Symfony 4 覆盖 Sonata Admin CRUD 控制器

Question

在 Symfony 4 上覆盖 Sonata Admin 的 editAction 时遇到问题。 我的问题是我有这个用于编辑帖子的界面，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

我想让默认选择的选项保存在 MySQL 中。 例如，如果管理员将其更改为rawhtml，下次当他要编辑此帖子时，他应该会找到默认选中的rawhtml（不是图片中的文字）。

这是奏鸣曲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);

它仍然不采用默认选择值。 反正有没有强迫它从mysql中获取真正的价值作为“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。如果你能帮我解决这个问题，我会很高兴的。我不熟悉 Sonata 捆绑包和管理表单。

Answer 1

我认为根本不需要修改editAction或控制器。

我想让默认选择的选项保存在 MySQL 中。

这是将值从表单保存回模型并在下次编辑时显示的经典用例。

你应该修改你的管理类

我不知道您的模型，但例如在您的管理员configureFormFields 方法中：

$formMapper->add('contentFormatter', 'choice', ['choices' => ['Text' => 'text', 'Raw HTML' => 'rawHtml']]);

所以选择的格式为 Display Value => Value from the entity。

因此，如果您的实体值返回“rawHtml”，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错误。仔细检查您的实体对象返回的值。
