Better way to do this?

Hi,


Also I was reading something about {} last night and it looks like I
could write this as
total = 0
7.times do |i| { total += row.send("day" + (i+1).to_s) }
They both are pretty legible to me, but is there a major convention I
should follow?


How about:
total = 0
1.upto(7) { |i| total += row.send("day#{i}") }

How about a one-liner?

total = (1…7).inject {|sum, i| sum + row.send “day#{i}”}
