试图在Heroku上通过Rake导入ElasticSearch模型的连接拒绝错误

Question

出于某种原因，在heroku上，它将不允许我导入模型(这是为盆景ElasticSearch插件)。只是显示连接被拒绝了。我不知道怎么解决这个问题。我在互联网上搜索过，我找不到任何能提示我解决这个问题的正确方向的东西。我检查以确保服务器已启动，并使用curl手动创建索引。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 url：

配置/初始化器/bonsai.rb

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

Gemfile片段

# 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，可以创建一个'elasticsearch-rails‘标签，因为它即将取代轮胎

Elasticsearch不使用与Tire相同的机制在Heroku上设置其在生产中的URL。要正确使用盆景搜索，您必须有一个不同的url规范。幸运的是，一个家伙已经做了一个创业板(https://rubygems.org/gems/bonsai-elasticsearch-rails)，以消除不必要的，强制性的创建一个初始化程序由每个人。

只需将此创业板添加到生产组下的创业板文件中即可。这个版本可能会被修改，因为它太新了：

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

如果您对这个宝石的实际功能更感兴趣，那么整个源代码如下：

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']

我知道简单的权利..。
