rails gsub,regexp ,match 的应用

1.将 电话号码的中的 '/' '+' 统一替换为 '-'
eg : "010/51248525+110"  --- "010-51248525-110"

domains = Global::Domain.all
domains.each do |domain|
  db_name = Entos::DbConfig.get(Rails.env,domain.orgnization_id)
  ActiveRecord::Base.connection.execute("USE #{db_name}")

  phone_regexp=/\A\d{3,4}-\d{7,8}\z|\A\d{3,4}-\d{7,8}-\d{1,3}\z|\A\d{3,15}\z|\A\d{7,8}-\d{1,3}\z/
  mobile_regexp=/\A\d{11}\z/
  qq_regexp=/\A\d{5,10}\z/
  User.find_each do |user|
    
    unless !user.phone.present?
    user.phone= user.phone.gsub(/\/|\+/,'-') 
    end
    if user.phone.present? and phone_regexp.match(user.phone).nil?
    user.phone=nil
    end
    if user.mobile_phone.present? and     mobile_regexp.match(user.mobile_phone).nil?
    user.mobile_phone=nil
    end
    if user.qq.present? and qq_regexp.match(user.qq).nil?
    user.qq=nil
    end
    user.save
  end
end

2.替换表情符号-- 将mblog 中【pinyin】替换为 【拼音】

domains = Global::Domain.all
domains.each do |domain|
  db_name = Entos::DbConfig.get(Rails.env,domain.orgnization_id)
  ActiveRecord::Base.connection.execute("USE #{db_name}")

  Mblog.find_each do |mblog|
    unless mblog.content.nil?
      mblog.content=mblog.content.gsub(/\[(\w+)\]/) do |c|
        emotions[$1]
      end
      mblog.save
