Django Rest Framework

Question

我一直在尝试上传多张图片，但我的API在图片列表中只占用了一张图片。可能是什么原因导致不拍摄所有图像？我做错了什么？

这是我的代码。 的 urls.py

    url(r'^api/', RentalList.as_view()),
    url(r'^api/upload/', FileUploadView.as_view()),
    url(r'^api/(?P<pk>[0-9]+)/$', RentalDetail.as_view()),

Models.py

class Rental(models.Model):
    email = models.CharField(max_length=120,blank=True, null=True)
    phoneNumber = models.PositiveIntegerField(blank=False,null=True,
        help_text=_("Phone number of contact person"))
    listingName =  models.CharField(_("Lisitng Name"), max_length=255, blank=False, null=True,
        help_text=_("Title of the rental space"))
    summary = models.TextField(max_length=500, blank=True, null= True,
        help_text=_("Description of the rental space"))
    property = models.CharField(_("Property type"),max_length=10,null=True)
    price = models.PositiveIntegerField(blank=False,null=True,
        help_text=_("Rental price of the space per month"))
    city =  models.CharField(_("City"), max_length=255, blank=False, null=True,
        help_text=_("City of the rental space"))
    place =  models.CharField(_("Place"), max_length=255, blank=False, null=True,
        help_text=_("Place of the rental space"))
    phone_image = models.CharField(max_length=2048,blank=True,null=True,
        help_text=_("image form of the phone number"))
    image = models.FileField(upload_to='upload/',null=True,blank=True)

Views.py

class RentalList(generics.ListCreateAPIView):
    serializer_class = RentalSerializer
    queryset = Rental.objects.all()
    def get(self,request,format=None):
        rental = self.get_queryset()
        serializer_rental = RentalSerializer(rental,many=True)

    def post(self, request, format=None):
        uploaded_file = request.FILES['image']
        print('up_file is',uploaded_file)
        filename = '/media/upload'
        with open(filename, 'wb+') as destination:
            for chunk in uploaded_file.chunks():

                destination.write(chunk)
                destination.close()

    submitRent: function(e) {
      // want to store the data so that when user reverts back to this form the data should be in same previous state 
      var req = request.post('http://localhost:8000/api/upload/');
      var image = [];
      image = new FormData();
      var that = this;
      var index;
      for (index = 0; index < that.state.files.length; ++index) {
          console.log(that.state.files[index]);
          image.append('image',that.state.files[index]);
      }
      req.send(image);
      console.log('req is',req);
      req.end((err, res) => {
        if (err) {
          console.log('error', err);
        } else {
          console.log('success', res);

        }
      });
    }   
});

我发布了所有代码，认为可能很容易跟踪错误。

我是否需要为图像创建ManyToMany字段？
