Rails - Jul 2007 - attachment_fu undefined method `upload_data='

Uh, I''m kind of trying to follow the Mike Clark tutorial on
attachment_fu but uh, seems it is incomplete...
I get this error on submitting the form with upload
undefined method `upload_data=''

What''s that?
Where do I define that? I''m guessing in the model file, but what do I
define it as?!

Also, in the model file,
has_attachment options list
:processor => Rmagick
doesn''t work, as a symbol or with quotes around Rmagick.
What is the expected syntax here?


Thanks for any help.
(yes I''ve kind of given up on my own uploads for now... but not
forever, I''ll break out of plugins quick as I can)

uploaded_data is the attachment_fu method that deals with the uploaded
file. You shouldn''t have to define it - you just need to have your
model configured correctly

You do need quotes around Rmagick. What is your actual model code -
options and list look like placeholders. My suspicion is that your
has_attachment configuration line has a syntax error and so
attachment_fu is not getting invoked to deal with the
file.

class Mugshot < ActiveRecord::Base

  has_attachment  :content_type => :image,
                  :storage => :file_system,
                  :max_size => 500.kilobytes,
                  :resize_to => ''300x300>'',
                  :thumbnails => {  :thumb =>
''100x100>'' }

  validates_as_attachment

end


---this should be fine! I only have ImageMagick and RMagick installed,
none of the others. With or without the :processor =>
''Rmagick''
Still error!

my schema:


ActiveRecord::Schema.define(:version => 1) do

  create_table "mugshots", :force => true do |t|
    t.column "parent_id",    :integer
    t.column "content_type", :string
    t.column "filename",     :string
    t.column "thumbnail",    :string
    t.column "size",         :integer
    t.column "width",        :integer
    t.column "height",       :integer
  end

end



--My controller:



class MugshotController < ApplicationController

  def new
    @mugshot = Mugshot.new
  end

  def create
    @mugshot = Mugshot.new(params[:mugshot])

    if @mugshot.save
      flash[:notice] = "Mugshot was successfully created."
      redirect_to mugshot_url(@mugshot)
    else
      render :action => ''new''
    end
  end
end


I don''t get it. The Mike Clark tutorial gets all these raves from lots
of people. It''s ok, missing some details perhaps, but doesn''t
seem to
work for me.

Does anybody have any code samples of working attachment_fu ?
Any other tutorials than the Mike Clark page?

That code all looks good.  How about your view code?  I notice that  
the subject of this thread mentions "upload_data=" when the actual  
method is "uploaded_data=".
