ruby-on-rails - 如何在 Rails 的 Action Text 中包含 Pgsearch

Question

我正在将 pgsearch 添加到 Rails 6 Action Text 中，但不确定在 RichText 模型中包含 pgsearch 的最佳技术。我似乎无法在不破坏模型的情况下修补模型。我确实通过完全替换模型来让它工作，但显然不想那样做。任何想法如何使这项工作？这是我目前的模型:

include PgSearch

class ActionText::RichText < ActiveRecord::Base
  self.table_name = "action_text_rich_texts"

  multisearchable :against => :body

  serialize :body, ActionText::Content
  delegate :to_s, :nil?, to: :body

  belongs_to :record, polymorphic: true, touch: true
  has_many_attached :embeds

  before_save do
    self.embeds = body.attachments.map(&:attachable) if body.present?
  end

  def to_plain_text
    body&.to_plain_text.to_s
  end
  delegate :blank?, :empty?, :present?, to: :to_plain_text

end

Answer 1

@dirk-sird-de-vries 的答案对我来说并不是很明显。因此，我将添加一个示例以供我学习和将来引用。

class Book < ApplicationRecord
  include PgSearch

  has_rich_text :chapter

  pg_search_scope :book_search, associated_against: {
    rich_text_chapter: [:body]
  }
end

当您搜索 book.chapter在命令行中，您将获得以下信息:

#<ActionText::RichText id: 1, name: "chapter", body: #<ActionText::Content "<div class=\"trix-conte...">, record_type: "Book", record_id: 1, created_at: "2019-12-31 00:00:00", updated_at: "2019-12-31 00:00:00">

因此， associated_against 需要是 body .
