在Django rest框架中获取图像文件和字段

Question

我正在尝试通过 django restframe work 上传图片并返回自定义响应 views.py

class Imageuploadviewset(viewsets.ModelViewSet):
   queryset = UploadModel.objects.all()
   serializer_class = UploadSerializer
   def retrieve(self, request, *args, **kwargs):
    instance = self.get_object()
    serializer = self.get_serializer(instance)

    return Response({'something': 'serializer'})
   def list(self, request, *args, **kwargs):
    return Response({'Model': 'Skin Disease Diagnosis'})

models.py

class UploadModel(models.Model):
    name=models.CharField(max_length=50)
    image=models.ImageField('images/')

urls.py

router = DefaultRouter()
router.register(r'UploadModel', views.Imageuploadviewset)

urlpatterns = [
    path('',views.home,name='home'),
    path('api/', include(router.urls)),
]

Serializer.py

class UploadSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model=UploadModel
        fields='__all__'

询问如何使用name 和image 上传，在它们上运行一些函数并返回响应。我不知道如何获得这些。

Answer 1

我需要create 函数而不是retrieve 和list

def create(self, request):
      img=request.FILES['image']
      user=request.POST['name']
      pred=somefunction(ai,img)
      return Response({'user':user,'prediction':pred})
