rake在推送到heroku時中止不接受TCP/IP連接

我只是坐在這裏試圖將我的應用部署到最近4小時的heroku。rake在推送到heroku時中止不接受TCP/IP連接

我只是想推進我的更改，但每次推送我的更改時都會顯示以下內容。

rake aborted! The driver encountered an unknown error: org.postgresql.util.PSQLException: Connection refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.

我運行一個應用程序rails 4.0.2與jruby 1.7.4和ruby 1.9.3。

我已經使用過這個擴展。 https://devcenter.heroku.com/articles/labs-user-env-compile 但它也無濟於事。

這裏有一個更詳細的堆棧跟蹤

好吧，請按照錯誤消息的建議。「檢查主機名和端口是否正確，並且postmaster正在接受TCP/IP連接。」從'psql -h the_hostname -p the_port -U myusername the_databasename'開始。 –

謝謝您的評論！我可以設置這些設置嗎？我以爲我只是需要一個git push來開始部署，而heroku會處理背景中的所有內容...... – pmuens

哦，當在Heroku上推送並運行時，錯誤發生在本地。在那種情況下，沒關係。 –

所以這一個真的很奇怪。

經過近一整天的調試，我才解決了這個問題。

它與jRuby沒有任何關係，也沒有與主動記錄適配器（如果使用ruby-Runtime而不是jruby-Runtime將其推送到heroku，會得到非常類似的錯誤）。

的問題，是由這條線在我的模型

validates_presence_of :terms_of_service

之一引起的註釋出來，按向Heroku的後再次一切都很好。

奇數...

你可以試試這個？

集username: systemuser, host: localhost在YAML文件

如果上述解決方案不起作用，請參考以下鏈接：

希望這能解決您的問題！

謝謝你的回答。不幸的是，這並沒有解決問題。我以爲Heroku會用自己的配置覆蓋database.yml-File ...... – pmuens
