ruby-on-rails - 如何设置 elasticsearch-rails 非规范化映射

我正在尝试为 Elasticsearch 非规范化设置映射,如 this link 中的映射。

我有以下型号:

品牌

class Brand < ApplicationRecord
include Elasticsearch::Model

# title

has_and_belongs_to_many :products

index_name Rails.application.engine_name.split('_').first

mapping do
indexes :title, type: 'keyword'
end
end

分类
class Category < ApplicationRecord
include Elasticsearch::Model

# title

has_many :categorizations
has_many :products, through: :categorizations

index_name Rails.application.engine_name.split('_').first

mapping do
indexes :title, type: 'keyword'
end
end

产品
class Product < ApplicationRecord
include Elasticsearch::Model

# title
# description

has_many :categorizations
has_many :categories, through: :categorizations
has_many :variations
has_and_belongs_to_many :brands

index_name Rails.application.engine_name.split('_').first

mapping do
indexes :id
indexes :title
indexes :description

indexes :brands, type: 'keyword'
indexes :categories, type: 'keyword'

indexes :variations do
indexes :price, index: :not_analyzed
indexes :color, index: :not_analyzed
indexes :size, index: :not_analyzed
end
end


after_commit lambda { __elasticsearch__.index_document }, on: :create
after_commit lambda { __elasticsearch__.update_document }, on: :update
after_commit lambda { __elasticsearch__.delete_document }, on: :destroy
end

变化
class Variation < ApplicationRecord
include Elasticsearch::Model

# price
# color
# size

belongs_to :product

index_name Rails.application.engine_name.split('_').first

mapping do
indexes :price, index: :not_analyzed
indexes :color, index: :not_analyzed
indexes :size, index: :not_analyzed
end
end

可搜索模块
module Searchable
INDEX_NAME = Rails.application.engine_name.split('_').first

def create_index!(options={})
client = Product.__elasticsearch__.client
client.indices.delete index: INDEX_NAME rescue nil if options[:force]

settings = Product.settings.to_hash.merge Variation.settings.to_hash.merge Brand.settings.to_hash.merge Category.settings.to_hash
mappings = Product.settings.to_hash.merge Variation.mappings.to_hash.merge Brand.mappings.to_hash.merge Category.mappings.to_hash

client.indices.create index: INDEX_NAME,
body: {
settings: settings.to_hash,
mappings: mappings.to_hash
}
end

def setup
Searchable.create_index! force: true
Product.__elasticsearch__.refresh_index!
end

extend self
end

当我运行它时,它从 30,000 种产品中有 200 种没有分类。我哪里错了?

最佳答案

我得到了它

用户

class User < ApplicationRecord
include Elasticsearch::Model
has_and_belongs_to_many :blogposts, touch: true

index_name 'blog'

mapping do
indexes :name
indexes :email
end

after_commit lambda { __elasticsearch__.index_document }, on: :create
after_touch lambda { __elasticsearch__.index_document }, on: :touch
after_commit lambda { __elasticsearch__.update_document }, on: :update
after_commit lambda { __elasticsearch__.delete_document }, on: :destroy
end

博文
class Blogpost < ApplicationRecord
include Elasticsearch::Model
has_and_belongs_to_many :user, touch: true

index_name 'blog'

mapping do
indexes :title
indexes :body

indexes :user do
indexes :id, type: 'long'
indexes :name, type: 'string' do
indexes :raw, type: 'keyword', index: 'not_analyzed'
end
end
end

def as_indexed_json(options={})
hash = self.as_json()
hash['user.id'] = self.user.first.id
hash['user.name'] = self.user.first.name
hash
end


after_commit lambda { __elasticsearch__.index_document }, on: :create
after_touch lambda { __elasticsearch__.index_document }, on: :touch
after_commit lambda { __elasticsearch__.update_document }, on: :update
after_commit lambda { __elasticsearch__.delete_document }, on: :destroy
end

可搜索模块
模块可搜索
INDEX_NAME = '博客'
  def create_index!(options={})
client = User.__elasticsearch__.client
client.indices.delete index: INDEX_NAME rescue nil if options[:force]

settings = User.settings.to_hash.merge Blogpost.settings.to_hash
mappings = User.mappings.to_hash.merge Blogpost.mappings.to_hash

client.indices.create index: INDEX_NAME,
body: {
settings: settings.to_hash,
mappings: mappings.to_hash }
end

def setup
Searchable.create_index! force: true

10.times do
n = Faker::Name.name
u = User.create name: n,
email: Faker::Internet.free_email(n.split(' ').last)

rand(1..10).times do
s = Faker::Lorem.sentence
u.blogposts.create title: s.split(' ').first, body: s
end
end

User.__elasticsearch__.refresh_index!
end

extend self
end
