Overview

Allows the declaration of events to be triggered.

Example:

class User < Person
  def save
    ...
  end
end

user = User.new
user.before(:save) { puts "Saving user..." }
user.after(:save) { puts "User saved." }
user.save

The block yields the object itself, so it’s possible to construct callbacks like this:

user.before :save do |u|
  u.encrypt_password!
end
