Hard time figuring out how to use DistanceToPointFilter

[Hesam Dadafarin]

Hi All,

We are very new to whole django GIS and we have hard time implement our filter for a model viewset:

class GeoModelViewSet(viewsets.ModelViewSet):
   queryset = Geo.objects.all()
   serializer_class = GeoSerializerSmall
   distance_filter_field = 'location'
   filter_backend = (DistanceToPointFilter, )

def list(self, request):
    queryset = Geo.objects.all()
    queryset = GeoFilter(request.GET, queryset=queryset)
    serializer = NDTSerializerSmall(queryset, many=True)
    return Response(serializer.data)

Although the example on the documentation look very simple, but we don't have any clue how we should modify our view or seriallizer to get this working. We even checked the filter.py on Github and it made sense to us how you have imeplemented the distance filter but we don't know the exact syntax of applying the filter to our data.

Thanks for you help.

Hi Hesam,

since this was a contribution to DRF-gis, I do not know a lot more than you do.

I can suggest you to look at the official DRF documentation for filter and filtersets and study the test project in the DRF-gis repository more closely.

Hi Hesam,

you may ask on stackoverflow.com and use the new django-rest-framework-gis tag. This should help you more than what I could.
