Status

Description

loofah-activerecord extends loofah's HTML sanitization into Rails ActiveRecord models.

See more about loofah at: http://github.com/flavorjones/loofah

Features

There are two ActiveRecord extensions included with loofah-activerecord:

• Loofah::ActiveRecordExtension is an opt-in sanitizer. You must explicitly declare attributes to be sanitized.
• Loofah::XssFoliate, a drop-in replacement for XssTerminate, is an opt-out sanitizer. By default all models and attributes are sanitized.

ActiveRecord Extension #1: Opt-In

See Loofah::ActiveRecordExtension for full documentation. The class methods mixed into ActiveRecord are:

• html_document
• html_fragment

which are used to declare how specific string and text attributes should be scrubbed during before_validation.

# app/model/post.rb
class Post < ActiveRecord::Base
  html_fragment :body, :scrub => :prune  # scrubs `body` using the :prune scrubber
end

ActiveRecord Extension #2: Opt-Out

See Loofah::XssFoliate::ClassMethods for more documentation. The class methods mixed into ActiveRecord are:

• xss_foliate
• xss_foliated?

which are used to declare how specific string and text attributes should be scrubbed during before_validation.

Attributes are scrubbed with the :strip scrubber by default, unless another scrubber is specified or the attribute is present in an :except clause.

Requirements
