Converts the attachment to plain text.



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



Use the #caption when set:



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



The presentation can be overridden by implementing the attachable_plain_text_representation method:



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]"
