Hey Guys, I need to build an image upload and resize script. I tried file_column, but you can''t rename the uploaded files with it and every time I try to output an image i get... <img alt="Dog" src="/image/file_name/20/thumb/dog.jpg?1165184726" /> Can you see the numbers at the end of the file name? I have no idea where they come from! So, I''ve been trying to adapt this script for my needs... http://railsforum.com/viewtopic.php?id=962 It does pretty much what I need it to do, and it works just fine if I have a model called ''product''. When I try and use it on a model called ''photo'' I just can''t get it to work. I went through the script and every time it mentioned ''product'' i just replaced it with ''photo''. Is there anything else I would have to do? Here is what I''m trying to do... * Upload image to file system * Rename image to a unique filename * Resize image to 3 different sizes * Create a folder (if it does not exist). Folder name session[:user_id] * Store images in the correct users folder * Store the file names into the ''photos'' table * Store the current users id (taken from session[:user_id]) into the ''photos'' table in the ''user_id'' column This must be a pretty common task, yet I can''t seem to be able to find any information on it and it''s driving me slightly crazy! Any help would be very much appreciated.

I like file_column... I use it all the time... but what would you rename the files to? The numbers on the end of the filenameare there because Rails puts them there. Those numbers help ensure that your browser doesn''t cache the image. The numbers are based off of the last modified date of the image... so it will cache until the image changes on disk.

Thanks for the explanation with regards to the numbers at the end of the filename. I want to store images in folders which are named after the user id of the user uploading photos. It just seems more logical than creating a new folder for every single image. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I see where you''re going.... but my advice would be to leave it an move on. It may not be the URL you want, but is that really necessary? I''d take the tradeoff instead of reinventing the wheel. In a few weeks if you really want to change it you could actually change where file_column stores the images... you could then make your own method that uses send_data. That''s how you''d do secure downloads, for example. you could also look into file_column a bit, you''ll see where the naming takes place. It could be a neat little excercise for you to add an option that modifies where the record is saved. With some Ruby-fu, it could be simple. Best of luck!
