Description

Imagine we have a book model and chapter model. Both models have attributes that needs to have sanitized html. We use a gem called sanitizer to sanitize the text. Now how would you refactor this code to be more DRY and scalable? Bonus: How would you test this?

Directions:

• Clone the gist
• Modify the code (change these files or add your own)
• Save your modifications as a forked gist
• Respond to the Breezy email with a link to your gist

book.rb

require "sanitize"

class Book < ApplicationRecord
  SANITIZE_CONFIG = Sanitize::Config::BASIC.merge output_encoding: "UTF-8"

  attribute :about_the_book, :string
  
  before_validation :sanitize_html
  
  private
  
  def sanitize_html
    self.about_the_book = Sanitize.fragment about_the_book, SANITIZE_CONFIG
  end
end

chapter.rb

require "sanitize"

class Chapter < ApplicationRecord
  SANITIZE_CONFIG = Sanitize::Config::BASIC.merge output_encoding: "UTF-8"

  attribute :content, :string
  
  before_validation :sanitize_html
  
  private
  
  def sanitize_html
    self.content = Sanitize.fragment content, SANITIZE_CONFIG
  end
end
