Mongoid在轨道控制台上保存记录时抛出错误

Question

我使用轨道4.2.0.beta2沿着mongoid 4.0.0它在浏览器中正常工作，但是当我在轨道控制台中尝试它时，我可以实例化对象，但它不保存记录，而是引发以下错误

Mongoid::Errors::NoSessionConfig: 
Problem: 
No configuration could be found for a session named 'default'. 
Summary: 
When attempting to create the new session, Mongoid could not find a session configuration for the name: 'default'. This is necessary in order to know the host, port, and options needed to connect. 
Resolution: 
Double check your mongoid.yml to make sure under the sessions key that a configuration exists for 'default'. If you have set the configuration programatically, ensure that 'default' exists in the configuration hash.

mongoid.yml

development: 
    sessions: 
    default: 
     database: okaab_development 
     hosts:
