I’m not entirely clear on what you’re looking for. If you already have
this data in an array, I suggest using select {}. I.e.

data.select {|x| x >= date1 and x<= date2 }

If you’re trying to fetch the data, perhaps you’re looking for
conditions. I.e.

conditions = [ ‘date_column > ? AND date_column < ?’, date1, date2 ]

Hope that helps.

Cheers,
Darrik

You can use Date ranges. If you have strings, you’ll need to Parsedate
them into dates first. String ranges won’t understand date overflow
(ie how many days in a month, months in a year etc.).

((1.year.ago.to_date)…(Date.today)).to_a.map{|x| x.to_s(:db)}

Julian gave you almost everything. Are you asking about “Parsedate”?

Try this:

require ‘date’
date1 = Date.parse(‘2009-01-02’)
date2 = Date.parse(‘2009-01-10’)
(date1…date2).to_a

irb> puts (date1…date2).to_a
2009-01-02
2009-01-03
2009-01-04
2009-01-05
2009-01-06
2009-01-07
2009-01-08
2009-01-09
2009-01-10
=> nil

Or to make it even more clear, try 2009-02-25 to 2009-03-05

irb> puts (Date.parse(‘2009-02-25’)…Date.parse(‘2009-03-05’)).to_a
2009-02-25
2009-02-26
2009-02-27
2009-02-28
2009-03-01
2009-03-02
2009-03-03
2009-03-04
2009-03-05
=> nil
