Attendance Logic

allRecords = Attendance.pluck(:date, :presence).map { |attendance, presence| [attendance.strftime('%B'), presence] } #=> [['November',true],['November',false],['November',true],['December', true], ['December', false], ['January',false], ['January',true]]
monthFilter = allRecords.uniq.map { |month| [month[0]] } #=> ['November','November', 'November', 'December', 'December', 'January','January']
months = monthFilter.uniq #=> ['November','December','January']

# Expected To do the following:
# To fetch all the records and count the number of true presence with false presence per month. Then get a percentage of true / total in each month

In the end, I realized it was the percentage logic that needed to be corrected. So I had this instead

[k, "#{(Float(trues.size)/ (Float(falses.size) + Float(trues.size)) * 100).round}%"]
