Converting dates to formatted strings, times, and datetimes.
Overrides the default inspect method with a human readable one, e.g., "Mon, 21 Feb 2005"
# File lib/active_support/core_ext/date/conversions.rb, line 66 def readable_inspect strftime("%a, %d %b %Y") end
Converts a Date instance to a DateTime, where the time is set to the beginning of the day and UTC offset is set to 0.
date = Date.new(2007, 11, 10) # => Sat, 10 Nov 2007 date.to_datetime # => Sat, 10 Nov 2007 00:00:00 0000
# File lib/active_support/core_ext/date/conversions.rb, line 97 def to_datetime ::DateTime.civil(year, month, day, 0, 0, 0, 0) end
Convert to a formatted string. See DATE_FORMATS for predefined formats.
This method is aliased to to_s.
date = Date.new(2007, 11, 10) # => Sat, 10 Nov 2007 date.to_formatted_s(:db) # => "2007-11-10" date.to_s(:db) # => "2007-11-10" date.to_formatted_s(:short) # => "10 Nov" date.to_formatted_s(:long) # => "November 10, 2007" date.to_formatted_s(:long_ordinal) # => "November 10th, 2007" date.to_formatted_s(:rfc822) # => "10 Nov 2007"
You can add your own formats to the Date::DATE_FORMATS hash. Use the format name as the hash key and either a strftime string or Proc instance that takes a date argument as the value.
# config/initializers/time_formats.rb Date::DATE_FORMATS[:month_and_year] = "%B %Y" Date::DATE_FORMATS[:short_ordinal] = lambda { |date| date.strftime("%B #{date.day.ordinalize}") }
# File lib/active_support/core_ext/date/conversions.rb, line 53 def to_formatted_s(format = :default) if formatter = DATE_FORMATS[format] if formatter.respond_to?(:call) formatter.call(self).to_s else strftime(formatter) end else to_default_s end end
Converts a Date instance to a Time, where the time is set to the beginning of the day. The timezone can be either :local or :utc (default :local).
date = Date.new(2007, 11, 10) # => Sat, 10 Nov 2007 date.to_time # => Sat Nov 10 00:00:00 0800 2007 date.to_time(:local) # => Sat Nov 10 00:00:00 0800 2007 date.to_time(:utc) # => Sat Nov 10 00:00:00 UTC 2007
# File lib/active_support/core_ext/date/conversions.rb, line 86 def to_time(form = :local) ::Time.send("#{form}_time", year, month, day) end
