Symfony3 - Embedded collection form is empty when displayed - forms

Question

I'm creating a timecard form which has 14 dayslots, one for each day slot.
I have created the entities, controller and formType. In the new action of the controller of the timecard, I create 14 instances of the dayslot and add them to the timecard using the entity function. The form comes up empty - as if the collection is empty. Is there something more I have to do? It seems that the form is not properly bound to the entity collection objects. I have dumped the entity before displaying it seems to be there.
Here is the TimeCard Entity:
<?php
namespace CockpitBundle\Entity;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;
/**

*/
class TCTimeCard

Here is the DaySlot entity (TCDaySlot)

And here is the controller TCTimeCardController
/**

public function newAction(Request $request)
{
$tcTimeCard = new TCTimeCard();
$em = $this->getDoctrine()->getManager();
$periodStart = $em->getRepository('CockpitBundle:TCTimeCard')->getBestDate();
$username = $this->getUser()->getUsername();
$employee = $em->getRepository('CockpitBundle:Employee')->findOneByUsername($username);
$status = $em->getRepository('CockpitBundle:TCStatus')->findOneById(1);
$tcTimeCard->setPeriodBegin($periodStart);
$tcTimeCard->setStatus($status);
$tcTimeCard->setEmployee($employee);
$form = $this->createForm('CockpitBundle\Form\TCTimeCardType', $tcTimeCard);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$cnt=0;
foreach($form->get('tcdayslots') as $slotform) {
print "Cnt =". ++$cnt . "<BR>";
}
$em->persist($tcTimeCard);
$em->flush();
die("done");
return $this->redirectToRoute('tctimecard_show', array('id' => $tcTimeCard->getId()));
}
$days = ['Sun','Mon','Tue','Wed','Thu','Fri','Sat'];
$headings = ['-2' => 'Regular','-1' => "Overtime", '0' => "Holiday"];
foreach ($em->getRepository('CockpitBundle:TimeOffType')->findAll() as $tot) {
$headings[$tot->getId()] = $tot->getType();
}
$headings['99'] = "Comments";
$date = $periodStart;
for ($i = 1; $i<=2; $i++) {
foreach ($days as $day) {
$tcDaySlot = new \CockpitBundle\Entity\TCDaySlot;
$tcDaySlot->setDate($date->format('Y-m-d'));
//$tcsForm = $this->slotForm($tcDaySlot,$date,$employee)->createView();
//$tcsForms[$date->format('m/d/y')] = $tcsForm;
$dates[$date->format('m/d/y')] = $day;
$date->add(new \DateInterval('P1D'));
$tcTimeCard->addTcdayslot($tcDaySlot);
}
}
$cnt2 =0;
foreach ($tcTimeCard->getTcdayslots() as $dayslot) {
print "Cnt2 = " . ++$cnt2 . " " . $dayslot->getDate() . "<BR>";
}
dump($form->getData());
return $this->render('tctimecard/new.html.twig', array(
'tCTimeCard' => $tcTimeCard,
'form' => $form->createView(),
'headings' => $headings,
'emp' => $employee,
'dates' => $dates,
));
}
Lastly, here is the twig I am using to display the form
{% extends 'base.html.twig' %}
{% block body %}
<div class="status">
<h1>Time Card for {{ emp.displayname }} Period Beginning: {{ dates|keys|first }}</h1>
</div>
keys = {{form|keys|join('|') }}<BR>
{{ form_start(form) }}
{{ form_widget(form) }}
<table class="timecard">
<tr>
<th>Date</th>
{% for id,heading in headings %}
<th class="tcheader">
{{ heading}}
</td>
{% endfor %}
</tr>
Length = {{ form.tcdayslots|length }}
{% for tcdayslot in form.tcdayslots %}
<tr>
{% if day | slice(0,1) == 'S' %}
<td class="weekend">{{ date }} {{ day }}</td>
{% else %}
<td>{{ date }} {{ day }}{{ form_start(tcdayslot) }}</td>
{% endif %}
<td>
{{ form_row(tcdayslot.reghours) }}

<td>
{{ form_row(tcdayslot.othours) }}

Answer 1

I finally figured out what was going on. The following line in the foreach $days loop:
$tcDaySlot = new \CockpitBundle\Entity\TCDaySlot;
does not call the constructor. I changed it to:
$tcDaySlot = TCDaySlot();
and added a use statement for the entity and that seems to have connected the collection properly. I think it is a static class instantiation instead of an instance of the object or was I just missing the parens?
I also had to remove the form_start and form_end for each collection object in the twig, as there is only one form created (duh, you can't have embedded forms in HTML).
