I would like a user to send a GET request to my Django REST API:
127.0.0.1:8000/model/?radius=5&longitude=50&latitude=55.1214
with his longitude/latitude and radius, passed in parameters, and get the queryset using GeoDjango.
For example, currently I have:
class ModelViewSet(viewsets.ModelViewSet):
queryset = Model.objects.all()
And what I ideally want is:
class ModelViewSet(viewsets.ModelViewSet):
radius = request.data['radius']
location = Point(request.data['longitude'],request.data['latitude']
# filter results by distance using geodjango
queryset = Model.objects.filer(location__distance_lte=(location, D(m=distance))).distance(location).order_by('distance')
Now a couple of immediate errors:
1) request is not defined - should I use api_view, i.e. the function based view for this?
2) DRF page says that request.data is for POST, PUT and PATCH methods only. How can send parameters with GET?
You can override get_queryset method for that purpose. As for query string parameters, you are right, request.data holds POST data, you can get query string params through request.query_params
def get_queryset(self):
longitude = self.request.query_params.get('longitude')
latitude= self.request.query_params.get('latitude')
radius = self.request.query_params.get('radius')
location = Point(longitude, latitude)
queryset = Model.objects.filter(location__distance_lte=(location, D(m=distance))).distance(location).order_by('distance')
return queryset
I had the same problem, to solve it you can get parameters from url with self.request.parser_context.get('kwargs') under the get_queryset method.
