最终使用未映射的人员选择字段和 javascript 来自动更新数据(使用 ajax)来解决它。
参与者/add.twig:
{% block javascripts %}
<script type="text/javascript">
$(document).ready(function () {
function onTrainerChange() {
let trainerId = $('#participant_person_choose').val();
$.get(Routing.generate('person_data_ajax', { id: trainerId }), function (data) {
$('#participant_person_gender').val(data.gender);
$('#participant_person_title').val(data.title);
$('#participant_person_firstName').val(data.firstName);
$('#participant_person_lastName').val(data.lastName);
$('#participant_person_email').val(data.email);
$('#participant_person_telephone').val(data.telephone);
if (data.company) {
let company = $('#participant_person_company');
company.empty();
company.append(new Option(data.company.text, data.company.id));
company.val(data.company.id);
company.trigger('change');
// manipulate dom directly because of .select('data') bug with select2 >=4.0
}
});
};
let trainer = $('#participant_person_choose');
trainer.change(onTrainerChange);
});
</script>
{% endblock %}
参与者控制器添加:
$participant = new Participant($seminar);
$person = $participant->getPerson() ?? new Person();
$participant->setPerson($person);
$form = $this->createParticipantForm($participant)
->add('person_choose', AjaxEntityType::class, [
'mapped' => false,
'class' => Person::class,
'remote_route' => 'person_select_ajax',
'placeholder' => 'form.personCreate',
'label' => 'form.person'
])
->add('person', PersonType::class);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
if ($form->get('reservation')->getData()) {
$participant->setInterested();
}
$personEntered = $form->get('person')->getData();
$personChosen = $form->get('person_choose')->getData();
if ($personChosen) {
$person = $personChosen;
$person->setGender($personEntered->getGender());
$person->setTitle($personEntered->getTitle());
$person->setFirstName($personEntered->getFirstName());
$person->setFirstName($personEntered->getLastName());
$person->setCompany($personEntered->getCompany());
$person->setEmail($personEntered->getEmail());
$person->setTelephone($personEntered->getTelephone());
$participant->setPerson($person);
}
$this->getDoctrine()->getManager()->persist($person);
$this->getDoctrine()->getManager()->persist($participant);
}
PersonController Ajax:
/**
* @Route("/{id}/data", name="person_data_ajax", methods={"GET"}, options={"expose": true})
*/
public function dataAjax(Person $person, PhoneNumberHelper $phonenumberHelper)
{
$arr = [
'id' => $person->id,
'gender' => $person->getGender(),
'title' => $person->getTitle(),
'firstName' => $person->getFirstName(),
'lastName' => $person->getLastName(),
'email' => $person->getEMail(),
'telephone' => $person->getTelephone() ? $phonenumberHelper->format($person->getTelephone(), PhoneNumberFormat::NATIONAL) : null,
'company' => $person->getCompany() ? [
'id' => $person->getCompany()->id,
'text' => $person->getCompany()->__toString()
] : null
];
return new JsonResponse($arr);
}
希望这可以帮助别人。对 Symfonys 表单的有限性感到非常失望。
