  What's the motivation behind the re-write?

  Note: Only allows 1 attachment per model (as of june 2007). I'm 'bout to hack myself an attachment_fufu...

  I was unable to get the Amazon S3 backend to work properly (in Rails 2).

  If you want more than one attachment per model check out the file_column plugin. It doesn't have S3 support but it allows you to treat a file as just another column type in your database.

  using the callback:
  after_resize do |record, img|
  record.size = img.filesize
  end
  used to work fine with rails 1.2.6

  but I upgraded to 2.1 and get the error message:
  The error occurred while evaluating nil.filesize

  Then I applied the patch from:
  http://blog.methodmissing.com/2008/1/19/edge-callback-refactorings-attachment_fu/

  On the bottom of attachment_fu.rb and I got the error message:
  undefined method `run' for ActiveSupport::Callbacks::Callback:Class

  Please, I need help to fix this.

  Thank you.

  I've been using this plugin with great success but the default error messages suck...

  Pablo - I've got the same problem; can't try it myself yet, but I see Rick Olsen has updated attach_fu back in march for Rails 2.x - he credits methodmissing, but his changes are different (and after all the methodmissing changes are for edge rails not plain vanilla shipping rails).

  That's what I'll be trying next: updating the plugin from techo-weenie.

  Having a problem using Attachment Fu with Single Table Inheritance. Seems like they don't get along too well... keep getting an error "undefined method for "attachmentoptions". This occurs when calling .publicfilename on a model object (ie: content.image.public_filename). Works the first time, but all subsequent attempts result in the error.

  I have the same problem as Pablo. Any chance someone can update the plugin. I have looked in the code but i think i am not good enough to find a solution... :(

  I just downgraded to 2.0.2...

  From Windows, saving to the DB requires some tweaking. See http://epirsch.blogspot.com/2008/01/fixing-attachmentfu-on-windows-like.html

  (The problem was that saving to the DB was not working. Partial info was saved)

  Hi Piers and jm. Just encountered the same problem and found the following patch which with a small amend works on 2.1... http://blog.methodmissing.com/

  Here is the full patch for attribute_fu.rb... def callbackwithargs(method, arg = self) notify(method)

       result = run_callbacks(method, { :object => arg }) { |result, object| result == false }
  
       if result != false && respond_to_without_attributes?(method)
         result = send(method)
       end
  
       return result
     end      
  
     def run_callbacks(kind, options = {}, &block)
       options.reverse_merge!( :object => self )
  

  ActiveSupport::Callbacks.run(self.class.send("#{kind}callbackchain"), options[:object], options, &block)

       self.class.send("#{kind}_callback_chain").run(options[:object], options, &block)
     end

  Hi Rick,

  Love the plugin. Couldn't find a place to submit this bug report, but I get this in my mongrel log file about once a month:

  imagescienceprocessor.rb:14: [BUG] Segmentation fault

  If anyone has any info on this please drop me a line. I have FreeImage 3.9 installed on Ubuntu. Brian

  It looks like this attachment_fu doesn't work with an Oracle DB, because 'size' is a special keyword. This could be handled at the DDL layer by outputing \"size\" in all the SQL, or by changing this plugin's convention to, say, dimension(s). Alas.

  I can't understand why I can't upload a file even if its size is OK; I just added to my model:

  hasattachment :maxsize => 10.megabytes
  validates_as_attachment. I tried to upload a file of 2.8 Mb, when debugging its size waz at 0; WHY?????

  If you don't need the size attribute and are using Oracle (ie - not storing images), then do NOT put the size attribute in the table, and instead fake it in the model with 'attr_accessor :size'

  That hack saved a lot of time for our dev team.

  It's a greatest plugin. Resizing image and creating thumbnails are very easy. simply amazing.

  But if i use the "validates_as_attachment" in model it gives the following error "size is not included in the list". If i eliminate this line from model it works fine in all aspects.
