奏鸣曲管理员.如何将发布数据传递到另一个控制器

Question

我是Symfony的新手，所以请原谅我的无知。

我有一个父实体"文章"和子条目，如"页面"、"新闻"等。它们具有标题，日期等公共字段。

我为文章创建了初始表单(在 ArticleAdmin 类中(，可以选择子实体的标题和类型，并尝试调用子实体的 Admin 类并将 POST 数据传递给那里。但这不起作用，因为控制器中的createAction负责表单渲染及其处理，当我尝试在我的createAction((中覆盖它时，我收到错误"错误：调用私有方法Sonata\AdminBundle\Controller\CRUDController：：setFormTheme((">

这是我的代码：

文章管理员 - 父实体

<?php
namespace A26CMSContentBundleAdmin;
use SonataAdminBundleAdminAbstractAdmin;
use SonataAdminBundleShowShowMapper;
use SonataAdminBundleFormFormMapper;
use SonataAdminBundleDatagridListMapper;
use SonataAdminBundleDatagridDatagridMapper;
class ArticleAdmin extends AbstractAdmin
{
// Fields to be shown on create/edit forms
protected function configureFormFields(FormMapper $formMapper)
{
    $formMapper
        ->add('title', 'text', array(
            'label' => 'Title'
        ))
        ->add('slug', 'text', array(
            'label' => 'Slug'
        ))
        ->add('type', 'choice', array(
            'choices' => array(
                'Page'      => 'Text Page',
                'News'      => 'News'
            ),
        ));
}
protected function configureDatagridFilters(DatagridMapper $datagridMapper)
{
    $datagridMapper
        ->add('title');
}
protected function configureListFields(ListMapper $listMapper)
{
    $listMapper
        ->addIdentifier('title')
        ->add('is_publish');
}
protected function configureShowFields(ShowMapper $showMapper)
{
    $showMapper
        ->add('title');
}
}
?>

页面管理员 - 子实体

<?php
namespace A26CMSPagesBundleAdmin;
use SonataAdminBundleAdminAbstractAdmin;
use SonataAdminBundleShowShowMapper;
use SonataAdminBundleFormFormMapper;
use SonataAdminBundleDatagridListMapper;
use SonataAdminBundleDatagridDatagridMapper;
use IvoryCKEditorBundleFormTypeCKEditorType;
class PageAdmin extends AbstractAdmin
{
// Fields to be shown on create/edit forms
protected function configureFormFields(FormMapper $formMapper)
{
    $formMapper
        ->tab('Content')
            ->with('Content')
                ->add('title', 'text', array(
                    'label' => 'Title'
                ))
                ->add('content', CKEditorType::class, array(
                    'label'         => 'Content'
                ))
            ->end()
        ->end();
}
// Fields to be shown on filter forms
protected function configureDatagridFilters(DatagridMapper $datagridMapper)
{
    $datagridMapper
        ->add('title');
}
// Fields to be shown on lists
protected function configureListFields(ListMapper $listMapper)
{
    $listMapper
        ->addIdentifier('title');
}
// Fields to be shown on show action
protected function configureShowFields(ShowMapper $showMapper)
{
    $showMapper
        ->add('title');
}
}
?>

文章管理员控制器 - 我复制了 CRUDController 并替换了块

if ($form->isSubmitted((( {...}

<?php
namespace A26CMSContentBundleController;
use SonataAdminBundleControllerCRUDController as Controller;
class ArticleAdminController extends Controller
{
public function createAction()
{
    $request = $this->getRequest();
    // the key used to lookup the template
    $templateKey = 'edit';
    $this->admin->checkAccess('create');
    $class = new ReflectionClass($this->admin->hasActiveSubClass() ? $this->admin->getActiveSubClass() : $this->admin->getClass());
    if ($class->isAbstract()) {
        return $this->render(
            'SonataAdminBundle:CRUD:select_subclass.html.twig',
            array(
                'base_template' => $this->getBaseTemplate(),
                'admin' => $this->admin,
                'action' => 'create',
            ),
            null,
            $request
        );
    }
    $object = $this->admin->getNewInstance();
    $preResponse = $this->preCreate($request, $object);
    if ($preResponse !== null) {
        return $preResponse;
    }
    $this->admin->setSubject($object);
    /** @var $form SymfonyComponentFormForm */
    $form = $this->admin->getForm();
    $form->setData($object);
    $form->handleRequest($request);
    if ($form->isSubmitted()) {
        $response = $this->forward("A26CMSPagesBundle:PageAdmin:create", array('_sonata_admin' => $this->container->get('request')->get('_sonata_admin')));
        dump($response);
        die();
    }
    $formView = $form->createView();
    // set the theme for the current Admin Form
    $this->setFormTheme($formView, $this->admin->getFormTheme());
    return $this->render($this->admin->getTemplate($templateKey), array(
        'action' => 'create',
        'form' => $formView,
        'object' => $object,
    ), null);
}
}

请帮忙！也许可以用另一种方式实现？

提前感谢！！

Answer 1

你做$response的方式是正确的，但现在你需要在操作结束时返回它，否则转发将永远不会发生

Answer 2

关于你得到的错误，

相反：

$this->setFormTheme($formView, $this->admin->getFormTheme());

用：

$this->get('twig')->getExtension('form')->renderer->setTheme($formView, $this->admin->getFormTheme());

或：

$this->get('twig')->getExtension('SymfonyBridgeTwigExtensionFormExtension')->renderer->setTheme($formView, $this->admin->getFormTheme());
