Hi.. I need some support...
table:
week_id, user_id, project_id, hours
ex. =>
33, 2, 1, 10
34, 2,1,15
33, 2, 2, 20
35, 3, 1,20
etc.
Want to display a sum of hours per week_id per user_id
I have:
@hours = HourUser.includes(:user).group_by { |h| h.week_id }
@hours.keys.sort.each do |hour|
@hours[hour].collect(&:stunden).sum
Hours are summed up, but not sorted by user_id..
