Chris, I see you already referred to the problem of embedding Youtube videos in actiontext
https://github.com/excid3/cfps/blob/3bed21b7aa319ce8e0a98283965ab64df2597488/2020-railsconf.md

Did you manage to solve the problem?

Hi ya na,

He did a whole talk about this.

You can embed iframes into ActionText but you have to whitelist the iframe element.

##application.rb

config.to_prepare do
  ActionText::ContentHelper.allowed_tags << "iframe"
end

for some reason it does not work for me :(
