我正在开发一个Rails应用程序。使用的数据库是OrientDB。我正在使用active-orient gem。一切都运行良好，直到我更新我的Bundler版本。之后，我无法使用rails c打开Rails控制台。以下是错误堆栈
$ rails c
Railtie included!!

我的config/application.yml文件：
development:
orientdb_port: 2480
orientdb_server: <some-ip>
orientdb_root_username: <some-username>
orientdb_root_password: <some-password>
orientdb_database: <some-db-name>
我用来提供OrientDB gem详细信息的config/connect.yml文件：
:orientdb:
:server: ENV["orientdb_server"]
:port: ENV["orientdb_port"]
:logger: stdout
:database:
:development: ENV["orientdb_database"]
:production: ENV["orientdb_database"]
:test: ENV['orientdb_database']
:staging: ENV['orientdb_database']
:admin:
:user: ENV['orientdb_root_username']
:pass: ENV['orientdb_root_password']
我认为此文件未正确加载。这可能是什么问题？ 我甚至降级了捆绑版本，但仍然无效。

development:
orientdb_port: '2480'
orientdb_server: 'some-ip'
orientdb_root_username: 'some-username'
orientdb_root_password: 'some-password'
orientdb_database: 'some-db-name'
在终端运行中：figaro install
这将包括（.gitignore）

您的config/connect.yml文件应如下所示：
orientdb:
server: <%= ENV['orientdb_server'] %>
port: <%= ENV['orientdb_port'] %>
logger: stdout
database:
development: <%= ENV['orientdb_database'] %>
production: <%= ENV['orientdb_database'] %>
test: <%= ENV['orientdb_database'] %>
staging: <%= ENV['orientdb_database'] %>
admin:
user: <%= ENV['orientdb_root_username'] %>
pass: <%= ENV['orientdb_root_password'] %>
YML 不是 Ruby，因此您必须使用Ruby语句的erb标记来访问环境变量。这同样适用于config/application.yml。
如果仔细查看错误消息，您会看到以下行几乎说明了失败的原因：
/home/ubuntu/.rvm/rubies/ruby-2.4.0/lib/ruby/2.4.0/uri/rfc3986_parser.rb:67:in `split': bad URI(is not URI?): http://localhost:2480/connect/ENV['orientdb_database'] (URI::InvalidURIError)
具体来说，http://localhost:2480/connect/ENV['orientdb_database'] (URI::InvalidURIError)表示您将字符串ENV['orientdb_database']传递给连接而不是实际的环境变量。
答案 2 :(得分：0)
假设您使用的是最新版本的active-orient（来自github），请查看lib目录中的railties.rb文件。
connect_file = Rails.root.join('config', 'connect.yml')
databaseyml = YAML.load_file( connect_file )[:orientdb][:database]
因此：yaml标记必须是：orientdb：和：database：
您可以轻松调试输入，将控制输出添加到railtie文件中 例如
puts "DATABASEYML :#{databaseyml.inspect}"
如果使用Environment-variable设置数据库，只需将其分配给ActiveOrient.database
ActiveOrient.database = ENV['orientdb_database']
任何事都应该有用。
