Hey all, I need to do some geospatial queries for my current project. Unfortunately, GAE doesn't allow multiple numerical comparisons in one query, so proximity queries based on latitude/longitude columns are out.
GeoModel to the rescue (http://code.google.com/p/geomodel/). By extending GeoModel, a GAE entity gains a location property that can be queried by distance/bounding box, etc. My question is how can I use this in a web2py model? Example code from http://code.google.com/p/geomodel/wiki/Usage : from geo.geomodel import GeoModel class MyEntity(GeoModel): foo = db.StringProperty() bar = db.IntegerProperty() some_entity = MyEntity(location=db.GeoPt(37, -122), foo='Hello', bar=5) ... some_entity.location = db.GeoPt(38, -122) some_entity.update_location() some_entity.put() resuts = MyEntity.proximity_fetch( MyEntity.all().filter('bar <', 10), # Rich query! geotypes.Point(39, -121), # Or db.GeoPt max_results=10, max_distance=80467) # Within 50 miles. -- You received this message because you are subscribed to the Google Groups "web2py-users" group.
