to_fs(format = :default) public

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

This method is aliased to to_formatted_s.

date = Date.new(2007, 11, 10)       # => Sat, 10 Nov 2007

date.to_fs(:db)                     # => "2007-11-10"
date.to_formatted_s(:db)            # => "2007-11-10"

date.to_fs(:short)         # => "10 Nov"
date.to_fs(:number)        # => "20071110"
date.to_fs(:long)          # => "November 10, 2007"
date.to_fs(:long_ordinal)  # => "November 10th, 2007"
date.to_fs(:rfc822)        # => "10 Nov 2007"
date.to_fs(:iso8601)       # => "2007-11-10"

Adding your own date formats to to_fs

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/date_formats.rb
Date::DATE_FORMATS[:month_and_year] = '%B %Y'
Date::DATE_FORMATS[:short_ordinal] = ->(date) { date.strftime("%B #{date.day.ordinalize}") }

  def to_fs(format = :default)
    if formatter = DATE_FORMATS[format]
      if formatter.respond_to?(:call)
        formatter.call(self).to_s
      else
        strftime(formatter)
      end
    else
      to_s
    end
  end
