Adds time zone aware data grouping method to ActiveRecord. If you want to group a large set of database rows by date using a timestamp as reference, the optimal way is to do it right in the database. When doing it though there are some issues with time zones that #group_date solves. For example, if a UTC timestamp is set to 2013-12-01 01:00 and …
module ActiveRecord
module Querying
delegate :group_date, :to => :scoped
end
module QueryMethods
def group_date(column_name = nil)
return self if column_name.blank?
# Rails uses a non standard time zone naming.
