You can get a list of matching languages in the right order like so:
@matches = @languages.collect {|s| s[0..1]} & SUPPORTED_LANGUAGES.flatten
# ["en"]

SUPPORTED_LANGUAGES = { "en" => "English", "de" => "German" }
Mime::Type.parse(request.accept_language).inject(nil) do |result,mime_type|
result ||= SUPPORTED_LANGUAGES[mime_type.to_s.first(2)]
end

gem install http_accept_language
# usage (from http_accept_language's documentation, exemple two is what was sought):
class SomeController < ApplicationController
def some_action
request.user_preferred_languages
# => [ 'nl-NL', 'nl-BE', 'nl', 'en-US', 'en' ]
available = %w{en en-US nl-BE}
request.preferred_language_from(available)
# => 'nl-BE'
request.user_preferred_languages
# => [ 'en-GB']
available = %w{en-US}
request.compatible_language_from(available)
# => 'en-US'
end
end
This is some rails code where I want to take the HTTP_ACCEPT_LANGUAGE header and match it to an array of supported languages. It looks awful here, I know there must be a better way to do this, right?
