当我试图保存某个对象时，我得到了上述响应。下面是我的mongoid和mongo的gem版本，我认为这是mongoid.yml的问题，但不确定我的yml是否完美

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）

我在发布我的对象时，在Rails 3.0中遇到了错误：

false的未定义方法“[]”：FalseClass

但在我将代码从以下位置更改为

save(false)

致：

用户类的定义是什么？请尝试
save（：validate=>false）
@apreading谢谢它对我有用：）@umair:那就作为答案发布吧。请接受这一点这并不能真正解决根本问题，是吗？把头埋在沙子里只会让这个问题突然出现elsewhere@BillLeeper:OP以前尝试跳过验证，但使用了旧语法
u.save（false）
。出现错误消息是因为语法错误。此答案如何在已接受的答案之外添加新信息？
save(false)

save(:validate=> false)
