateTime(),
'updated_at' => new sfWidgetFormDateTime(),
));
$this->setValidators(array(
'id' => new sfValidatorDoctrineChoice(array('model' => $this->getModelName(), 'column' => 'id', 'required' => false)),
'prize_no' => new sfValidatorInteger(array('required' => false)),
'prize' => new sfValidatorString(array('max_length' => 200, 'required' => false)),
'created_at' => new sfValidatorDateTime(),
'updated_at' => new sfValidatorDateTime(),
));
$this->widgetSchema->setNameFormat('prizes['.$i.'][%s]');
$this->errorSchema = new sfValidatorErrorSchema($this->validatorSchema);
}
unset( $this['updated_at'],
$this['created_at']
);
}
}
I think the loop is working but its over writing the widgets at every entry and i cannot find other method to append instead. Any ideas?
Thanks,

Did you try embedForm()? Code below should give you an idea.
class PrizesForm extends BasePrizesForm
{
public function configure()
{
$this->setWidgets(array(
'id' => new sfWidgetFormInputHidden(),
'prize_no' => new sfWidgetFormInputText(),
'prize' => new sfWidgetFormInputText(),
'created_at' => new sfWidgetFormDateTime(),
'updated_at' => new sfWidgetFormDateTime(),
));
$this->setValidators(array(
'id' => new sfValidatorDoctrineChoice(array('model' => $this->getModelName(), 'column' => 'id', 'required' => false)),
'prize_no' => new sfValidatorInteger(array('required' => false)),
'prize' => new sfValidatorString(array('max_length' => 200, 'required' => false)),
'created_at' => new sfValidatorDateTime(),
'updated_at' => new sfValidatorDateTime(),
));
$this->widgetSchema->setNameFormat('prizes[%s]');
}
}
class PrizesGroupForm extends sfForm
{
public function configure()
{
$array = $this->getOptions();
for ($i = 0; $i < $array['n']; $i++)
{
$this->embedForm('prizes_' . $i, new PrizesForm());
}
$this->widgetSchema->setNameFormat('prizes_group[%s]');
}
}
