I am trying to use attachment_fu + image science on jRuby-1.5.2 and Rails 3. I have followed the attachment_fu docs. However, when I upload the form form the browser, i get an error on validate_as_attachment saying size cannot be blank. This is what the log says
size can't be blank translation missing: en.activerecord.errors.messages.inclusion
when I modify the plugin to forget size check or not add validate_as_attachment check, an entry is made in the DB table but the actual file is not transfered.
Can anyone please guide me, Also is there a Rails3 compatible plugin available.
Thanks for the help
