Sorting support

[miki725]

Having form validate all of the query data, might as well add ordering support.

I'm using this mixin for ordering.

class QueryOrderableViewSetMixin(object):

    def get_queryset(self):
        queryset = super(QueryOrderableViewSetMixin, self).get_queryset()
        try:
            order_by = self.request.query_params['order_by']
            return queryset.order_by(*order_by.split(','))
        except KeyError:
            return queryset

Is there a particular reason that DRF's built in ordering filter_backend fails in conjunction with using Django URL filter?

Here is my class-based view:

class OpportunityListCreate(generics.ListCreateAPIView):
    """
    Class-based view supporting get and post request to list all Opportunity or create a Opportunity, if permitted.

    Attributes:
        authentication_class (tuple): Uses JWT authentication.
        permission_classes (tuple): Requires authentication.
        queryset (method_call): Method returning list for use in serializing results for response.
        serializer_class (cls): Serializer class providing serialized UserProfile for response.
    """
    authentication_classes = (JSONWebTokenAuthentication,)
    permission_classes = (IsAuthenticated,)
    queryset = Opportunity.objects.all()
    filter_backends = (DjangoFilterBackend,
                       OpportunityFilterBackend, filters.OrderingFilter,)
    ordering_fields = ('created_date',)
    filter_fields = ['tags', 'created_date']
    serializer_class = OpportunitySerializer

I am using DjangoFilterBackend, my own OpportunityFilterBackend to restrict querysets based on the user type, and filters.OrderingFilter to provide ordering support. However, ordering does not seem to work at all.

Where does one employ the mixin used above?

I'm really interested in this feature as well.
