Вложенные поля коллекции в Sonata Admin (2.3)

У меня возникают проблемы с созданием формы для создания курса. Это часть моей схемы базы данных, для которой я пытаюсь создать форму:

• Настройка SonataNewsBundle для обработки сообщений в сообщениях
• sonataNotificationBundle, электронные письма, которые хранятся в базе данных, но потребитель swiftmailer не запускается, и никакие электронные письма не отправляются
• Расширение пользовательского пакета Sonata и добавление новых полей
• Проблема с sonataIntlBundle - я не могу установить с композитором
• Как отобразить текущее изображение над полем загрузки в SonataAdminBundle?

Поэтому я пытаюсь 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

Таким образом, я могу добавить сеанс, но когда я пытаюсь добавить момент на мой сеанс, я получаю ошибку ….

Когда я смотрю в файле classes.php в правиле 9771 и 9772, есть:

 $childFormBuilder = $this->getChildFormBuilder($formBuilder, $elementId); $fieldDescription = $admin->getFormFieldDescription($childFormBuilder->getName()); 

$childFormBuilder имеет значение 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 $ 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», как показано 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 ""; } } 

Что может быть проблемой здесь? Я действительно застрял в этом. Я также опубликовал вопрос о реестре github для Sonata Admin, но нет ответов …

Moment Entity :

 <?php namespace Studyx\EnrolmentBundle\Entity; use Doctrine\ORM\Mapping as ORM; /** * Moment * * @ORM\Table(name="moment") * @ORM\Entity */ class Moment { /** * @var \DateTime * * @ORM\Column(name="time", type="datetime", nullable=false) */ private $time; /** * @var integer * * @ORM\Column(name="ID", type="integer") * @ORM\Id * @ORM\GeneratedValue(strategy="IDENTITY") */ private $id; /** * @var \Studyx\EnrolmentBundle\Entity\Session * * @ORM\ManyToOne(targetEntity="Studyx\EnrolmentBundle\Entity\Session") * @ORM\JoinColumns({ * @ORM\JoinColumn(name="session_ID", referencedColumnName="ID") * }) */ private $session; public function __toString() { if(!is_null($this->time)) { return $this->time; } else{ return ""; } } /** * Set time * * @param \DateTime $time * @return Moment */ public function setTime($time) { $this->time = $time; return $this; } /** * Get time * * @return \DateTime */ public function getTime() { return $this->time; } /** * Get id * * @return integer */ public function getId() { return $this->id; } /** * Set session * * @param \Studyx\EnrolmentBundle\Entity\Session $session * @return Moment */ public function setSession(\Studyx\EnrolmentBundle\Entity\Session $session = null) { $this->session = $session; return $this; } /** * Get session * * @return \Studyx\EnrolmentBundle\Entity\Session */ public function getSession() { return $this->session; } } 

ОБНОВИТЬ:

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; } 

В результате получается следующее:

ОБНОВЛЕНИЕ 2:

Я изменил требование в моем composer.json на «sonata-project / admin-bundle»: «^2.4@dev» и обновил композитор. Но теперь я получаю эту ошибку:

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 

Поэтому я думаю, что там называется функция getDashboardGroups .

ОБНОВЛЕНИЕ 3:

Должен ли я обновить их все до ^ ^2.4@dev ?

• пользовательское действие в SonataAdminBundle
