Symfony error when inserting new entity data - symfony

Question

I am a beginner learning Symfony. I have an entity called sale for which I a form for inserting sales data.
The problem is each attempt to insert data results in the following error:
Neither the property "selectedstock" nor one of the methods
"addSelectedstock()"/"removeSelectedstock()", "setSelectedstock()",
"selectedstock()", "__set()" or "__call()" exist and have public
access in class "iCerge\Salesdeck\SalesBundle\Entity\Sale".
My Sale class is as follows:
<?php
namespace iCerge\Salesdeck\SalesBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Sales
*
* #ORM\Table()
* #ORM\Entity(repositoryClass="iCerge\Salesdeck\SalesBundle\Entity\SalesRepository")
*/
class Sale
{
private $selectedstock;
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var float
*
* #ORM\Column(name="cost", type="float")
*/
private $cost;
/**
* #var float
*
* #ORM\Column(name="profitloss", type="float")
*/
private $profitloss;
/**
* #var \DateTime
*
* #ORM\Column(name="date", type="datetime")
*/
private $date;
/**
* #ORM\ManyToOne(targetEntity="iCerge\Salesdeck\StockBundle\Entity\Stock", inversedBy="sales")
* #ORM\JoinColumn(name="sid", referencedColumnName="id")
*/
protected $stock;
/**
* #var integer
*
* #ORM\Column(name="number_of_purchases", type="integer")
*/
private $number_of_purchases;
/**
* #var float
*
* #ORM\Column(name="active_buy_price", type="float")
*/
private $active_buy_price;
/**
* #var integer
*
* #ORM\Column(name="sid", type="integer")
*/
private $sid;
/**
* Get sid
*
* #return integer
*/
public function getSid()
{
return $this->sid ? $this->sid : 0;
}
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set cost
*
* #param float $cost
* #return Sales
*/
public function setCost($cost)
{
$this->cost = $cost;
return $this;
}
/**
* Get cost
*
* #return float
*/
public function getCost()
{
return $this->cost;
}
/**
* Set date
*
* #param \DateTime $date
* #return Sales
*/
public function setDate($date)
{
$this->date = $date;
return $this;
}
/**
* Get date
*
* #return \DateTime
*/
public function getDate()
{
return $this->date;
}
/**
* Set profitloss
*
* #param float $profitloss
* #return Sales
*/
public function setProfitloss($profitloss)
{
$this->profitloss = $profitloss;
return $this;
}
/**
* Get profitloss
*
* #return float
*/
public function getProfitloss()
{
return $this->profitloss;
}
/**
* Set stock
*
* #param \iCerge\Salesdeck\StockBundle\Entity\Stock $stock
* #return Sale
*/
public function setStock(\iCerge\Salesdeck\StockBundle\Entity\Stock $stock = null)
{
$this->stock = $stock;
return $this;
}
/**
* Get stock
*
* #return \iCerge\Salesdeck\StockBundle\Entity\Stock
*/
public function getStock()
{
return $this->stock;
}
/********************/
/**
* Set number_of_purchases
*
* #return integer
*/
public function setNumberOfPurchases($purchases)
{
$this->number_of_purchases = $purchases;
return $this;
}
/**
* Get number_of_purchases
*
* #return integer
*/
public function getNumberOfPurchases()
{
return $this->number_of_purchases;
}
/**
* Set active_buy_price
*
* #return integer
*/
public function setActiveBuyPrice($price)
{
$this->active_buy_price = $price;
return $this;
}
/**
* Get active_buy_price
*
* #return integer
*/
public function getActiveBuyPrice()
{
return $this->active_buy_price;
}
public function getselectedstock()
{
return $this->selectedstock;
}
}
And the following is my Form class:
<?php
namespace iCerge\Salesdeck\SalesBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class SalesType extends AbstractType
{
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('selectedstock', 'choice', array(
'choices' => $options['allow_extra_fields'],
'required' => true,
'empty_value' => 'Choose a Product',
'empty_data' => null,
'label' => 'Select Item',
// 'mapped'=>false
))
/*->add('test', 'choice', array(
'choices' => $options['allow_extra_fields'],
'required' => false,
'empty_value' => 'Choose your gender',
'empty_data' => null,
'mapped'=>false
))*/
->add('number_of_purchases', 'integer', array('label'=>'Number of purchases'))
->add('cost')
->add('profitloss', 'text', array('label'=>'Profit/Loss'))
->add('date', 'datetime', array('data'=>new \DateTime('now')))
;
}
/**
* #param OptionsResolverInterface $resolver
*/
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
// 'data_class' => 'iCerge\Salesdeck\SalesBundle\Entity\Sales'
'data_class' => 'iCerge\Salesdeck\SalesBundle\Entity\Sale'
));
}
/**
* #return string
*/
public function getName()
{
return 'icerge_salesdeck_salesbundle_sales';
}
}
What am I doing wrong here?
Update
Screenshot shows dropdown list of available stock.
The form is the sales/add form which requires an item of available stock from the list to be selected.

Answer 1

You don't have a setter for selectedstock, and not related to the error you don't have annotation to mark selectedstock as an orm column, so it won't be persisted.
