Getting dates in different convenient string representations and other objects
DATE_FORMATS | = | { :short => "%e %b", :long => "%B %e, %Y", :db => "%Y-%m-%d", :long_ordinal => lambda { |date| date.strftime("%B #{date.day.ordinalize}, %Y") }, # => "April 25th, 2007" :rfc822 => "%e %b %Y" |
Overrides the default inspect method with a human readable one, e.g., "Mon, 21 Feb 2005"
# File vendor/rails/activesupport/lib/active_support/core_ext/date/conversions.rb, line 57 57: def readable_inspect 58: strftime("%a, %d %b %Y") 59: end
A method to keep Time, Date and DateTime instances interchangeable on conversions. In this case, it simply returns self.
# File vendor/rails/activesupport/lib/active_support/core_ext/date/conversions.rb, line 63 63: def to_date 64: self 65: 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 vendor/rails/activesupport/lib/active_support/core_ext/date/conversions.rb, line 88 88: def to_datetime 89: ::DateTime.civil(year, month, day, 0, 0, 0, 0) 90: end
Convert to a formatted string - see DATE_FORMATS for predefined formats. You can also add your own formats to the DATE_FORMATS constant and use them with this method.
This method is also aliased as 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"
# File vendor/rails/activesupport/lib/active_support/core_ext/date/conversions.rb, line 44 44: def to_formatted_s(format = :default) 45: if formatter = DATE_FORMATS[format] 46: if formatter.respond_to?(:call) 47: formatter.call(self).to_s 48: else 49: strftime(formatter) 50: end 51: else 52: to_default_s 53: end 54: 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 vendor/rails/activesupport/lib/active_support/core_ext/date/conversions.rb, line 77 77: def to_time(form = :local) 78: ::Time.send("#{form}_time", year, month, day) 79: end
