主要为
- 对框架返回的信息的本地化
- 对数据库表项目的本地化
- 对页面文字的本地化
以下是我的一个例子，点这里看效果
实现对 英文，中文，日文 三种语言的支持
RAILS_ROOT/app/controller/application_controller.rb
RAILS_ROOT/config/initializers/i18n.rb
RAILS_ROOT/coonfig/locales/en.yml
RAILS_ROOT/coonfig/locales/zh.yml
RAILS_ROOT/coonfig/locales/ja.yml
application_controller.rb
# 为本地化处理加一个过滤器
class ApplicationController < ActionController::Base
before_filter :set_locale
protected
def set_locale
session[:locale] = params[:locale] if params[:locale]
I18n.locale = session[:locale] || I18n.default_locale
end
end

I18n.default_locale = 'en'

LANGUAGES = {
'English' => 'en',
'中文' => 'zh',
'日本語' => 'ja'
}
