I have a standard ActiveRecord model with the following:
class MyModel < ActiveRecord::Base
custom_method :first_field, :second_field
end
At the moment, that custom_method is picked up by a module sent to ActiveRecord::Base. The functionality basically works, but of course, it attaches itself to every model class, not just MyModel. So if I have MyModel and MyOtherModel in the same action, it'll assume MyOtherModel has custom_method :first_field, :second_field as well.
So, my question is: How do I attach a method (eg: def custom_method(*args)) to every class that inherits from ActiveRecord::Base, but not by attaching it to ActiveRecord::Base itself?
Any ideas appreciated.
