Mongoose async / await find then edit and save?

Question

Is it possible to do a search and then save using an asynchronous / pending promise?

I have the following code:

try {
    var accounts = await Account.find()
    .where("username").in(["[e-mail]"])
    .exec();
    accounts.password = 'asdf';
    accounts.save();
} catch (error) {
    handleError(res, error.message);
}

and I get the following error:

ERROR: accounts.save is not a function

Answer 1

This is what I was looking for:

try {
    var accounts = await Account.findOneAndUpdate(
        {"username" : "[e-mail]"},
        {$set: {"password" : "aaaa"}},
        {new : true}
    );
    res.status(200).json(accounts);
} catch (error) {
    handleError(res, error.message);
}

or (thanks @JohnnyHK for the find help and tipOne!):

try {
    var accounts = await Account.findOne()
    .where("username").in(["[e-mail]"])
    .exec();
    accounts.password = 'asdf';
    accounts.save();
    res.status(200).json(accounts);
} catch (error) {
    handleError(res, error.message);
}
