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 !

How to perform multiple nested Lodash GroupBys on a tree like structure?

Say I have a data structure like so.
child: [
{
typeOfPackage: 'subSub',
parents: '/Test123/Diet/',
itemName: '250 ML',
pricePerItem: 150,
quantity: 0,
quantityType: '123',
description: '5',
avgTimeTaken: 0,
images: [],
isEnabled: true,
inventory: [],
equipment: [],
_id: 617f9efdf0347931684888fd
},
{
typeOfPackage: 'sub',
parents: '/Test123/',
itemName: 'Regular',
pricePerItem: 0,
quantity: 0,
quantityType: '1',
description: '1',
avgTimeTaken: 1,
images: [],
isEnabled: true,
inventory: [],
equipment: [],
_id: 617f9efdf0347931684888fe
},
{
typeOfPackage: 'subSub',
parents: '/Test123/Reg3/',
itemName: '500ML',
pricePerItem: 123,
quantity: 0,
quantityType: '12',
description: '123',
avgTimeTaken: 51,
images: [],
isEnabled: true,
inventory: [],
equipment: [],
_id: 617f9efdf0347931684888ff
}
]
I intend to transform this data by splitting parents. And my intended result looks as follows:
child: [
{
itemName: 'Test123',
subPackages: [
{
itemName: 'Diet',
subSubPackages: [{
typeOfPackage: 'subSub',
parents: '/Test123/Diet/',
itemName: '250 ML',
pricePerItem: 150,
quantity: 0,
quantityType: '123',
description: '5',
avgTimeTaken: 0,
images: [],
isEnabled: true,
inventory: [],
equipment: [],
}]
},
{
itemName: 'Regular',
typeOfPackage: 'sub',
parents: '/Test123/',
pricePerItem: 0,
quantity: 0,
quantityType: '1',
description: '1',
avgTimeTaken: 1,
images: [],
isEnabled: true,
inventory: [],
equipment: [],
subSubPackages: [],
},
{
itemName: 'Reg3',
subSubPackages: [
{
typeOfPackage: 'subSub',
parents: '/Test123/Reg3/',
itemName: '500ML',
pricePerItem: 123,
quantity: 0,
quantityType: '12',
description: '123',
avgTimeTaken: 51,
images: [],
isEnabled: true,
inventory: [],
equipment: [],
_id: 617f9efdf0347931684888ff
}
]
},
]
}
]
I tried using lodash's chain and groupBy but I could only get as far as grouping it by the first itemName (Test123). I could not figure out how to do further grouping inside that without using a custom for loop and map methods and that too confused me.

You could split parents and build a nested structure.
This approach takes an shadow object for a faster access to same named parents and returns only the payload without organizing structure.
If you like to use subPackages or subSubPackages, you could take a function for generating this key along with the actuyl nesting level. For later processing data, I recommend to use only generic names, like children for every level.
const
getSub = level => `sub${'Sub'.repeat(level)}Level`,
data = [{ typeOfPackage: 'subSub', parents: '/Test123/Diet/', itemName: '250 ML', pricePerItem: 150, quantity: 0, quantityType: '123', description: '5', avgTimeTaken: 0, images: [], isEnabled: true, inventory: [], equipment: [], _id: '617f9efdf0347931684888fd' }, { typeOfPackage: 'sub', parents: '/Test123/', itemName: 'Regular', pricePerItem: 0, quantity: 0, quantityType: '1', description: '1', avgTimeTaken: 1, images: [], isEnabled: true, inventory: [], equipment: [], _id: '617f9efdf0347931684888fe' }, { typeOfPackage: 'subSub', parents: '/Test123/Reg3/', itemName: '500ML', pricePerItem: 123, quantity: 0, quantityType: '12', description: '123', avgTimeTaken: 51, images: [], isEnabled: true, inventory: [], equipment: [], _id: '617f9efdf0347931684888ff' }],
result = data
.reduce((r, o) => {
o
.parents
.split('/')
.filter(Boolean)
.reduce((t, itemName, i) => {
if (!t[itemName]) {
t[itemName] = { _: [] };
t._.push({ itemName, [getSub(i)]: t[itemName]._ });
}
return t[itemName];
}, r)
._
.push(o);
return r;
}, { _: [] })
._;
console.log(result);
.as-console-wrapper { max-height: 100% !important; top: 0; }

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.

