I'm using a custom Widget for date fields, and I want to use it in all my forms. The problem is that symfony uses the default sfWidgetFormDate. What I want is to change this default widget in order to generate forms with my custom Widget. I don't want to change by hand all the forms generated.

The only approach I have found is the treak of modify BaseFormDoctrine.php:

public function setup()
{
    foreach($this->getWidgetSchema()->getFields() as $name=>$widget)
    {
        if($widget instanceof sfWidgetFormDate) 
        {
            $this->widgetSchema[$name] = new sfWidgetFormJQueryDate(array(
                'config' => '{}',
                'image'=>'/images/calendar.png',
            ));
        }
    }
}
