Sanitize + form_for

Hi,

I am trying to sanitize some bad html tags using sanitize
(Sanitize: A whitelist-based Ruby HTML sanitizer - wonko.com).

I have a basic form:

<% form_for … do |f| %>
<%= Sanitize.clean(f.text_field :title,
Sanitize::Config::RESTRICTED) %>
<% end %>

This is incorrect, could anyone help me out.
Thank you.

Anyone pls?
