Symfony 4 覆盖奏鸣曲管理 CRUD 控制器

Question

我在 Symfony 4 上覆盖 Sonata Admin 的 editAction 时遇到问题。我的问题是我有这个编辑 posts 的界面，你可以看到这两张图片：

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

我想将默认选择的选项设置为 MySQL 中保存的选项。例如，如果管理员将其更改为 rawhtml，下次他想编辑此 post 时，他应该会发现默认选择的 rawhtml（不是图片中的文本）。

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);
}

这是我的 PostAdmin 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);

它仍然不采用默认选择值。无论如何强制它从 mysql 中获取真实值作为 'data' ？我找不到应该在哪里编辑表单以从对象中获取默认的选定值。如果你能帮我解决这个问题，我将非常高兴。我不熟悉奏鸣曲包和管理表单。

我认为根本不需要修改editAction 或控制器。

I want to make the default selected option the one saved in MySQL.

这是一个 classic 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，您应该修改您的管理员 class

我不知道你的型号，但例如在你的管理员 configureFormFields 方法中：

$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，如果您的实体值 returns 'rawHtml'，则表单将 select "Raw HTML"。如果这不起作用，则您的管理员配置有误。仔细检查实体对象的值 returns。
