I'm using carrierwave with carrierwave_direct to upload directly to
S3. Everything works fine without post-processing but when I try to do
the post-processing, I get a 403 forbidden error when trying to
execute the code:       self.remote_avatar_url =
avatar.direct_fog_url(:with_path => true)

My full code is:

config:

  CarrierWave.configure do |config|
    config.storage = :fog
    config.fog_directory = S3_CREDENTIALS[:bucket]
    config.fog_public     = false

    config.fog_credentials = {
      :provider => 'AWS',
      :aws_access_key_id => 'xxx',
      :aws_secret_access_key => 'xxx'
    }
  end

avatar_uploader.rb:

class AvatarUploader < CarrierWave::Uploader::Base
   include CarrierWave::RMagick
   include CarrierWaveDirect::Uploader
  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}"
  end
   version :thumb do
     process :resize_to_limit => [50, 50]
   end
end

class ClipsController < ApplicationController
  def index
    if params[:key]
      clip = Clip.new
      clip.attachable_id = key[3]
      clip.attachable_type = "Pmdocument"
      clip.key = params[:key]
#      clip.save
      clip.save_and_process_avatar
    end

class Clip < ActiveRecord::Base
  def save_and_process_avatar(options = {})
    if options[:now] or 1==1
      self.remote_avatar_url = avatar.direct_fog_url(:with_path =>
true)
      save
    else
      Resque.enqueue(AvatarProcessor, attributes)
    end
  en
end

I've been hanging with this for about one day now. So I really need
help... Thanks!
