Update many in mongoose

I have a very simple case. I want to update my collection every midnight.
Im using `node-schedule`:

schedule.scheduleJob('0 0 * * *', () => {
Users.updateMany();
});

All I want to do, is to loop over every document in my collection (`Users`) and then if `User.created` is `false`, I want to turn it into `true`.

In javascript it would be:

for (let user in Users) {
if (user.created === false) {
user.created = true;
}
}

How to do it in mongoose? Thanks!


### **Edit**: The story is very simple, I just want to iterate over every element in my db using mongoose and if iterated element has field "created" === false, change it to true.

You first need a query to find the documents you want to update. This is simply:

{"created": false}

Then you need an update query to tell mongo how to update those documents:

{"$set":{"created": true}}

You need to use the `$set` operator to specify which fields to change, otherwise it will overwrite the entire document. Finally you can combine these components into a single mongo call with an additional parameter to tell mongo we want to modify multiple documents:

User.update({"created": false}, {"$set":{"created": true}}, {"multi": true}, (err, writeResult) => {});

Mongoose tries to closely replicate the mongo API so all this information can be found solely within MongoDB's documentation:

You can use **`updateMany()`** methods of mongodb to update multiple document

Simple query is like this

db.collection.updateMany(filter, update, options)
For more doc of uppdateMany read [here][1]

As per your **requirement** the update **code** will be like this:

User.updateMany({"created": false}, {"$set":{"created": true}});

here you need to use [$set][2] because you just want to change created from true to false. For ref. If you want to change entire doc then you don't need to use **$set**
