我在覆盖Symfony 4上的Sonata Admin的editAction时遇到问题。
我的问题是，我有一个用于编辑帖子的界面，如您所见，这是两个图片：
Everytime The admin change the content formatter it get changed and the changes get saved in mysql
but when you try to edit the post again the admin get always 'text' selected by default
我想使默认选择的选项成为保存在MySQL中的选项。
例如，如果管理员将其更改为rawhtml，那么下次他要编辑此帖子时，他应该找到默认情况下选中的rawhtml（而不是图像中的文本）。
这是Sonata editAction方法：
public function editAction($id = null)
{
$request = $this->getRequest();
// the key used to lookup the template
$templateKey = 'edit';
$id = $request->get($this->admin->getIdParameter());
$existingObject = $this->admin->getObject($id);
if (!$existingObject) {
throw $this->createNotFoundException(sprintf('unable to find the object with id: %s', $id));
}
$this->checkParentChildAssociation($request, $existingObject);
$this->admin->checkAccess('edit', $existingObject);
$preResponse = $this->preEdit($request, $existingObject);
if (null !== $preResponse) {
return $preResponse;
}
$this->admin->setSubject($existingObject);
$objectId = $this->admin->getNormalizedIdentifier($existingObject);
/** @var $form Form */
$form = $this->admin->getForm();
$form->setData($existingObject);
$form->handleRequest($request);
if ($form->isSubmitted()) {
$isFormValid = $form->isValid();
// persist if the form was valid and if in preview mode the preview was approved
if ($isFormValid && (!$this->isInPreviewMode() || $this->isPreviewApproved())) {
$submittedObject = $form->getData();
$this->admin->setSubject($submittedObject);
try {
$existingObject = $this->admin->update($submittedObject);
if ($this->isXmlHttpRequest()) {
return $this->renderJson([
'result' => 'ok',
'objectId' => $objectId,
'objectName' => $this->escapeHtml($this->admin->toString($existingObject)),
], 200, []);
}
$this->addFlash(
'sonata_flash_success',
$this->trans(
'flash_edit_success',
['%name%' => $this->escapeHtml($this->admin->toString($existingObject))],
'SonataAdminBundle'
)
);
// redirect to edit mode
return $this->redirectTo($existingObject);
} catch (ModelManagerException $e) {
$this->handleModelManagerException($e);
$isFormValid = false;
} catch (LockException $e) {
$this->addFlash('sonata_flash_error', $this->trans('flash_lock_error', [
'%name%' => $this->escapeHtml($this->admin->toString($existingObject)),
'%link_start%' => '<a href="'.$this->admin->generateObjectUrl('edit', $existingObject).'">',
'%link_end%' => '</a>',
], 'SonataAdminBundle'));
}
}
// show an error message if the form failed validation
if (!$isFormValid) {
if (!$this->isXmlHttpRequest()) {
$this->addFlash(
'sonata_flash_error',
$this->trans(
'flash_edit_error',
['%name%' => $this->escapeHtml($this->admin->toString($existingObject))],
'SonataAdminBundle'
)
);
}
} elseif ($this->isPreviewRequested()) {
// enable the preview template if the form was valid and preview was requested
$templateKey = 'preview';
$this->admin->getShow();
}
}
$formView = $form->createView();
// set the theme for the current Admin Form
$this->setFormTheme($formView, $this->admin->getFormTheme());
// NEXT_MAJOR: Remove this line and use commented line below it instead
$template = $this->admin->getTemplate($templateKey);
// $template = $this->templateRegistry->getTemplate($templateKey);
return $this->renderWithExtraParams($template, [
'action' => 'edit',
'form' => $formView,
'object' => $existingObject,
'objectId' => $objectId,
], null);
}
这是我用于PostAdmin的configureFormFields方法：
$isHorizontal = 'horizontal' == $this->getConfigurationPool()->getOption('form_type');
$formMapper
->with('group_post', [
'class' => 'col-md-8',
])
->add('author', ModelListType::class)
->add('title')
->add('abstract', TextareaType::class, [
'attr' => ['rows' => 5],
])
->add('content', FormatterType::class, [
'event_dispatcher' => $formMapper->getFormBuilder()->getEventDispatcher(),
'format_field' => 'contentFormatter',
'source_field' => 'rawContent',
'source_field_options' => [
'horizontal_input_wrapper_class' => $isHorizontal ? 'col-lg-12' : '',
'attr' => ['class' => $isHorizontal ? 'span10 col-sm-10 col-md-10' : '', 'rows' => 20],
],
'ckeditor_context' => 'news',
'target_field' => 'content',
'listener' => true,
])
->end()
->with('group_status', [
'class' => 'col-md-4',
])
->add('enabled', CheckboxType::class, ['required' => false])
->add('image', ModelListType::class, ['required' => false], [
'link_parameters' => [
'context' => 'news',
'hide_context' => true,
],
])
->add('publicationDateStart', DateTimePickerType::class, [
'dp_side_by_side' => true,
])
->add('commentsCloseAt', DateTimePickerType::class, [
'dp_side_by_side' => true,
'required' => false,
])
->add('commentsEnabled', CheckboxType::class, [
'required' => false,
])
->add('commentsDefaultStatus', CommentStatusType::class, [
'expanded' => true,
])
->end()
->with('group_classification', [
'class' => 'col-md-4',
])
->add('tags', ModelAutocompleteType::class, [
'property' => 'name',
'multiple' => 'true',
'required' => false,
])
->add('collection', ModelListType::class, [
'required' => false,
])->end();
$options = $formMapper->get('content')->get('contentFormatter')->getOptions();
$options = array_merge($options,array('choices'=>array('markdown'=>'markdown','text'=>'text','rawhtml'=>'rawhtml','richhtml'=>'richhtml')));
$rawcontent = $formMapper->get('content')->get('rawContent');
$formMapper->get('content')->remove('contentFormatter')->remove('rawContent')->add('contentFormatter',ChoiceType::class,$options)->add($rawcontent);
it仍然不采用默认的选定值。 无论如何，有没有强迫它把mysql的真实值当作'数据'？ 我找不到应该在哪里编辑表单以从对象获取默认选定值的地方。请您帮助我，我将非常高兴。我对Sonata捆绑包和表单管理不熟悉。

我认为根本不需要修改editAction或控制器。
我想使默认选择的选项成为保存在MySQL中的选项。
这是一个经典的用例，用于将值从表单保存回模型并在下次编辑时显示。
相反，您应该修改管理员类
我不知道您的型号，但是例如您的管理员configureFormFields方法中的
$formMapper->add('contentFormatter', 'choice', ['choices' => ['Text' => 'text', 'Raw HTML' => 'rawHtml']]);
因此，选择的格式为“显示值=>实体的值”。
因此，如果您来自实体的值返回“ rawHtml”，则表单将选择“原始HTML”。如果这不起作用，则说明您的管理员配置有误。仔细检查从您的实体对象返回什么值。
