导轨:黄瓜不清洁DB

Question

我在黄瓜和数据库事务方面遇到了一些问题 - 具体来说,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feature/support/env.rb设置为使用database_cleaner,但在每次调用db时始终出现以下错误:

没有指定数据库.缺少参数:数据库.(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' /Users/john/.rvm/gems/ruby-1.9.2-p290/gems/activerecord-3.1.0.rc4/lib/active_record/connection_adapters/abstract/connection_pool.rb:292:innew_connection'/ Users/john /.rvm/gems/ruby-1.9.2-p290/gems/activerecord-3.1.0.rc4/lib/active_record/connection_adapters/abstract/connection_pool.rb:302:in checkout_new_connection' /Users/john/.rvm/gems/ruby-1.9.2-p290/gems/activerecord-3.1.0.rc4/lib/active_record/connection_adapters/abstract/connection_pool.rb:254:inblock(2级)结账时'/ Users/john/.rvm/gems/ruby​​-1.9.2-p290/gems/activerecord-3.1.0.rc4/lib/active_record/connection_adapters/abstract/connection_pool.rb:250:loop' /Users/john/.rvm/gems/ruby-1.9.2-p290/gems/activerecord-3.1.0.rc4/lib/active_record/connection_adapters/abstract/connection_pool.rb:250:inin checkout'/ Users/john /. rvm/rubies/ruby​​-1.9.2-p290/lib/ruby​​/1.9.1/monitor.rb:201:in mon_synchronize' /Users/john/.rvm/gems/ruby-1.9.2-p290/gems/activerecord-3.1.0.rc4/lib/active_record/connection_adapters/abstract/connection_pool.rb:249:incheckout' /Users/john/.rvm/gems/ruby-1.9.2-p290/gems/ activerecord -3.1.0.rc4/lib/active_record/connection_adapters/abstract/connection_pool.rb:151:in connection' /Users/john/.rvm/gems/ruby-1.9.2-p290/gems/activerecord-3.1.0.rc4/lib/active_record/connection_adapters/abstract/connection_pool.rb:388:inretrieve_connection' /Users/john/.rvm/gems/ruby-1.9.2-p290/gems/activerecord- 3.1.0. rc4/lib/active_record/connection_adapters/abstract/connection_specification.rb:107:in retrieve_connection' /Users/john/.rvm/gems/ruby-1.9.2-p290/gems/cucumber-rails-1.0.2/lib/cucumber/rails/hooks/active_record.rb:7:inconnection' /Users/john/.rvm/gems/ruby-1.9.2-p290/gems/database_cleaner-0.6.7/lib/database_cleaner/ active_record /反 action.rb:17:in clean' /Users/john/.rvm/gems/ruby-1.9.2-p290/gems/database_cleaner-0.6.7/lib/database_cleaner/base.rb:77:inclean block in clean' /Users/john/.rvm/gems/ruby-1.9.2-p290/gems/database_cleaner-0.6.7/lib/database_cleaner/configuration.rb:56:in'/Users/ john/.rvm/gems/ruby-1.9.2-p290/gems/database_cleaner-0.6.7/lib/database_cleaner/configuration.rb:56:in each'/ Users /john/.rvm/gems/ruby-1.9.2-p290/gems/database_cleaner-0.6.7/lib/database_cleaner/configuration.rb:56:in clean' /Users/john/.rvm/gems/ruby-1.9.2-p290/gems/cucumber-rails-1.0.2/lib/cucumber/rails/hooks/database_cleaner.rb:9:in'之后'

我试过恢复常规交易,但没有快乐.我可以通过控制台(黄瓜环境)访问数据库并创建/删除/检索记录没有问题.下面添加了config/database.yml,features/support/env.rb,config/environments/cucumber.rb和rspec/spec_helper.rb文件.任何建议都非常感激 - 这个让我难过了一段时间:

CONFIG/database.yml的

  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

cucumber:
  adapter: postgresql

对于那些想知道的人 - 事实上我的 config/database.yml 文件中有 &defaults 。数据库清理器有自己的“默认”调用，它会拦截配置信息。
