Rails - Mar 2007 - Extending the to_s method

Hi!

I''m developing an localization plugin (just for my own purposes) and I
wanted to extend the to_s method for the Time class.

What I want to do:
when someone does date.to_s(:short) that a localized version of
the :short date is displayed.
But I don''t know how to accomplish this. I know have this:

class Time
  def to_s(option)
    print option.to_yaml
    ''lalo''
  end
end

Jepp... it prints all the the times to ''lalo'' :)

But how do I adjust this method so that only in the case of :short the
return value is modified?
Something like:

if option == :short {
  return self.strftime("%Y %D %E")
}

Or is there more to it?

Thanks in advance!

Hi,

Maybe more concrete:

I have a model with an attribute called "ammount". It''s a
price stored
in an integer (in cents). Is it possible to extend the to_s method for
that attribute? So that I will show "€ 20,00" when I do: <%=
ammount
%>
