CarrierWave / Fog / S3 - "Not a recognized storage vendor"

Using Heroku in production, I have image uploads working fine, rendering thin views. Although, now I am trying to print the filename as part of the url and return the error Is not a recognized storage provider

to the code 'LOGO' => "https://wifiuploads.s3.amazonaws.com/uploads/user/logourl/#{user.id}/#{user.logourl.file.filename}",

- my presumption is that it is present user.logourl.file.filename

since this is the image upload column in my user model. All I am trying to do is print the filename in the url.

My s3.rb config:

CarrierWave.configure do |config|
  config.fog_credentials = {
    :provider               => 'aws',
    :aws_access_key_id      => ENV['S3_KEY'],
    :aws_secret_access_key  => ENV['S3_SECRET'],
    :region => ENV['S3_REGION']
  }
  config.fog_directory = ENV['S3_BUCKET']
end

      

        
        
        
      

    

My loaders / image_uploader.rb

# encoding: utf-8

class ImageUploader < CarrierWave::Uploader::Base

  # Include RMagick or MiniMagick support:
  # include CarrierWave::RMagick
  include CarrierWave::MiniMagick

  # Choose what kind of storage to use for this uploader:
  # storage :file

  storage :fog

  # Override the directory where uploaded files will be stored.
  # This is a sensible default for uploaders that are meant to be mounted:
  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

      

        
        
        
      

    

Gems need to be updated as I haven't specified a specific version. The gems are as follows:

gem "carrierwave" #image receiving
gem "mini_magick" #image processing
gem "fog" #s3 integration

      

        
        
        
      

    

Any thoughts? Let me know if there is any other information I need to provide.
