readable_inspect() click to toggle source

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
to_date() click to toggle source

A method to keep Time, Date and DateTime instances interchangeable on conversions. In this case, it simply returns self.

# File lib/active_support/core_ext/date/conversions.rb, line 72
def to_date
  self
end
to_datetime() click to toggle source

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.

Examples

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
to_formatted_s(format = :default) click to toggle source

Convert to a formatted string. See DATE_FORMATS for predefined formats.

This method is aliased to to_s.

Examples

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"

Adding your own time formats to to_formatted_s

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
to_time(form = :local) click to toggle source

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).

Examples

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
xmlschema() click to toggle source
# File lib/active_support/core_ext/date/conversions.rb, line 101
def xmlschema
  to_time.xmlschema
end
