Django Rest Framework：嵌套序列化器不工作

Question

我几乎已经尝试了所有方法，但还是无法达到目的

model.py 文件


class RecievingImages(models.Model):
     """Original and Masked Images"""
    ....
    name                        = models.CharField(max_length = 100, unique = True, primary_key=True)
    area                        = models.IntegerField()
    number                      = models.IntegerField()
    agency_name                 = models.CharField(max_length=100, default='general')
    rawImage                    = models.ImageField(upload_to=imageNameForRawImage,)
    ...

class UpdationImages(models.Model):
    """ Update Image wrt name"""
    ....
    name                        = models.ForeignKey(RecievingImages, on_delete=models.PROTECT, related_name='updated')
    updated_image               = models.ImageField(upload_to=UpdatedImageFolder,)
    updated_image_url           = models.TextField(default='None')
   ....

serializer.py

class UpdatedImageSerializer(serializers.ModelSerializer):
  class Meta:
    model = UpdationImages
    fields = ('name', 'updated_image', 'updated_image_url')

class RecievingImagesSerializer(serializers.ModelSerializer):
  updated = UpdatedImageSerializer(many= True, read_only=True)
  class Meta:
    model = RecievingImages
    fields = ('updated','name','area','number','agency_name', rawImage)

我在模型中使用了 related_name 并且还遵循文档以及 many = True

但是还是在serializer.dataupdated不显示

views.py

class MappingSinglePhoto(APIView):
    """ Mapping Single Image """
    def post(self, request):
        try:
            data = request.data
            # import pdb; pdb.set_trace()
            name_of_image = data['name']
            mapped_images_qs = UpdationImages.objects.select_related('name').filter(name = name_of_image)
            for image in mapped_images_qs:
                serializer = RecievingImagesSerializer(instance = image)
                pdb.set_trace()
                serializer.data
            # return Response(serializer.data)
        except Exception as e:
            print(e)

注意如果我使用 depth=1 那么它工作正常，但我不是在寻找深度显示的所有字段。

感谢和问候

查询有问题views.py

class MappingSinglePhoto(APIView):
    """ Mapping Single Image """
    def post(self, request):
        try:
            data = request.data
            # import pdb; pdb.set_trace()
            name_of_image = data['name']
            mapped_images_qs = RecievingImages.objects.filter(name = name_of_image)
            for image in mapped_images_qs:
                serializer = RecievingImagesSerializer(instance = image)
                pdb.set_trace()
                serializer.data
            # return Response(serializer.data)
        except Exception as e:
            print(e)
