Symfony error when inserting new entity data

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;

        /**

         *

        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.
