ruby-on-rails - 如何将 iframe 添加到 ruby​​ on rails 4.2.6 中的清理标签？

Question

我正在尝试使用

将 iframe 添加到经过清理的标签中

config.action_view.sanitized_allowed_tags

我试图通过控制台找到哪些标签已经被允许。

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

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

知道如何在不忽略其他标签的情况下添加它吗？谢谢

请看下一个例子:

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

我的应用名为 Tapp，我很确定您在这里会有另一个名字 ;)

然后在控制台中:

[retgoat@iMac-Roman ~/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"]
