loofah-activerecord¶ ↑

Description¶ ↑

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

Features¶ ↑

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

ActiveRecord Extension #1: Opt-In¶ ↑

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

Loofah::ActiveRecordExtension.html_document
Loofah::ActiveRecordExtension.html_fragment

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

# app/model/post.rb
class Post < ActiveRecord::Base
  html_fragment :body, :scrub => :prune  # scrubs 'body' at before_validation
end

ActiveRecord Extension #2: Opt-Out¶ ↑

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

Loofah::XssFoliate::ClassMethods.xss_foliate
Loofah::XssFoliate::ClassMethods.xss_foliated?

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

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

Requirements¶ ↑

Nokogiri >= 1.3.3
Rails 2.3, 2.2, 2.1, 2.0 or 1.2 (if you’re using the ActiveRecord extensions)

Unsurprisingly:
