Hi:

I have moved from using attachment\_fu with files stored in the DB to  
Paperclip using S3. The trick now is to migrate the files from the DB  
to S3.

I have tried a few methods like:

SThreeFile.create(:file =\> AttachmentFuFile.first.data)

and

@attachment = AttachmentFuFile.first  
SThreeFile.create(:file =\> ActionController::Streaming.send\_data  
@attachment.data, :filename =\> @attachment.name, :type =\>  
@attachment.content\_type)

The first gives lots of output to the console but doesn’t produce and  
results. The second gives:  
NoMethodError: undefined method `send\_data’ for  
ActionController::Streaming:Module

Can anyone point me in the right direction?

Thanks!
