  validates_length_of :username, :in => 6..20

  has_attached_file :background, MyConfig.paperclip_options
	#validates_attachment_content_type :background, :content_type => ['image/jpeg', 'image/gif', 'image/png']
  #validates_attachment_size :background, :less_than => 1.megabytes



any paperclip validators will keep me from saving the model if :background is nil
