This gem allows you to easily use [Hashids](http://hashids.org/ruby/) in your Rails app. Instead of your models using sequential numbers like 1, 2, 3, they will instead have unique short hashes like "yLA6m0oM", "5bAyD0LO", and "wz3MZ49l". The database will still use integers under the hood, so this gem can be added or removed at any time.

RubyTree is a Ruby implementation of the generic tree data structure. It provides simple APIs to store named nodes, and to access, modify, and traverse the tree. The data model is node-centric, where nodes in the tree are the primary structural elements. It supports all common tree-traversal methods (pre-order, post-order, and breadth first). RubyTree mixes in the Enumerable and Comparable modules and behaves like a standard Ruby collection (iteration, comparison, etc.). RubyTree also includes a binary tree implementation, which provides in-order node traversal besides the other methods. RubyTree can import from and export to JSON, and supports Ruby’s object marshaling.
