如何迭代天
我有一个循环 days.this 的代码来制作树叶。我希望出勤时的列登录和注销将在开始日期开始并在结束日期结束时自动填充。
**exp I input :**
startdate: 2012-11-08 01:30:00
enddate: 2012-11-10 01:30:00
**i want output like this:**
2012-11-08 01:30:00
2012-11-09 01:30:00
2012-11-010 01:30:00
for i in 0..((@leafe.enddate - @leafe.startdate).to_i)
@attendance = Attendance.new
@attendance.signin = '2012-11-08 01:30:00' #value must change automatically
@attendance.signout = '2012-11-08 10:30:00'#value must change automatically
@attendance.user_id = @leafe.user_id
@attendance.save
end
对于你的回答,我说谢谢
