Does anyone know of a way to copy files with Paperclip using S3 for storage? Before I try to write my own, I just wanted to make sure there wasn't already a way to do this. Thanks
After some more messing around with paperclip, I figured it out. It's ridiculously simple to copy files!
# Stupid example method that just copies a user's profile pic to another user.
def copy_profile_picture(user_1, user_2)
user_2.picture = user_1.picture
user_2.save # Copied the picture and we're done!
end
This also works great with amazon s3. Sweet
