ruby-on-rails 无法使用rails 6 actiontext渲染youtube embed iframe

我已经设置了一个自定义嵌入模型，这样我就可以在我的网站上添加Instagram或youtube嵌入到actiontext内容中。它可以正常工作Instagram嵌入，但不能youtube。
作为参考，我想显示的youtube嵌入代码是：

<iframe width="560" height="315" src="https://www.youtube.com/embed/F0kgw25zjpc" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>

字符串
models/recipe.rb：

class Recipe < ApplicationRecord
  has_rich_text :body
  ...
end

型
models/embed.rb：

class Embed < ApplicationRecord
  include ActionText::Attachable

  validates :content, presence: true # content is text in db
end

型
embeds/_embed.html.erb：

<div class="text-center">
  <div class="d-inline-block h-100">
    <%= embed.content.html_safe %>
  </div>
</div>

型
views/recipes.show.html.erb（我试图在其中实际显示内容- @recipe.body是actiontext）：

<h1><%= @recipe.title %></h1>
<%= @recipe.body %>

型
我可以看到youtube嵌入编辑内容时（它显示在编辑器），但当查看渲染的内容，什么都没有-我可以看到周围的div，所以我知道它被添加到页面，但没有iFrame。
这很烦人，因为Instagram嵌入工作正常-作为参考，Instagram嵌入看起来像：

我有一种感觉，这是iframe相关的，因为更改embeds/_embed.html.erb为：

<iframe width="560" height="315" src="https://www.youtube.com/embed/F0kgw25zjpc" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>

好了，我已经解决了这个问题。正如我所怀疑的那样，这是一个iframe（或者更具体地说是一个非白名单标签）的问题，与Rails清理有关，而不是专门的文本渲染。
解决方案是将iframe附加到白名单标签中，如下所示：
config/initializers/html_sanitation.rb：

Rails::Html::WhiteListSanitizer.allowed_tags << "iframe"

在config/application.rb中，添加以下内容：

class Application < Rails::Application
  # ...

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

字符串
