similar to: saving the user id for thumbnails using attachment_fu

Hi there, I''d like to use RMagick to watermark an image in the tmp directory before Attachment_fu saves it to Amazon S3. I took a look at the callbacks available in attachment_fu. There''s an ''after_attachment_saved'' method but this would be too late, and a ''before_thumbnail_saved'' but this is no good because it''s for thumbnails. I

I am working on a small model mixin called attachment_kung to make attachment_fu polymorphic, so you no longer need a different table and Model class for every associated attachment (Productimage, Ad_doc, etc). All you really need is one model and table to handel all your attachments - in some cases, anyway. I have the code working, but have run into one small hitch that I can''t seem to

I''m trying to modify product images when a user marks a product as "sold" and I am able to modify the original image file successfully, but when I try to reprocess the thumbnails, my ImageMagick modifications don''t stick. Here is what I''ve got going so far: def before_save if self.sold_changed? && self.sold? for photo in self.photos

Basically, I''m trying to crop multiple images out of a remote/original scene.. Think flickr ''tagging'', only, the pixs in the tagged boxes become their own unique images.. by way of simulating an upload from the controller using attachment fu.. can''t quite figure out the specific method in fu that would allow me to do this.. I''m so near the edge right

I just installed attachment_fu and for some reason, it seems to be looking in the wrong location for my images. I have a Product model that belongs to a photo model. the photo model has the attachment_fu installed and configured like so: class Photo < ActiveRecord::Base has_attachment :content_type => :image, #Allow standard image formats :path_prefix

howdy! I had the problem that attachment_fu didn''t make a thumbnail, but everything else worked. I read this post http://www.ruby-forum.com/topic/104213 and added a parent_id column. now I get the following error when I trie to add a photo: undefined method `find_or_initialize_by_thumbnail_and_parent_id'' for Photo:Class my code is: class Photo < ActiveRecord::Base

I have a model using attachment_fu (via has_attachment) and I''m creating thumbnails for the attached images. I have an extra field ''foo'' that I''m validating on create with validates_presence_of :foo. One problem arises when I upload an image: The ''foo'' is not propogating down to the thumbnails. What should I put in my model to grab the

I''m using Attachment_Fu to save several thumbnails of a photo (resizing with ImageMagick) But when I try to crop them, nothing seems to happen to the file I want to drop and no error messages. I check the file timestamp of the thumbnail I want to crop and it looks updated. What''s strange is that ALL the other thumbnails and the original image''s file timestamps are

Hi, I''m having trouble with attachment_fu on windows not generating any thumbnails on the fly. I started out trying to incorporate this into my app without success then tried implementing Mike Clarke''s tutorial (http://www.clarkware.com/cgi/blosxom/2007/02/24) and got the same problem. I have resolved some gotchas I found in the "attachment_fu on Windows" thread

I''ve tried migrating acts_as_attachment to attachment_fu (just to see if I could replace RMagick with ImageScience+FreeImage), but the quality of the thumbnails is just horrendous, blurred beyond recognition (downscaling a 1280x1024 to a few considerably smaller thumbnails). Changing attachment_fu to use RMagick again and the thumbnails were crispy sharp again. I was wondering

hi folks: I follow this article:http://clarkware.com/cgi/blosxom/2007/02/24 all goes well except the public_filename ，it return something like "photos/0000/0001/test.jpg" ,not the expected RESTFUL URL LIKE ''photos/1/test.jpg'',any suggestion? My Env is Rails 1.2.3 on Ruby 1.8.6 with attachment_fu from http ://svn.techno-weenie.net/projects/plugins/attachment_fu/ by now

Hi, I am attempting to replace an exiting photo with a new one uploaded by the user. I am using attachment_fu and I am coming up with the following exception: can''t convert nil into String /vendor/plugins/attachment_fu/lib/technoweenie/attachment_fu/backends/file_system_backend.rb:23:in `join''

Hi, I have an Image model that is attached to a item. The image was uploaded through attachment_fu. Now, I want to reuse the same image for a new item. I tried several tips found online. For example in http://danieloshea.com/articles/254-cloning-images # Create a clone of an image and it''s thumbnails. def create_clone c = self.clone self.thumbnails.each do

Hello friends, I have configured attachment_f. It''s working fine on Local(development) system but giving problem on production. Basically on production the attachment_fu is not able to generate thumbnail image it saving the original size image. Below is the configuration. has_attachment :content_type => :image, :storage => :file_system, :max_size

I have this class: class Logo < ActiveRecord::Base has_one :something has_attachment :content_type => :image, :storage => :db_file, :max_size => 500.kilobytes :thumbnails => {:web => ''150x100'', :pdf => ''150x100''}, :processor =>

It took me a while to figure this out and I don''t see any wiki pages for attachment_fu so I figure I would just post this here. I didn''t like the way attachment_fu by default creates directories under a given directory for a specific class e.g. item_image/1/img_1.jpg item_image/1/img_1_thumb.jpg item_image/2/img_2.jpg item_image/2/img_2_thumb.jpg item_image/3/img_3.jpg

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,

I have a requirement that can''t be that outrageous.... I want to be able to upload an image, and have multiple thumbnails be created for each. Then, I want to post process each image (the main image plus the thumbnails) to add borders. The trick is that the borders need to be different for each image. I thought I could use the after_resize handler, but when I try to add a border to

I followed the instructions on Mike Clark''s weblog and everything works perfectly except the thumbnail column in my DB is alwas NULL. I''m using S3 as my storage system. Anyone else having this issue with thumbnails? has_attachment :content_type => :image, :storage => :s3, :max_size => 500.kilobytes, :resize_to =>
