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? I have tried
this but no success.
Would appreciate any help.
Thanks
Raj

Hey,
Thanks for that it works perfect. Just got one question. When I run all
3 lines in the console i get:
image = File.join(RAILS_ROOT, ''public'', icon.public_filename)
"script/../config/../config/../public/icons/0000/0005/green_nature_on_white.jpg"
image = File.expand_path(''public'' + icon.public_filename,
RAILS_ROOT)
"/home/rajeev/Desktop/logo/logo/public/icons/0000/0005/green_nature_on_white.jpg"
image = File.join(RAILS_ROOT, "public#{icon.public_filename}")
"script/../config/../config/../public/icons/0000/0005/green_nature_on_white.jpg"
Although they all work I don''t understand what the script/../config....
bit means?
Cheers

It also implies that the current directory is almost certainly the same as RAILS_ROOT because ''..'' means the parent directory so any ''foo/..'' means the foo subdirectory''s parrent -- the current directory. You can generally remove such constructs (there are some oddities that can happen with symbolic links that you can likely ignore in this case). -Rob Rob Biedenharn http://agileconsultingllc.com Rob-xa9cJyRlE0mWcWVYNo9pwxS2lgjeYSpx@public.gmane.org --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
