I see that the SVN version of the excellent file_column plug-in can create thumbnails using the url_for_image_column helper. This uses Rmagick to create the thumbnail... Quick question... Let''s say the file is a TIFF image - can the helper create a JPG version of the thumbnail for display in the browser? Curious if the plug-in can handle that transform with some creative use of the

Hello, Iam providing access to many images on a share to windows users from my linux samba over the internet. The problem is that I need thumbnail viewing because of the nature of this library and thumbnails take to much time to load it seems as though it is actually loading the entire image to then display the small thumbnail. Is this true? Also isnt there some kind of caching that can be

does anyone know much about resizing different versions of images with file_column? i tried it and everything works fine, but my question is can you do more than just make sizes with a version of image? i''m working on a photo album and i would like to resize the image to a medium size, but create a thumbnail as well and crop anything left to make the thumbnail a perfect square. --

Hello guys, I am building a photo website and I have some questions before I really start programming the site. My system will be Debian + lighttpd + mysql +fastcgi + ImageMagick I plan to use file_column for image handling/verification and thumbnail creation. My question is; I need to store images in a place outside of webroot so only registered members can see them. To serve them secure

I was doing some research about creating thumbnail images on the fly after an image has been uploaded in a form, but for some reason it''s not working for me. I''ve downloaded ImageMagick 6.2.5 for Mac but when I run a test (identify image.gif) it gives me this error: dyld: Library not loaded: /sw/lib/libjpeg.62.dylib Referenced from: /Developer/ImageMagick-6.2.5/bin/identify

Has anyone any experiance with the FileColumn plugin. I''m trying to create thumbnails, and also alow non picture uploads. Here''s some working code, but if I try and upload a zip, it says ''File invalid image''. Is there anyway of having both image uploads (and thumbnail generation) while also allowing non image uploads? class Entry < ActiveRecord::Base

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

Quick question: I am going to use the file_column plugin to manage uploading thumbnails. By default the images are stored in the public/ dir of the rails project. The problem I see is that when capistrano redeploys a new build and symlinks it in none of the images will be in the new public/ dir... Does anyone have a solution for this? Thanks, Zack -------------- next part -------------- An

Can anyone point me to a resource for hand coding some sql so I can create my own for the following models: I''m using single table inheritance to store related objects eg: Thumbnail < Image < File :: ActiveRecord:Base Image has_many thumbnails Thumbnail has_one image When I come to list thumbnails I''d like to be able to: 1.

Hi! Uhm are attributes just something like additional members of a class, other than those that come from the names of columns in the table? I''ve got images table, which has ''name'' column. I''ve added support for creating thumbnails out of uploaded pictures and i''d like to have an easy way of accessing them in my views. How to do it? I.e. my image

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,

Howdy. We use the handy file_column plug-in in some of our apps. We have a model with a file field and we upload both images and non-images into this field. It is specified as follows: file_column :file_uri, :magick => {:versions => {:thumbnail => {:size => ''200x''}}} Well, it works great for images but for non-images, the save fails. The root cause is an

The file column plug-in is great, but there is a problem with it. Well, two... But the other is well documented now. :^) Consider a time when you''ve created a CMS for a client and it''s been in use for over a year. Say 1500+ images have been uploaded so far. Now the client comes back with a simple request... ''Can you change the thumbnail size to 80/90, rather than

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

Programs with special uncommon file formats (not jpg) often register a shell extension in Explorer that offers thumbnails for these files (since the files otherwise wouldn't have previews). When I trigger in a Wine application (eg. SketchUp) the File Open dialog, I can see previews of the files (skp files) in the preview panel. This means the shell extension does work in Wine. The Shell

Hi, i was struggling for a function where only 1 thumbnail should be active and others inactive when clicked on the particular thumbnail. code: 1. view: 2. <script type="javascript"> 3. function PlayVideo_options(videoFile, id) { 4. document.getElementById(id).className = ''video_option active_video''; 5. } 6. </script> 7. 8.

Hello, I''m a newbie to Ruby on Rails and like many others, I have been working through the depot application in the Agile Web Development book. I was wondering if anyone had enhanced the depot application to include the upload of images for each product?

I''m using file_column for upload images. now,I want to use the plugin attachment_fu.

Hi, With some help from Quinn_Storm, iXce, maniac103, mikedee and KristianLy :), I've managed to modify switcher.c and make a new plugin: thumbnail.
