恢复值 select 输入相关实体学说 symfony 2

Question

我正在尝试根据 Symfony 2 的相关实体创建一个表单。我有不同的实体：Tematica、Personal、Hilo、Consultante、Consulta、Consulta_Asignatura 和 Asignatura。我试图保留我的所有数据，但实体 Hilo Personal 和 Tematica 存在一些问题。在我的表单中需要显示 select 输入，它应该有所有 "Enunciado" 行，然后在这个 select 输入中恢复 selected 选项的电子邮件。我会分享我的代码，希望有人能帮助我。

class HiloType extends AbstractType
{
    /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('consultanteemail', new ConsultanteType(), array ('label' => false))
            ->add('personalemail', 'entity', array(
                'label' => 'Personal de Soporte',
                'class' => 'GuiasDocentes\AppBundle\Entity\Personal',
                'property' => 'Email',
                'by_reference' => 'false',
                'query_builder' => function(PersonalRepository $pr) {
                    $query= $pr->createQueryBuilder('u')
                    ;
                    return $query;
                },
                'empty_value' => 'Elige un perfil de consulta:',
                ))
            // ->add('personalemail', new PersonalType(), array ('label' => false))
        ;

/* End customized code */

与您在此过程中看到的方式相同，我得到 select 由个人 class 的电子邮件生成的字段，您需要显示 Tematica_soporte class 的 Enunciado . 萨克斯

Answer 1

以这种方式在 TematicaSoporte 中添加一个方法就足够了：

public function getEnunciado(){ return $this->getTematicasSoporte()[0]->getEnunciado(); }
