在api平台中验证嵌入式模型

Question

我有这个Order模型：

<?php

use Symfony\Component\Serializer\Annotation\Groups;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Serializer\Annotation\SerializedName;

我正在尝试使用嵌入式嵌套项目而不是项目IRI在单个发布请求中使用其项目创建订单。正如文档建议的那样，我在@Assert\Valid模型内为orderItems getter方法添加Order。但它不会验证post请求中的orderItem数据。

Answer 1

我可以解决。Valid约束仅是验证嵌入式模型本身，因此，如果您不提供嵌入式模型的密钥，或者只是设置一个空数组验证，则不会执行任何操作。因此，您需要为属性本身添加另一个验证。在这种情况下，因为我希望我的orderItems至少包含一项，所以我为此属性添加了Count验证约束，如下所示。

/**
 * @Assert\Count(
 *      min = "1",
 *      minMessage = "You must specify at least one OrderItem"
 * )
 * @Assert\Valid()
 */
public function getOrderItems()
{
    return $this->orderItems;
}

因此它强制请求将其包含在列表中的一个OrderItem中
