【问题描述】：
这是我的想法和我的位置。请告诉我这是否是不好的做法！
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。
- 评论只有一位作者。
- 评论有一篇文章。
我创建了一个名为 reviewAction 的控制器，我将在其中构建一个评论表单，将其传递给一个评论视图，并将其嵌入到我的文章显示视图中。
这是我目前的控制器（它不工作）
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，是否建议在此处构建此表单？似乎我在文章控制器中的 Review 类型上工作了很多。不知道我还会在哪里建造它。
我收到此错误：
属性“review”和方法之一“getReview()”、“review()”、“isReview()”、“hasReview()”、“__get()”都不存在并且在类中具有公共访问权限“AppBundle\Entity\Article”。
所以我真的被困住了，如果任何人都可以提供任何东西，我将不胜感激。

这是我的文章/review.html.twig 文件
{% extends 'base.html.twig' %}
{% block body %}
<h1>Review Article</h1>
{{ form_start(form) }}
{{ form_widget(form) }}
<input type="submit" value="Create" />
{{ form_end(form) }}
<ul>
<li>
<a href="{{ path('article_index') }}">Back to the list</a>
</li>
</ul>
{% endblock %}
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！
【问题讨论】：
-
不应该是
reviews而不是review吗？尝试阅读错误消息。 -
嗯，@ShiraNai7 你可能正在做一些事情，但现在我对这一切如何运作感到非常困惑。我将其更改为 ->add('reviews') 并且错误消失了。我收到关于标题的错误，所以我将其更改为标题.... 不走运。有没有人可以解释我在这里做错了什么？以及在文章控制器中构建评论表单是否正确？感谢您的评论！
-
哦，我明白为什么“评论”起作用了……我的实体确实有评论属性。所以我还是很困。
-
我的错误来自您的 Twig 文件。您能否在此文件中显示相应的代码：
article/review.html.twig？ -
感谢@alvinbunk 的回复。我已经加入了。
