Right way to handle relations between entities in forms - symfony

Question

I have a table stock which have relation 1:m with a table called warranty. I made this entity for stock table:
<?php
namespace StockBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Gedmo\Mapping\Annotation as Gedmo;
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Bridge\Doctrine\Validator\Constraints as DoctrineAssert;

use ProductBundle\Entity\NLength;
use ProductBundle\Entity\NWeight;
/**

class KStock {

protected $nlength;
/**

*/
protected $created;
/**

*/
protected $modified;
/**

*/
protected $deletedAt;
public function setProduct(\ProductBundle\Entity\Product $param) {
$this->product = $param;

public function setSku($param) {
$this->sku = $param;
}
public function getSku() {
return $this->sku;
}
public function setAvailability($param) {

}
public function getAvailability() {
return $this->availability;
}
public function setDescription($description) {

}
public function getDescription() {
return $this->description;
}
public function setPrice($param) {

}
public function getPrice() {

public function setWidth($width) {

public function setCreated($created) {

public function getCreated() {

public function setModified($modified) {

}
public function getModified() {

public function getDeletedAt() {
return $this->deletedAt;
}
public function setDeletedAt($deletedAt) {

public function setNWeight(\ProductBundle\Entity\NWeight $nweight) {

}
public function getNLength() {
return $this->nlength;
}
public function __toString() {
return $this->company . ' -- ' . $this->product;
}
}
And this entity for Warranty table:
<?php
namespace StockBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Gedmo\Mapping\Annotation as Gedmo;
/**
* #ORM\Entity
* #ORM\Table(name="warranty")
* #Gedmo\SoftDeleteable(fieldName="deletedAt")
*/
class Warranty {
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*
*/
protected $id;
/**
* #ORM\ManyToOne(targetEntity="Warranty")
* #ORM\JoinColumn(name="parent", referencedColumnName="id")
*/
protected $parent;
/**
* #ORM\ManyToOne(targetEntity="ProductBundle\Entity\Product")
* #ORM\JoinColumn(name="product", referencedColumnName="upc")
*/
protected $product;
/**
* #ORM\ManyToOne(targetEntity="StockBundle\Entity\NCondition")
* #ORM\JoinColumn(name="kcondition", referencedColumnName="id")
*/
protected $kcondition;
/**
* #ORM\ManyToOne(targetEntity="CompanyBundle\Entity\Company")
* #ORM\JoinColumn(name="company", referencedColumnName="id")
*/
protected $company;
/**
*
* #ORM\Column(type="date")
*/
protected $valid_time;
/**
*
* #ORM\Column(type="text")
*/
protected $description;
/**
* #Gedmo\Timestampable(on="create")
* #ORM\Column(name="created", type="datetime")
*/
protected $created;
/**
* #Gedmo\Timestampable(on="update")
* #ORM\Column(name="modified", type="datetime")
*/
protected $modified;
/**
* #ORM\Column(name="deletedAt", type="datetime", nullable=true)
*/
protected $deletedAt;
/**
* #ORM\OneToMany(targetEntity="StockBundle\Entity\KStock")
*/
protected $stocks;
public function getId() {
return $this->id;
}
public function setParent(Warranty $parent = null) {
$this->parent = $parent;
}
public function getParent() {
return $this->parent;
}
public function setDescription($description) {
$this->description = $description;
}
public function getDescription() {
return $this->description;
}
public function setCreated($created) {
$this->created = $created;
}
public function getCreated() {
return $this->created;
}
public function setModified($modified) {
$this->modified = $modified;
}
public function getModified() {
return $this->modified;
}
public function getDeletedAt() {
return $this->deletedAt;
}
public function setDeletedAt($deletedAt) {
$this->deletedAt = $deletedAt;
}
public function setProduct(\ProductBundle\Entity\Product $product) {
$this->product = $product;
}
public function getProduct() {
return $this->product;
}
public function setCompany(\CompanyBundle\Entity\Company $company) {
$this->company = $company;
}
public function getCompany() {
return $this->company;
}
public function setKCondition(\StockBundle\Entity\NCondition $condition) {
$this->kcondition = $condition;
}
public function getKCondition() {
return $this->kcondition;
}
public function setValidTime($valid_time) {
$this->valid_time = $valid_time;
}
public function getValidTime() {
return $this->valid_time;
}
}
Then I create my KStockType.php with this code:
<?php
namespace StockBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
