comparision of date in ruby

how to compare particular date with today to know whether that paricular date is gr开发者_StackOverfloweater than today

Thanks Harish.

@date = "2010-07-20".to_date # 20th July
@today=Date.today # 21st July

if @date >= @today
  puts "@date is greater than or equal to today's date"
else
  puts "@date is less than today's date"  
end

O/P

@date is less than today's date

date object has future? and past? methods. It's the best way I can think of.

If you're using date objects, you just compare as expected.

date1 > date2

I would personally do something like:

class Integer
  def minutes
    self * 60
  end
  def hours
    self * 60.minutes
  end
  def days
    self * 24.hours
  end
  def weeks
    self * 7.days
  end
  def months #can probably be more accurate, but I'll just use 30.days
    self * 30.days
  end
  def years
    self * 12.months
  def
end

If I had to deal a lot with Times. Now you can do something like

t1 = Time.now
t2 = t1 + 1.days
puts "You're in the past~" if t1 < t2

I am assuming that's what Rails does anyway.
