Question

I\'m trying to call sanitize within a controller. Here\'s what I tried:

class FooController < ApplicationController
  include ActionView::Hel         


        

Answer 1

you can use this ActionController::Base.helpers inside action method:

class SiteController < ApplicationController
  def index
    render :text => ActionController::Base.helpers.sanitize('<b>bold</b>')
  end
end

Hope this helps

Rails 6:

To strip links (for example) from a text, just call:

...
Rails::Html::LinkSanitizer.new.sanitize("links here will be stripped")
...

I'm not sure what you're trying to do here but I'm almost 100% certain it doesn't belong in the controller.

If you want to sanitize an attribute before you save it to the DB, do so in the model with a before save callback.

Otherwise, sanitize in the view template or view helper.