use CatalogBundle\Form\KCatalogType;
class KStockType extends AbstractType {
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options) {
$builder->add('sku', 'text', array('required' => true, 'label' => 'SKU (Número de Referencia)'))
->add('price', 'money', array('label' => 'Precio', 'currency' => 'VEF'))
->add('unit', 'entity', array('label' => 'Moneda', 'class' => 'StockBundle:NUnit', 'property' => 'name', 'required' => true, 'multiple' => false, 'expanded' => false))
->add('amount', 'integer', array('label' => 'Cantidad'))
->add('status', 'entity', array('label' => 'Estado', 'class' => 'StockBundle:NStockStatus', 'property' => 'name', 'required' => true, 'multiple' => false, 'expanded' => false))
->add('condition', 'entity', array('label' => 'Condición del producto', 'class' => 'ProductBundle:NCondition', 'property' => 'name', 'required' => true, 'multiple' => false, 'expanded' => false))
->add('width', 'integer', array('required' => true, 'label' => 'Ancho'))
->add('height', 'integer', array('required' => true, 'label' => 'Alto'))
->add('length', 'integer', array('required' => true, 'label' => 'Largo'))
->add('nlength', 'entity', array('label' => 'Unidad de Medida', 'class' => 'ProductBundle:NLength', 'property' => 'name', 'required' => true, 'multiple' => false, 'expanded' => false))
->add('weight', 'integer', array('required' => true, 'label' => 'Peso'))
->add('nweight', 'entity', array('label' => 'Unidad de Peso', 'class' => 'ProductBundle:NWeight', 'property' => 'name', 'required' => true, 'multiple' => false, 'expanded' => false))
->add('description', 'textarea', array('label' => 'Descripción'))
->add('start_date', 'date', array('label' => 'Fecha (Inicio de la Publicación)', 'widget' => 'single_text', 'format' => 'yyyy-MM-dd', 'attr' => array('class' => 'dpicker')))
->add('warranty', 'textarea', array('required' => true, 'label' => 'Condiciones de Garantía'))
->add('valid_time', 'date', array('label' => 'Tiempo de Validez de la Garantía', 'widget' => 'single_text', 'format' => 'yyyy-MM-dd', 'attr' => array('class' => 'dpicker')));
}
/**
* #param OptionsResolverInterface $resolver
*/
public function setDefaultOptions(OptionsResolverInterface $resolver) {
$resolver->setDefaults(array(
'data_class' => 'StockBundle\Entity\KStock'
));
}
/**
* #return string
*/
public function getName() {
return 'stockbundle_kstock';
}
}
As you may notice I have some fields on that form that belongs to warranty. Then in my controller I have this method for edit action:
/**
* Stock
*
* #Route("/edit/{company_id}/{product_id}", name="stock_edit")
* #Method("GET")
*/
public function editAction($company_id, $product_id) {
$em = $this->getDoctrine()->getManager();
$entity = $em->getRepository('StockBundle:KStock')->findOneBy(array('company' => $company_id, 'product' => $product_id));
$response = array();
$response["response"] = true;
if (!$entity) {
$response['response'] = FALSE;
$response['message'] = 'Unable to find Stock entity.';
return new JsonResponse($response);
}
$product = $em->getRepository('ProductBundle:Product')->find($product_id);
$company = $em->getRepository('CompanyBundle:Company')->find($company_id);
if (!$product || !$company) {
$response['response'] = FALSE;
$response['message'] = 'Error not found product or company';
return new JsonResponse($response);
}
$editForm = $this->createForm(new KStockType(), $entity);
return $this->render("StockBundle:Stock:edit.html.twig", array('entity' => $entity, 'edit_form' => $editForm->createView()));
}
But when I call it I got this error:
Neither the property "start_date" nor one of the methods
"getStartDate()", "isStartDate()", "hasStartDate()", "_get()" or
"_call()" exist and have public access in class
"StockBundle\Entity\KStock".
What I am missing?

Answer 1

Take a look at this page: Symfony documentation
A little brief from that:
In more complex examples, you can embed entire forms, which is useful when
creating forms that expose one-to-many relationships
I think you have two possible aproaches:
1 - Look how to make forms with relational entities
2 - Make a form without a class and manage all information in your controller ( I wouldn't use this)

Answer 2

Try to replace your line about start_date in your form by:
->add('start_date', 'date', array('label' => 'Fecha (Inicio de la Publicación)', 'widget' => 'single_text', 'format' => 'yyyy-MM-dd', 'attr' => array('class' => 'dpicker'), 'mapped' => false))
