Usage

Architecture to store uploaded files (cancan integration):

class Asset < ActiveRecord::Base
  include Uploader::Asset
  
  def uploader_create(params, request = nil)
    ability = Ability.new(request.env['warden'].user)
    
    if ability.can? :create, self
      self.user = request.env['warden'].user
      super
    else
      errors.add(:id, :access_denied)
    end
  end
  
  def uploader_destroy(params, request = nil)
    ability = Ability.new(request.env['warden'].user)
    
    if ability.can? :delete, self
      super
    else
      errors.add(:id, :access_denied)
    end
  end
end

class Picture < Asset
  mount_uploader :data, PictureUploader
  
  validates_integrity_of :data
  validates_filesize_of :data, :maximum => 2.megabytes.to_i
end

For example user has one picture:

class User < ActiveRecord::Base
  has_one :picture, :as => :assetable, :dependent => :destroy
  
  fileuploads :picture
end

Find asset by foreign key or guid:

@user.fileupload_asset(:picture)
