我有一个名为提交内容的实体类型。提交与 SurveyData 实体类型具有一对一关系。

SurveyData 实体实际上是一个映射的超类。它最终将有几十个用于存储来自不同调查数据的实体子类。

根据文档，我创建了一个自定义规范化器，它基于类型键处理非规范化：

  public function denormalize($data, string $type, string $format = null, array $context = [])
  {
    if ($type === 'App\Entity\SurveyData\SurveyData') {
      $class = 'App\Entity\SurveyData\\' . $data['type'];
      $context['resource_class'] = $class;
    }

    $context[self::ALREADY_CALLED] = true;

    return $this->denormalizer->denormalize($data, 'App\Entity\SurveyData\\' . $data['type'], $format, $context);
  }

有了这个，我可以完美地创建一个嵌入了SurveyData的新提交。下面是我发送给POST请求的JSON示例：

{
    "facility": "/api/facilities/1",
    "survey": "/api/surveys/monthly_totals",
    "dateDetail": "Q1 2020",
    "surveyData": {
      "type": "MonthlyTotals",
      "num_deliveries": 50,
      "num_cesarean": 30,
      "num_epidural_anesthesia": 15
    },
    "created": "2020-08-14T18:59:49.218Z",
    "updated": "2020-08-14T18:59:49.218Z",
    "user": "brian",
    "status": "complete"
}

但是，当我通过 GET 获取集合或单个提交实体时，API 平台返回的响应忽略了将 @id 属性添加到嵌入式调查响应中。我不确定这是否是因为它是一个不能为空的一对一，所以它在内部被跟踪：

{
            "@id": "/api/submissions/2",
            "@type": "Submission",
            "id": 2,
            "facility": "/api/facilities/1",
            "survey": "/api/surveys/monthly_totals",
            "dateDetail": "Q1 2020",
            "created": "2020-08-14T18:59:49+00:00",
            "updated": "2020-08-14T18:59:49+00:00",
            "user": "brian",
            "status": "complete",
            "surveyData": {
                "num_deliveries": 50,
                "num_cesarean": 30,
                "num_epidural_anesthesia": 15
            }
        }

真正的问题是PUT和PATCH请求失败。

对于< code>PATCH请求，我可以更新父提交实体中的字段。但是，如果我发送以下请求，Submission和SurveyData实体将从数据库中删除，并且我会从API中得到以下错误:

“实体应用\\实体\\Submission@000000002116ebc30000000012ca4827不受管理。如果实体从数据库中获取或通过 EntityManager#persist 注册为新实体，则对其进行管理“，

整个反应的要点包括一个痕迹：https://gist.github.com/brianV/c32661186c91b49b013017dde77d5d4a

下面是一个触发错误的< code>PATCH请求的示例:

{
    "user": "brian",
    "surveyData": {
        "type": "MonthlyTotals",
        "num_deliveries": 100
    }
}

每个PUT请求也会发生这种情况(其中我包括了整个替换提交实体)。

简单的Symfony

根据注释请求，以下是提交实体注释：
