Question

我已经在docker中安装了Elasticsearch。我得到了像这样的弹性搜索的响应-

curl -XGET http://localhost:9200
{
    "name" : "NXgYHOl",
    "cluster_name" : "docker-cluster",
    "cluster_uuid" : "_na_",
    "version" : {
        "number" : "6.6.0",
        "build_flavor" : "default",
        "build_type" : "tar",
        "build_hash" : "a9861f4",
        "build_date" : "2019-01-24T11:27:09.439740Z",
        "build_snapshot" : false,
        "lucene_version" : "7.6.0",
        "minimum_wire_compatibility_version" : "5.6.0",
        "minimum_index_compatibility_version" : "5.0.0"
    },
    "tagline" : "You Know, for Search"
}

然后，我在rails项目中对其进行配置。

宝石文件

  gem 'elasticsearch-model'
  gem 'elasticsearch-rails'

应用/模型

require 'elasticsearch/model'

class Movie < ApplicationRecord
    include Elasticsearch::Model
    include Elasticsearch::Model::Callbacks
end
Movie.import(force: true)

config / initilizers / elasticsearch.rb

config = {
    host: "http://localhost:9200",
    transport_options: {
      request: { timeout: 5 }
    }
}

if File.exists?("config/elasticsearch.yml")
    config.merge!(YAML.load_file("config/elasticsearch.yml")[Rails.env].symbolize_keys)
end

Elasticsearch::Model.client = Elasticsearch::Client.new(config)

config / elasticsearch.yml

development: &default
    host: 'http://localhost:9200'
    transport_options:
      request:
        timeout: !!integer 300
test:
    <<: *default
production:
    host: 'http://localhost:9200'
  transport_options:
    request:
        timeout: !!integer 300

出现错误：

未定义的方法“ params_encoder”，用于{“ timeout” => 300，：proxy => nil}：哈希

我不明白此错误。

根据红宝石宝石的official docs，看来transport_options不是一个选择。

但是它确实提到了request_timeout选项，该选项应该起作用。因此，将您的config/elasticsearch.yml文件更改为以下内容：

development: &default
    host: 'http://localhost:9200'
    request_timeout: !!integer 300
test:
    <<: *default
production:
    host: 'http://localhost:9200'
    request_timeout: !!integer 300

Elasticsearch：未定义的方法“ params_encoder”，用于{“ timeout” => 300，：proxy => nil}：哈希
