Proszę bardzo. Oto wersja w której jest pochodną klasy Parent:

class Child1 < Parent
   set_dataset DB[:childs1]
   set_schema do
     primary_key :parent_id
     varchar :pole1
   end
   before_save do
     unless Parent[Child1.max(:parent_id).to_i + 1]
       raise 'Parent cannot assign more childs1 objects'
     end
   end
end
