Net::FTPPermError (500 我不会打开到 10.10...... 的连接 (仅到 174.12......)
我有一个 Rails 应用程序部署到 Heroku。我使用 paperclipftp 将文件上传到 ftp 服务器，因为 heroku 没有提供太多文件上传功能。因此，当我尝试上传文件并保存记录时，出现此错误。
Net::FTPPermError (500 I won't open a connection to 10.10...... (only to 174.12........)
我不知道为什么会这样经过一番搜索，我发现 Heroku 不允许主动 FTP 连接，因此尝试通过编辑 paperclipftp 文件来建立被动连接，
我在其初始化块中添加了这一行
@ftp.passive = @ftp_credentials[ 变量 [passive:true] 但它仍然不起作用。
:passive] if @ftp_credentials.has_key?("passive") 并在我的 YAML 配置文件中传递了一个 。 提前致谢。
I have a rails app deployed to heroku. I have used paperclipftp to upload files to an ftp server, as heroku doesn't give much features with file uploading. So when I try to upload a file and save a record, I get this error.
Net::FTPPermError (500 I won't open a connection to 10.10...... (only to 174.12........)
I don't know why this is coming up. After some searching I came to know that Heroku doesn't allow active FTP connections so tried to establish a passive connection by editing the paperclipftp file.
I added this line in its initialize block
@ftp.passive = @ftp_credentials[:passive] if @ftp_credentials.has_key?("passive") and passed a variable [passive:true] in my YAML config file. But still it doesn't work.
Please Help. Thanks in advance.

您找到问题的答案了吗？我面临着完全相同的问题，并且不知道如何绕过这个问题。解决方案可能是使用 Amazon S3 来保存文件。我会朝这个方向检查并通知您。
问候，

编辑（28/03/11）：S3 绝对是一个很棒的解决方案，非常容易设置。最重要的是，如果您没有大量图片要上传，那么它真的很便宜
have you found an answer to your problem ? I'm facing the exact same issue and do not know how to bypass this. A solution could be to use Amazon S3 to save your file. I will check in this direction and let you know.

EDIT (28/03/11): S3 is definitively a great solution, very easy to setup. On top of this it's really cheap if you do not have tons of pictures to upload
