Rails I18n的关键点


1、设定locales文档。
config/locales/en.yml
------------------------------
en:
  hello: "Hello world"
  store: "Store"
------------------------------
config/locales/zh-CN.yml
------------------------------
zh-CN:
  hello: "你好"
  store: "商店"
------------------------------
2、解析locale。
app/controller/application.rb
------------------------------
  class ApplicationController < ActionController::Base
    before_filter :set_locale
    def set_locale
      I18n.locale = params[:locale] || 'zh-CN'              #如果没有，则使用默认值。
    end
    ...
  end
------------------------------
3、在控制器中读取变量
------------------------------
class StoreController < ApplicationController
  def index
    @products = Product.find_products_for_sale
    flash[:hello_flash] = t(:hello_flash)
  end
  ...
end
------------------------------
4、在视图层中使用变量
------------------------------
      <% if flash[:hello_flash] -%>
        <div id="hello_flash"><%= flash[:hello_flash] %></div>
      <% end -%>
------------------------------
