You can use update_columns See this http://edgeguides.rubyonrails.org/active_record_callbacks.html#skipping-callbacks

Is there any specific condition like when you don't have endtime then only you need to set end time if that the you can do

def set_endtime 
   if endtime.nil? 
     self.endtime=self.starttime+self.auctiontimer 
   end 
end 

OR

before_update :set_endtime if: Proc.new { |obj| obj.endtime.nil? }
