Question

我试图使用rake＆＃39; rake db:structure:dump转储我的远程数据库的结构，但每当我运行该命令时，它会忽略我database.yml文件中的用户并使用我本地计算机上的用户，我已登录为。

database.yml中：

 development: &DEFAULT
  adapter: postgresql
  host: remoteaddress.com
  port: 5432
  user: myusername
  password: mypassword
  database: mydatabase

当我运行命令时会发生这种情况：

[~/src/myapp]$ RAILS_ENV=development rbbe rake db:structure:dump --trace                                                                                                                                                                          ✭ git:em-redshift ruby:2.2.0

Tasks: TOP => db:structure:dump

如您所见，它不会将myusername用作用户。而是将其作为我的本地用户（emai）运行。发生了什么事？

P.S。我知道db配置也有效，因为我进入了rails控制台并查询了记录并得到了结果。此外，rake db:schema:dump不会出现身份验证错误。

在查看文档（https://github.com/rails/rails/blob/master/activerecord/lib/active_record/tasks/postgresql_database_tasks.rb）后，您需要添加username密钥才能使其正常运行......认真......

 development: &DEFAULT
  adapter: postgresql
  host: remoteaddress.com
  port: 5432
  user: myusername
  username: myusername <-------
  password: mypassword
  database: mydatabase

Rails：Postgres + rake db：structure：使用错误的用户转储
