Each node contains only a name and a reference to its father: class Node < ActiveRecord :: Base validates_presence_of : name , : parent_id end The table isn't very big - less than 100 elements. It's updated rarely - in the last 4 months 20 new elements were added, in one occasion, by the site admin. Yet it is used quite a lot on my application. Given its tree-like structure, on some occasions a request triggers more than 30 database hits (including

I have require 'authlogic' in the ruby script I'm new to ruby modules but was trying to call the password method like: Authlogic::ActsAsAuthentic:

I've watched the railscasts episode on it, but I did not feel like he was using the best practice when creating the form. I felt like it was a sloppy way to accomplish the task.
