插入新实体数据时出现 Symfony 错误

Question

我是学习 Symfony 的初学者。我有一个名为 sale 的实体，我有一个用于插入销售数据的表单。

问题是每次尝试插入数据都会导致以下错误：

既不是“selectedstock”属性也不是其中一种方法 "addSelectedstock()"/"removeSelectedstock()", "setSelectedstock()", “selectedstock()”、“__set()”或“__call()”存在并公开 在“iCerge\Salesdeck\SalesBundle\Entity\Sale”类中访问。

我的Sale类如下：

<?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;

        /**

         *

以下是我的 Form 类：

<?php

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(

                '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';
    }

}

我在这里做错了什么？

更新

屏幕截图显示可用库存的下拉列表。 该表单是销售/添加表单，需要从列表中选择一项可用库存。

您没有selectedstock的setter，与您没有注释将selectedstock标记为orm列的错误无关，因此不会持久化。
