Rails ActiveRecord date between
I need to query comments made in one day. The field is part of the standard timestamps, is created_at. The selected date is coming from a date_select. How can I use ActiveRecord to do that? I need something like: "SELECT * FROM comments WHERE created_at BETWEEN '2010-02-03 00:00:00' AND '2010-02-03 23:59:59'"
