Hi, I want to have a go at writing an extension to my models, in a similar style to those acts_as model extensions. I want to have a sigle declaration that includes my functionality, similar to "acts_as_taggable" and then specify callbacks in a similar way to "before_filter" that my extended functionality will call. Something like:-
Class Item < ActiveRecord acts_as_widget widget_work_filter :do_widget_work
def do_widget_work ... end
end
Is there a good resource you can point me at that will explain how to do this...?
