In controller I use to raise some specific error as follows :

include CustomErrors

rescue_from NoGuestFound,NoHostFound,NoInvitation,WrongPass do |e|
  flash[:message] = e.message
  redirect_to :action => :index

def lambda
  @guest.is_invited_by?(@host) or raise 'context

I find this way of doing pretty OK, but for AR model validation I'd like
to give back the end to the Active Record standard validation process. I
can't find good doc on how to do so and how AR validation works

if anybody has a better way to deal with error handling or if you could
give me some smart links, would appreciate !
