I''m struggling with a single avatar upload system for a user. I''ve hit brick walls with two different routes, so I''d appreciate pointers on choosing the right solution and fixing it: First attempt: attachment_fu (via this tutorial: http://railsforum.com/viewtopic.php?id=15389 ). However, I can''t get attachment_fu to crop the images, even with the suggestion outlined in this post ; http://brendanlim.com/2007/7/28/crop-images-using-attachment_fu-and-rmagick If I include a ! next to the dimensions (as suggested), RMagick seems to ignore the dimensions and save all the thumbnails as the ''resize'' size. Could it be my version of RMagick? Has attachment_fu been updated to crop images? I have to get cropping working, so this is a show stopper! Second attempt: file_column. The guys from Less Everything have a solution in their LovdByLess app which would work really well. They used the file_column plugin to store an ''icon'' in the users table, and so users can only have one icon, which is exactly what I need in my app (and they have cropping working, too!). However, I''ve tried route, and file_upload is hitting a "No such file or directory" error during the upload process. It''s saving and cropping images to /user/avatar/tmp on the file system - so at least I know the cropping is working this time - but my UsersController is hitting this; "Errno::ENOENT in UsersController#update", "No such file or directory" during the upload process. Attachment_fu seems to be the preferred choice, but the file_column route would, presumably, require less work to enforce the one avatar only restriction.

There is also a new one out there called paperclip. It seems pretty nice and easy to use. Not sure about cropping, but it just calls ImageMagick itself, so it probably wouldn''t be too hard to add that. http://thoughtbot.com/projects/paperclip http://groups.google.com/group/paperclip-plugin/topics http://paperclip.lighthouseapp.com/projects/8794-paperclip/overview --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I''m sure I heard about it in a Rails Envy podcast a little while back - wish I''d remembered. I managed to fix my problem with attachment_fu (and have, for the time being at least, settled on using it for my avatars). It appears that I had to explicitly call the rmagick processor in my has_attachment options (no else seemed to be doing so!). In combination with a very handy tutorial (link below) I managed to get cropped thumbnails working exactly as I wanted; http://stuff-things.net/2008/02/21/quick-and-dirty-cropping-images-with-attachment_fu/ Now I just need to work out the best measures for only allowing single avatars per user. Now I''ve come across paperclip, I''m betting it would be the best option for simply overwriting user avatars each time a user uploads a new one (rather than dealing with deletion and choosing defaults each time). So now I still have an avatars model, avatars table, etc - and Paperclip would make it a whole lot simpler! -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
