Prettier way to write this query?

Question

hi is there a nicer / prettier way to write this query?

exports.list = function(req, res) {
if (req.user.roles.indexOf('admin') == 1) {
    Timesheet.find()
        .sort('-created').populate('user', 'displayName').exec(function (err, timesheets) {
            if (err) {
                return res.status(400).send({
                    message: errorHandler.getErrorMessage(err)
                });
            } else {
                res.jsonp(timesheets);
            }
        });
}
else {


Timesheet.find()
    .where('user').equals(req.user.id)
    .sort('-created').populate('user', 'displayName').exec(function (err, timesheets) {
        if (err) {
            return res.status(400).send({
                message: errorHandler.getErrorMessage(err)
            });
        } else {
            res.jsonp(timesheets);
        }
        });
}
};

only different is, if admin then add .where('user').equals(req.user.id)

To eliminate the duplicate code you can refactor the code to just alter the way the query is built based on whether the user is in the admin role:

exports.list = function(req, res) {
    var query = Timesheet.find();
    if (req.user.roles.indexOf('admin') !== 1) {
        query = query.where('user').equals(req.user.id);
    }
    query.sort('-created').populate('user', 'displayName').exec(function(err, timesheets) {
        if (err) {
            return res.status(400).send({
                message: errorHandler.getErrorMessage(err)
            });
        } else {
            res.jsonp(timesheets);
        }
    });
}
