Rubymine PostgreSQL 数据库

Question

我正在尝试使用 Rubymine 在 vagrant 设置中连接到我的 postgres 数据库，但我遇到了问题。任何帮助将不胜感激。 JDBC 对我来说是一个新战线。

192.168.50.50 是我在 vagrant 文件中使用的

 config.vm.network :private_network, ip: '192.168.50.50'

这就是我在 Rubymine 中的数据库设置的样子。

我不断收到以下错误

java.sql.SQLException: The connection attempt failed.

3000端口是转发端口，我也在用SSH隧道

如果我尝试在没有主机和端口值的情况下进行连接（即只留下 SSH 信息），我最终会得到这个

如果有人能提供帮助，那将意义重大

对于那些可能处于相同位置的人，请检查您在 postgres 中的端口。打开 5432 并在我的ruby中配置它，你应该准备好了。
