单行命令来迭代和查找多个项目并更新猫鼬？

Question

I am wondering if there is specific query line to iterate over mongodb and update? For example, i have data with '{"name": "A", "age": 23} .... {"name":"Z", "age":25}' as such,

I want to iterate over with a list of names = [A,B,C,D] and a list of ages = [30,40,25,23] .

I was thinking about for

for(var i in names){ people.findoneandupdate("name": names[i], {$set:{"age":ages[i]}})

is there single line query to solve this?

If you want to update multiple docs in one query you can go with this:

Model.update(conditions, update, options, callback);

Here if you put options = { multi: true } then it will update multiple doc according to given condition
