similar to: Attachment_fu - watermark tmp file before saved to S3

Hi, I use attachment_fu in one of my apps and recently I''ve realized that udpates are taking too much time. After some debugging I''ve found that attachment_fu is calling after_attachment_saved callback no mather if attachemnt has changed or not. For example this code: after_attachment_saved do |photo| logger.info "after_attachment_saved" end # in console - always

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

Hi all.... Admittedly I''m new to Rails and trying to find my way but I''m having an issue with uploading documents with attachment_fu. I have a form where I''m uploading multiple attachments (using AJAX to add file_filed_tags). That seems to work pretty well. The problem is I can''t seem to get the content_type to work as I would expect. For example, if I use

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

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, 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

Hi Has anyone had success with setting image resolution with Rmagick. I am resizing an uploaded image with Rmagick, problem is it keeps the original images resolution and I want to change it to 72dpi. <<<<<< code example >>>>>>>>>> # these are the various techniques I have tried when and after reading the file, trying any or all of them does

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 working on a photo gallery and I''m using File_column to handle the uploads of the files and create my thumbnails, but does anyone here have any idea how to have a watermark (opaque text maybe) placed over one of the versions? Any ideas on how to go about this would be great. Even if it''s just straight RMagick code, that would be fine too. Thanks in advance for the

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 seems that attachment_fu is a pretty popular plugin (it''s great), but I''ve been having a terrible time trying to figure out an issue when using "update_attributes". I''m storing files on the file system rather than in a database. It seems that when "update_attributes" is called with a new file, upload_data= tries to copy a file that

Hi, I got Image model that has_attachment and belongs_to 2 other models via polymorphic association. The problem is that I''d like to customize has_attachment options (resize image) depending on which model the Image is related to - i.e. if Image belongs to Article it should be resized using different settings than if it belongs to Header. Is there a smart way to do it or do I have to

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

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 =>

Hello, I''m working on an import utility that will match the functionality of uploading an object of a model that uses attachment_fu for thumbnailing, etc. Rather than uploading the file via a form, I want to populate the params[:image][:uploaded_data] with data from a file already on the server''s file system. So far, I''ve been able to copy to an instance of Tempfile

I''m starting on a small rails app and i need to generate a report in pdf format. i''ve generated pdfs before using pdf::writer without much problems, but for this project the company sent me a pdf ''watermark'' (or background template) that they want the report to be printed on.. instead of having them stock a bunch of the template stationary and have that paper

Hi… I want to use grImport to create a watermark on a plot() using the methods Paul Murrell describes here: http://cran.r-project.org/web/packages/grImport/vignettes/import.pdf (page 28). I can essentially reproduce this manually at the R prompt, and independently I can use grid.picture(…) successfully in a R script, but when I attempt to do do this in my script: • • •

Hey, I''m using the attachment_fu plugin to upload images on the file system. To retrieve them I''m using: image = "/home/rajeev/Desktop/logo/logo/public#{icon.public_filename}" which is the same as: "/home/rajeev/Desktop/logo/logo/public/icons/0000/0005/green_nature_on_white.jpg" Have can i do this in a shorter way by using RAILS_ROOT?
