Question

如何将特定日期与今天进行比较，以了解特定日期是否大于今天感谢Harish。

Answer 1

@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

Answer 2

date对象具有future?和past?方法。这是我能想到的最佳方式。

Answer 3

如果您正在使用日期对象，则只需按预期进行比较。

date1 > date2

Answer 4

我个人会这样做：

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

如果我不得不与Time交易很多。现在你可以做类似

的事情了

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

我假设这就是Rails所做的事情。
