How can I make a property aware of changes on another?
I have a model that needs to update a property whenever another property
changes, i.e. changing the model ''type'' property updates the
''description'' property with another value.
I don''t know how to get access to the underlying fields handled by rails
within a model class.
Thanks,
Daniel
