comment Create a GEOSGeometry from a FeatureCollection in GeoDango
Django does not currently support deserialization of geojson data, as stated here docs.djangoproject.com/en/dev/ref/contrib/gis/serializers . So you will have to come up with a custom solution along the lines of what alex proposed.

comment GeoDjango and PostGIS distance query efficiency concerns
If you set up Django with a PostGIS backend, then GeoDjango does essentially create PostGIS queries for you through distance lookups, it also automatically creates spatial indexes on your tables for models with geographic fields. The lookups are thus almost as fast as PostGIS queries. See docs.djangoproject.com/en/1.9/ref/contrib/gis/db-api/…

comment geojson data not getting displayed on map (Openlayers) in Geodjango
The serializer should find the geometry field and use it to serialize, I dont know why you are getting null values in the results.

comment geojson data not getting displayed on map (Openlayers) in Geodjango
The print is not very useful like this, the goal was to see the geometries. Could you try for dat in PFT.objects.all()[:10]: print dat.geom?

comment geojson data not getting displayed on map (Openlayers) in Geodjango
I updated the answer, try removing the geometry_field argument. If you dont have data, it could mean that you have rows that don't have a geometry. Try also PFT.objects.filter(geom__isnull=False)[:10]. What does print [dat.geom for dat in PFT.objects.all()[:10]] return?

comment List of GDAL raster file extensions
I am not sure if I agree that file extensions are completely meaningless, but you are right that they are not a reliable way of determining file types.
