ruby-rails-observers
toolkit to build Rails observers (part of Rails)
Description
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.Upload more screenshots
