Ruby on rails 无法在Nitrous.io上创建数据库

我已经在nitrous.io上成功创建了on应用程序，并为该应用程序初始化了postgres数据库。我现在正试图在同一个框中为第二个应用程序配置数据库

当我为新应用程序运行bundle exec rake db:create时，我收到以下错误消息

雷克流产了

未配置开发数据库
/home/action/.rvm/gems/ruby-2.0.0-p247/gems/activerecord-3.2.13/lib/active\u record/connection\u adapters/abstract/connection\u specification.rb:39:在“解析字符串\u连接”中

（通过使用--trace运行任务查看完整跟踪）

如果运行bundle exec rake db:create:all，则会收到以下错误消息：

（通过使用--trace运行任务，请参阅完整跟踪。）

那么，创建数据库的正确方法是什么

我的db/database.yml文件如下：

# database configuration for Nitrous.io
development:
adapter: postgresql
encoding: unicode
database: better_life-dev
pool: 5
host: localhost
username: action
password:
  # Connect on a TCP socket. Omitted by default since the client uses a
  # domain socket that doesn't need configuration. Windows does not have
  # domain sockets, so uncomment these lines.
  #host: localhost

  # The TCP port the server listens on. Defaults to 5432.
  # If your server runs on a different port number, change accordingly.
  #port: 5432

  # Schema search path. The server defaults to $user,public
  #schema_search_path: myapp,sharedapp,public

  # Minimum log levels, in increasing order:
  #   debug5, debug4, debug3, debug2, debug1,
  #   log, notice, warning, error, fatal, and panic
  # Defaults to warning.
  #min_messages: notice
# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
adapter: postgresql
database: better_life-test
pool: 5
host: localhost
username: action
password:

production:
  adapter: postgresql
  encoding: unicode
  database: better_life-prod
  pool: 5
  host: localhost
  username: action
  password:

您是否尝试将同一数据库用于两个不同的应用程序？

其他应用程序的

database.yml

的内容应与此应用程序不同。

您需要确保为

config/database.yml

文件将每个设置缩进两个空格。请尝试使用这些设置和精确的格式：

development:
  adapter: postgresql
  encoding: unicode
  database: better_life-dev
  pool: 5
  host: localhost
  username: action
  password:

test:
  adapter: postgresql
  database: better_life-test
  pool: 5
  host: localhost
  username: action
  password:

production:
  adapter: postgresql
  encoding: unicode
  database: better_life-prod
  pool: 5
  host: localhost
  username: action
  password:

我对此投了更高的票，因为它值得在两个应用程序中检查相同的数据库。在我的情况下，gman给出了答案。谢谢你的礼貌。
