本文主要是介绍艰难的globalize 历程 (半成品，多谢Eric和cookoo 的指点，将继续补充)，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
Globalize 绝对不是像其网址上的说得那么简单易用，部署的过程中多次有放弃并用手工来汉化的念头。这个网站wiki曾经给涂鸦的不成样子了
http://www.globalize-rails.org/
有时候可以正常的访问, 如有异常
可以访问Trac的
http://svn.globalize-rails.org/trac/globalize
或
http://wiki.globalize-rails.org/globalize/

光说不练，天桥把式
Beast 汉化示范
安装禽兽不难, 看下面的步骤
http://www.olddognewtricks.co.uk/2006/09/beast.html
能行吗?
不行, 就一步一步地来吧
svn 你有吧, 看准了windows下2进制文件的---------安装方便点
[img]http://subversion.tigris.org/subversion_logo_hor-468x64.png[/img]
http://subversion.tigris.org/servlets/ProjectDocumentList?folderID=91
windows 平台用
http://subversion.tigris.org/files/documents/15/34093/svn-1.4.0-setup.exe
对小海龟的客户端, 没有就下, 图式界面适合初学者

svn checkout http://svn.techno-weenie.net/projects/beast/trunk/
:D checkout 就像download一样下载代码到你的PC上了
rake freeze_edge
:) beast还没进化, 用的是Rails 1.2 版, 有安全漏洞的版哦
gem install RedCloth
:roll: 装红布
:arrow: database.yml 修改数据库的配置（用mysql的话，Mysql里建立个空的schema 名字与yml里的一样，注意用户密码，比如root， ）
导入数据表
rake db:schema:load RAILS_ENV=production
:lol: 把加密的salt盐值改了
PASSWORD_SALT 在 config/environment.rb
用ruby script/server -e production 启动
localhost：3000 IE 浏览器就看到了野兽，吼叫吧，现注册

可以开始Globalize啦
回顾前提条件
Beast(别的RoR程序也可以)已经安装部署好了, 可以运行。
检查确认数据库的设置 conf/database.yml
安装设置 Globalize
ruby script/plugin install http://svn.globalize-rails.org/svn/
globalize/globalize/branches/for-1.1
这个命令有问题，因为svn库里的路径有变化
可以svn 直接把/for-1.1 checkout 到vendor 路径下
命令如下
cd vendor/plugins
svn export svn://svn.globalize-rails.org/globalize/branches/for-1.1 --force
然后回到项目的根目录
下一步配置, 就是在创建翻译表, 留意你的数据库配置和服务在运行中
rake globalize:setup
报错
Mysql::Error: Identifier name
'index_globalize_translations_on_table_name_and_item_id_and_language_id'
is

`index_globalize_translations_on_table_name_and_item_id_and_language_id`

Just add a
:name => „something_idx“
parameter to the add_index statement.
Btw. If you have the same problem with foreign_keys:
1) create an index with a shorter name
2) add_fkey …, :name => “something_fk”, :index => false
does the trick.
Also you can handle the identifier name limit for the foreign key itself
and index with a possibly too long name will be auto created …unless you
use the :index => false option. On most (all?) RDBMS you need an index
for foreign keys column(s) though.

上面的介绍不详细, 从数据库里看到表的结构已经建立了,但没有数据,在创建index时候出了问题
cd db
cd migrate
044_globalize_migration.rb 打开有
[img]http://bd7lx.iteye.com/upload/picture/pic/196/67347577-96fa-4afc-bfe3-81a30f457a88.jpg[/img]
找add_index的字段
按上面的Bernd方法,还是不行,提示index建立时出错, :?:
把add_index屏蔽掉, 不是所有....哈
重新运行 rake globalize:setup
检查beast数据库里多了表和数据, Ok
[color=darkred]下一步该Configuration[/color]
config/environment.rb 文件里加入下面的代码， 放在initial xxxx
end 的后面:
[code]# Include your application configuration below
include Globalize
Locale.set_base_language 'en-US'
LOCALES = {'pl' => 'pl-PL',
'en' => 'en-US',
'es' => 'es-ES',
'fr' => 'fr-FR'}.freeze[/code]
LOCALES = {'pl' => 'pl-PL',
'en' => 'en-US',
'es' => 'es-ES',
'fr' => 'fr-FR'}.freeze
可以做相应的修改,
LOCALES = {
'en' => 'en-US',
'zh' => 'zh-CN'
}.freeze
或直接用
Locale.set_base_language('en-US')
config/routes.rb 的文件也来点：
[code]map.connect ':locale/:controller/:action/:id'[/code]
app/controllers/application.rb file:
[code]
class ApplicationController < ActionController::Base
before_filter :set_locale
def set_locale
if !params[:locale].nil? && LOCALES.keys.include?(params[:locale])
Locale.set LOCALES[params[:locale]]
else
redirect_to params.merge( 'locale' => Locale.base_language.code )
end
end
end[/code]
如果再次启动webrick则 localhost:3000的指向为http://localhost:3000/en/forums
:evil: 翻译静态的内容 static content.
生成个翻译的控制器
ruby script/generate controller admin/translate
修改控制器
[code]
class Admin::TranslateController < ApplicationController
def index
@view_translations = ViewTranslation.find(:all, :conditions => [ 'built_in IS NULL AND language_id = ?', Locale.language.id ], :order => 'text')
end
def translation_text
@translation = ViewTranslation.find(params[:id])
render :text => @translation.text || ""
end
def set_translation_text
@translation = ViewTranslation.find(params[:id])
previous = @translation.text
@translation.text = params[:value]
@translation.text = previous unless @translation.save
render :partial => "translation_text", :object => @translation.text
end
end[/code]
创建 app/views/admin/translate/_translation_text.rhtml 局部页面, 里面用来 translation_text action.
[quote]
<%= translation_text || '[no translation]' %>
[/quote]
要翻译静态内容可以使用 in_place_editor helper帮助类（内置在Rails 1.1） , 记着加入下面的代码
<%= javascript_include_tag :defaults %>
到 layout file ( admin 部分)
比如 创建一个程序应用范围的
[size=18]app/views/layouts/application.rhtml[/size] layout –
可以copy 大多数的生成的products.rhtml , 只改标题并加上 javascript tag 标签
下面接着创建
app/views/admin/translate/_translation_form.rhtml
partial 局部模板给the form 这个是用来提供翻译的.
[code]
<!--[form:translate]-->
<p>
<label for="tr_<%= tr.id %>"><%=tr.tr_key%></label>
<br />
<span id="tr_<%= tr.id %>">
<%= render :partial => 'translation_text', :object => tr.text %>
</span>
<%= in_place_editor "tr_#{tr.id}",
:url => { :action => :set_translation_text, :id => tr.id },
:load_text_url => url_for({ :action => :translation_text, :id => tr.id })%>
</p>
<!--[eoform:translate]-->[/code]
帮助类中添加 app/helpers/application_helper.rb file:
[code]def base_language_only
yield if Locale.base?
end
def not_base_language
yield unless Locale.base?
end
[/code]
:P
在 app/views/admin/translate, 建个 index.rhtml
[code]
<% base_language_only do -%>
<div id="language"><h1>Please choose language for translation</h1></div>
<% end -%>
<% not_base_language do -%>
<div id="language"><h1><%= "Language: " + Locale.language.native_name %></h1></div>
<div>
<% @view_translations.each do |tr| -%>
<%= render :partial => 'translation_form', :locals => {:tr => tr}%>
<% end -%>
</div>
<% end -%>
[/code]
