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"
},
}
***********
],
