Saving a mongo document with mongoose returns the updated document, but didn't save in the database

My issue today is with MongoDB and mongoose in javascript. So first off I have this schema:
var playerModel = new Schema({
user: {
type: mongoose.Schema.Types.ObjectId,
ref: "Users",
},
class: {
type: String,
required: true,
},
level: {
type: Number,
default: 1,
},
spells: {
type: [String],
default: ["", "", "", "", ""],
},
inventory: [], <- IMPORTANT
toolbelt: {
axe: [{}],
pickaxe: [{}],
fishingrod: [{}],
hammer: [{}],
saw: [{}],
sewingkit: [{}],
knife: [{}],
gemkit: [{}],
food: [{}],
potion: [{}],
},
gear: {
weapon: [{}],
head: [{}],
chest: [{}],
gloves: [{}],
legs: [{}],
shoes: [{}],
earrings: [{}],
ring: [{}],
necklace: [{}],
},
gold: {
type: Number,
default: 0,
},
bagSize: {
type: Number,
default: 20,
},
skills: {
type: [userSkills],
default: defaultSkills,
},
});
and my problem is with inventory: [].
In my code I manually push items in my array which save properly in the database, but whenever I wanna modify a field of one of my array object, it won't update it like a qty for example:
player.inventory[i].qty += 1; //Where player is my model containing my inventory
...
player.save()
.then((doc) => console.log("DOC", doc))
.catch((err) => console.log("ERR", err));
and the doc returned look something like this:
...
inventory: [
{
_id: 626a1468cdbeced19102942d,
slug: 'crude_campfire',
qty: 1,
charges: 19,
efficiency: -0.2
},
{ _id: 626a14e7530afad2c5c1894c, slug: 'wheat', qty: 1 },
{ _id: 626a14f1530afad2c5c1894d, slug: 'carrot', qty: 1 },
{ _id: 626a150f530afad2c5c1894e, slug: 'potato', qty: 1 },
{ _id: 626a155b530afad2c5c1894f, slug: 'red_bream', qty: 1 },
{ _id: 626a15b5530afad2c5c18950, slug: 'bone', qty: 1 },
{ _id: 626a15c9530afad2c5c18951, slug: 'clam_shell', qty: 1 },
{ _id: 626a15d5530afad2c5c18952, slug: 'stone', qty: 8 },
{ _id: 626a15df530afad2c5c18953, slug: 'taeroot', qty: 1 },
{ _id: 626a15e9530afad2c5c18954, slug: 'shiny_pendant', qty: 1 },
{ _id: 626a15fd530afad2c5c18955, slug: 'sickleweed', qty: 1 },
{ _id: 626a1625530afad2c5c18956, slug: 'ceruleaf', qty: 1 },
{ _id: 626a1dba272403ea21fb71ef, slug: 'stone', qty: 1 },
{ _id: 626a1e4030a144f8179789e0, slug: 'birch_log', qty: 22 }, <- IMPORTANT
{ _id: 626a1e72372733f90cfdc003, slug: 'tree_twig', qty: 2 },
{ _id: 626a1e9a372733f90cfdc004, slug: 'honey', qty: 2 }
],
...
where you can see that my birch_log qty is now at 22. But whenever I go check in the database,
I don't know what's going on, and I'm kind of tired right, so I'll go to bed hoping someone can save me tomorrow :)
Thanks and have a good night ! :)

To update the object having {slug: birch_log}, you can use the following query:
player.update( {user : 123456 , inventory.slug : "birch_log" } ,
{$inc : {"inventory.$.qty" : 1} });
instead of using save() with promise, you can use update() query with async await. It will be short and clean code.

This answer fixed my problem
Since i'm using an "anonymous" array or whatever, mongoose doesn't know what changes to track in it so I need to tell it that it's been modified !

