postgis

I need to use an existing PostGIS database from my Rails application. So far I am able to access the DB just fine, GeoRuby nicely converts the 'geom' column into a Point object.

What I am looking for is an easy way to execute ActiveRecord-like queries on those tables, e.g.

Poi.find_within_radius(...)

or similar spatial queries like distance calculations et. al.

I tried several combinations of geokit, accompanying rails plugins but I'm quite sure there must be something better out there in the ruby/rails universe. Any hints?
