How Can I Query the Parent Record Using Javascript

Click here for picture Overview of the classes/entities
Hi guys, It could be great if someone could re-code and help me on this.I am new in D365 and JS. Basically, how can I query the parent to case_adjustment from adjustment invoice record using JS. I have provide my current code, please help me to review it. I have try everything but so far no luck. Sorry for my unprofessional picture. But I hope you understand it and could help me to code for this situation.
I have try to enable the debugger and it shows that the code cant run the adjustmentTypeLookup. and thats why it cant pass the value to retrieveRecord .Thank you.
function adjustmentInvoiceApproveAmount(executionContext) {
try {
// Get the form context
const formContext = executionContext.getFormContext();
// Extract attribute values from the form
const adjustmentAmount = formContext.getAttribute("case_adjustmentamount").getValue();
const amountDue = formContext.getAttribute("case_amountdue").getValue();
const adjustmentTypeLookup = formContext.getAttribute("case_adjustmenttype").getValue();
// Exit as adjustmenttype is not set
if (!adjustmentTypeLookup) return;
// Extract the adjustment type record ID from the payment type lookup
const adjustmentTypeId = adjustmentTypeLookup[0].id.substring(1, 37);
//console.log("GUID \"case_adjustmenttype\" = " + adjustmentTypeId + " ; " + typeof adjustmentTypeId);
//console.log(adjustmentTypeId);
// Retrieve a SINGLE case_adjustmenttype based on lookup ID on form
Xrm.WebApi.retrieveRecord("case_adjustmenttype", adjustmentTypeId, "$select=case_name").then(
function success(adjustmentType)
{
// If the payment type is credit notes then check payment amount and resit amount
if (adjustmentType.case_name.toLowerCase() == "Credit notes".toLowerCase())
{
if (adjustmentAmount >= amountDue) {
formContext.getEventArgs().preventDefault();
Xrm.Navigation.openErrorDialog({message:"Payment Amount cannot be more than Resit Amount."})
}
}
//Otherwise do nothing
},
function (error)
{
console.log(error.message);
}
);
}
catch (error)
{
console.log(error);
}
}

Firebase Function admin.database() null parameter in a transaction

I'm using Firebase Functions with the "Spark Plan" (free). This is part of my function:
return query.once("value").then(function(snapshot) {
snapshot.forEach(function(childSnapshot) {
var childData = childSnapshot.val();
if (childData.displayName === ally) {
existAlly = true;
console.log('uid: '+uid)
var ref = admin.database().ref('users/'+uid).transaction(function (current_value) {
console.log('current_value: '+uid)
current_value.mainAlly = ally;
current_value.coins = (current_value.coins || 0) + 10
return current_value;
}).then(() => {
console.log('New Ally added');
return true;
});
...
Here the logs, you can see "'current_value: null'
But, ss you can see in the next picture, the "ref" is correct:
So, is it a billing issue? The "admin.database()" stops working after a while? Or is it something else?
Thanks!
EDIT: I just did another test, and now the error is in "coins", with the same code:

Everything is working as expected. When working with transactions, you can expect that your handler function will get called the first time with null (which you will have to check for), then again with the actual contents of the database. You should review the documentation, and pay special attention to the note that says:
Transaction Function is Called Multiple Times
Your transaction handler is called multiple times and must be able to
handle null data. Even if there is existing data in your database it
may not be locally cached when the transaction function is run.

How do I reject writing value to Firebase if have the same value in my DB? (Javascript)

