I am trying to upload attachments to my model using Carrierwave. I am following instructions from this post:
Rails 4 multiple image or file upload using carrierwave
In the PostAttachment class, the instructions say add "mount_uploader:avatar, AvatarUploader" which suggests it is an image file. However, I want to upload files such as pdf, excel, word, ppt, etc... So what do I add to the model instead?
Thanks!
