ArgumentError in SongsController#create missing required :bucket option - ruby-on-rails

Question

I've been trying to get paperclip working with amazon s3 all day and I'm gettin' pretty close.
Albeit, how do I get around this error? I've included the bucket in the song model so I'm not sure what it's asking for. Once this is solved it should work.
Error:

Answer 1

In dev and prod env you call:
ENV['my bucketname']
In model:
ENV['bucketname']
Also a good name for env variable would be:
ENV['MY_BUCKETNAME']
In your case:
ENV['AWS_BUCKET']
config.paperclip_defaults = {
:storage => :s3,
:bucket => ENV['BUCKETNAME'],
:s3_credentials => { :access_key_id => ENV['my access key'], :secret_access_key => ENV['my secret access key'] } }
