This package contains AASM, a library for adding finite state machines to Ruby classes.
AASM started as the acts_as_state_machine plugin but has evolved into a more generic library that no longer targets only ActiveRecord models.
AASM has the following features:
States
Machines
Events
Transitions
The latest AASM can currently be pulled from the git repository on github.
A release and a gem are forthcoming.
% sudo gem sources -a http://gems.github.com # (you only need to do this once) % sudo gem install rubyist-aasm
% rake gem % sudo gem install pkg/aasm-2.0.1.gem
Here’s a quick example highlighting some of the features.
