我有三个实体：用户，评论，文章。用户可以发表评论/文章。
在我的文章控制器中，我有一个名为commentAction的方法，它应该返回注释表单。我在文章显示模板中调用此控制器。它有效，但当我尝试验证表单时会出现问题。
我想将用户返回到文章显示页面，并显示评论表单错误。
两个问题：表单将我们带到commentAction而不是回到showAction。另外，由于某种原因，我无法获得验证错误。
我已经合并了一个货运代理（无论如何它似乎都不正常）。有人能告诉我正确的方法吗？
非常感谢！
P.S。我是Symfon的新手所以如果你能提醒我，如果我违反了任何最佳做法我会很感激你，如果你让我知道:)。

将您的show动作放在createFormBuilder中的 - ＆gt; setAction（）中，而不是像您当前拥有的那样进行评论操作。
->setAction($this->generateUrl('article_show', array('id' =>$article->getId())))
您需要在show动作中处理解析表单。我总是建议使用错误冒泡来显示页面顶部的所有错误。在您的createFormBuilder中，只需修改您的添加：
>add('comment', CommentType::class, array("label" => false, 'error_bubbling' => true))
然后在您的Twig中，将其放在您的表单上方：
{% if form_errors(form)|length > 10 %}
<div class="col-md-10 col-md-offset-1">
<div class="alert alert-danger fade-in">
{{ form_errors(form) }}
</div>
</div>
{% endif %}

我假设您可以在文章中添加许多评论。然后，您在这些实体之间拥有一对多关系。这必须在使用注释的实体声明中定义。有关详细信息，请参阅此文章：http://symfony.com/doc/current/doctrine/associations.html
使用此定义，您可以为实体Comment创建单独的表单类型。在实体文章的表单类型中，您将字段“comment”定义为 CollectionType 。 Symfony使用实体Comment的表单类型在实体Article中呈现字段注释。有关详细信息，请参阅此文章：https://symfony.com/doc/current/form/form_collections.html
