示例代碼如下：
var UserSchema = new Schema({
interactions: [{
interactor: {
type: Schema.Types.ObjectId,
ref: 'User'
}
}]
});
我現(xiàn)在想根據(jù)userId匹配所有interactor的值為userId的interaction，用mongoose如何能做到呢？

I found a solution to the matching problem, which is very intuitive:
User.find({
'interactions.interactor': mongoose.Types.ObjectId(user._id)
}, function (err, users) {
}
But in the callback function, I will update multiple matching users. How should I save it after the update? If there is no users.save() method, do I have to write loop save myself?
