Package: ruby-rails-observers
Description: toolkit to build Rails observers (part of Rails)
This package contains two observers: Active Record Observer and
Action Controller Sweeper.
Active Record Observer classes respond to life cycle callbacks to
implement trigger-like behavior outside the original class. This is a
great way to reduce the clutter that normally comes when the model
class is burdened with functionality that doesn't pertain to the core
responsibility of the class.
Active Record Sweepers are the terminators of the caching world and
responsible for expiring caches when model objects change. They do
this by being half-observers, half-filters and implementing callbacks
for both roles.
