Geschachtelte Sammlungsfelder in Sonata Admin (2.3)
Ich habe Probleme beim Erstellen meines Formulars zum Erstellen eines Kurses. Dies ist ein Teil meines Datenbankschemas, für das ich ein Formular erstellen möchte:
Ich versuche also, einen Kurs zu erstellen, in dem ich Sitzungen und Daten (Momente) erstellen kann, die mit dieser Sitzung verknüpft sind. Es sollte ungefähr so aussehen:
In meinem CourseAdmin Klasse, die ich habe:
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'
))
;
}
In meinem SessionAdmin Klasse, die ich habe:
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'
))
;
}
nd in meinem MomentAdmin Klasse, die ich habe:
protected function configureFormFields(FormMapper $formMapper)
{
$formMapper
->add('time', 'date', array('label' => 'Datum'))
;
}
Das Problem in meinem Formular besteht darin, dass beim Versuch, meiner Sitzung einen Moment (ein Datum) hinzuzufügen, die folgende Fehlermeldung angezeigt wird:
FatalErrorException: Fehler: Aufruf einer Mitgliedsfunktion getName () auf null in /myproject/app/cache/dev/classes.php Zeile 9772
So kann ich eine Sitzung hinzufügen, aber wenn ich versuche, meiner Sitzung einen Moment hinzuzufügen, wird der Fehler angezeigt ...
Wenn ich in die Datei schaue classes.php auf Regel 9771 und 9772 gibt es:
$childFormBuilder = $this->getChildFormBuilder($formBuilder, $elementId);
$fieldDescription = $admin->getFormFieldDescription($childFormBuilder->getName());
Das$childFormBuilder istNul.
Wenn ich mir diese Funktion anschaue, bekomme ich Folgendes:
public function getChildFormBuilder(FormBuilder $formBuilder, $elementId)
{
foreach (new FormBuilderIterator($formBuilder) as $name => $formBuilder) {
if ($name == $elementId) {
return $formBuilder;
}
}
return;
}
Wenn ich einen var_dump von $ name und $ element mache, sieht das so aus:
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 $formBuilder;
}
}
die;
return;
}
Und klicken Sie auf die Schaltfläche Add new (Neu hinzufügen), wie in der folgenden Abbildung dargestellt:
Dann bekomme ich diese Ausgabe:
name: s56cda71d2daa0_name
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_description
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_materials
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_numberOfParticipants
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_numberOfDays
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_price
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_priceKmo
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_location
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_session
elementId: s56cda71d2daa0_session_0_moment
In all meinen Entitäten habe ich eine __toString-Funktion. Ein Beispiel in meiner Kursentität:
public function __toString()
{
if(!is_null($this->name))
{
return $this->name;
}
else{
return "";
}
}
Was könnte hier das Problem sein? Ich bleibe wirklich dabei. Ich habe auch ein @ gepostProble auf dem Github-Repo von Sonata Admin, aber keine Antworten ...

AKTUALISIEREN
Ich habe meiner Funktion ein paar var_dumps hinzugefügt getChildFormBuilder so was
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;
}

UPDATE 2:
Ich habe die Anforderung in meiner composer.json in "sonata-project / admin-bundle" geändert: "^2.4@dev" und mit composer aktualisiert. Aber jetzt bekomme ich diesen Fehler:
ContextErrorException: Warnung: Unzulässiger String-Offset 'admin' in Zeile 10482 von app / cache / dev / classes.p
Der Fehler ist in dieser Funktion:
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;
}
Die Fehler in der Zeile:if (''!= $item['admin']) { .
In meinem config.yml Ich habe
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
So ich denke die funktion getDashboardGroupsort heißt @.
UPDATE 3:
In meinem composer.json Ich habe jetzt folgendes:
"sonata-project/block-bundle": "~2.3",
"sonata-project/admin-bundle": "^2.4@dev",
"sonata-project/doctrine-orm-admin-bundle": "2.3.*",
"sonata-project/formatter-bundle": "^2.3"
Sollte ich sie alle auf @ update^2.4@dev ?
