mongodb javascript update

Question

How do I update a mongodb collection from JS?

db.collection('fruits', function (err, collection) {
    collection.update({ "_id": content.fruitID}, content, function () {
    });
});

Am I doing this right? DO I need to use $set?

Basically content is a json object that should replace the document that's found.

Thanks.

I'm using the mongodb node native driver.

If you want to replace the document you're doing the right thing. If you want to update a field of the existing document you should use $set.
