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

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''

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 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 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

On the creation of a member the member''s picture uploads as it should. However, when updating the member, while selecting a new picture, an error is thrown: can''t convert nil into String RAILS_ROOT: /Users/chris/Documents/Projects/Rails/CommunityCMS/trunk Application Trace | Framework Trace | Full Trace

Hi all. I''ve done a little google search, but doesn''t find anything (with "attachment_fu default path") that could help me in changing attachment_fu''s default path. My model: [audio.rb] has_attachment :max_size => 20.megabytes has_attachment :content_type => "audio/mpeg" has_attachment :storage => :file_system

Hello friends, I have a query like I am using a attchment_fu to store images. But the i don''t want to store to the default path let say :path_prefix => ''public/uploads'' i want a dyname path for e.g :path_prefix => ''public/#{ current_user.id}'', So just wanted to know how can i say images to the dynamic location. Regards Abhishek Shukla

First off, I''m not trying to spec attachment_fu, I know it''s been tested. But, I added some code to that model that I do need to test. Basically, I need to somehow fulfill the "uploaded_data" property so I can actually run my tests(otherwise they fail because of validations). The "uploaded_data" field is what would grab the multipart data from form. Here

I''m using file_column for upload images. now,I want to use the plugin attachment_fu. I have seen that for use it, i must create the attributes like: class CreateMugshots < ActiveRecord::Migration def self.up create_table :mugshots do |t| t.column :parent_id, :integer t.column :content_type, :string t.column :filename, :string t.column :thumbnail,

I am using attachment_fu to create thumbnails, and it is working great. However, I am have a view with all my users thumbnails displayed and am trying to make it so when you click on a thumbnail of their avatar, it shows that users profile. In order to accomplish this I have saved a user_id identifier for each avatar, but the problem is that attachment_fu only saves this user_id for the main

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 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 =>

I just used attachment_fu for the first time, and it works quite well. I have a user-model, and each of them has_one :image (and the images belongs_to :user). I have a question on this though: how can i remove images? Whenever i set a new image for a user (a user who already has an image), then the table with images gets updated correctly, with the user_id column of the old image set to null, and

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,

Retrieving the high 32 bits of a signed multiply is rather annoying. It appears that the simplest way to do this is to compute the absolute value of the arguments, and perform a u32 x u32 -> u64 operation. If the arguments' signs differ, then negate the result. Since there is no u64 support in the cvt instruction, we have the perform the 2's complement negation "by hand".

I am seeing some strange entries in my Apache error log from FCGI that I don''t understand. I have pasted one of the lines below. Anyone seen this or know what might be going on?

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''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, 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
