I am trying to get count of unseen messages from object in lodash.
below is my object
[
"conversation_id": "5a88779b2321141f2864e484"
"messages": [
{
"message_id": "5a88779b2321141f2864e483",
"sender_uid": 2,
"receiver_uid": 1,
"created": "2018-02-17T18:42:35.252Z",
"status": 1,
"delivered": false,
"seen": true,
}
]
]
I want to get count of seen: false messages
You can use filter to get all see = false messages and then can check length
var users = {
"conversation_id": "5a88779b2321141f2864e484",
"messages": [
{ "message_id": "5a88779b2321141f2864e483","sender_uid": 2,"receiver_uid": 1,"created": "2018-02-17T18:42:35.252Z","status": 1,"delivered": false,"seen": true,},
{ "message_id": "5a88779b2321141f2864e483","sender_uid": 2,"receiver_uid": 1,"created": "2018-02-17T18:42:35.252Z","status": 1,"delivered": false,"seen": false },
{ "message_id": "5b88779b2321141f2864e483","sender_uid": 2, "receiver_uid": 1, "created": "2018-02-17T18:42:35.252Z", "status": 1,"delivered": false,"seen": false,}
]
}
var unseen_messages = _.filter(users.messages, message => { return !message.seen; }).length;
console.log(unseen_messages);
<script src="https://cdn.jsdelivr.net/lodash/4.13.1/lodash.min.js"></script>
Without lodash you can use reduce
var users = {
"conversation_id": "5a88779b2321141f2864e484",
"messages": [
{ "message_id": "5a88779b2321141f2864e483","sender_uid": 2,"receiver_uid": 1,"created": "2018-02-17T18:42:35.252Z","status": 1,"delivered": false,"seen": true,},
{ "message_id": "5a88779b2321141f2864e483","sender_uid": 2,"receiver_uid": 1,"created": "2018-02-17T18:42:35.252Z","status": 1,"delivered": false,"seen": false },
{ "message_id": "5b88779b2321141f2864e483","sender_uid": 2, "receiver_uid": 1, "created": "2018-02-17T18:42:35.252Z", "status": 1,"delivered": false,"seen": false,}
]
}
items = users.messages;
var totalCount = items.reduce((total, obj) => { return (!obj.seen) ? (total +1) : total }, 0);
console.log(totalCount);
_.sumBy would do the trick
const unseenMessages = _.sumBy(users.messages, message => message.seen === false);

i'm using the node.js client library of google transcoder api. I'm able to retrive a paginated list of some jobs, but i'm not able to order elements by start date. Here my codes:
const { TranscoderServiceClient } = require('#google-cloud/video-transcoder').v1;
class TranscoderApiController {
constructor() {
this.projectId = process.env.GOOGLE_CLOUD_PROJECT;
this.location = process.env.TASK_LOCATION;
}
async getEntries(req, res, next) {
const params = {
pageSize: req.query.pageSize ? parseInt(req.query.pageSize) : 10,
pageToken: req.query.pageToken,
filter: req.query.filter,
orderBy: req.query.orderBy
}
const client = new TranscoderServiceClient();
const result = await client.listJobs({
parent: client.locationPath(this.projectId, this.location),
pageSize: params.pageSize,
orderBy: 'createTime.seconds'
}, {
autoPaginate: false
});
if (result.length == 3 && result[2] != undefined) {
return result[2];
} else {
return result[1];
}
}
}
module.exports = new TranscoderApiController();
When i call the getEntries method i receive the following error:
"3 INVALID_ARGUMENT: The request was invalid: sort order \"createTime.seconds\" is unsupported"
If i remove the orderBy: 'createTime.seconds' line then the api works but is not ordered as i want. The result is something like that (i abbreviate the json):
{
"jobs": [
{
"labels": {},

}
As you can see each job have the startTime.seconds property. I follow the syntax described here:
https://google.aip.dev/132#ordering
Any support to solve the ordered issue is appreciated.
I want to scan dynamodb using filter on product_id showing in below json of table.
Can anybody explain how to do scanning using filter of product_id.
Wants to scan dynamodb table data using documentclient.

