Nested sets in rails 0.12.1
Nested sets are one of my very favorite structures. It is a structure that allows you to deal with arbitrarily deeply nested hierarchies. I saw with release 0.12 of rails that there was a new :acts_as_nested_set keyword in the model layer. I have spent the last two nights trying to get this code to work, and so far I haven't had any luck. Even if the code works as written, I think I'm going to try to get a better implementation in place. Having worked with this structure quite a bit, I'm pretty sure I can add a few things that will make it easier to work with and more powerful overall. Still I have to say I'm pretty impressed that there is *any* type of support for nested sets. Just one more item in a long list of items that have impressed me deeply with Ruby On Rails.
I actually wrote the nested set implementation. You're happy to do whatever you want to with it of course, but I'm curious exactly what thoughts or issues you have with it.
