ruby-on-rails - rails : Cucumber not cleaning DB

Question

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，之后不会清理数据库事务。

我正在使用 spork、postgres 运行 Rails 3.1。

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

No database specified. Missing argument: database. (ArgumentError) /Users/john/.rvm/gems/ruby-1.9.2-p290/gems/activerecord-3.1.0.rc4/lib/active_record/connection_adapters/postgresql_adapter.rb:22:in postgresql_connection'

我尝试恢复到常规交易，但没有任何乐趣。我可以通过控制台(cucumber 环境)访问数据库并创建/删除/检索记录，没有任何问题。下面添加了 config/database.yml、features/support/env.rb、config/environments/cucumber.rb 和 rspec/spec_helper.rb 文件。任何建议都非常感谢 - 这个让我难倒了一段时间:

配置/数据库.yml

default: &defaults
  adapter: postgresql
  username: rails_dev
  password: foobar

development:
  <<: *defaults
  database: fcct_d

test: &test
  <<: *defaults
  database: fcct_t

production:
  <<: *defaults
  database: fcct_p
  username: fcct
  password: k#1*5Avb3dTa

cucumber:
  adapter: postgresql
  username: rails_dev
  password: foobar
  database: fcct_t

对于那些想知道的人 - 这是我的 config/database.yml 文件中有 &defaults 的事实。数据库清理器有一个自己的“默认”调用，它拦截配置信息。
