Uploading to Rackspace Cloud Files with paperclip and fog - ruby-on-rails-3

Question

Can't figure out how to do this? and couldn't find much help from anywhere else!
I have set up the paperclip and fog like this;
config/initializers/fog.rb
connection = Fog::Storage.new({
:provider => 'Rackspace',
:rackspace_username => '',
:rackspace_api_key => ''
})
environment.rb;
Paperclip::Attachment.default_options.update({
:path => ":attachment/:id/:timestamp_:style.:extension",
:storage => :fog,
:fog_credentials => {
:provider => 'Rackspace',
:rackspace_username => '',
:rackspace_api_key => '',
:persistent => false
},
:fog_directory => '',
:fog_public => true
})
I am using file_field to get an image and then posting it to my controller. This gets me something like this in;
"pic"=>{"image"=>#<ActionDispatch::Http::UploadedFile:0x007f90ac06a6c8 #original_filename="3245-1920x1200.jpg", #content_type="image/jpeg", #headers="Content-Disposition: form-data; name=\"cloth[pic][image]\"; filename=\"3245-1920x1200.jpg\"\r\nContent-Type: image/jpeg\r\n", #tempfile=#<File:/tmp/RackMultipart20130104-5386-103laem>>}
What I can't understand is that how do I go about actually saving this file to cloud files using something like this;
file = directory.files.create(
:key => 'resume.html',
:body => File.open("/path/to/my/resume.html"),
:public => true
)
EDIT
Relevant Models;
class Cloth
include Mongoid::Document
has_many :pics
class Pic
include Mongoid::Document
include Mongoid::Paperclip
belongs_to :cloth
has_mongoid_attached_file :image, :styles => { :medium => "300x300>", :thumb => "100x100>" }
And in the controller this is how I am currently creating pic based on above params;
#cloth = Cloth.new
#cloth.pics.create!(params[:cloth][:pic])

Let's step back and look at the problem from different perspective. Can you see if the following script will upload an image to your container:
require 'fog'
service = Fog::Storage.new({
:provider => 'Rackspace',
:rackspace_username => YOUR_USERNAME,
:rackspace_api_key => YOUR_API_KEY
})
container = service.directories.new(:key => YOUR_CONTAINER_NAME)
container.files.create :key => 'my-pix.jpg', :body => File.open PATH_TO_FILE
Update the uppercase parameters with the appropriate variables and let me know what happens. Hopefully this will help narrow down the problem.

Paperclip and ActiveRecord should automatically handle the file upload for you. Here is a good quick start explaining the process:

If you are still having issues, can you provide me with the relevant controller and model code?
