Ruby on Rails

Yes, if the member will become an artist but and artist still has all the attributes of a member, is better to have one model with conditional validation, something like.


validates :master_piece, :presence => true, :if => is_artist?



def is_artist?
 artist
end


and in the view i would put some


<%= @member.master_piece if member.is_artist?%>


all these IF artist are member. I would use STI if member are not artist but share a few fields like name and so, but if an artist has all the fields a member has and a few more, there is no need for STI.
