Symfony2 CollectionType验证

Question

仅当表单上存在CollectionType的输入时，才能如何在AdMenuLinkType表单中验证CollectionType。

例如：当我在浏览器中打开添加表单时，我可以创建没有路由参数的链接。 当我单击按钮“添加参数”时-javascript从AdMenuRouteDataType表单呈现2个字段。 这两个字段必须是必填字段，不能为空。 如果我使用这些空字段提交表单-我需要获取错误。 如果我不单击“添加参数”按钮，则不会呈现集合输入字段，并且我可以提交没有此数据和错误的表单。 我该怎么做？

我有实体：AdMenuRouteData

<?php

    private $id;

    private $value;

    public function getId()
    {
        return $this->id;
    }

    /**

    public function getLink()
    {
        return $this->link;
    }

    /**

    public function setLink($link)
    {
        $this->link = $link;
    }

    public function setValue($value)
    {
        $this->value = $value;

        return $this;
    }

    /**

我将表单类型用于AdMenuLink：

Answer 1

我使用断言Valid（）来完成此任务，并且可以正常工作。

/**
     * @ORM\OneToMany(targetEntity="AdBackendBundle\Entity\AdMenuRouteData", mappedBy="link", cascade={"persist"})
     * @Assert\Valid()
     */
    private $routeData;
