如何在django-rest框架中访问父模型中的子完整记录

我是django rest framework的新手。我正在尝试将子模型记录作为字段获取到父模型,以便所有刷新图像模型记录都可以在games_sports列表中使用。我已经发布了示例代码。

模特儿

class Refreshment(models.Model):
    title = models.CharField(max_length=200, unique=True)
    type = models.CharField(max_length=200)
    charges = models.DecimalField(max_digits=12, decimal_places=2, help_text="Charges per hour")


class RefreshmentImage(models.Model):
    refreshment = models.ForeignKey(Refreshment, on_delete=models.CASCADE)
    image = models.FileField(upload_to="refreshment_image/", null=True, blank=True)

序列化程序.py

class EntertainmentSerializer(serializers.ModelSerializer):
     class Meta:
          model = Refreshment
          fields = '__all__'

  class RefreshmentImageSerializer(serializers.ModelSerializer):
        refreshment = EntertainmentSerializer(read_only=True, many=True)
        class Meta:
              model = RefreshmentImage
              fields = '__all__'

VIEW

def all_games_sports(request):
   entertainment = Refreshment.objects.all()
   serialize = EntertainmentSerializer(instance=entertainment,many=True)
   serial = RefreshmentImageSerializer(instance=entertainment,many=True)
   main = {'status': True, 'code': CODE_SUCCESSFUL, 'msg': SUCCESS, 'games_sports': serialize.data,'image':serial.data}
   return HttpResponse(json.dumps(main), content_type='application/json')

我得到的是:

games_sports": [
    {
        "id": 1,
        "title": "yyy",
        "type": 1,
        "charges": "500.00",
    },
    {
        "id": 2,
        "title": "xxxxx",
        "type": "something",
        "charges": "501.00",
    }
     *******
    ],
 "image": [
    {
        "id": 1,
        "image": null,
        "date_created": "2019-03-03T08:16:15.538024+05:30"
    },
    **********
  ]

我希望是:

games_sports": [
{
    "id": 1,
    "title": "yyy",
    "type": 1,
    "charges": "500.00",
    "image": [
             {
             "id": 1,
              "image": image_path,
              "date_created": "2019-03-03T08:16:15.538024+05:30"
          },

}
