to_html()

def to_html
  HtmlConversion.node_to_html(node)

to_plain_text()

将附件转换为纯文本。

attachable = ActiveStorage::Blob.find_by filename: "racecar.jpg"
attachment = ActionText::Attachment.from_attachable(attachable)
attachment.to_plain_text # => "[racecar.jpg]"

如果设置了 caption，则使用它。

attachment = ActionText::Attachment.from_attachable(attachable, caption: "Vroom vroom")
attachment.to_plain_text # => "[Vroom vroom]"

可以通过实现 attachable_plain_text_representation 方法来覆盖呈现方式。

class Person < ApplicationRecord
  include ActionText::Attachable

  def attachable_plain_text_representation
    "[#{name}]"
  end
end

attachable = Person.create! name: "Javan"
attachment = ActionText::Attachment.from_attachable(attachable)
attachment.to_plain_text # => "[Javan]"
