Of course, you probably don't want to manually include the locale in every URL all over your application, or want the URLs look differently, e.g. the usual +http://example.com/pt/books+ versus +http://example.com/en/books+. Let's discuss the different options you have.
IMPORTANT: The following examples rely on having available locales loaded into your application as an array of strings like +["en", "es", "gr"]+. This is not included in the current version of Rails 2.2 -- the forthcoming Rails version 2.3 will contain the easy accessor +available_locales+. (See "this commit":http://github.com/svenfuchs/i18n/commit/411f8fe7c8f3f89e9b6b921fa62ed66cb92f3af4 and background at "Rails I18n Wiki":http://rails-i18n.org/wiki/pages/i18n-available_locales.)
So, for having available locales easily accessible in Rails 2.2, we have to include this support manually in an initializer, like this:
<ruby>
# config/initializers/available_locales.rb
#
# Get loaded locales conveniently
# See http://rails-i18n.org/wiki/pages/i18n-available_locales
module I18n
class << self
def available_locales; backend.available_locales; end
end
module Backend
class Simple
def available_locales; translations.keys.collect { |l| l.to_s }.sort; end
end
end
end
# You need to "force-initialize" loaded locales
I18n.backend.send(:init_translations)
AVAILABLE_LOCALES = I18n.backend.available_locales
RAILS_DEFAULT_LOGGER.debug "* Loaded locales: #{AVAILABLE_LOCALES.inspect}"
</ruby>
You can then wrap the constant for easy access in ApplicationController:
<ruby>
class ApplicationController < ActionController::Base
def available_locales; AVAILABLE_LOCALES; end
end
</ruby>
h4. Setting the Locale from the Domain Name
One option you have is to set the locale from the domain name where your application runs. For example, we want +www.example.com+ to load the English (or default) locale, and +www.example.es+ to load the Spanish locale. Thus the _top-level domain name_ is used for locale setting. This has several advantages:
