== 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)
