ruby-on-rails – Rails cron作业每天运行2年后创建数据库记录.

根据我目前的逻辑,我很好奇当闰年会发生什么,并且有没有办法让这个更加强大以正确处理闰年？我担心我要么结束一天完全错过的日子,要么结束一天的重复.

task :generate_timeslots => :environment do

    startDate = Time.now.to_date + 2.years
    endDate = Time.now.to_date + 2.years

    startDate.upto(endDate).each do |d|

    5.times do  
       timeslot = Timeslot.create
       timeslot.location_id = 1
       timeslot.timeslot = "#{d} 09:00:00"
       timeslot.save

       timeslot = Timeslot.create
       timeslot.location_id = 1
       timeslot.timeslot = "#{d} 11:00:00"
       timeslot.save

       timeslot = Timeslot.create
       timeslot.location_id = 1
       timeslot.timeslot = "#{d} 13:00:00"
       timeslot.save

       timeslot = Timeslot.create
       timeslot.location_id = 1
       timeslot.timeslot = "#{d} 15:00:00"
       timeslot.save
    end
    end
end
