Question

我刚开始学习Ruby on Rails，遵循示例书。我不确定Rspec是否适合我。

Git：https://github.com/ivawzh/sample_app

Heroku：http://sampleappofivawzh.herokuapp.com/pages/contact

因为我能够从rails服务器向数据库添加数据。我猜Postgresql工作正常。但每次我启动rspec时，它都会给出下面的错误。（我不确定rspec是否有效，因为我之前从未使用过它）

Answer 1

Rspec将使用您的test环境，因此您需要确保test:的{{1}}部分包含您的用户名，密码等的正确设置。

（看看你的github回购，看起来你只为config/database.yml模式填写了这个。）

连接到db，但是rspec在`initialize＆＃39;中表示：致命：用户密码验证失败＆＃34; sample_app＆＃34; （PG ::错误）
