party_mover

Move your content uploaded by CarrierWave from one server to another

Usage

Imagine you have User class with avatar:

class User < ActiveRecord::Base
  # ...
  mount_uploader :avatar, AvatarUploader 
end

And the next AvatarUploader configured for Amazon S3:

class AvatarUploader < CarrierWave::Uploader::Base
  storage :aws
  # ...
end

Create another AnotherAvatarUploader configured for another server:

class AnotherAvatarUploader < CarrierWave::Uploader::Base
  storage :fog

  def initialize(*)
    super
    self.fog_credentials = {
      :provider               => "YOUR_PROVIDER",
      :openstack_auth_url     => "YOUR_AUTH_URL",
      :openstack_username      => "YOUR_USERNAME",
      :openstack_api_key  => "YOUR_API_KEY",
    }
    self.fog_directory = "YOUR_DIRECTORY"
  end
end

And move your avatars with PartyMover:

PartyMover.move!(AnotherAvatarUploader, :avatar, User.all)

After that just reconfigure your AvatarUploader for new server or change your User model in this way:

class User < ActiveRecord::Base
  # ...
  mount_uploader :avatar, AnotherAvatarUploader 
end
