Hello,
Recently attachment_fu stopped resizing images for me. I''m puzzled
because before today it was resizing them and I don''t know
what''s
changed. Here''s my code:
class Product < ActiveRecord::Base
has_attachment :content_type => :image,
:storage => :file_system,
:max_size => 18.megabytes,
:resize_to => ''300x'',
:thumbnails => { :thumb => ''61x110!''
}
validates_as_attachment
end
I expected a 420x595 image to be resized to 300xWhatever and a 61x110
thumbnail to be created. The image and thumbnail product records
were both created in the database but the images were left at the
original size.
Strangely the width and height fields in the database are no longer
being set. For new uploads they are null whereas previously they had
been set to the measurements of the resized images.
I think I''ve traced the problem to this method (but I could equally
well be barking up the wrong tree):
attachment_fu/processors/rmagick_processor.rb:
module ClassMethods
# Yields a block containing an RMagick Image for the given
binary data.
def with_image(file, &block)
begin
binary_data = file.is_a?(Magick::Image) ? file :
Magick::Image.read(file).first unless !Object.const_defined?(:Magick)
puts "binary_data.nil? : #{binary_data.nil?}"
puts "file.nil?: #{file.nil?}"
puts "const_defined? :
#{Object.const_defined?(:Magick)}"
rescue
# Log the failure to load the image. This should
match ::Magick::ImageMagickError
# but that would cause acts_as_attachment to require
rmagick.
logger.debug("Exception working with image: #{$!}")
binary_data = nil
end
block.call binary_data if block && binary_data
ensure
!binary_data.nil?
end
end
The puts statements give this output:
binary_data.nil? : true
file.nil?: false
const_defined? : false
So it looks like the undefined constant prevents binary_data from
being assigned. But I don''t know what to do about this.
I''d appreciate any help.
Thanks and regards,
Andy Stewart

RMagick does still work for me when I call it from straight Ruby -- which is what I am doing manually to resize images until my problem is fixed. This code looks like: require ''rubygems'' require ''RMagick'' ... img = Magick::Image.read(image_file).first # image_file defined above in snipped code img.change_geometry("300x") do |cols, rows, img| img.resize(cols, rows) end So I think my RMagick installation is still okay.... Thanks for taking the time to reply (and sorry about my double post with slightly different titles...user malfunction!).

Andrew are you devving on win xp? Incase others are finding this problem thought i would mention that Heggie (of heggie.biz) discovered a windows race condition bug with this plugin. He got some of it fixed before we reverted back to acts_as_attachment for artabase.net The problem seems to be with the plugin looking in the file system for the file size, which isn''t available immediately due to win xp taking a few seconds to update it.