Mongoose, apply `.aggregate()` on array of subdocuments and get the result with other fields of document in least number of queries

This is my Mongoose Model:
const postSchema = new Schema({
user: {
type: Schema.Types.ObjectId,
ref: 'User',
required: true
},
caption: {
type: String
},
action: {
type: [{
actionName: {
type: String,
required: true
},
user: {
type: Schema.Types.ObjectId,
ref: 'User'
}
}],
default: []
},
shares: [{
type: Schema.Types.ObjectId,
ref: 'User'
}];
});
All I want is to have a mongodb query with or without using .aggregate() to get the user & caption field as it is but instead of action and shares I want their counts for a particular document.
Sample Document
{
_id: "fgsergehegoieofgesfglesfg",
user: "dfjksjdnfkjsdfkjsdklfjglkbj",
caption: "This is the post caption",
action: [
{
actionName: 'e1', user: "sdfasdsdfasdfdsdfac951e5c"
},
{
actionName: 'e1', user: "asdfmadfadfee103c9c951e5d"
},
{
actionName: 'e2', user: "op34937cdbae0cd4160bbec"
},
{
actionName: 'e2', user: "2543ebbasdfd1750690b5b01c"
},
{
actionName: 'e3', user: "asdfcfebdb5dd1750690b5b01d"
},
],
shares: ["ewrebdb5ddadsf5069sadf1d", "asdfsdfbb85dd1750690b5b01c", "fasec92dsfasde103c9c95df5d"]
};
Desired output after query:
{
_id: "fgsergehegoieofgesfglesfg",
user: 'dfjksjdnfkjsdfkjsdklfjglkbj',
caption: 'This is the post caption',
actionCount: [{ count: 1, actionName: 'e3' },
{ count: 2, actionName: 'e2' },
{ count: 2, actionName: 'e1' }],
shareCount: 3
}
I am able do get following results using .aggregate():
Query:
let data = await Test.aggregate([
{ $match: { _id: mongoose.Types.ObjectId("fgsergehegoieofgesfglesfg") } },
{ $unwind: "$action" },
{
$group: {
_id: "$action.actionName",
count: { $sum: 1 }
}
},
{
$project: {
_id: 0,
actionName: "$_id",
count: 1
}
}
]);
Result:
[
{ count: 1, actionName: 'e3' },
{ count: 2, actionName: 'e2' },
{ count: 2, actionName: 'e1' }
]
I just want to put this in the original document and get the result. Also, doing the same for share field. It would be better if this can be done in single query. I have tried using $replaceRoot along with $mergeObjects but don't know how to correctly use them. I am very new to mongodb and mongoose.
Please help. Thank you.

Since you're aggregating a nested array you need to run $grouptwice and $first can be used to preserve original document's field values:
await Test.aggregate([
{ $match: { _id: mongoose.Types.ObjectId("fgsergehegoieofgesfglesfg") } },
{ $unwind: "$action" },
{
$group: {
_id: { _id: "$_id", actionName: "$action.actionName" },
user: { $first: "$user" },
caption: { $first: "$caption" },
count: { $sum: 1 },
shareCount: { $first: { $size: "$shares" } }
}
},
{
$group: {
_id: "$_id._id",
user: { $first: "$user" },
caption: { $first: "$caption" },
shareCount: { $first: "$shareCount" },
actionCount: {
$push: {
actionName: "$_id.actionName",
count: "$count"
}
}
}
}
])

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
