I am doing a university project and I've read every post regarding my problem, but I am yet to find a solution. Maybe you can help me out.
The code is the following:
viewerObj.update({_id: currentIDViewerVar} , {minutesWatched: 5},{upsert:true} , function (err,result) { if (err) throw err; console.log("Viewer " + userNameVar + " gespeichert"); console.log("minsWatched" +minsWatched); });
I get the following error. I can't see what I am doing wrong.
events.js:160 throw er; // Unhandled 'error' event ^ TypeError: callback.apply is not a function at C:\\Users\\picco\\Desktop\\TwitchWatcher_v19\\TwitchWatcher\\node_modules\\mongoose\\lib\\model.js:3388:16 at Query.callback (C:\\Users\\picco\\Desktop\\TwitchWatcher_v19\\TwitchWatcher\\node_modules\\mongoose\\lib\\query.js:2185:9) at C:\\Users\\picco\\Desktop\\TwitchWatcher_v19\\TwitchWatcher\\node_modules\\mongoose\\node_modules\\kareem\\index.js:259:21 at C:\\Users\\picco\\Desktop\\TwitchWatcher_v19\\TwitchWatcher\\node_modules\\mongoose\\node_modules\\kareem\\index.js:127:16 at _combinedTickCallback (internal/process/next_tick.js:67:7) at process._tickCallback (internal/process/next_tick.js:98:9) Process finished with exit code 1
Thank you in advance!
You're using too many arguments.
Change this:
viewerObj.update({_id: currentIDViewerVar} , {minutesWatched: 5},{upsert:true} , function (err,result) {
if (err) throw err;
console.log("Viewer " + userNameVar + " gespeichert");
console.log("minsWatched" +minsWatched);
});
to this:
viewerObj.update({_id: currentIDViewerVar, minutesWatched: 5}, {upsert:true}, function (err,result) {
if (err) throw err;
console.log("Viewer " + userNameVar + " gespeichert");
console.log("minsWatched" +minsWatched);
});
See the docs:
If you're updating a mongoose document, you don't pass in a query as the first parameter.
see the Docs for Document#update .
Thus, this update method expects 3 parameters with the third being the callback and you pass in an object ( {upsert: true}
) where the update method expects the callback. That's why you get callback.apply is not a function
. Simply because { upsert: true }
is not a function.
In my case, I was facing this issue with aggregate method of mongoose (5.1.2). The same code was working on <4.9 but got broken on upgrading to 5.
I just added capital braces in my query
User.aggregate([{
$match: {
isDeleted: 0,
isActive: 1,
_id: Mongoose.Types.ObjectId(userId)
}
}, {
$project: {
claps: 1,
showIcon: { $cond: [{ $gt: [{ $size: "$userBadges" }, 0] }, 1, 0] },
}
}])
.exec(function (err, data) {});
