Rails - Sep 2009 - Paperclip attachment to AWS - ActiveRecord::AssociationTypeMismatch

Hi,

I have been trying to do this for a few days now and cannot figure it
out. I would be very grateful is anyone can help me

I am trying to upload an attachment to AWS, S3 using paperclip,
however every time I keep getting this error:

 ActiveRecord::AssociationTypeMismatch in
ProjectController#create_notice

Graphic(#37649720) expected, got Tempfile(#27280470)

RAILS_ROOT: C:/devlopment_tools/projects/codex1/active/bugtrigger

The code is:

--Notice Model
 class Notice < ActiveRecord::Base
   has_many :graphics
 end

--Project Controller
 def create_notice
   @notice = Notice.create(params[:notice])
 end

--Form
 <%= form.file_field(:graphic) %>

--Graphic
 class Graphic < ActiveRecord::Base
   belongs_to :notice
   attr_accessor :notice_id
   has_attached_file :graphic,
                     :storage => :s3,
                     :s3_credentials => RAILS_ROOT + "/config/
s3.yml",
                     :path => ":attachment/:id/:style.:extension",
                     :bucket => "attachements"
 end

Thanks!
