I was trying to make an API using REST Framework for uploading a file to the server and my codes are below.

If you have any other easy method to do the same please post your code.

models.py

from django.db import models# Create your models here.class FileUploader(models.Model):file = models.FileField()name = models.CharField(max_length=100) #name is filename without extensionversion = models.IntegerField(default=0)upload_date = models.DateTimeField(auto_now=True, db_index=True)owner = models.ForeignKey('auth.User', related_name='uploaded_files')size = models.IntegerField(default=0)def __str__(self):return self.name

serializers.py

class FileUploaderSerializer(serializers.ModelSerializer):class Meta:model=FileUploaderfields='__all__'read_only_fields = '__all__'def validate(self, validated_data):validated_data['owner'] = self.context['request'].uservalidated_data['name'] = os.path.splitext(validated_data['file'].name)[0]validated_data['size'] = validated_data['file'].sizereturn validated_datadef create(self,validated_data):return FileUploader.objects.create(**validated_data)

views.py

class FileUploaderViewSet(viewsets.ModelViewSet):serializer_class = FileUploaderSerializerparser_classes=(MultiPartParser,FormParser)def get_queryset(self,request, *args, **kwargs):qs = super(FileUploaderViewSet, self).get_queryset(self,request, *args, **kwargs)qs = qs.filter(owner=self.request.user)return qs

urls.py

from django.conf.urls import url
from django.conf.urls import url,include
from django.contrib import admin
from rest_framework import routers
from rest_framework.authtoken.views import obtain_auth_token
from rest_framework.urlpatterns import format_suffix_patterns
from webapp import views
from webapp.views import(UserCreateAPIView,UserLoginAPIView,FileUploaderViewSet,)router = routers.DefaultRouter()
router.register(r'upload', views.FileUploaderViewSet,base_name='file-view')urlpatterns = [url(r'^admin/', admin.site.urls),url(r'^', include(router.urls)),#url(r'^upload/$',FileUploaderViewSet.as_view()),]

My requirement is that i need to upload a file to the server and the details of the uploaded file is to be shown.

This is the error i am getting!

get_queryset only requires self as a parameter.

Simply remove the other args.
