Replace umlaute (äüö) for SEO link in rails - best way

I'm using the permalink_fu plugin to create permalinks from titles. My problem is: If the title contains german characters, they are just replaced with '_'.

What I need is something that replaces ä with ae ü with ue ö with oe

I fount String.tr but the problem here is that it replaces 1 character with 1 replacement, so it would work for replacing

é with e ø with o

etc.

Does anyone have a nice and clean solution for that?

Thanks

Solution

  • Use String.gsub():

    "ich bin doch nicht blöd, mann!".gsub(/[äöü]/) do |match|
    case match
        when "ä"
          'ae'
        when "ö"
          'oe'
        when "ü"
          'ue'
    end
end

    Of course, the lookup can be improved by using a lookup table, but the principle should be clear.
