strip_tags

Importance_2
Ruby on Rails latest stable (v2.3.4) - 1 note - Class: ActionView::Helpers::SanitizeHelper
strip_tags(html) public

Strips all HTML tags from the html, including comments. This uses the html-scanner tokenizer and so its HTML parsing ability is limited by that of html-scanner.

Examples

  strip_tags("Strip <i>these</i> tags!")
  # => Strip these tags!

  strip_tags("<b>Bold</b> no more!  <a href='more.html'>See more here</a>...")
  # => Bold no more!  See more here...

  strip_tags("<div id='top-bar'>Welcome to my website!</div>")
  # => Welcome to my website!

strip_tags method not functioning in controllers, models, or libs

It comes up with an error about white_list_sanitizer undefined in the class you’re using it in. To get around this, use: 

  ActionController::Base.helpers.strip_tags('string')

To shorten this, add something like this in an initializer: 

  class String
    def strip_tags
      ActionController::Base.helpers.strip_tags(self)
    end
  end

then call it with: 

  'string'.strip_tags
