title: How to sanitize data (remove html tags) before saving a record?
body: <p>I was wondering if Rails3 had an easy way to remove html tags from the input data before saving it in the database.</p>
  
  <p>Right now the data is sanitized on the view level by HAML. JS doesn't get executed and stuff, but I'd like to completely remove potentially harmful data.</p>
  
  <p>Basically, my question is: is there a helper I could use in a before_save filter to safely strip the tags out?</p>
