Hi,
I am new to Ruby/Rails but totally fall in love with 
Nonetheless, today I am totally stuck with Ri18n. I basically followed
the 10 Steps to Make Your Rails Apps Multilingual. No errors are
thrown,
the english version works as before with the freshly added <%= _(‘’) %>
Still, no translations are performed. Setting I18nService.instance.lang
= ‘de’ manually, I expected a translation to germany for all pages.
Rakefile works perfectly with “rake gettext”:
…
Ri18n
task :gettext do
require ‘i18nservice’
require ‘gettext’
I18nService.instance.po_dir = ‘locale’
Rake::GettextTask.new do |t|
t.new_langs = [‘de’]
t.source_files =
[‘{lib,app,components}/**/*.r{b,html,xml}’]
t.verbose = true
end
end
environment.rb states:
Include your application configuration below
Require Rails libraries (Ri18n)
require ‘rubygems’
require ‘gettext’
require ‘i18nservice’
$KCODE = ‘u’ # unicode
require ‘jcode’ # correct string methods for
utf8
I18nService.instance.po_dir = “locale” # original:
“#{RAILS_ROOT}/locale”
I18nService.instance.lang = ‘de’
ADDITIONAL_LOAD_PATHS.concat %w(
# … other entries
vendor
vendor/ri18n/lib
# … other entries
).map { |dir| “#{RAILS_ROOT}/#{dir}” }.select { |dir|
File.directory?(dir) }
/locale/de.po states:

It seems, that it just does not find the translations and therefore
displays the english version - but why?
Could someone kindly point me in the right direction?
Kind regards

PS:
I also tried to set language depending on browser, but this did not
work
with a browser requesting ‘de’, worked righted with a browser
requesting
en 
Error: can’t convert nil into String
in application.rb
class ApplicationController < ActionController::Base
before_filter :localize
before_filter :authenticate, :except => [:login, :sign_on]
private
def localize
lang = if @request.env[‘HTTP_ACCEPT_LANGUAGE’].nil?
‘en’
else
lang = @request.env[‘HTTP_ACCEPT_LANGUAGE’].split(‘-’)[0]
end
I18nService.instance.lang = lang
end
