恢复值选择输入相关实体学说符号2

Question

我正试图根据Symfony 2原理中的相关实体创建一个表单。我有不同的实体：Tematica、Personal、Hilo、Consultante、Consulta、Consulta_Signatura和Asignatura。我坚持我的所有数据，然而与实体Hilo Personal和Tematica有一些问题。在我的表单中，需要显示选择输入，它应该有所有的"Enunciado"行，然后在这个选择输入中恢复所选选项的电子邮件。我会分享我的代码，我希望有人能帮助我。

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' => 'GuiasDocentesAppBundleEntityPersonal',
                '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))

正如你在这个过程中看到的那样，我得到了用Personal类的电子邮件生成的select字段，y需要显示Tematic_oporte类的Enunciado。Thax

Answer 1

在TematicSoporte中以这种方式添加一个方法就足够了：

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