#delegate_belongs_to(association, *attrs) ⇒ Object

TODO:

Integrate this with ActiveRecord::Dirty, so if you set a property through one of these setters and then call save on this object, it will save the associated object automatically.

Creates methods for accessing and setting attributes on an association. Uses same default list of attributes as delegates_to_association. delegate_belongs_to :contact delegate_belongs_to :contact, [:defaults] ## same as above, and useless delegate_belongs_to :contact, [:defaults, :address, :fullname], :class_name => ‘VCard’
