Im trying to get values from geoqueryset methods but they do not return values. I use spatialite 4.0.0 as db.


bounds = Feature.objects.filter(
print bounds.perimeter

<bound method GeoQuerySet.perimeter of [<Feature: 43>]>

other example:

bounds = Feature.objects.filter(
print bounds.geojson(bbox=True)

[<Feature: 43>]

other example:

bounds = Feature.objects.filter(
print bounds.geojson(bbox=True)

<bound method GeoQuerySet.area of [<Feature: 38>]>

As documented here:, envelope is adding an envelope property for each element in the queryset.

So I'm not sure exactly what you expected. But envelope() is not meant to return a special result, it only adds an attribute on result objects.

Seeing that envelope is currently untested, I'll commit a test soon.

Ok, I understand that the methods do not return values but something seems to be wrong anyway

bounds = Feature.objects.filter(

<bound method GeoQuerySet.geojson of [<Feature: 17>]>

With Spatialite 4.0.0 the area() method just not work:

bounds = Feature.objects.filter(

no such table: spatial_ref_sys

But the table spatial_ref_sys do exists in the db
