I want to access my comments I tried the following code but it only returns reviews
exports.commentProduct = async (req, res, next) => {
const newproduct = await Product.find({});
try {
const reviews = newproduct?.map((p) => {
if (typeof p.reviews != "undefined") {
console.log(p.reviews);
}
});
const com = reviews?.map((c) => {
// console.log(comments);
});
// const comments = reviews.comment;
return res.status(200).json({
success: true,
reviews,
});
} catch (error) {
return res.status(500).json({
success: false,
message: error.message,
});
}
};
the Console Prints products having reviews but after applying dot notation on reviews I got undefined

Working with your example, you can map each item, then map the reviews, and get the comment out of each like using the following code
const data = [{
"_id": "63c4ee520ca7722674d007d5",
"product_name": "Headphones",
"product_description": "xvy",
"product_price": 8000,

data.map((dat) => {
dat["reviews"].map((rev) => {
document.querySelector('div').innerHTML +=rev["comment"]
})
})
<div></div>
I'm trying to retrieve the sum of some fields based on a search result and filter and I want to do the summation and apply it only to the search result
In my application based on nodejs and mongoose, I have a search process for the user's payment transaction records, which are divided into two parts, or filtered into two parts, which are the balance consumption records and the balance top-up records as follows
I do a filtering process through Query while searching and retrieving records. This is the result of the search
What I really want is to create a new dummy field that does not exist in the database, and it is included in the data returned from the request sent in the previous image, and it calculates the total points based on the search result
I found this code online and tried it
I tried to configure it to fit the data I had
This code returns the result separately from the search process that I intend to retrieve, and this is normal since it contains a different result
It also returns the result of collecting points for all users, and this is something I do not need
History.aggregate(
[{ $group: { _id: "$userId", total: { $sum: "$point"}}}],
function(err, result) {
if (err) {
res.send(err);
} else {
res.json(result);}});

and sample data like the following:

