Subject: [Rails] attachment\_fu :uploaded\_data

Hi.  
In my Model DesignThumbnail I use Attachment\_fu.

## ----------------- Model ------------------------------- class DesignThumbnail \< ActiveRecord::Base has\_attachment :content\_type =\> :image, :storage =\> :file\_system, :max\_size =\> 150.kilobytes, :resize\_to =\> ‘86x170\>’ validates\_as\_attachment … end

Instead of uploading the image with a form I want to use a stored image.

----------------- Controller -----------  
@thumb = DesignThumbnail.new  
@thumb.uploaded\_data =  
File.open(“#{RAILS\_ROOT}/public/images/sample.jpg”)

## if @thumb.save flash[:notice] = ‘Image was successfully created.’ redirect\_to … else render … end

I receive the error message  
“undefined method `size’ for #\<File:0x2aaaacf79118\>”

vendor/plugins/attachment\_fu/lib/technoweenie/attachment\_fu.rb:288:in  
`uploaded\_data=’  
…

## thanks Michael

Mark,

I had the same issue with ‘Size’ and I tried the patch from the url  
that you posted. It works fine. But if i try to upload a file  
with .JPG (note the uppercase extension), i still get an error  
“Content type is not included in the list”. I tried including the  
extension in the plugin but still did not work.

Is there any work around to fix this.

Thanks
