Here’s an implementation of Range#to_formatted_s that lets you retrieve range formats from your locale bank.
It’s true that you can write your own range conversions and add them to ::Range::RANGE_FORMATS. Those conversions could refer to translations in your locale bank, but I’d prefer to see what the range formatter is doing without having to look in two places. I wanted a formatter that would do something like this, where :fancy can represent a different Proc depending on the current locale:
>> (Time.current..Time.current+1.hour).to_s :fancy => "Monday, February 16th, 2009 between 6:00pm and 7:00pm PST"
First, I implemented a version of Range#to_formatted_s that’s I18n aware (thanks clemens!).
config/initializers/range_conversions.rb:
# Allows you to do things like (Time.current..Time.current+1.day).to_s :local_format # where range.format.local_format is an entry in one of your locale files ::Range.class_eval do def to_formatted_s(format = :default) formats = ::Range::RANGE_FORMATS formatter = formats[format] unless formatter formatters = I18n.translate(:'range.formats', :raise => true) rescue {} formatter = formatters[format] end formatter.respond_to?(:call) ? formatter.call(self.begin, self.end) : to_default_s end alias_method :to_s, :to_formatted_s end
Next, I edited my locale file:
config/locales/en.rb:
{ :en => { # Range :range => { :formats => { :fancy => lambda { |start_time, finish_time| start_format = "%B #{start_time.day.ordinalize}, %Y between %l:%M%p" finish_format = "%l:%M%p %Z" "#{I18n.localize(start_time, :format => start_format)} and #{I18n.localize(finish_time, :format => finish_format)}" } } } } }
And there you have it; fancy-formatted date ranges with localization.
