Attachment_Fu and Rails 2,1

In my application, I use mini_magick and I need to convert images to
black and white and sepia tones.  In Rails 1,2,3, this used to work:

  after_resize do |record,img|
        logger.debug "img = #{img}"
        logger.debug "record = #{record}"
        logger.debug "self = #{self}"
        logger.debug "record.thumbnail = #{record.thumbnail}"
        if record.thumbnail.to_s.match(/.*_bw/)
          img.combine_options do |i|
            i.colors("256")
            i.colorspace(:GRAY)
            i.colorspace(:RGB)
            i.quality 100
          end
        end

        if record.thumbnail.to_s.match(/.*sepia/)
          img.combine_options do |i|
            i.colors("256")
            i.colorspace(:GRAY)
            i.colorspace(:RGB)
            i.fill "#cc9933"
            i.colorize "30/30/30"
            i.quality 100
          end
        end

  end

Now that I''m trying to use Rails 2.1, the log file says:

img record = #<MiniMagick::Image:0x20e43ac>
self = Photo



  SQL (0.000471)   ROLLBACK
ApplicationProcessor::on_error: MiniMagick::MiniMagickError rescued:

/Users/matt/Sites/checkout/vendor/plugins/attachment_fu/lib/technoweenie/attachment_fu/processors/mini_magick_processor.rb:21:in
.
.
.

So, it seems that the callback is only getting one argument.  And it''s
getting the mini_magick::Image in the place where it is supposed to get
the record.

I''ve spent quite a bit of time looking at attachment_fu.rb around line
437 (callback_with_args) to try to figure out how this works, and I''m
wondering if anybody else is having any success with attachment_fu and
rails 2.1?  Are you getting both parameters passed to your callback?

Thanks,

Matt

Re: Attachment_Fu and Rails 2,1

I just had this same problem with my app, in your
before_thumbnail_saved method you no longer pass recrd and thumbnail,
only thumbnail. Heres how mine looks now.

  before_thumbnail_saved do |thumbnail|
    record = thumbnail.parent
    thumbnail.user_id = record.user_id
    thumbnail.parent_id = record.id


regards

Re: Attachment_Fu and Rails 2,1

before_thumbnail_saved now does only take one parameter.

But, the docs for after_resize still show that it is supposed to be able 
to take two parameters.  Does the following very basic after_resize 
callback print good results for anybody?  Below is one that will just 
output some information to the log file.

  after_resize do |record,img|
        logger.debug "img = #{img}"
        logger.debug "record = #{record}"
        logger.debug "self = #{self}"
        logger.debug "record.thumbnail = #{record.thumbnail}"
  end

Re: Attachment_Fu and Rails 2,1

I think attachment_fu may have some problem working with Rails 2.0 and 
above.

I use a piece of code from the book Practical Rails Social Networking 
Sites by Alan Bradbune in one of my projects which uses the plugin. It 
works perfectly with Rails 1.2.6 (and any other version a.2.*) but fails 
to work with Rails 2.0.2 and 2.1.2. It just complains "NoMethodError 
(undefined method `callbacks_for'' for #<Photo:0xb4a9a484>)"