GTM - Creating a list of products in GTM - Wordpress

Ahoy,
i am using built in gtm plugin on wordpress/woocomerce and it gets the following content:
cartContent: {
totals: {
applied_coupons: [],
discount_total: 0,
subtotal: "2844.715447",
total: "2844.715447"
},
items: [
{
id: "K-GG-V4-S",
name: "Grill Gazowy Koler Relish v4 5 palników 17,2kW",
sku: "K-GG-V4-S",
category: "Grille Gazowe",
price: 3499,
stocklevel: 41,
quantity: 1
},
{
id: "5900000002453",
name: "Fartuch Koler",
sku: "5900000002453",
category: "Wszystkie produkty",
price: 0,
stocklevel: null,
quantity: 1
},
{
id: "6600006666664",
name: "Pokrowiec + wąż i reduktor",
sku: "6600006666664",
category: "Wszystkie produkty",
price: 0,
stocklevel: null,
quantity: 1
}
]
},
but I have to implement the entire content of the basket into something that is to change dynamically depending on the number of products:
<script>
wph('track', 'AddToCart', {
content_type: 'category',
contents: [{
id: 'PRODUKT_ID1',
name: 'NAZWA_PRODUKTU1',
category: 'KATEGORIA_PRODUKTU1',
ean: 'PRODUKT_EAN_ID1',
price: 20.15,
in_stock: true
quantity: 1
weight : 'WAGA PRODUKTU'
}, {
id: 'PRODUKT_ID2',
name: 'NAZWA_PRODUKTU2',
category: 'KATEGORIA_PRODUKTU2',
ean: 'PRODUKT_EAN_ID2',
price: 20.15,
in_stock: true
quantity: 1
weight : 'WAGA PRODUKTU'
}]
})
</script>
How can I do this in GTM? I must admit that it was a bit too much for me, because I usually didn't need the entire basket.

Mongo $facet get and count the tags of the matched products in aggregation pipeline

I have this aggregation pipeline:
aggregate.lookup({
from: 'tags',
localField: 'tags',
foreignField: '_id',
as: 'tags'
});
aggregate.match({
productType: 'product',
available: true,
categories: {
$elemMatch: {
url: '/category/test'
}
}
});
aggregate.facet({
products: [
{ $sort: { [order]: sort } },
{ $skip: skip },
{ $limit: pageSize },
{
$project: {
_id: 1,
images: 1,
onSale: 1,
price: 1,
quantity: 1,
slug: 1,
sale: 1,
sku: 1,
status: 1,
title: 1,
brand: 1,
tags: 1
}
}
],
tags: [
{ $unwind: '$tags' },
{
$group: {
_id: {
name: '$name.label',
slug: '$slug'
},
count: {
$sum: 1
}
}
}
],
range: [
{
$bucketAuto: {
groupBy: '$price',
buckets: 1,
output: {
min: { $min: '$price' },
max: { $max: '$price' }
}
}
}
],
total: [{ $group: { _id: null, count: { $sum: 1 } } }]
});
aggregate.addFields({
total: {
$arrayElemAt: ['$total', 0]
}
});
aggregate.addFields({
range: {
$arrayElemAt: ['$range', 0]
}
});
Every product has it's own tags and I can't figure out how to:
Get the tags that belong only to the matched products and return an array from the $facet that contains
tags: [{name: 'tag1', slug: 'slug1', count: 10}, {name: 'tag2', slug: 'slug2', count: 5} ]
Where count: 10 are the products that have the tag.
Right now it returns all the tags found in the database.
2. Why the range property returns an object like this:
"range": {
"_id": {
"min": 5.9,
"max": 47
},
"min": 5.9,
"max": 47
}
and not like this since i provide an output object in $bucketAuto:
"range": {
"min": 5.9,
"max": 47
}
As of 2, this is normal mongodb behavior for $bucketAuto.

