“missing required :bucket option” for Paperclip/S3

Question

In my Rails app I\'m letting users upload an image when they create a \"release\", and it should upload directly to S3. I\'m getting the following error in both development and

Answer 1

I think that's because :bucket should be an option passed to Paperclip not to S3.
Fixed config

  config.paperclip_defaults = {
    :storage => :s3,
    :s3_protocol => 'http',
    :bucket => ENV['AWS_BUCKET'],
    :s3_credentials => {
      :access_key_id => ENV['AWS_ACCESS_KEY_ID'],
      :secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
    }
  }

And Paperclip::Storage::S3 doc seems to confirm that, even being so poorly written/formatted.

EDIT:

In one of my projects I use Paperclip with Fog gem and this works well

Paperclip::Attachment.default_options.merge!(
  :storage => :fog,
  :fog_credentials => {
    :provider => 'AWS',
    :aws_access_key_id => ENV['S3_ACCESS_KEY_ID'],
    :aws_secret_access_key => ENV['S3_SECRET_ACCESS_KEY'],
    :region => 'eu-west-1' # in case you need it
  },
  :fog_directory => ENV['S3_BUCKET'], # only one of those is needed but I don't remember which
  :bucket => ENV['S3_BUCKET']
)
