У меня возникают проблемы с созданием формы для создания курса. Это часть моей схемы базы данных, для которой я пытаюсь создать форму:
Итак, что я пытаюсь сделать, это создать курс, где я могу создавать сеансы и даты (момент), прикрепленные к этому сеансу. Он должен выглядеть примерно так:
В моем классе CourseAdmin у меня есть:
protected function configureFormFields(FormMapper $formMapper)
{
$formMapper
->add('name', 'text', array('label' => 'Naam'))
->add('description', 'textarea', array('label' => 'Beschrijving'))
->add('materials', 'textarea', array('label' => 'Benodigde materialen'))
->add('numberOfParticipants', 'number', array('label' => 'Aantal deelnembers'))
->add('numberOfDays', 'number', array('label' => 'Aantal dagen'))
->add('price', 'number', array('label' => 'Prijs'))
->add('priceKmo', 'number', array('label' => 'KMO-portefeuille Prijs'))
->add('location', 'sonata_type_model', array('expanded' => true, 'by_reference' => false, 'multiple' => true, 'btn_add' => false))
->add('session', 'sonata_type_collection', array(
'by_reference' => false,
'type_options' => array(
// Prevents the "Delete" option from being displayed
'delete' => false,
'delete_options' => array(
// You may otherwise choose to put the field but hide it
'type' => 'hidden',
// In that case, you need to fill in the options as well
'type_options' => array(
'mapped' => false,
'required' => false,
)
)
)
), array(
'edit' => 'inline',
'inline' => 'table',
'sortable' => 'position'
))
;
}
В моем классе SessionAdmin у меня есть:
protected function configureFormFields(FormMapper $formMapper)
{
$formMapper
->add('type', 'text', array('label' => 'Type opleiding (Dag / Avond)'))
->add('moment', 'sonata_type_collection', array(
'by_reference' => false,
'type_options' => array(
// Prevents the "Delete" option from being displayed
'delete' => false,
'delete_options' => array(
// You may otherwise choose to put the field but hide it
'type' => 'hidden',
// In that case, you need to fill in the options as well
'type_options' => array(
'mapped' => false,
'required' => false,
)
)
)
), array(
'edit' => 'inline',
'inline' => 'table',
'sortable' => 'position'
))
;
}
И в моем классе MomentAdmin у меня есть:
protected function configureFormFields(FormMapper $formMapper)
{
$formMapper
->add('time', 'date', array('label' => 'Datum'))
;
}
Проблема в моей форме - когда я пытаюсь добавить момент (дату) в свою сессию, я получаю следующую ошибку:
FatalErrorException: Ошибка: вызов функции-члена getName() в нуле в строке /myproject/app/cache/dev/classes.php 9772
Итак, я могу добавить сеанс, но когда я пытаюсь добавить момент в свою сессию, я получаю сообщение об ошибке...
Когда я смотрю в файле classes.php в правиле 9771 и 9772, есть:
$childFormBuilder = $this->getChildFormBuilder($formBuilder, $elementId);
$fieldDescription = $admin->getFormFieldDescription($childFormBuilder->getName());
$childFormBuilder null.
Когда я смотрю на эту функцию, я получаю следующее:
public function getChildFormBuilder(FormBuilder $formBuilder, $elementId)
{
foreach (new FormBuilderIterator($formBuilder) as $name => $formBuilder) {
if ($name == $elementId) {
return $formBuilder;
}
}
return;
}
Когда я делаю var_dump из $name и $elementId следующим образом:
public function getChildFormBuilder(FormBuilder $formBuilder, $elementId)
{
foreach (new FormBuilderIterator($formBuilder) as $name => $formBuilder) {
var_dump("name: " . $name);
var_dump("elementId: " . $elementId);
if ($name == $elementId) {
return $formBuilder;
}
}
die;
return;
}
И нажмите на кнопку Добавить новую кнопку, как на следующем рисунке:
Затем я получаю этот вывод:
name: s56cda71d2daa0_name
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_description
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_materials
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_numberOfParticipants
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_numberOfDays
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_price
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_priceKmo
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_location
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_session
elementId: s56cda71d2daa0_session_0_moment
Во всех моих сущностях у меня есть функция __toString. Пример моего объекта курса:
public function __toString()
{
if(!is_null($this->name))
{
return $this->name;
}
else{
return "";
}
}
В чем может быть проблема? Я действительно застрял в этом. Я также разместил issue в реестре github администратора Sonata, но ответов нет...

UPDATE:
Я добавил несколько var_dumps к моей функции getChildFormBuilder следующим образом:
public function getChildFormBuilder(FormBuilder $formBuilder, $elementId)
{
foreach (new FormBuilderIterator($formBuilder) as $name => $formBuilder) {
if ($name == $elementId) {
return $formBuilder;
}
}
var_dump(__METHOD__);
var_dump($elementId);
var_dump(debug_backtrace());
return;
}

ОБНОВЛЕНИЕ 2:
Я изменил требование в моем composer.json на "sonata-project/admin-bundle": "^[email protected]" и обновил композитор. Но теперь я получаю эту ошибку:
ContextErrorException: предупреждение: недопустимое смещение строки 'admin' в app/cache/dev/classes.php строка 10482
Ошибка в этой функции:
public function getDashboardGroups()
{
$groups = $this->adminGroups;
foreach ($this->adminGroups as $name => $adminGroup) {
if (isset($adminGroup['items'])) {
foreach ($adminGroup['items'] as $key => $item) {
if (''!= $item['admin']) {
$admin = $this->getInstance($item['admin']);
if ($admin->showIn(Admin::CONTEXT_DASHBOARD)) {
$groups[$name]['items'][$key] = $admin;
} else {
unset($groups[$name]['items'][$key]);
}
}
else {
unset($groups[$name]['items'][$key]);
}
}
}
if (empty($groups[$name]['items'])) {
unset($groups[$name]);
}
}
return $groups;
}
Ошибки в строке: if (''!= $item['admin']) {.
В моем config.yml у меня есть:
sonata_admin:
title: Studyx
title_logo: bundles/studyxenrolment/images/logo.png
templates:
layout: StudyxEnrolmentBundle:Admin:standard_layout.html.twig
edit: StudyxEnrolmentBundle:CRUD:edit.html.twig
user_block: StudyxEnrolmentBundle:Admin:user_block.html.twig
# search: SonataAdminBundle:Core:search.html.twig
# search_result_block: SonataAdminBundle:Block:block_search_result.html.twig
dashboard:
groups:
studyx.admin.group.inschrijvingen:
label: Inschrijvingen
items: ~
item_adds:
- sonata.admin.enrolment
studyx.admin.group.algemeen:
label: Algemeen
items: ~
item_adds:
- sonata.admin.course
- sonata.admin.student
studyx.admin.group.extra:
label: Extra
items: ~
item_adds:
- sonata.admin.location
blocks:
-
position: top
class: col-md-12
type: sonata.admin.block.admin_list
Итак, я думаю, что там называется функция getDashboardGroups.
ОБНОВЛЕНИЕ 3:
В моем composer.json у меня есть следующее:
"sonata-project/block-bundle": "~2.3",
"sonata-project/admin-bundle": "^[email protected]",
"sonata-project/doctrine-orm-admin-bundle": "2.3.*",
"sonata-project/formatter-bundle": "^2.3"
Должен ли я обновить их все до ^[email protected]?
