Faraday :: ConnectionFailed：保存到mongo數據庫時拒絕連接

Question

您好RoR + Mongo（Mongoid）應用程式在這里

什么是即時錯誤消息？

Faraday::ConnectionFailed: connection refused: localhost:9200

什么時候發生？ 當我嘗試在控制台中保存用戶實例時

User.create!(email:"kevin@gmail.com",password:"helloWorld123",password_confirmation:"helloWorld123")

我將不勝感激任何幫助或投入。 祝您有美好的一天並感謝您的閱讀。 以下是相關代碼的詳細信息

Answer 1

請確保您的Elasticsearch正在運行

Answer 2

每當創建用戶時，都會在elasticsearch中更新索引，這是Elasticsearch錯誤並且未正確配置端口
