CarrierWave拥有令人惊叹的文档,直到您需要在没有模型的情况下完成它!

我设置了我的上传器和雾设置,并且在模型上使用已安装的上传器时它们都能正常工作,但现在我想在没有模型的情况下完成它.

我有这个:

 uploader = CsvUploader.new
 something = uploader.store!(File.read(file_path))
 uploader.retrieve_from_store!(self.file_name)

当我打电话给.store!代码立即运行,这很奇怪,因为上传文件需要几秒钟？

然后我打电话给.retrieve_from_store!上传器对象具有所有正确的S3信息,如完整的URL和内容.

但是,致电:

uploader.file.exists?

返回false.浏览s3网址会从s3返回一个未找到密钥的错误.

那么,我做错了什么？重申一下,它在安装时有效,所以我不认为这是我的雾设置.

我的上传者:

class CsvUploader < CarrierWave::Uploader::Base
  # Choose what kind of storage to use for this uploader:
  storage :fog

  # Override the directory where uploaded files will be stored.
  # This is a sensible default for uploaders that are meant to be mounted:
  include CarrierWave::MimeTypes
  process :set_content_type

  def store_dir
    "uploads/public/extranet_csvs"
  end

  def cache_dir
    "/tmp/uploads"
  end

  # Add a white list of extensions which are allowed …
