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. 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 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.
