Question : age calculation

Hi experts,

I am trying to calculate age in rails.

I did something like this, but I know I am not considering leap years/months.

class AttendingIp < ActiveRecord::Base
  def age
   
     
     age = Date.today.year - read_attribute(:dob).year
     if Date.today.month < read_attribute(:dob).month ||
     (Date.today.month == read_attribute(:dob).month && read_attribute(:dob).day >= Date.today.day)
      age = age - 1    
      end
     
        month = Date.today.month - read_attribute(:dob).month
      if(Date.today.month < read_attribute(:dob).month)
       month = 12 - read_attribute(:dob).month
      end
     
       day = Date.today.day - read_attribute(:dob).day
      if(Date.today.day < read_attribute(:dob).day)
       day = 31 - read_attribute(:dob).day
      end

I went through ruby api, but didn't find solution. Is there nice way to do this in RoR?

thanks in advance

Answer : age calculation

here is the code, that should already be a lot faster

y_dif = now.year - born.year
if Date.new(now.year - y_dif, now.month, now.day) < born
      y_dif = y_dif - 1
end

m_tot = 0
almost_close_date = Date.new(born.year + y_dif, born.month, born.day)
while almost_close_date < now
      m_tot = m_tot + 1
      almost_close_date = almost_close_date>>(1)
end
m_dif = m_tot - 1

close_date = born >>(m_dif + 12 * y_dif)
d_dif = 0
while close_date < now
      d_dif = d_dif + 1
      close_date = close_date+(1)
end

puts y_dif, m_dif, d_dif

If this is still too slow,
you could make the day count recursive and split day differences in two (such as in bubble sort :-)

but before you go down that route, check pl/sql first
using the ruby code is less database dependent of course
