Sanitizable is a Ruby gem that provides a simple way to perform HTML sanitization on attributes in ActiveRecord models.

Add this line to your application's Gemfile:

gem 'sanitizable'

And then execute:

bundle install

Or install it yourself as:

gem install sanitizable

To use Sanitizable in your ActiveRecord model, simply include the Sanitizable module and call the sanitizable class method to specify the attributes to sanitize.

class MyModel < ActiveRecord::Base
  include Sanitizable
  sanitizable :attribute_1, :attribute_2
end

This will automatically sanitize the specified attributes whenever the model is saved. Here is an example sanitization :

my_object.attribute_1 = "<b>Bold</b> no more!  <a href='more.html'>See more here</a>..."
my_object.save

my_object.attribute_1
# => Bold no more!  See more here..
