As a starting point, IIWM I would: * Get the ten times either side (so I have twenty objects). * Calculate the difference of how far each is from the event (ignoring sign) * Order the twenty by the difference * Take the first ten of them. With a bit of thought this could all be done in SQL... possibly with a couple of sub-queries. But it could certainly be stepped through in Ruby very easily. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
