Comes from the line "menu.update({name:request.body.name}, menuObject,
{upsert: true}, onUpdate)"
It's because mongoose update takes three arguments: document, options,
callback. You have object, object, options, callback; thus mongoose thinks
your options object is the callback.
rewrite as:
var onUpdate = function (err, num, raw) {
if (!err) {
logger.info('information stored');
return myResponse.send ({status: 'ok' });
} else {
logger.info (err);
if(err.name == 'ValidationError') {
myResponse.statusCode = 400;
myResponse.send({ error: 'Validation error'});
logger.info(req.body);
} else {
myResponse.statusCode = 500;
myResponse.send({ error: 'Server error' });
}
logger.error('internal error(%d):%s');
}
}
function onPostMenuUpdate (request,response) {
logger.info("In onPostMenuUpdate");
myResponse=response;
var menu = new model.MainMenuModel ({
'name': request.body.name,
'link': request.body.link,
'drop': request.body.drop
});
var menuObject=menu.toObject();
menuObject.name = request.body.name
menu.update(menuObject, {upsert: true}, onUpdate);
}
& that should work
