Cakephp Security and Sanitize in Views

I have a bunch of data getting passed from controllers to 开发者_JS百科views. Is there a quick way to grab all the data being passed from the controllers, like in AppController beforeRender and do a sanitize->html on that data?

Quick way: App::import('Sanitize'); in the model and sanitize everything in beforeSave

Cake cookbook advises a different way though:

For sanitization against XSS its generally better to save raw HTML in database without modification and sanitize at the time of output/display.
