Asked over at SO, we’re trying to include an additional value in our responses that JS can use alongside the original response which is used as a geojson. Please see question for full context.
Someone pointed out responses can be adjusted in views.py, which makes total sense, except we’re using viewsets.py, as adapted from @pauloxnet’s great map tutorial. We thought we should try to override the MarkerViewSet(viewsets.ReadOnlyModelViewSet) response as discussed here, but retrieve() doesn’t seem to do anything. What we hoped might work:
class MarkerViewSet(viewsets.ReadOnlyModelViewSet):
bbox_filter_field = "location"
filter_backends = (filters.InBBoxFilter,)
queryset = Marker.objects.all()
serializer_class = MarkerSerializer
def retrieve(self, queryset, request, *args, **kwargs):
print("retrieve method was used") # not being printed
return({'new_value': "foo", 'geojson': queryset})
Are we going about this the right way? How can we just include another value that JS can access with something like newResponse.new_value and existing functionality can continue getting the same data via newResponse.geojson or similar?
Thanks for any help!