I'm creating my custom order id with auto-increment generator function for my project. I will state my question here, if you want to know the whole story please read below.
As written in the title, I need a way to reject my set to Firebase and it has to be done in 1 query. Currently, it will write my orderID to Firebase without rejecting it. But I need to reject if there is the same ID in the table.
The short version of my code will be posted here, the whole function will be posted below.
firebase.database().ref('orderCounter/orderIDsChecker/'+orderID).set({
id: orderID,
}, function(error) {
if (error) {
console.log('Order ID fail to generate. Regenerating new ID')
createOrderID(orderCounterRef);
} else {
console.log('Order ID created!')
}
});
}
The story,
I'm creating my own custom order id with auto-increment generator function for my project. The problem is that if multiple users creating order at the same time, it will generate the same id. Yes, I can use transaction() to solve the problem but I have no idea how to use it. Therefore, I have created my own version of the "transaction". With my method, I am able to prevent duplicates id unless 2 or more users create order within 1 second of gap. Or if anyone is kind enough to show me an example of how to write a transaction for my function, I thank you in advance.
The flow of the code is,
Get "currentMonth" and "orderIdCounter" from Firebase -> orderIdCounter +1 and update to Firebase -> start the process of generating order id -> Send the generated id to firebase -> If return success "order ID created", If not "got duplicate id" Re-run the whole process.
Below is the code for my order id generator function.
function createOrderID(orderCounterRef){
var childData = [];
var orderID;
//Get the Current Month and Order ID Counter from Firebase
orderCounterRef.on('value', function(snap) { childData = snapshotToArrayWithoutID(snap); });
var currentMonth = childData[0];
var orderIDCounter = childData[1];
if (orderIDCounter !== undefined){
//Update orderIDCounter on Firebase.
//This is to prevent duplicate orderID when multiple users is creating order at the same time.
var IDCounter = parseInt(orderIDCounter) + 1;
//Set IDCounter to 3 digits
IDCounter = ('00' + IDCounter.toString()).slice(-3);
firebase.database().ref('orderCounter/orderIDCounter').set(IDCounter);
//Handle the process to generate Order ID. Return in YYMMxxx(auto increment) format.
orderID = handleCreateOrderID(currentMonth, (parseInt(orderIDCounter) - 1));
//Check if duplicate ID on firebase
firebase.database().ref('orderCounter/orderIDsChecker/'+orderID).set({
id: orderID,
}, function(error) {
if (error) {
console.log('Order ID fail to generate. Regenerating new ID')
createOrderID(orderCounterRef);
} else {
console.log('Order ID created!')
}
});
}
return orderID;
}
My DB:

You should indeed use a transaction as you have mentioned in your question.
The following should do the trick:
//Declare a function that increment a counter in a transaction
function createOrderID() {
var orderIdRef = firebase.database().ref('orderId');
return orderIdRef.transaction(function(currentId) {
return currentId + 1;
});
}
//Call the asynchronous createOrderID() function
createOrderID().then(function(transactionResult) {
console.log(transactionResult.snapshot.val());
});
If you want to start the counter at a specific value, just create an orderId node in your database and assign a specific value to it, e.g; 1912000.
If you just want to start at 1, you don't need to create a node, it will be automatically created with the first call to the createOrderID() function.

Thank you, #samthecodingman & #Renaud Tarnec for your advice.
I took #samthecodingman's code and change a bit to fit my project. But I use generateOrderID() only to call the result and it works well. But you won't get any value with just the code. I call out another function (connectToFirebase) whenever users enter the page. I am not sure why it works or if this is the right way, but it works for me and that's good enough.
export function generateOrderID(){
var orderId;
var childData = [];
const orderCounterRef = firebase.database().ref('orderCounter/');
//Get the Current Month from Firebase
orderCounterRef.on('value', function(snap) { childData = snapshotToArrayWithoutID(snap); });
//Check ID format YYMMXXX (XXX=auto_increment). Hanlde auto_increment for Year and Month
handleOrderIdFormat(childData[0], orderCounterRef)
//transaction
orderCounterRef.child('orderId').transaction(function(currentId) {
orderId = (currentId||0) +1;
return orderId;
}, function(err) {
if( err ) {
console.log(err)
}
});
return orderId;
}
export function connectToFirebase(){
//Connection Firebase Database
const orderCounterRef = firebase.database().ref('orderCounter/');
orderCounterRef.on('value', function(snap) { });
}

