The best way to search according to distance in ruby on rails

In ror, suppose I have a list of geo referenced data in my database (each record have latitude and longitude column) what is the best way to implement search according-to-distance function?

I am aware of geokit for ruby. But I am looking for other suggestions. If it is platform dependent, I plan to use heroku as deployment platform.

Use the gem Geocoder.

As specified in documentation -

Geocoder is a complete geocoding solution for Ruby. With Rails it adds geocoding (by street or IP address), reverse geocoding (find street address based on given coordinates), and distance queries. It's as simple as calling geocode on your objects, and then using a scope like Venue.near("Billings, MT").

With geocoded objects you can do things like this:

if obj.geocoded?
  obj.nearbys(30)                      # other objects within 30 miles
  obj.distance_from([40.714,-100.234]) # distance from arbitrary point to object
  obj.bearing_to("Paris, France")      # direction from object to arbitrary point
end
