Rails - Mar 2008 - 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
