sequelize interprets date with hour = 2 - javascript

I'm trying to use sequelize to search for a record in my database based in a date field:
date_from2 is this value:
2017-01-09
and sequelize interprets its as a date with hour = 2:
SELECT `id`, `user_id`, `date`, `total_visits`, `created_at`, `updated_at` FROM `table1` AS `table1` WHERE `table1`.`user_id` = 123 AND `table1`.`date` = '2017-01-09 02:00:00' LIMIT 1;
And it creates a new record everytime, instead of updating it.
When it inserts, the date is inserted with this value:
2017-01-09 00:00:00
This is my code:
where = { user_id: user_id,
date: date_from2
};
values = {
user_id: user_id,
date: date_from2,
total_visits: total_visits
};
Model.findOne({where: where}).then(function (record) {
if (!record) {
// Item not found, create a new one
Model.create(values)
.then(function () {
console.log('created!');
}).error(function (err) {
console.log('error on create');
});
} else {
// Found an item, update it
Model.update(values, {where: where})
.then(function () {
console.log('updated!');
})
.catch(function (err) {
console.log('error on update');
});
}
});


Query by just using the user's user_id and not the date if you are trying to get a specific user:
Model.findOne({where: {user_id: user_id}})
The issue is that it's storing the date differently then what you are passing in. Because of this you were never able to find the existing user and you kept creating new ones. There is nothing wrong with using UTC timezone and you should be able to convert this to any other time zone.

MongoDB update many using the values of the user

I've written a function to execute hourly which looks up a user and finds some values and then pushes those values into a history collection that records the hourly updated values. I've written this so far as a test just finding a user by their ID but now I need to roll this out to my entire database of 50,000+ users.
From what I've read using updateMany is a lot more performant but I'm not entirely sure how to retrieve the document detail of the record that is being updated at the time.
Here is my code so far, which you can see I'm first looking up the user and then grabbing their valuation details which I'd like to then push into a history collection.
exports.updateUserValuationHistoric = () => {
User.find({ _id: "609961fdd989613914ef7216" })
.populate('UserValuationHistory')
.exec((err, userDoc) => {
if (err){
console.log('[ERROR]: ', err)
}
const updatedValuationHistory = {
totalValuation: userDoc[0].valuation.totalValuation,
comicsValuation: userDoc[0].valuation.comicsValuation,
collectiblesValuation: userDoc[0].valuation.collectiblesValuation,
omiValuation: userDoc[0].valuation.omiValuation
}
UserValuationHistory.findOneAndUpdate(
{ user: userDoc[0]._id },
{ $push: {
'history': updatedValuationHistory
}},
{upsert: true, new: true}
)
.exec((error, updated) => {
if (error){
console.log('[ERROR]: Unable to update the user valuation history.')
} else {
console.log('[SUCCESS]: User historic valuation has been updated.')
}
})
})
}
Any help is greatly appreciated!

Querying items between a range of dates using Mongoose

I'm trying to get my query working correctly. It's supposed to return 5 items which have a utcTime that falls between two dates. I've verified that documents in my mongoDB do have correct dates and should be returned. This query works if I remove the .where line. In fact it works if I remove the gte and lt lines. The date gets parsed correctly so I'm not sure why this query is failing me.
I've also tried the alternative which is to put a filter in the find function like this
{
"utcTime": {
"$gte": new Date(req.params.startdate),
"$lt": new Date(req.params.enddate)
}
}
But that doesn't work either.
// Get the top 5 items sorted in decreasing order by karma in between
// the specified dates
listItemRoute.route('/top5/:startdate/:enddate').get((req, res) => {
console.log(req.params.startdate) //2020-05-13T07:00:00Z
console.log(req.params.enddate) //2020-05-20T07:00:00Z
ListItem
.find()
.limit(5)
.where('utcTime').gte( new Date(req.params.startdate) ).lt( new Date(req.params.enddate) )
.sort({karma: -1})
.exec((error, data) => {
if (error) {
return next(error)
} else {
res.json(data)
}
})
})
Here's my model
// Define collection and schema
let ListItemSchema = new Schema({
name: {
type: String,
required: true
},
karma: {
type: Number
},
utcTime: {
type: Date
}
})
Everything looks correct and I've tried many other stackoverflow suggestions to no avail. Any help would be awesome.
Edit: example of DB data
{
"name": "TITLE BLAH",
"karma": 11502,
"utcTime": "2020-05-17T09:50:21Z"
}

