Do you have a preferred programming pattern for adding functionality to an ActiveRecord? As an example, say I have some gnarly trig functions for distance and bearing between pairs of latitude and longitude:
=== file: latlng.rb module LatLng def haversine_distance(lat1, lng1, lat2, lng2) ... end def bearing(lat1, lng1, lat2, lng2) ... end === EOF ... and I want to mix in haversine_distance(other_ar) and bearing(other_ar) methods into an ActiveRecord. The shim functions would look like this: === def haversine_distance(other_ar) haversine_distance(self.lat, self.lng, other_ar.lat, other_ar.lng) end def bearing(other_ar) bearing(self.lat, self.lng, other_ar.lat, other_ar.lng) end === BUT: What are your preferred methods for packing this up in to modules? What are the preferred names for modules? Where do you put the files? Do you include the computational methods in the same file as the shim functions? Etc... Extending AR functionality is relatively common, but I haven't yet seen a dominant pattern for doing so. I don't expect really coherent answers from such an open ended question, but I'm curious what techniques people have seen and like. - ff -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
