Error while initializing rest framework urls

I'm refactoring my REST API now. After using

instead of direct urls I can't launch my project. Where am I wrong?


TypeError: as_view() takes exactly 1 argument (3 given)

class Device(models.Model):

class Measure(models.Model):
device = models.ForeignKey(Device)

class PeriodAverage(models.Model):
measure = models.ForeignKey(Measure)

router = routers.DefaultRouter()
router.register(r'devices', views.DevicesList)
router.register(r'devices/{pk}/measures', views.MeasuresList, 'Measure')
router.register(r'measures/{pk}/averages', views.PeriodAveragesList, 'Average')

urlpatterns = [
url(r'^api/v1/', include(router.urls)),

class DevicesList(viewsets.ModelViewSet):
queryset = Device.objects.all()
serializer_class = serializers.DeviceSerializer

class MeasuresList(viewsets.ModelViewSet):
serializer_class = serializers.MeasureSerializer

def get_queryset(self):

class PeriodAveragesList(ListAPIView):
serializer_class = serializers.PeriodAverageSerializer

def get_queryset(self):

Routers work with ViewSets. Your PeriodAveragesList extends ListAPIView, which is a class based view, not a ViewSet.

If you still want to use a router for that view, see this answer for a workaround.
