extend ActiveSupport::Concern
- # This +sanitize+ helper will HTML encode all tags and strip all attributes that
- # aren't specifically allowed.
+ # Sanitizes HTML input, stripping all tags and attributes that aren't whitelisted.
#
- # It also strips href/src tags with invalid protocols, like javascript: especially.
- # It does its best to counter any tricks that hackers may use, like throwing in
- # unicode/ascii/hex values to get past the javascript: filters. Check out
- # the extensive test suite.
+ # It also strips href/src attributes with unsafe protocols like
+ # <tt>javascript:</tt>, while also protecting against attempts to use Unicode,
+ # ASCII, and hex character references to work around these protocol filters.
#
- # <%= sanitize @article.body %>
+ # The default sanitizer is Rails::Html::WhiteListSanitizer. See {Rails HTML
+ # Sanitizers}[https://github.com/rails/rails-html-sanitizer] for more information.
#
- # You can add or remove tags/attributes if you want to customize it a bit.
- # See ActionView::Base for full docs on the available options. You can add
- # tags/attributes for single uses of +sanitize+ by passing either the
- # <tt>:attributes</tt> or <tt>:tags</tt> options:
+ # Custom sanitization rules can also be provided.
#
- # Normal Use
- #
- # <%= sanitize @article.body %>

+ # resulting markup is valid or even well-formed. For example, the output may still
+ # contain unescaped characters like <tt><</tt>, <tt>></tt>, or <tt>&</tt>.
#
- # Custom Use - Custom Scrubber
- # (supply a Loofah::Scrubber that does the sanitization)
+ # ==== Options
#
- # scrubber can either wrap a block:
- # scrubber = Loofah::Scrubber.new do |node|
- # node.text = "dawn of cats"
- # end
+ # * <tt>:tags</tt> - An array of allowed tags.

+ # or {Loofah::Scrubber}[https://github.com/flavorjones/loofah] object that
+ # defines custom sanitization rules. A custom scrubber takes precedence over

- # class KittyApocalypse < Loofah::Scrubber
- # def scrub(node)
- # node.text = "dawn of cats"
