The code is:

  end

--Project Controller
  def create_notice
    @notice = Notice.create(params[:notice])
  end

--Form
  <%= form.file_field(:graphic) %>

--Graphic
  class Graphic < ActiveRecord::Base
    belongs_to :notice
    attr_accessor :notice_id
    has_attached_file :graphic,
                      :storage => :s3,
                      :s3_credentials => RAILS_ROOT +
"/config/s3.yml",
                      :path => ":attachment/:id/:style.:extension",
                      :bucket => "attachements"
  end

Thanks!
