我制作了一个简单的编码 ruby 程序,用于从远程服务器获取备份,并在 postgresql 中制作了一个数据库,用于保存信息和安排备份。
与数据库的连接是使用 ActiveRecord 完成的,我配置为访问内部数据库(在其他服务器中),但是当我尝试连接到远程数据库时,我收到以下消息:

PG 尝试使用我的本地用户连接到远程数据库,在 ActiveRecord 的声明中我设置了参数:
require 'active_record'
ActiveRecord::Base.establish_connection(
:adapter => "postgresql",
:host => "xxx.xxx.x.101",
:port => 5432,
:database => "VB_DB",
:user => "pg_user",
:password => "blahblah"
)
我使用 Ruby 1.8.7。
对此有任何想法吗?
感谢阅读,帮助我。
问候。

我找到了解决方案:
ActiveRecord::Base.establish_connection( :adapter => "postgresql", :host => "xxx.xxx.x.101", :port => 5432, :database => "VB_DB", :username => "pg_user", :password => "blahblah" )
我使用了:user,并且必须是:username。真丢人。
