  Make use of recursive queries in Rails when using Postgresql or SQLite

  

The other option is to use something like the acts_as_recursive_tree gem, which is a much narrower implementation. The upside is that you get your tree pretty easily and you can make use of pretty performant SQL. The downside is that it's more rigid, which means that if/when your requirements change you may end up having to either figure out how to modify this thing or rewrite meaningful sections from scratch.
