如何添加iframe到ruby on rails 4.2.6中的sanitized標籤？

我試圖用如何添加iframe到ruby on rails 4.2.6中的sanitized標籤？

config.action_view.sanitized_allowed_tags

我試圖找到什麼標籤都已經使用控制檯允許的iframe添加到santized標籤。

     from /app/bin/rails:8:in `require' 
     from /app/bin/rails:8:in `<main>'

任何想法如何添加它而不忽略其他標籤？由於

請對下面的例子看看：

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

我的應用程序稱爲Tapp，我敢肯定你會在這裏有另外一個名字;）

然後在控制檯：

[[email protected] ~/workspace/tapp]$ rc 
Loading development environment (Rails 4.2.6) 
[1] pry(main)> Tapp::Application.config.action_view[:sanitized_allowed_tags] 
=> ["strong", "em", "a", "br", "iframe"]
