pass iframe through sanitize


I want to let users place in textfield an iframe tag from google maps.

Sanitize cuts everything. I want to add some kind of rule to sanitize, so it cuts js, but pass through an iframe from google maps and yandex maps

Tried to place in config config.action_view.sanitized_allowed_tags = %w(‘iframe’) . It didn’t help.


In config/initializers/sanitizer.rb


HTML::WhiteListSanitizer.allowed_tags << 'iframe'