isActive:true
// and so many other fields
},
{
id:2,
"name": [
{"language": "en-US", "text": "Pen"}
],
isActive:true
// and so many other fields
}
I would like to update the document by Id:1 and change the text only for french, I tried by:
const input={ "id":"1", "isActive": false}
const name= { "name": [{"language": "fr-CA", "text": "Nouvel article"}]}
await langs.findByIdAndUpdate(
{ _id: input.id },
{ ...input, $addToSet: { name } },
{ new: true, upsert: true }
);
but the result is: (added another french item)
{
id:1,
"name": [
{"language": "en-US", "text": "Book"},
{"language": "fr-CA", "text": "livre"},
{"language": "fr-CA", "text": "Nouvel article"}
],
isActive:false
},
This is based on Brit comment:
https://mongoplayground.net/p/atlw5ZKoYiI
Please advise.
As long as that attribute already exists on the document, you can do something like:
Collection.findOneAndUpdate({id: 1}, {
$set: {
"name.$[elem]": name
}
},
{
arrayFilters: [ { "elem.language": name.language } ],
upsert: true,
new: true
})
I'm trying to group an array of objects. The array should be grouped following this quote:
Group by type respecting the sequence.
Array I wish to group
var arrayObj = [
{ "type": "user", "text": "user1" },
{ "type": "user", "text": "user2" },
{ "type": "user", "text": "user3" },
{ "type": "clerk", "text": "clerk1" },
{ "type": "user", "text": "user4" },
{ "type": "clerk", "text": "clerk2" },
{ "type": "clerk", "text": "clerk3" },
{ "type": "user", "text": "user5" },
{ "type": "user", "text": "user6" }
];
The way I want it to be grouped:
var newArray = [
[
{type: "user", text: "user1"},
{type: "user", text: "user2"},
{type: "user", text: "user3"}
],
[
{type: "clerk", text: "clerk1"}
],
[
{type: "user", text: "user4"}
],
[
{type: "clerk", text: "clerk2"},
{type: "clerk", text: "clerk3"}
],
[
{type: "user", text: "user5"},
{type: "user", text: "user6"}
]
];
What i tried:
I'm trying to use a filter, but without success since it even groups, but it groups all that are of the same type without respecting the sequence I want (from the array above);
var arrayObj = [
{ "type": "user", "text": "user1" },
{ "type": "user", "text": "user2" },
{ "type": "user", "text": "user3" },
{ "type": "clerk", "text": "clerk1" },
{ "type": "user", "text": "user4" },
{ "type": "clerk", "text": "clerk2" },
{ "type": "clerk", "text": "clerk3" },
{ "type": "user", "text": "user5" },
{ "type": "user", "text": "user6" }
];
var newArray = [];
newArray.push(filtrarArray(arrayObj, 'clerk'));
newArray.push(filtrarArray(arrayObj, 'user'));
console.log(newArray);
function filtrarArray(array, type) {
return array.filter(function (val) {
return val.type === type;
});
}
The snippet below first sorts the array by type, which then makes it easy to loop through and group. Let me know if this solves your problem :)
EDIT
Just realized you didn't need sorting, so I commented the sort function out, but it's always there to be uncommented if you change your mind :)
const arrayObj = [
{ type: 'user', text: 'user1' },
{ type: 'user', text: 'user2' },
{ type: 'user', text: 'user3' },
{ type: 'clerk', text: 'clerk1' },
{ type: 'user', text: 'user4' },
{ type: 'clerk', text: 'clerk2' },
{ type: 'clerk', text: 'clerk3' },
{ type: 'user', text: 'user5' },
{ type: 'user', text: 'user6' },
];
const group = ar =>
ar
// .sort((a, b) => (a.type < b.type ? -1 : 1))
.reduce((newAr, obj, i) => {
if (0 === i) return [[obj]];
if (obj.type === newAr[newAr.length - 1][0].type)
return newAr[newAr.length - 1].push(obj), newAr;
return [...newAr, [obj]];
}, []);
const groupedAr = group(arrayObj);
console.log(groupedAr);
function groupConsecutive(arrayObj) {
if (arrayObj.length === 0) {
return [];
}
let matchedTypesIndex = 0;
let newArray = [
[
arrayObj[0]
]
];
let currentType = arrayObj[0]["type"];
let i = 1;
while (i < arrayObj.length) {
if (arrayObj[i]["type"] === currentType) {
newArray[matchedTypesIndex].push(arrayObj[i]);
} else {
currentType = arrayObj[i]["type"];
newArray.push([]);
matchedTypesIndex++;
newArray[matchedTypesIndex].push(arrayObj[i]);
}
i++;
}
return newArray;
}
This is probably not best pure solution but works as you need.
var arrayObj = [
{ "type": "user", "text": "user1" },
{ "type": "user", "text": "user2" },
{ "type": "user", "text": "user3" },
{ "type": "clerk", "text": "clerk1" },
{ "type": "user", "text": "user4" },
{ "type": "clerk", "text": "clerk2" },
{ "type": "clerk", "text": "clerk3" },
{ "type": "user", "text": "user5" },
{ "type": "user", "text": "user6" }
];
let lastType;
let arr = [];
let arrIndex = -1;
arrayObj.forEach(obj => {
if(obj.type == lastType) { // add item into last group array by index
arr[arrIndex].push(obj);
}
else { // or add new group array
lastType = obj.type;
arrIndex++;
arr.push([obj]);
}
})
console.log(arr);
See This solution it will work
var arrayObj = [
{ type: "user", text: "user1" },
{ type: "user", text: "user2" },
{ type: "user", text: "user3" },
{ type: "clerk", text: "clerk1" },
{ type: "user", text: "user4" },
{ type: "clerk", text: "clerk2" },
{ type: "clerk", text: "clerk3" },
{ type: "user", text: "user5" },
{ type: "user", text: "user6" },
];
let typeNow = arrayObj[0].type;
let res = [];
let resultArray = [];
arrayObj.forEach((obj, i) => {
if (obj.type == typeNow) {
resultArray.push(obj);
} else {
resultArray = [obj];
res.push(resultArray);
typeNow = obj.type;
}
if (i == arrayObj.length - 1) res.push(resultArray);
});
console.log(res);
This is best solution can i have
It seem unordred because of Browser auto order but if you try in js file it will work and ordred
I'm responding with another way I found to solve my problem. This is just one more way I decided to comment.
Let's go:
I'm traversing the arrayObjects array using the appropriate loop for arrays for...of and then checking if the variable I set for arrayObjects (loopArrObj) has a different value of type of the variable (typeValue), if it is inserted at the end of the new array (grouping) using the array method push an empty array and then assign the value of the loopArrObj(Ie, there will be in the array grouping array empty only for the values that are different).
So far so good, we have the first empty array. Next I'm defining this empty array with the push method the loopArrObj object in question, then we get the value through the console. I'm removing 1 from grouping.lengh so the loop assigns from 0 and not 1.
var arrayObjects = [
{ "type": "user", "text": "user1" },
{ "type": "user", "text": "user2" },
{ "type": "user", "text": "user3" },
{ "type": "clerk", "text": "clerk1" },
{ "type": "user", "text": "user4" },
{ "type": "clerk", "text": "clerk2" },
{ "type": "clerk", "text": "clerk3" },
{ "type": "user", "text": "user5" },
{ "type": "user", "text": "user6" }
];
let typeValue,
grouping = [],
loopArrObj;
for (loopArrObj of arrayObjects) {
if (loopArrObj.type !== typeValue) {
grouping.push([]);
typeValue = loopArrObj.type;
}
grouping[grouping.length - 1].push(loopArrObj);
}
console.log(grouping);

});
return daily_entry
};
report_data tables schema
module.exports = function (sequelize, DataTypes) {
const report_data= sequelize.define('report_data', {
daily_entry : {
type: DataTypes.INTEGER(),
allowNull: true
},
Date: {
type: DataTypes.INTEGER(),
allowNull: true
},
report_document_id: {
type: DataTypes.TEXT,
allowNull: true
}
},
{
tableName: 'report_data'
});
return report_data
};
So, Where am I doing wrong and why I am getting entry_i as foreign key
