DataMapper::Observer allows you to add callback hooks to many models. This is
similar to observers in ActiveRecord.
Example:
class Adam
include DataMapper::Resource
property :id, Serial
property :name, String
end
class AdamObserver
include DataMapper::Observer
observe Adam
before :save do
# log message
end
before :get_drunk do
# eat something
end
after_class_method :unite do
raise "Call for help!"
end
end
