Loop over hour:minute

Question

I'm with Rails 4:

I need to make a loop in a table to display time of the day as title of column, like that

8:00 | 8:30 | 9:00 .... 20:00 | 20:30 | 21:00

Do you have any idea how to define the loop? I've try complicated things with step() but meaby I have miss a easy way using Time?

Thanks

I didn't understand, you need to display time slots of the day? like: 00:00| 00:30| 01:00|01:30....|23:00|23:30|?? — Surya, Jul 09 '14 at 20:32

You could use Rails DateTime like this (for n steps you want)

startdate = DateTime.new(2001,2,3) 
interval = 30
formatstr = '%H:%M'
(0..n).map{|offset| startdate + (offset * interval).minutes }
      .map{|date| date.strftime(formatstr)}
