在Symfony中，如何构建评论表单（我具有“评论”实体）以从Article控制器显示？

Question

这是我的想法，我在哪里。 请告诉我这是否是不良做法！

我有3个实体：文章，作者，评论：

关系：

• 文章只有一位作者。
• 文章有很多评论。
• 作者有很多文章。
• 评论有一位作者。
• 评论有一篇文章。

我创建了一个名为reviewAction的控制器，在其中将构建一个审阅表单，将其传递给审阅视图，并将其嵌入到我的文章展示视图中。

到目前为止，这是我的控制器（无法正常工作）

public function reviewAction(Request $request, Article $article)
{

    $reviewForm = $this->createFormBuilder($article);
    $reviewForm->add('review')->add('title')
        ->add('author', AuthorType::class, array("label" => FALSE))
        ->add('rating', ChoiceType::class, array(
            'choices' => array('1' => '1', '2' => '2', '3' => '3', '4' => '4', '5' =>'5'),
            'expanded' => true,
            'multiple' => false
        ))
        ->getForm();

    if ($reviewForm->isSubmitted() && $reviewForm->isValid()) {
        $this->getDoctrine()->getManager()->flush();
        return $this->redirectToRoute('article_show', array('id' => $article->getId()));
    }

    return $this->render('article/review.html.twig', array(
        'form' => $reviewForm->createView(),
    ));
}

首先，建议在此处构建此表格吗？ 似乎我在Articles控制器中的“评论”类型上工作量很大。 不知道我还能在哪里建造它。

我收到此错误：

属性“ review”或方法“ getReview（）”，“ review（）”，“ isReview（）”，“ hasReview（）”，“ __ get（）”都不存在，并且在类“ AppBundle \\”中没有公共访问权限实体\\文章”。

所以我真的很受困扰，希望任何人都可以提供任何帮助。

这是我的article / review.html.twig文件

    <ul>
        <li>
            <a href="{{ path('article_index') }}">Back to the list</a>
        </li>
    </ul>

更新：此代码有效

$reviewForm = $this->createFormBuilder($review)
    ->add('review', ReviewType::class, array("label" => FALSE))
    ->setAction($this->generateUrl('fundraiser_review', array('id' =>$fundraiser->getId())))
    ->getForm();

谢谢！

Answer 1

因为您正在创建文章表单，并且如果您查看文章实体，那么您将拥有一个reviews数组集合，因此您需要像这样更改代码：

$reviewForm = $this->createFormBuilder($article);
$reviewForm->add('reviews')
    ->add('title')
    ->add('author', AuthorType::class, array("label" => FALSE))
    ->add('rating', ChoiceType::class, array(
        'choices' => array('1' => '1', '2' => '2', '3' => '3', '4' => '4', '5' =>'5'),
        'expanded' => true,
        'multiple' => false
    ))
    ->getForm();

我认为应该解决。 不确定100％，但是请尝试并告知我们。
