Symfony 2.3.6 nested forms

I am trying to have a form with a collection of forms that will allow me to fill in weekly data. I have an Entity that is for the week with a few stats

/**
 * @ORM\Column(type="integer", nullable=false)
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="IDENTITY")
 */
protected $week_id;

/**
 * @ORM\Column(type="string")
 */
protected $area_worked;

/**
 * @ORM\OneToMany(targetEntity="User")
 */
protected $approved_by;

/**
 * @ORM\OneToMany(targetEntity="DailyStats")
 */
protected $daily_stats;

Then i have the daily stats entity:

/**
 * @ORM\Column(type="integer", nullable=false)
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="IDENTITY")
 */
protected $day_id;

/**
 * @ORM\ManyToOne(targetEntity="WeeklyStats")
 */
protected $weekly_stat_id;

/**
 * @ORM\Column(type="float")
 */
protected $hours_worked;

/**
 * @ORM\Column(type="integer")
 */
protected $day_of_week;

Then with both of these i want a form that i can output into a table showing the whole week:

         Monday | Tuesday | Wednesday | Thursday | Friday | Saturday | Sunday
Hours  |        |         |           |          |        |          |

However when i put this into a form:

//weekly stats form

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder->add('dailyReports', 'collection',array(
            'type'=>new DailyStatsForm(),
            'options'  => array(
                'required'  => false
            ),
            'allow_add' => true,
        ));
}

this generates a form with an empty field set. I can use the javascript to add a field to it but I want to know if its possible to just always generate the 7 days in a keep for this form along with the other fields for the weekly stats?

Any suggestions of solutions would be greatly appreciated.

Yes you can, look at the documentation, if you add seven DailyStats entities to your week entity then symfony2 will render those seven inputs that you want, please check http://symfony.com/doc/current/cookbook/form/form_collections.html

class TaskController extends Controller
{   
      public function newAction(Request $request)
      {
           $task = new Task();

           // dummy code - this is here just so that the Task has some tags
           // otherwise, this isn't an interesting example
           $tag1 = new Tag();
           $tag1->name = 'tag1';
           $task->getTags()->add($tag1); // any new related entity you add represents a new embeded form
           $tag2 = new Tag();
           $tag2->name = 'tag2';
           $task->getTags()->add($tag2);
           // end dummy code

           $form = $this->createForm(new TaskType(), $task);

           $form->handleRequest($request);

           if ($form->isValid()) {
               // ... maybe do some form processing, like saving the Task and Tag objects
           }

           return $this->render('AcmeTaskBundle:Task:new.html.twig', array(
               'form' => $form->createView(),
           ));
     }
}
