Is there an add_days in ruby datetime?

Question

In C#, There is a method AddDays([number of days]) in DateTime class.

Is there any kind of method like this in ruby?

Answer 1

In Rails there are very useful methods of Fixnum class for this (here n is Fixnum. For example: 1,2,3.... ):

Date.today + n.seconds # you can use 1.second
Date.today + n.minutes # you can use 1.minute
Date.today + n.hours # you can use 1.hour
Date.today + n.days # you can use 1.day
Date.today + n.weeks # you can use 1.week
Date.today + n.months # you can use 1.month
Date.today + n.years # you can use 1.year

These are convenient for Time class too.

PS: require Active Support Core Extensions to use these in Ruby
