当我尝试保存一些对象时，我得到了上述响应。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 完全没问题

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)

mongoid.yml

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:password@staff.mongohq.com:10029/appid

如果您发现这里有任何问题，请告诉我

Answer 1

尝试：

u.save(:validate=> false)

Answer 2

我在发布我的对象并在 Rails 3.0 中收到错误：

未定义的方法 `[]' for false:FalseClass

但是在我更改代码后现在可以找到：

save(false)

到：

save(:validate=> false)
