ruby on rails - Random default value for integer in database for each instance? -

i'm using system voting content in rails app: https://github.com/twitter/activerecord-reputation-system

is there way make default score votable item random number each instance.

if store rand(5..12) pick random default value 1 time, how random default value every different row or field?

      create_table "rs_evaluations", :force => true |t| t.string   "reputation_name" t.integer  "source_id" t.string   "source_type" t.integer  "target_id" t.string   "target_type" t.float    "value",           :default => 0.0 t.datetime "created_at",                       :null => false t.datetime "updated_at",                       :null => false 

end

use before_create filter.

class rsevaluation < activerecord::base    before_create :update_value    def update_value     self.value = rand(5..12)   end  end 

however; since evaluation not own model, 1 library, try opening class , patching it:

module reputationsystem    class evaluation < activerecord::base     before_create :update_value      def update_value       self.value = rand(5..12)     end   end  end 

this placed in config/initializers folder.