I have tried the following set of code but it is returning empty array list
var params = {
TableName: "dev-agrowave-mandi-management",
// Select: "ALL_ATTRIBUTES"
FilterExpression: "contains(#product,:product)",
ExpressionAttributeNames: {
"#product": "product",
},
ExpressionAttributeValues: { ":product": {"product_id":parseInt(id)}
}
};
let lastEvaluatedKey = 'dummy'; // string must not be empty
const itemsAll = [];
while (lastEvaluatedKey) {
const data = await docClient.scan(params).promise();
itemsAll.push(...data.Items);
lastEvaluatedKey = data.LastEvaluatedKey;
if (lastEvaluatedKey) {
params['ExclusiveStartKey'] = lastEvaluatedKey;
}
}
return {msg:itemsAll,params:params};
Can the columns of a second leftJoinAndMapOne() be 'filtered' so that it only returns the columns or values that I need inside the object?
Query Builder:
const favorites = await this.favoritesRepo.createQueryBuilder('favorite')
.where('favorite.user_id = :token', { token })
.leftJoinAndMapOne('favorite.item', 'favorite.item_id', 'items')
.select(['favorite.id'])
.addSelect([
'items.title',
'items.description',
'items.price',
'items.stock',
])
.leftJoinAndMapOne(
'items.photos',
PhotosEntity,
'photos',
'favorite.item_id = photos.subject_id and photos.subject_type = :item',
{item: 'item'}
)
return paginate<Favorite>(favorites, options)
Output (GET):
//...

"price": 250.99,
"stock": 10,

Any suggestions or changes that I should make to make the output as expected? 🤔
.leftJoinAndMapOne(
'items.image',
PhotosEntity,
'photos',
'favorite.item_id = photos.subject_id and photos.subject_type = :item',

.addSelect('photos.url')
I tried with .select () or .addSelect () but it doesn't filter columns from photos.
I already resolved it

const favorites = await this.favoritesRepo.createQueryBuilder('favorite')

I'm trying to update the values of my payments array objects
{
"balance": 109610,
"gifts": [],
"orders": [],
"payments": [{
"isPaid": 0,
"status": "Pending",
"address": "3KsdQbmADyz1KNN7qqX1yZcMXBbfFCm31r",
"date": 1624057559970
}, {
"isPaid": 0,
"status": "Pending",
"address": "3FYQK6YiAaL8fEbDWaXYw38CJN3K2y5dPD",
"date": 1624058531601
}],
"isVendedor": false,
"isAdmin": true,
"createdAt": {
"$date": "2021-06-17T21:10:15.020Z"
},
"username": "teste",
"email": "teste#teste.com",
"password": "$2a$10$qUNkorDuvbf.AYLTvjNc4ebKyNgLa7L9NoTBwAIV8.BfN51umaD9O",
"__v": 3
}
First, I look for the object of the user who made a request to my server
const userPayment = await User.find({"payments.address": notification.address}).exec();
Then I go through the user object and find it until I find the position where I find notification.address again
userPayment.forEach((AllPayments, index) => {
AllPayments.payments.forEach((payment, index) => {
if (payment.address == notification.address) {
if (payment.isPaid || payment.status != "Pending")
return res.json({
success: false,
error: "Payment Already Processed!",
});
const valueToDeposit = Math.round(notification.fiat_amount);
console.log(
userPayment[0].payments[index].isPaid,
userPayment[0].payments[index].status
);
// Set payments[index].isPaid = true
// Set payments[index].status = "Paid"
});
});
So I tried to make these 3 ways and none of them was successful.
userPayment[0].balance += valueToDeposit; // this works when save() is triggered
userPayment[0].payments[index].isPaid = 1; // this doesnt works when save() is triggered
userPayment[0].payments[index].status = "Paid"; // this doesnt works when save() is triggered
userPayment[0].updateOne({"payments.address": notification.address}, { $set: { "payments.$.isPaid": 1,"payments.$.status":"Paid" } },(err, result) => { console.log(err, result); }); this doesnt works
userPayment[0].save()
i am getting data list from controller to ajax function to my datatable.all works well but my question is, I want to get one of list property to textbox and other values to datatable columns.for example:
list= TotalAMount,PAidAmount,RemAmount
and datatable
Totalamount| PaidAMount | RemAmount| ---------??
20 | 4 | 16 |
so this works fine but i want to get TotalAmount value to some textbox also like textbox=20.

`
