How to add iframe to sanitized tags in ruby on rails 4.2.6?

I am trying to add iframe to santized tags by using 

config.action_view.sanitized_allowed_tags

I tried to find what tags are already allowed by using the console.

uraai@raiuorial:~/workspace/corse (master) $ heroku run rails c
Running rails c on ⬢ fa4... up, run.9396
Loading production environment (Rails 4.2.6)
irb(main):001:0> puts helper.sanitized_allowed_tags.to_a
NoMethodError: undefined method `sanitized_allowed_tags' for #<ActionView::Base:0x007f18ea91ea60>
        from /app/vendor/bundle/ruby/2.3.0/gems/metamagic-3.1.7/lib/metamagic/view_helper.rb:30:in `method_missing'

        from /app/bin/rails:8:in `require'
        from /app/bin/rails:8:in `<main>'
irb(main):002:0>

Any idea how to add it without ignoring the other tags? Thanks

Please have a look on the next example:

module Tapp
  class Application < Rails::Application
    # In config/application.rb
    config.action_view.sanitized_allowed_tags = ['strong', 'em', 'a', 'br', 'iframe']
  # ...
end

My app called Tapp, I'm pretty sure you will have another name here ;)

Then in the console:

[retgoat@iMac-Roman ~/workspace/tapp]$ rc

[1] pry(main)> Tapp::Application.config.action_view[:sanitized_allowed_tags]
=> ["strong", "em", "a", "br", "iframe"]
