ruby-on-rails - 尝试通过Heroku上的Rake导入ElasticSearch模型时出现连接被拒绝的错误

Question

由于某些原因，在heroku上它不允许我导入模型(这是Bonsai ElasticSearch附加组件的模型)。它只是显示连接被拒绝。我不确定如何解决此问题。我已经搜索了互联网，却找不到任何能提示我正确方向来解决此问题的信息。我检查以确保服务器已启动，并使用curl手动创建了索引。运行rake任务时是否启动初始化程序？

我在config / initializers / bonsai.rb文件中设置了elasticsearch网址:

config / initializers / bonsai.rb

if Rails.env == 'production'
  ENV['ELASTICSEARCH_URL'] = ENV['BONSAI_URL']
end

Gemfile代码段

# Used for elastic search
gem 'elasticsearch-model', github: 'elasticsearch/elasticsearch-rails'
gem 'elasticsearch-rails', github: 'elasticsearch/elasticsearch-rails'
gem 'multi_json'
gem 'json'

错误

顺便说一句，因为它即将取代Tire ，因此有人可以创建“elasticsearch-rails”标签

Answer 1

Elasticsearch Rails使用与Tyre不同的机制在Heroku上的生产环境中设置其URL。为了使此功能在Bonsai搜索中正常工作，您必须具有其他的URL规范。幸运的是，一个人做了一个gem(https://rubygems.org/gems/bonsai-elasticsearch-rails)，以消除每个人不必要的，强制性的初始化程序创建过程。

只需将此 gem 添加到生产组下的 gem 文件中即可。由于版本太新，因此可能会更改:

gem 'bonsai-elasticsearch-rails', '~> 0.0.4'

如果您对这个gem的实际用途更加好奇，请参见以下完整资源:

require "bonsai/elasticsearch/rails/version"

puts "Starting up a new ElasticSearch client with #{ENV['BONSAI_URL']}"
Elasticsearch::Model.client = Elasticsearch::Client.new url: ENV['BONSAI_URL']

我知道，简单吧...