Write an uploads metadata with information stored data in Firebase DB

I've been hitting my head against the wall on this for about 2 hours and I think I've just lost sight of the problem a bit.
I have an incremental field saved as "index" that upon a file upload starting has it's value increase by 1.
I am able to query the database and pull the value for index to the console and receive the updated value.
I can't for the life of me work out how to insert the value I've created and subsequently logged to the console (definitely doesn't need to be logged just did this to prove to myself I wasn't going insane) into the uploads metadata at the next stage of the script. I have tried everything I can think of - I've watched about an hour of youtube videos, and I can safely say beyond a shadow of a doubt I could turn my app into a running counter of peoples file uploads but I can't add it to their upload metadata!
Help me stack overflow you're my only hope!
Code below hopefully outlines the issue - the query is going into the variable indexRef but the actual info I need is in the nested variable "key" which is just the data snapshot value. This seems like it should be so easy.
var indexRef = firebase.database().ref('index');
indexRef.once('value')
.then(function(snapshot){
var key = snapshot.val()
console.log(key)
})
var imagekey = firebase.database().ref('images/').push().key;
var downloadURL = uploadTask.snapshot.downloadURL;
var updates = {};
var postData = {
url: downloadURL,
score: 1500,
index: indexRef,
user: user.uid
};
updates ['/images/'+imagekey] = postData;
firebase.database().ref().update(updates);
Thanks in advance and I apologise if the answer to this is trivial and I've wasted someones time!

Remember the then method returns promises https://firebase.googleblog.com/2016/01/keeping-our-promises-and-callbacks_76.html
var indexRef = firebase.database().ref('index');
// Declare variables outside of block to access within
var imagekey = firebase.database().ref('images/').push().key;
var downloadURL = uploadTask.snapshot.downloadURL;
var updates = {};
indexRef.once('value')
.then(function(snapshot){
var key = snapshot.val()
// Return key variable for use
return key;
})
.then(function(key){
// You can now access the key variable in here
var postData = {
url: downloadURL,
score: 1500,
index: key,
user: user.uid
};
updates ['/images/'+imagekey] = postData;
firebase.database().ref().update(updates);
})
Hope this helps you

Meteor setInterval and query

I want to have a function that checks every 5 seconds for all entries in database for some value is false and if finds then checks some logic condition and changes the value to true if the logic condition is met.
My function works well until I have something with isItReady: false in my collection. When I don't have, it obviously doesn't find anything and I start getting errors.
How should I do this correctly? I don't want to stop my interval because maybe something will be entered into the collection soon and then my inverval is stopped?
How can I do something like this:
If nothing matches my search criterea - productDate = Products.findOne({isItReady: false}); the interval is stopped and as soon as something new gets inserted I will start the inverval again?
var logicCheck = Meteor.setInterval( function () {
productDate = Products.findOne({isItReady: false}); //query to find all entries with isItReady: false
var timeNow = Date();
var timeCreated = productDate.startOfCountdown;
timeCreated = timeCreated.toString(); //converts timeCreated from object to String(in Mongo its a object)
var productId = productDate._id;
console.log(typeof timeNow) //string
console.log(typeof timeCreated) //string
console.log(timeNow + "timeNow")
console.log(timeCreated + "timeCreated")
if (timeCreated <= timeNow) {
console.log("check") //this works well
Products.update({_id: productId}, {$set: {isItReady: true}}, function(error, result) {
console.log(productId) //all good
if (error){
console.log(error.reason) //check the error
} else{
console.log("File with the id: " + result + " just get update")
}
});
}
}, 5000);

Your approach of polling MongoDB every 5 seconds is very non-Meteoric. You'd be much better off creating a Tracker.autorun function to instantly react to any product that has isItReady == false
For example:
Tracker.autorun(function(){
var notReadyProducts = Products.find({ isItReady: false });
notReadyProducts.forEach(function(p){
if ( your logic ... ) Products.update({ _id: p._id },{ $set: { isItReady: true }});
});
});
This assumes by the way that you're publishing (on the server) and subscribing to (on the client) a set of Products that is going to include these not ready products.
With this pattern no code will be running 99.99% of the time and then at the precise moment that a product is made not ready this code will kick in.
