不在Rails 3.1.3中设置默认语言环境

Question

没有在Rails 3.1.3中设置default_locale

application.rb中:

config.i18n.default_locale = :en

我有3个语言环境(en,es和ca)当我去我的控制台时:

I18n.locale => :ca # I guess the first one in the array

我正在使用Gettext.有人知道它可能是什么？

Answer 1

您是否取消注释以下行？

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

Rails将仅从此位置获取翻译文本.但这是针对Rails特定的翻译宝石.如果要为gettext设置默认语言环境,则需要进行如下设置

将其添加到environment.rb

I18n.supported_locales = Dir[File.join(RAILS_ROOT, "locale/*")].collect{|v| File.basename(v)}

在rails控制台中测试

 ::I18n.locale = 'en'

您可以通过以下gettext方法验证这一点

GetText.locale.to_s

基本上我通过设置I18n.locale = 'en'或任何其他语言环境设置语言.您也可以根据浏览器首选语言设置默认语言.您也可以通过传递lang ='ca'等强制语言在(gettext)中设置语言环境.您只需要使用:before_filter.在该过滤器中调用以下方法

def set_default_language
    languages   = get_browser_preferred_languages_hash(request.env["HTTP_ACCEPT_LANGUAGE"])
    @locale     = languages.blank? ? 'en' : app_preferred_language(languages, params[:lang])[0..1]
    I18n.locale = @locale || 'en'
end

  def get_browser_preferred_languages_hash(languages)
    # no language accepted
    return [] if languages.blank?
    # parse Accept-Language
    accepted = languages.split(",")
    accepted = accepted.map { |l| l.strip[0..1]}
  end

  def app_preferred_language(languages,forced_lang)
    unless forced_lang.blank?
      return forced_lang.class == Array ? forced_lang[0] : forced_lang       
    end
    return 'en' if languages.blank?
    @matched_lang = ''
    languages.each do |lang|
      @matched_lang = support_languages_hash.values.detect{|ele| ele[0..1] == lang}
      break if !@matched_lang.blank?
    end
    return @matched_lang.blank? ? 'en' : @matched_lang
  end

  def support_languages_hash
    GetText.locale
    { _('English')    => 'en-US',
      _('Spanish')    => 'es-419',
      _('Catalan')    => 'ca' }
  end
