我正在尝试通过rails console
连接到现有的mLab数据库。每次我查询(例如GameScore.all.count
,User.all.count
)时,我都会收到以下错误消息:
Mongo::Error::NoServerAvailable: No server is available matching preference: #<Mongo::ServerSelector::Primary:0x70240308536180 tag_sets=[] max_staleness=nil> using server_selection_timeout=30 and local_threshold=0.015 from /Users/-/.rbenv/versions/2.2.3/lib/ruby/gems/2.2.0/gems/mongo-2.4.1/lib/mongo/server_selector/selectable.rb:115:in `select_server'
以下是我的mongoid.yml
文件的设置方式:
development:
clients:
default:
uri: 'mongodb://username:password@host:port/db_name'
options:
consistency: :strong
max_retries: 30
retry_interval: 1
timeout: 15
非常感谢任何帮助。现在真的很难过。
答案 0 :(得分:0)
解决。不得不降级到Rails 4.2.7和mongoid 4.工作就像一个魅力。
