Plugins - attr_hidden
Add to favoritesActive Record uses single table inheritance to allow to represent in the database a hierarchy of objects.
Sometimes however you would like to hide some columns of the general table from some subclasses, as these columns only have a meaning in some other subclasses.
Using this plugin will allow it, as simple as writing:
attr_hidden :attr1, :attr2
in the class where you would like to hide attr1 and attr2.
