使用带有carrierwave gem的多个S3存储桶

Question

I have just recently setup my rails 3.2 app to use the carrierwave gem and upload files to S3. What I don't see is the ability to use a different bucket per uploader. Does anyone know if this is a possiblity?

Answer 1

The bucket is specified via the fog_directory config. This configuration option is defined on the uploader and could simply be overwritten with your own method.

Just add the following to your uploader:

def fog_directory
  # your bucket name here
end

Answer 2

The carrierwave wiki explains how to use a separate s3 bucket for each uploader :

def initialize(*)
  super

  self.fog_credentials = {
    :provider               => 'AWS',              # required
    :aws_access_key_id      => 'YOURAWSKEYID',     # required
    :aws_secret_access_key  => 'YOURAWSSECRET',    # required
  }
  self.fog_directory = "YOURBUCKET"
end

Answer 3

Multiple buckets is not currently supported by CarrierWave. You can separate files between uploaders by adding prefixes (folders) to the store_dir . Pull requests are welcome though if this is something you'd like to work on!