MongoDB object not updating

I am working on a database system using MongoDB. I am trying to save the current date and time, then update it if the same barcode on ID cards is scanned twice, thrice, etc... However, the $set will not update the item. I have already looked at MongoDB documentation and other Stack Overflow posts, but nothing seems to work. Other Stack Overflow posts suggested adding
{ new: true }
and
( overwrite: true }
I tried these both separately and in tandem neither worked.
My Code:
Student.findOne({StudNum: studNum}, function(err, studNumItem) {
if (err) {
res.send("MongoDB Error: " + err);
return false;
}
if (!studNumItem) {
var myData = new Student({ StudNum: studNum, Attendance : 1, LastDateTimeAttended : {
Year: year, Month: month, Day: day, Hours: hours, Min: min, Sec: sec
}});
myData.save()
.then(item => {
res.send("saved to database: " + studNum + ", with attendance " + Attendance + "");
})
.catch(err => {
res.send("unable to save to database: " + studNum + ", for attendance " + Attendance + "");
});
}
else{
var conditions = {StudNum: studNum};
var update = {$inc : { Attendance: 1 }, $set : {
"Year": year, "Month": month, "Day": day, "Hours": hours, "Min": min, "Sec": sec
}};
Student.findOneAndUpdate(conditions, update, { new: true }, function (err)
{
if (err) // If error
{
res.send(err);
}
else {
res.send("Checked in!")
}
});
}
});
And my Schema:
var studentSchema = mongoose.Schema({
StudNum: String,
Attendance: Number,
LastDateTimeAttended: {
Year: Number,
Month: Number,
Day: Number,
Hours: Number,
Min: Number,
Sec: Number
}
});
Thanks in advance!
Edit: Just to clarify, saving the item works fine, but updating the item does not, also no errors are thrown while updating.

In your case, I'm not sure it is your find one and update that is the issue. I believe since what you are trying to update is a nested object, you need to prepend it with the top level property to get mongoose to save it. Since those properties don't exist at a top level, mongoose is just throwing it away.
var update = {
$inc : {
Attendance: 1
},
$set : {
"LastDateTimeAttended.Year": year,
"LastDateTimeAttended.Month": month,
"LastDateTimeAttended.Day": day,
"LastDateTimeAttended.Hours": hours,
"LastDateTimeAttended.Min": min,
"LastDateTimeAttended.Sec": sec
}
};

For those who don`t know the cause of the issue, it also may be that the variable is not declared in the scheme causing any alteration to be halted and ignored.

I suggest you try saving you date as a string.
LastDateTimeAttended in your model should expect a string, and new Student constructor should create LastDateTimeAttended variable by calling
let date = new Date();
LastDateTimeAttended = date.toString();
your new schema should look like
var studentSchema = mongoose.Schema({
StudNum: {type: String, required: true},
Attendance: {type: Number, required: true},
LastDateTimeAttended: {type: String, required: true}
});
you should then be able to update your mongodb document
Student.findOneandUpdate(conditions, update, callback). see working with mongoose Model.findOneandUpdate

Updating doc in Pouch DB

I have a DB in PouchDB, and I need to be able to update documents. So when I click "update" in the table I get the data from the fields into a form, then I want to change data in the form and press "Save Updated" button and have the fields updated. Here's what I've tried:
function saveUpdated(){
var vaucherID = window.document.VaucherForm.vaucherID.value;
var date = window.document.VaucherForm.date.value;
var invoiceNumber = window.document.VaucherForm.invoiceNumber.value;
var vendorID = window.document.VaucherForm.vendorID.value;
var amount = window.document.VaucherForm.amount.value;
var fund = window.document.VaucherForm.fund.value;
var deptID = window.document.VaucherForm.deptID.value;
var descript = window.document.VaucherForm.descript.value;
//I get idValue from when I have all values from DB get into form
db.get('idValue').then(function(doc) {
return db.put({
_id: 'idValue',
_rev: doc._rev,
vaucherID: vaucherID,
date: date,
invoiceNumber: invoiceNumber,
vendorID: vendorID,
amount: amount,
fund: fund,
deptID: deptID,
descript: descript
});
}).then(function(response) {
// handle response
}).catch(function (err) {
console.log(err);
});
}
So as I do this I get this error
o {status: 404, name: "not_found", message: "missing", error: true, reason: "missing"}

Hm, maybe it's because the doc._rev is undefined/null, so this is treated differently than just not including the _rev field at all? Do you have a live example to reproduce?
