我想检索最后插入的 _id

推荐答案
我正在使用mongoose版本1.2 .0,一旦我创建了一个新的mongoose模型实例,就已经设置了 _id
。
I'm using mongoose version 1.2.0 and as soon as I created a new instance of a mongoose model, the _id
is already set.
coffee> u = new User()
[object Object]
coffee> u._id
4dd68fc449aaedd177000001
我也验证了在我打电话 u.save()
_id
保持不变。我通过MongoHub验证,这确实是保存到MongoDB中的真实ID。
I also verified that after I call u.save()
the _id
remains the same. I verified via MongoHub that this is indeed the real ID saved into MongoDB.
