Question

我要使用JSON发送图像数组，如下所示：

{"id":1,"timeIntervel":4,"images":["http://127.0.0.1:8000/images/i1.jpg","http://127.0.0.1:8000/images/i2.jpg","http://127.0.0.1:8000/images/i3.jpg","http://127.0.0.1:8000/images/i4.jpg","http://127.0.0.1:8000/images/i5.jpg"]}

我用外键对模型进行了尝试。但未能获得上述答复。

model.py

class slidesModel(models.Model):
    images = models.ImageField(upload_to='')
    def __str__(self):
        return str(self.images.name)

class slideImageArrayModel(models.Model):
    timeIntervel=models.IntegerField()
    images = models.ForeignKey(slidesModel, on_delete = models.CASCADE)
    def __str__(self):
        return str(self.id)

serializer.py

class slideSerializer(serializers.ModelSerializer):
    class Meta:
        model = slidesModel
        fields='__all__'

class slideImgArraySerializer(serializers.ModelSerializer):
    class Meta:
        model = slideImageArrayModel
        fields='__all__'
        depth = 1

views.py

class slidesViewSet(viewsets.ViewSet):
    def retrieve(self, request, pk=None):
        queryset = slideImageArrayModel.objects.all()
        user = get_object_or_404(queryset, pk=1) #it will always sends the first object
        serializer = slideImgArraySerializer(user)
        return Response(serializer.data)

我现有的输出需要一些修改才能实现实际输出：

{
    "id": 1,
    "timeIntervel": 4,
    "images": {
        "id": 8,
        "images": "/images/b1.jpg"
    }
}

我正在localhost中对此进行测试，并且未显示完整的url。我已经在设置和urls.py中包含了MEDIA_ROOT网址

使用DRF将图像数组作为JSON响应发送
