function executeMoo(sfWebRequest $request) {
$this->forms = array();

$it = 0;

foreach($some_model as $s) {

$f = new MooForm($s);

$f->getWidgetSchema()->setNameFormat('foo[' . $form->getName() . $it . '][%s]');

$this->form->embedForm($it, $form);
$this->forms[] = $this->form;
$it++;

}
}

The presentation part should be as simple as:

<form ...>
<table>
<tr>
<td><table>
<?php
foreach($forms as $form) :
   echo $form;
endforeach;
?>
</table></td>
</tr>
</table>
</form>
</pre>

Ok now for the validation part:

public function executeSubmit_Foo(sfWebRequest $request) {
         $this->forward404Unless($request->isMethod(sfRequest::POST));

   	$base_forms = $request->getParameter('foo');

	foreach($base_forms as $base_form) {
		$f = new MooForm();
		$f->bind($base_form,null);
		if($f->isValid()) {
			$f->save();
		}
	}
}

What’s the catch?
Well the catch is in this line: $f->getWidgetSchema()->setNameFormat(‘foo[' . $form->getName() . $it . '][%s]‘);
What it really does? it generates the form fields like foo['forms_name1'] … so the only thing you have to do is grabbing the foo var from request and looping through to get the embedded forms.
Sure there are better ways, but this worked nice with a minimum ammount of time spent.
Hope it helps.

}

The usage of the above class should be something like this:

$query = Custom_Doctrine_Query::create()->from('TargetTable t');
$count = $query->count();

or the bulky way omitting the static create method:

$query = Doctrine_Query::create(null, 'Custom_Doctrine_Query')->from('TargetTable t');
$count = $query->count();

The result of the above queries should be something like “SELECT COUNT(index_field) from target_table”.
