Description-en: 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.
