leods92 / group_date.rb

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.
