我在 Symfony 4 上覆盖 Sonata Admin 的
editAction每次管理员更改内容格式化程序时，它都会更改，并且更改会保存在 mysql 中
我想将默认选择的选项设置为保存在 MySQL 中的选项。 例如，如果管理员将其更改为
rawhtmlrawhtml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);
}
这是我的 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($rawcontent);
仍然不采用默认选择值。 有没有办法强制它从 mysql 中获取真正的值作为“数据”？ 我找不到应该在哪里编辑表单以从对象中获取默认选定值。如果您能帮助我，我将非常高兴。我不熟悉 Sonata 捆绑包和管理表单。
我认为根本不需要修改editAction或控制器。
我想将默认选择的选项设置为保存在 MySQL 中的选项。
这是一个经典用例，用于将值从表单保存回模型并在下次编辑时显示它。
相反，你应该修改你的管理类
我不知道你的模型，但例如在你的管理员中
configureFormFields$formMapper->add('contentFormatter', 'choice', ['choices' => ['Text' => 'text', 'Raw HTML' => 'rawHtml']]);
因此，选择的格式为“显示值 => 来自实体的值”。
因此，如果实体中的值返回“rawHtml”，则表单将选择“Raw HTML”。如果这不起作用，则说明您的管理员配置有误。仔细检查实体对象返回的值。
