当我尝试保存一些对象时，我得到了以上响应。以下是我的Mongoid和mongo的 gem 版本，我认为这是mongoid.yml的问题，但不确定，因为我的yml非常好

使用bson(1.3.1)
使用bson_ext(1.3.1)
使用mongo(1.3.1)
安装Mongoid(2.1.9)

蒙古扁 bean

defaults: &defaults
  host: localhost

development:
  <<: *defaults
  database: gm_development

test:
  <<: *defaults
  database: gm_test
production:
  host: <%= ENV['MONGOID_HOST'] %>
  port: <%= ENV['MONGOID_PORT'] %>
  username: <%= ENV['MONGOID_USERNAME'] %>
  password: <%= ENV['MONGOID_PASSWORD'] %>
  database: <%= ENV['MONGOID_DATABASE'] %>
  uri: mongodb://username:[email protected]:10029/appid

如果您发现任何错误，请告诉我

最佳答案

尝试:

u.save(:validate=> false)
