Is it possible to create a list of months between two dates in Rails

Question

I am trying to create a page to display a list of links for each month, grouped into years. The months need to be between two dates, Today, and The date of the first entry.<

Answer 1

The following code will add a months_between instance method to the Date class

#!/usr/bin/ruby 

require 'date'

class Date

  def self.months_between(d1, d2)
    months = []
    start_date = Date.civil(d1.year, d1.month, 1)
    end_date = Date.civil(d2.year, d2.month, 1)

    raise ArgumentError unless d1 <= d2

    while (start_date < end_date)
      months << start_date
      start_date = start_date >>1
    end

    months << end_date

  end
end

This is VERY lightly tested, however it returns an Array of dates each date being the 1st day in each affected month.
