Rails 4: html_safe for only specific tags

Question

I want to allow a couple specific tags like (<br>) but let rails continue to escape others. Html_safe does not appear to take any arguments. What's the smoothest way to do this?

Answer 1

The sanitize helper will html encode all tags and strip all attributes that aren’t specifically allowed.

sanitize @article.body, :tags => %w(br)
