SanitizeField

We want to be able to mix model fields with Sanitize configuration and implement a sanitization in a before_save callback.

An alternative to this plugin might be using a Rails whitelist. This isn't developed, but is an idea on http://wonko.com/post/sanitize

Rails::Initializer.run do |config| config.action_view.white_list_sanitizer = Sanitizer.new config.action_view.sanitized_allowed_tags = ‘table’, ‘tr’, ‘td’ config.action_view.sanitized_allowed_attributes = ‘id’, ‘class’, ‘style’ end

Our approach is finer-grained, and should work better for now at least. There is also talk about an alternative 1.9/nokogiri approach to the Sanitizer gem for more optimal performance. Keeping our eyes open about these issues.

Example

class BasicExample < ActiveRecord::Base sanitize :body, Sanitize::Config::RELAXED end

class Whatever < ActiveRecord::Base sanitize :body, :title, :elements => ['a', 'span'], :attributes => {'a' => ['href', 'title'], 'span' => ['class']}, :protocols => {'a' => {'href' => ['http', 'https', 'mailto']}} end
