Question

我正在开发一个多语言（EN / RU）网站，我需要一个允许我翻译数据库记录的解决方案？

是否有任何第三方插件可以让您维护多语种网站？理想情况下，它应该与rails_admin（或最坏情况下的脚手架）和routing-filter一起使用。

我现在使用globalize3，它也会通过rails_admin创建翻译。但是没有办法指定语言环境。它只为您当前的语言环境创建翻译，即无法真正翻译记录，因为它只是复制原始条目。我认为无法创建英文翻译。

提前致谢！

配置/ application.rb中

config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
config.i18n.default_locale = :ru

模型/ page.rb

class Page < ActiveRecord::Base
  translates :title, :content
  validates_presence_of :title
end

Rails控制台输出：

Answer 1

如果您只有两种语言，最好将翻译保留在同一个表格中，例如：

create_table "articles" do |t|
  ...
  t.column "title_ru", :string
  t.column "title_en", :string
  t.column "body_ru", :text
  t.column "body_en", :text
  ...
end

然后扩展ActiveRecord::Base类以提供翻译方法：

module Translate

  def self.included(base)
    base.extend ClassMethods
  end

  module ClassMethods
    def translate *columns
      columns.each do |column|
        class_eval <<-EOV
          def #{column}
            unless self.send("#{column}_#{I18n.locale}")
              self.send("#{column}_#{I18n.locale}")
            else
              #{column}_#{I18n.default_locale}
            end
          end
        EOV
      end
    end

  end

end

ActiveRecord::Base.send :include, Translate

之后，从您的模型中调用该方法：

class Article < ActiveRecord::Base
  ...
  translate :title, :body
  ...
end

现在，您可以在不title_ru的情况下修改title_en和globalize3条目。

Answer 2

Globalize3会覆盖following methods，允许您在保存属性时指定区域设置。

product.write_attribute(:title, 'Hows going', locale:'ua')
product.save!

同样适用于read_attribute。由于这是没有记录的，我不确定使用它是否会产生任何不良后果。
