是否可以在 symfony 5 中自定义违反约束错误渲染？

Question

我是 symfony 的初学者，我想使用框架工具从头开始创建注册表单。 因此，无需使用“make:register ...”命令行。

我已经使用注释语法实现了一个表单和约束。 但是，当我想显示消息错误时，它会呈现：注册表错误视图示例

我想要的是在我的 controller 中获取所有约束错误，并将它们呈现在引导危险警报中。 尽管查看了文档，但我无法解决我的问题。 因此，你能给出一些解释吗？ 这是我的代码：

实体：

 * @ORM\Table(name="users")

Controller：

class UserController extends AbstractController
{
    /**

     */
    private $em;


    public function __construct(EntityManagerInterface $em)
    {
        $this->em = $em;
    }

    /**
     * @Route("/signup", name="User/signup.html.twig")
     * @param Request $r
     * @param UserPasswordEncoderInterface $p
     * @return Response
     */
    public function signUp(Request $r, UserPasswordEncoderInterface $p): Response
    {
        $user = new Users();
        $form = $this->createForm(UsersRegistrationType::class, $user);
        $form->handleRequest($r);
        if ($form->isSubmitted() && $form->isValid())
        {
            $password = $p->encodePassword($user, $user->getPassword());
            $user->setPassword($password);
            $this->em->persist($user);
            $this->em->flush();
            return $this->redirectToRoute('home.html.twig');
        }
        return $this->render('User/signup.html.twig', ["form" => $form->createView()]);
    }
}

看法：

{% extends 'base.html.twig' %}

{% block title %}Création d'un nouveau compte Avanza{% endblock %}

{% block body %}
    {{ form_start(form,  {'attr': {
        'style': 'width: 30%;
        margin: auto;
        margin-top: 5%;
        border-color: #307424;'}}) }}
    <h4 class="text-center">Créer un compte</h4>
    <div class="container">
        <div class="row">
                {{ form_row(form.name) }}
        </div>
        <div class="row">
                {{ form_row(form.firstname) }}
        </div>
        <div class="row">
                {{ form_row(form.email) }}
        </div>
        <div class="row">
                {{ form_row(form.phone) }}

        </div>
        <div class="row">
            <div class="col">
                {{ form_row(form.password) }}
            </div>
        </div>
        <div class="row"style="margin-top: 5%;">

如果您想更改表单错误的显示方式，您可能需要创建自己的表单主题来扩展您当前的主题（可能是引导程序主题之一）。

您正在使用{{ form_row() }} ，它还将呈现一个form_label-block ，其中包括呈现一个form_errors-block 。

您可能想要覆盖{% block form_label %}以便它不再呈现错误，然后您覆盖{% block form_errors %}以呈现警报。 然后，您可以在要显示警报的表单中手动使用{{ form_errors(form) }} 。

例如，form_errors-block 可能看起来像这样：

{% block form_errors -%}
    {%- if errors|length > 0 -%}
        {%- for error in errors -%}
            <div class="alert alert-danger">
                <strong>{{ 'Error'|trans({}, 'validators') }}</strong>
                {{ error.message }}
                <button type="button" class="close" data-dismiss="alert" aria-label="Close">
                    <span aria-hidden="true">&times;</span>
                </button>
            </div>
        {%- endfor -%}
    {%- endif %}
{%- endblock form_errors %}
