我在cucumber和数据库事务方面遇到了一些问题——特别是，当我运行测试套件时，数据库事务在之后不会被清理

我正在用spork和postgres运行rails 3.1

最初，features/support/env.rb设置为使用database_cleaner，但每次调用db时都会出现以下错误：

我试着恢复正常交易，但没有任何乐趣。我可以通过控制台（cucumber环境）访问数据库，并可以毫无问题地创建/删除/检索记录。下面添加了config/database.yml、features/support/env.rb、config/environments/cucumber.rb和rspec/spec_helper.rb文件。非常感谢您的任何建议-这一建议让我困惑了一段时间：

production:
  <<: *defaults
