"國際化"

多國語言是一個國際型必備的要素，來看看 Rails 如何做多國語言吧
這邊我們想要有 英文版 和 繁體中文版 兩種

首先，做好詞彙表

config/locales/en.yml

en:
  hello: "Hello world"
  index: "Index Page of Girb"
  button:
    new: "New"
  placeholder:
    search_name: "Search Name"





config/locales/zh_tw.yml

zh-TW:
  hello: "哈囉"
  index: "個首頁"
  button:
    new: "新增"
  placeholder:
    search_name: "名字搜尋"

到 application_controller.rb 修改程式碼如下：

class ApplicationController < ActionController::Base
  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  before_filter :set_locale
  protect_from_forgery with: :exception

  def set_locale
    if params[:locale] && I18n.available_locales.include?( params[:locale].to_sym )
      session[:locale] = params[:locale]
    end

    I18n.locale = session[:locale] || I18n.default_locale
  end
end

接下來去 views 把想換成多國語言的地方給置換掉

app/views/girbs/index.html.erb

<div class="container">
  <h1><%= t('index') %> ( <%= @girbs.count %> )
  <% if @girbs.count != Girb.all.count %>( Filter: <%= @girbs.first.level %> ) <% end %></h1>
  <%= will_paginate @products %>
  <span class="pull-right">
.
.
.
  <%= form_tag(girbs_path, method: :get, id: "search-form") do %>
  <%= text_field_tag :search, params[:search], placeholder: t('placeholder.search_name') %>
  <%= submit_tag "Search", name: nil %>
  <% end %>






app/views/layouts/application.html.erb

    <!-- start of footer -->
    <div class = "navbar navbar-default navbar-fixed-bottom">
      <div class = "container">
        
        <sapn class = "navbar-text">Site Built By Hazetodo  </span>
        <%= link_to "Bilink", girbs_path, :class => "navbar-btn btn-danger btn btn-sm" %>
        <%= link_to new_girb_path, :class => "navbar-btn btn btn-primary btn-sm " do %>
        <i class=" fa fa-plus fa-sm"></i> <%= t 'button.new' %>
        <% end %>
        <%= link_to raw('<i class="fa fa-plus fa-sm"></i> New'), new_girb_path, :class => "navbar-btn btn btn-warning btn-sm" %>
        
      </div>
    </div>
    <!-- end of footer -->
