class QuestionAttachment < ActiveRecord::Base
  belongs_to :question

  has_attachment :content_type => :image,
  :storage => :file_system, 
  :path_prefix => 'public/question_files'

  def sanitize_filename(filename)
    return unless filename
    returning filename.strip do |name| 

      name.gsub! /^[^\.]+/, 'customed filename'
    end
  end
end

直对单个后缀的文件有用，对xxx.tar.gz型文件名需要修改
name.gsub! /^[^\.]+/, 'customed filename'
