RAILS - 从URL中删除＃.VvHSzGErLVM

Question

我是Ruby on Rails World的新手。

我正在尝试为我的应用程序设置i18n。我可以按照本指南进行操作：http://guides.rubyonrails.org/i18n.html

问题：当我点击像这样的链接时

<%= link_to image_tag("flags/en.png"), :locale=>'en'%>

该URL附加了某种SessionID：

http://localhost:3000/en#.VvHSzGErLVM

如何避免此#.VvHSzGErLVM出现在网址中？

应用程序控制器

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



  def set_locale
    extracted_locale = params[:locale] || extract_locale_from_accept_language_header

    I18n.locale = (I18n::available_locales.include? extracted_locale.to_sym) ? 
                  extracted_locale : I18n.default_locale
  end

  def extract_locale_from_accept_language_header
    request.env['HTTP_ACCEPT_LANGUAGE'] ? request.env['HTTP_ACCEPT_LANGUAGE'].scan(/^[a-z]{2}/).first : 'pt'
  end

  def default_url_options(options = {})
    { locale: I18n.locale }.merge options
  end

end

路由

Rails.application.routes.draw do
  scope '/(:locale)', locale: /#{I18n.available_locales.join("|")}/ do
    root 'home#index'
  end
end
