ruby on rails-连接被拒绝错误尝试通过Rake on Heroku导入ElasticSearch模型

Question

由于某些原因，在heroku上它不允许我导入模型（这是用于Bonsai ElasticSearch插件）。只是显示连接被拒绝。我不知道如何解决这个问题。我在互联网上搜索过，找不到任何能提示我解决这个问题的正确方向的东西。我检查了一下以确保服务器已启动，并使用curl手动创建了索引。初始化程序是否在运行rake任务时启动？

我在config/initializers/bonsai.rb文件中设置了弹性搜索url：

config/initializers/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，有人能创建一个"弹性搜索轨道"标签吗？因为它即将取代轮胎

Elasticsearch Rails在Heroku上的生产中没有使用与Tire相同的机制来设置其URL。为了让这项工作与盆景搜索正确，你必须有一个不同的url规范。幸运的是，有个人做了一颗宝石(https://rubygems.org/gems/bonsai-elasticsearch-rails)以消除每个人不必要的、强制性的初始化器创建。

只需将此宝石添加到您的生产组下的宝石文件中即可。版本可能会发生变化，因为它是如此的新：

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

如果你更好奇这块宝石的实际作用，整个来源如下：

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。。。
