How can I sort data with Firebase?

How can I sort data with Firebase? - javascript

I am creating a little React application about Pokemons. I have in DB informations about all of them (about 900+).
They all contain an id field, which is an integer from 1 to 900+.
But the problem is when I do a request like this :
firebase.database().ref(`mydb`).orderByChild('id').startAt(1).limitToFirst(limit).once('value')
The results are not correct: I have an id array like this: [9,1, 10, 6, 4]
Am I doing something wrong ?
Edit:
I add the result I got when I perform the request I wrote above, I added a custom_id field containing ids as strings, but I stille have an unordered result:

You've not attached your database image, but with the order one thing is sure that these keys in your database are strings.
And when you order string data, it is ordered lexicographically.
So for numbers, this is the normal order:
1
9
10
But for strings, this is the normal order:
"9"
"1"
"10"
I don't think there is any operator in Firebase (nor in most other databases) to change this behaviour.
Instead, you will have to modify the data to get the behavior you want. So: store values that are in the order you need them when sorted lexicographically.
For numbers you can accomplish that by padding them with zeroes:
"001"
"009"
"010"
EDIT:
Now after Json, these values are stored in id field so the above thing does not apply to this.
You may however use a code like this, to do what you're trying:
mDatabase
.child("main_child")
.orderByChild("id")
.addValueEventListener(new ValueEventListener() {
public void onDataChange(DataSnapshot snapshot) {
for (DataSnapshot child: snapshot.getChildren()) {
System.out.println(child.getKey());
}
}

How to export nested json array to pdf using PDFMAKE Angular

I have used Angular as programming language for my project and i am a beginner. But i am stuck at the point where i have to generate PDF of my JSON response.
Looked at the documentation of PDFMAKE to achieve the same, but couldnot figure out how to implement it and come out with the output as shown in following image.

How to identify extracted obj file from response of autodesk model derivative API?

In Model Derivative API (OBJ Extraction using DbIds), I retrieved OBJ URN using API. As Response shows below, it returns all children's URN for obj, mtl, and its zip. How do we identify the recent extraction as every child does have its own guid?
I have attached whole response JSON. What I am looking for is the second obj file which has extracted using several dbids like "17,19,21,22,23...". The first child obj was created long ago. How do I differentiate the new obj. As GUID's are different for every node. How do I identify which GUID.obj belongs to my desired extraction.
** Edited **
I am looking for identifying extracted wavefronts object files( not objectids and name which gets from metadata). Suppose if I extracted 2 object files from one model, then after completion of object file geometry extraction job, 6 file gets generated and store in bucket.
first .obj (guid = /output/geometry/e72fa6b3-4fc2-3c86-8424-5d0755539c0d.obj)
first .mtl
first .zip
second .obj
second .mtl
second .zip
Every file does have different GUID.Type as name. and those guid's are random and never shown while calling of extraction API or while getting its progress.
these are shown in below JSON file. Now suppose I extracted 10 different object files from one model. that means in bucket 30 new file URN will be generated.
And it is getting very hard to identify.
The Solution could have been if I extract obj geometry from model, I should get that particular obj, mtl, zips guid. IF I am getting only 3 ids then I can map those and download it from bucket.
What is happening now is I am getting all obj's guid (suppose 30 ) after calling get manifest GET :urn/manifest . And I am not understanding what obj file belong to which extraction.

Use GET :urn/metadata to obtain a list of model views:
{
"data": {
"type": "metadata",
"metadata": [
{
"name": "Scene",
"role": "3d",
"guid": "4f981e94-8241-4eaf-b08b-cd337c6b8b1f",
},
{
"name": "Sheet: A101",
"role": "2d",
"guid": "8e7c6bca-cfd1-290e-4b16-f3670169bb71"
}
]
}
}
Then use GET :urn/metadata/:guid to retrieve the object tree to identify your derivatives:
{
"data": {
"type": "objects",
"objects": [
{
"objectid": 1,
"name": "A5",
"objects": [
{
"objectid": 2,
"name": "Model",
"objects": [
{
"objectid": 3,
"name": "Bottom",
"objects": [
{
"objectid": 4,
"name": "Box"
}
]
},

How to filter nested array with values from another nested array using array.filter and array.some etc

I have the following code which I am using to filter one nested array with values from another nested array, but I am looking for the more fastest method.
const length = this.addedStateItems.length;
for (let i = 0; i < length; i++) {
if (this.addedStateItems[i].cities.length > 0) {
const tempCity: Array<BWCity> = [];
for (let k = 0; k < addedStates.length; k++) {
for (let l = 0; l < addedStates[k].Cities.length; l++) {
const city = this.addedStateItems[i].cities.find(item =>
item.name.toUpperCase().split(' ').join('_') === addedStates[k].Cities[l].CityName
);
if (city) {
tempCity.push(city);
}
}
}
this.addedStateItems[i].cities = tempCity;
}
}
JSON sample is as below:
this.addedStateItems = [

unable to fetch data from skybiometry

I'm trying to fetch tid of a photo from SkyBiometry in a callback function as shown below, but it doesn't work.
function callback(data) {
drawFaces($("#conent_demo_image"), data.photos[0], true);
var tid = data.photos[0].tags[0].tid;
$("#tid").text(tid);
}
The html:
<div id="tid">
tid:
</div>

According to the source of SkyBiometry Demo it should be something like this:

Remove an object from an array

What is the way to remove an property named "itemType"from the below given object
?
{
"id": 19,
"cost": 10,
"items": 10,
"numbers": 10,
"status": false,
"hours": 10,
"itemType": {
"id": 16,
"name": "PC 350",
"description": "PC 350"
},
"typeid": 12
}
So that the final array should look like
{
"id": 19,
"cost": 10,
"items": 10,
"numbers": 10,
"status": false,
"hours": 10,
"typeid": 12
}

This is object not array. You can use delete like this
var obj = {
"id": 19,
"cost": 10,
"items": 10,
"numbers": 10,
"status": false,
"hours": 10,
"itemType": {
"id": 16,
"name": "PC 350",
"description": "PC 350"
},
"typeid": 12
}
delete obj.itemType;

Whether it is an object and you want to delete a property from it, or you have an array and want to delete a value, the way to delete is -
delete obj.itemType //object.
delete array[3] //delete 4th item from the array.
Note - the structure you have provided is not an array, its an object.
