Question

我遇到了一个奇怪的问题：我正在使用带有rails 3.0.9的paperclip 2.3.16

我有一个模型上传，其中包含属性照片作为附件has_attached_file :photo,。在客户端，一切似乎都可以。调用Upload create动作并调用@ upload.save方法但返回false。当我查看/ tmp文件时，我看到照片已正确上传和处理（有调整大小和水印处理）但公共/系统目录和数据库中没有任何内容。服务器日志给出：

  CACHE (0.0ms)  SELECT COUNT(*) FROM `uploads` WHERE `uploads`.`uploadtoken` = 'fHTVm09QCxMwn2dKOjIcWca+tFTxgW10'
  SQL (0.1ms)  UNLOCK TABLES

这是上传创建动作的开始

  def create
    #remove orphelin photos
    clean_uploads

    newparams = coerce(params)
    @upload = Upload.new(newparams[:upload])

    logger.debug @upload

    @success= true

    #critical section begin
    lock    
    check_limitation
    logger.debug "=========save begin========" 
    @upload.save    
    logger.debug "=========save end========"

之前我遇到过回形针问题，但至少我在服务器日志上遇到了错误。这一次没什么。怎么调查？

回形针保存失败但没有错误日志
