Update many in mongoose

manpreet Best Answer 3 years ago

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?

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

Simple query is like this

db.collection.updateMany(filter, update, options)

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

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

here you need to use $set 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
