Unfortunately the built in Django JSON serialzer encodes GeoDjango GeometyrField as WKT text. This snippet extends django's serializer and adds support for GEOJson format.

Built in JSON serializer output:
[{"pk": 1, ... "geopoint": "POINT (-76.5060419999999937 44.2337040000000030)" ... }]

GeoJSON serializer ouput:
[{"pk": 1, ...  "geopoint": {"type": "Point", 
    "coordinates": [-76.503296000000006, 44.230956999999997],
    "__GEOSGeometry__": [
                "__init__",
