重新添加缺失的上传到数据库

支持

我尝试了类似这样的代码：

def add_missing_files_to_uploads
  public_directory = Rails.root.join("public").to_s
  db = RailsMultisite::ConnectionManagement.current_db
  uploads_directory = File.join(public_directory, 'uploads', db).to_s
  # 上传文件和优化后的图片
  missing = 0
  matched = 0
  Dir.glob("#{uploads_directory}/**/*.pdf").each do |file_path|
    sha1 = Upload.generate_digest(file_path)
    url = file_path.split(public_directory, 2)[1]
    if (Upload.where(sha1: sha1).empty? &&
        Upload.where(url: url).empty?)
      puts "MISSING #{file_path}" if DEBUG
      missing += 1
    else
      matched += 1
    end
  end
  puts "MISS: #{missing}. Match #{matched}"
end

看起来是不是有点接近了？我的第一次测试似乎失败了，但我可能哪里弄错了。
