多个上传Rails Paperclip不保存

I have a rails model 'Guitar' and a rails model 'Photo.' I wanted to be able to attach multiple photos so I watched the railscasts for Paperclip, read the docs, etc. I've used Paperclip in the past to attach a single photo, but I wanted to do multiples this time. I don't have a problem updating the model, and it doesn't error out when I attach sample photos, but when I rails console to Photos.all, nothing comes back. My ultimate goal is to a polymorphic association with an 'Amps' model, but I really just wanted to get 'Guitars' working first.I have a rails model 'Guitar' and a rails model
