Recover values select imput related entities doctrine symfony 2

问题

I'm trying to create a form based on my related entities in doctrine by Symfony 2. I have different entities: Tematica, Personal, Hilo, Consultante, Consulta, Consulta_Asignatura and Asignatura. I reach to persist all my data, nevertheless have some problems with entities Hilo Personal and Tematica. In my form need to show select imput, it should have all "Enunciado" rows and later recover Email of selected option in this select input. I'll share my code, I hope somebody can help my.

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))
        ;

In the same way that you can see with this process I get select field generated with email of Personal class y need to show Enunciado of Tematica_soporte class. Thax

回答1:

Was enough with add a method inside TematicaSoporte in this way:

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