当我发送数据抛出PUT请求时，此id无法在经过验证的数据中获得此id。 例如PUT请求的正文：

{
  "slug": "string","company_id": 1,"api_secret": "string","merchant_url_list": [
    { 
      "id": 1
      "merchant_url_type_id": 1,"url": "string"
    }
  ]
}

但是在validated_data {'slug': 'string','company': <Company: Company object (1)>,'api_secret': 'string','merchanturl_set': [OrderedDict([('merchant_url_type',<MerchantUrlType: Бот (None)>),('url','string')])]}中 没有id。我如何获取ID？

class MerchantUrlSerializer(IdmodelSerializer):
    merchant = serializers.PrimaryKeyRelatedField(required=False,read_only=True)

    class Meta:
        model = MerchantUrl
        fields = ('id','merchant_url_type','merchant','url')


class MerchantSerializer(nestedSerializerMixin,IdmodelSerializer):
    merchant_url_list = MerchantUrlSerializer(source='merchanturl_set',many=True)

    class Meta:
        model = Merchant
        fields = ('id','slug','company','api_secret','merchant_url_list')

{
  "slug": "string","company_id": 0,"merchant_url_list": [
    {
      "merchant_url_type_id": 0,"url": "string"
    }
  ]
}