Here's what i've done and it works:
just right before $facet:
aggregate.lookup({
from: 'tags',
let: { tags: '$tags' },
pipeline: [
{
$match: {
$expr: { $in: ['$_id', '$$tags'] }
}
}
],
as: 'tags'
});
and then inside $facet:
tags: [
{ $unwind: { path: '$tags' } },
{
$group: {
_id: '$tags',
count: {
$sum: 1
}
}
}
],

Mongodb aggregate push with index value of array

I am stucked in one aggregate query, Following is my data
Let database = [
{
_id: 'fefesf', name: 'John', info: {date: ISODate(), marks: '12'}
},
{
_id: 'uiuioo', name: 'John', info: {date: ISODate(), marks: '15'}
},
{
_id: 'erygbo', name: 'Ben', info: {date: ISODate(), marks: '18'}
}]
and my aggregate query is
var query = [{
$group: {
_id: '$name',
Marks: {
$push: {
x: '$index', ..............(not working right now)
y: '$info.marks'
}
}
}
}]
Is it possible to get index of grouped document as 'x' while pushing it in 'Marks' array. Like Output should be
[
{_id: 'John', Marks: [{x: 1, y: 12}, {x: 2, y: 15}]},
{_id: 'Ben',{x: 1, y: 18}}
]
Thanks in advance.!

Since mongoDB version 3.6 you can use $reduce for that*:
db.collection.aggregate([
{
$group: {
_id: "$name",
Marks: {$push: {y: "$info.marks"}}
}
},
{$project: {
Marks: {
$reduce: {
input: "$Marks",
initialValue: [],
in: {$concatArrays: [
"$$value",
[
{
y: "$$this.y",
x: {$add: [{$size: "$$value"}, 1]}
}
]
]
}
}
}
}
}
])
See how it works on the playground example

How to reach contents of a nested JSON response body in javascript?

I need to automate some API tests with frisby.js, and I'm stuck at accessing to some data which is nested inside JSON response body.
Below is my code
var frisby = require('c:/frisby');
frisby.create('Request available Voyages')
.post('someURL', {
departureVoyage: {
from: "500",
to: "500",
date: '2017-01-07'}})
.inspectJSON()
.afterJSON(function (voyage) {
console.log(voyage.departureVoyage.voyages);}
Below is the output of inspectJSON() function
{ type: 'voyageResponseWsDTO',
departureVoyage:
{ date: '2017-01-07',
voyages:
[ { endTime: '22:30',
quotas:
[ { id: '8796095719239',
limit: 66,
name: 'PROMOTION',
price: '34',
priceCurrency: 'USD' },
{ id: '8796095620935',
limit: 271,
name: 'ECONOMY',
price: '51',
priceCurrency: 'USD' },
{ id: '8796095489863',
limit: 19,
name: 'BUSINESS',
price: '72',
priceCurrency: 'USD' },
{ id: '8796234721095',
limit: 0,
name: 'CAR PROMOTION',
price: '84',
priceCurrency: 'USD' },
{ id: '8796095752007',
limit: 2,
name: 'VIP',
price: '800',
priceCurrency: 'USD' } ],
time: '20:00',
vessel:
{ carriesVehicles: true,
TypeCode: 'FE',
TypeName: 'Ferry' } } ] } }
and below is the output of console.log(voyage.departureVoyage.voyages);
[ { endTime: '22:30',
quotas: [ [Object], [Object], [Object], [Object], [Object] ],
time: '20:00',
vessel:
{ carriesVehicles: true,
TypeCode: 'FE',
TypeName: 'Ferry' } } ]
My problem is, when I try to access content of "quotas" with "console.log(voyage.departureVoyage.voyages.quotas);" I get "undefined" message.
Do you know a way how can I reach data of this "quotas"? Because I need to reach properties of this "quotas", like id of one them.
Thanks

voyage.departureVoyage.voyages is an array, and quotas is in the first item of that array,
So refer it like below for quotas inside it,
voyage.departureVoyage.voyages[0].quotas
