Rails Searchkick / Elasticsearch has_many和belongs_to关联 [英] Rails Searchkick / Elasticsearch has_many and belongs_to associations

问题描述

我试图使用Searchkick来运行搜索并基于多个模型返回。

Im trying to use Searchkick to run a search and return based on multiple models.

我的图书模型包含这个

class Book < ActiveRecord::Base

  searchkick

  has_many :book_subjects
  has_many :subjects, through: :book_subjects

  belongs_to :author
  belongs_to :publisher

end

然后我的控制器有这个

and then my controller has this

def index

 if params[:search].present?
   @books = Book.search(params[:search], operator: "or")
 else
  @books = Book.all
 end
end

我希望搜索结果搜索相关模型，并返回任何结果 - 所以boo主题名称，作者和发行人。

I want the search results to search the associated models and return any results there too -- so the boo subject name, the author and the publisher.

谢谢

推荐答案

在您的图书模型中，您需要有一个 search_data 块用于索引。

In your Book model you need to have a search_data block for the indexing.

def search_data
  attributes.merge(
    author_name: author(&:name)
    publisher_name: publisher(&:name)
    subjects_name: subjects.map(&:name)
  )
end

这将添加关联到您的索引。

this will add the associations to your index.

您可以使用 .map 方法为 has_many 协会。

You use the .map method for the has_many associations.
