Campos de colección anidados en Sonata Admin (2.3)
Tengo problemas para crear mi formulario para crear un curso. Esta es una parte de mi esquema de base de datos para el que estoy tratando de crear un formulario:
Entonces, lo que intento hacer es crear un curso donde pueda crear sesiones y fechas (momento) adjuntas a esa sesión. Debería verse más o menos así:
En miCourseAdmin clase que tengo:
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'
))
;
}
En miSessionAdmin clase que tengo:
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'
))
;
}
Y en miMomentAdmin clase que tengo:
protected function configureFormFields(FormMapper $formMapper)
{
$formMapper
->add('time', 'date', array('label' => 'Datum'))
;
}
El problema en mi formulario es cuando trato de agregar un momento (fecha) a mi sesión y aparece el siguiente error:
FatalErrorException: Error: Llame a una función miembro getName () en nulo en /myproject/app/cache/dev/classes.php línea 9772
Entonces, puedo agregar una sesión pero cuando trato de agregar un momento a mi sesión obtengo el error ....
Cuando miro en el archivoclases.php en la regla 9771 y 9772 hay:
$childFormBuilder = $this->getChildFormBuilder($formBuilder, $elementId);
$fieldDescription = $admin->getFormFieldDescription($childFormBuilder->getName());
los$childFormBuilder esnulo.
Cuando miro esa función, obtengo esto:
public function getChildFormBuilder(FormBuilder $formBuilder, $elementId)
{
foreach (new FormBuilderIterator($formBuilder) as $name => $formBuilder) {
if ($name == $elementId) {
return $formBuilder;
}
}
return;
}
Cuando hago un var_dump de $ name y $ elementId así:
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 $formBuilder;
}
}
die;
return;
}
Y presione el botón Agregar nuevo como en la siguiente imagen:
Entonces consigo esta salida:
name: s56cda71d2daa0_name
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_description
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_materials
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_numberOfParticipants
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_numberOfDays
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_price
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_priceKmo
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_location
elementId: s56cda71d2daa0_session_0_moment
name: s56cda71d2daa0_session
elementId: s56cda71d2daa0_session_0_moment
En todas mis entidades tengo una función __toString. Un ejemplo en mi entidad de curso:
public function __toString()
{
if(!is_null($this->name))
{
return $this->name;
}
else{
return "";
}
}
Cual podría ser el problema aquí? Estoy realmente atrapado con esto. También he publicado unproblema en el repositorio de Github de Sonata Admin pero no hay respuestas ...

ACTUALIZAR:
He agregado algunos var_dumps a mi funcióngetChildFormBuilder Me gusta esto:
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;
}

ACTUALIZACIÓN 2:
Cambié el requisito en mi composer.json a "sonata-project / admin-bundle": "^2.4@dev" y lo actualicé con composer. Pero ahora recibo este error:
ContextErrorException: Advertencia: desplazamiento de cadena ilegal 'admin' en la línea app / cache / dev / classes.php 10482
El error está en esta función:
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;
}
Los errores en línea:if (''!= $item['admin']) { .
En miconfig.yml Yo tengo:
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
Entonces creo que la funcióngetDashboardGroups Se llama allí.
ACTUALIZACIÓN 3:
En micomposer.json Ahora tengo lo siguiente:
"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"
¿Debo actualizarlos todos a^2.4@dev ?
