Overview

MassiveRecord Observer. Greatly influenced by ActiveRecord’s way of doing callbacks, thus should feel familiar to most people.

NOTE that if you are using rails you should add observers to into

your application.rb configuration file like this:

config.massive_record.observers = :person_observer, :audit_observer

This will ensure that observers are loaded correctly. If you are not
using rails you can do: MassiveRecord::ORM::Base.instantiate_observers
after your application has been initialized.

Example of usage:

class Person < MassiveRecord::ORM::Table

column_family :info do
  field :name
end

end

class PersonObserver < MassiveRecord::ORM::Observer

def after_save(saved_person_record)
  # do something here after people are being saved
end

end

class AuditObserver < MassiveRecord::ORM::Observer

observe :person, :and, :other, :classes

def after_save(saved_person_record)
  # do something here after people are being saved
end

end
