How to save updated an embedded picklist selection on a custom Lightning Datatable?

I am using a 'Custom Datatable' solution in order to modify picklist values within a datatable. Project code may be referenced here:
https://live.playg.app/play/picklist-in-lightning-datatable
I have made changes so that I can retrieve data from the custom object: Payment__c, and I am attempting modify the picklist values for the Payment_Status__c field. My 'debugging' method has been to create numerous console.log statements to verify data during the updating process. Picklist values are currently hardcoded (have not figured out how to dynamically pull from SF yet). Inline edit of individual cells works fine, and I am able to save those values as well (though changes are not reflected until I perform a manual page refresh). Picklist selection is working, but I am unable to save the currently selected picklist value in the datatable.
I believe that the intended trigger event for picklist selection changes--'valueselect', is not being fired, and the handleSelection method is not receiving this event when a new picklist selection is made.
The lightning component used on Salesforce is c-customDatatableDemo:

As this is my first time working with Lightning Web components, I would greatly appreciate any assistance you may provide. Thanks in advance.

I was able to get this custom data table component working for something I am developing to effectively bind records as rows. Here 2 differences I notice:
I did not include onvalueselect and oncellchange methods for the component html declaration, only the onpicklistchanged.
You may want to use your custom server side controller method instead of the built-in uiRecordApi->updateRecord one. Something tells me this may not play nice with row data from the data table. In my implementation, I was simply able to pass the draftValues over to the server side method which has a single parameter of list of sObject:
async saveRecords(event){
const updatedFields = event.detail.draftValues;
this.draftValues = [];
this.showSpinner = true
try{
await saveRelatedRecords({sObjs: updatedFields}) // server side save
.then((result) => {
this.updateMessage = result;
})
this.showSpinner = false;
if(this.updateMessage == 'success'){
this.showToast('Success', 'Record(s) Updated', 'success');
} else{
this.showToast('Error', this.updateMessage, 'error');
}
await refreshApex(this._wiredRecordData);
this.unsavedData = this.records;
} catch (error) {
this.showSpinner = false;
this.showToast('Error while updating or refreshing records', error.body.message, 'error');
}
}
In regards to your data not refreshing, I suggest you wire your getPayments method so that you can always get a fresh set from the server side, rather than trying to keep track of and maintain data changes on the client side, something like:
_wiredRecordData;
#wire(getRelatedRecords)
relatedRecords(getRecsResult){
const { data, error } = getRecsResult;
this._wiredRecordData = getRecsResult;
if(data){
this.records = data;
}
}
Then after your success toast in your save method, you can use
await refreshApex(_wiredRecords); and lwc knows to rerender based on the wiring (or at least I think that's how it works.)
Lastly, here is the server side controller method I have to dynamically generate column header information so it does not need to be hard coded into the component. However I did need to modify the custom component a bit to include a new "fieldapi" attribute so that the client side method knows what field to set for the changed value during the onpicklistchanged action.
#AuraEnabled(cacheable=true)
public static String getColumnHeaders(String sObjAPI, String fieldAPIs)
{
List<ColumnHeaderInfo> colHeaders = new List<ColumnHeaderInfo>();
Schema.DescribeSObjectResult sObjDesc = Schema.getGlobalDescribe().get(sObjAPI).getDescribe();
Boolean objIsUpdateable = sObjDesc.isUpdateable();
Map<String, Schema.SObjectField> objFields = sObjDesc.fields.getMap();
for(String field: fieldAPIs.split(','))
{
if(!objFields.keySet().contains(field.toLowerCase())){
continue;
}
Schema.DescribeFieldResult fieldDesc = objFields.get(field).getDescribe();
if(!fieldDesc.isAccessible()){
continue;
}
ColumnHeaderInfo colHeader = new ColumnHeaderInfo();
colHeader.label = fieldDesc.getLabel();
colHeader.fieldName = fieldDesc.getName();
colHeader.editable = fieldDesc.isUpdateable() && sObjDesc.isUpdateable();
colHeader.type_x = fieldDesc.getType().name().toLowerCase();
if(colHeader.type_x == 'picklist')
{
colHeader.type_x = 'picklist';
List<Schema.PicklistEntry> picklistValues = fieldDesc.getPicklistValues();
colHeader.typeAttributes = new TypeAttributes();
colHeader.typeAttributes.options = new List<Option>();
for(Schema.PicklistEntry ple: picklistValues)
{
Option opt = new Option();
opt.value = ple.getValue();
opt.label = ple.getLabel();
colHeader.typeAttributes.options.add(opt);
}
colHeader.typeAttributes.context = new FieldName();
colHeader.typeAttributes.context.fieldName = 'Id';
colHeader.typeAttributes.value = new FieldName();
colHeader.typeAttributes.value.fieldName = fieldDesc.getName();
colHeader.typeAttributes.fieldapi = fieldDesc.getName();
}
// multi-select picklist fields not supported so make them read-only
if(colHeader.type_x == 'multipicklist'){
colHeader.editable = false;
}
colHeaders.add(colHeader);
}
return JSON.serialize(colHeaders).replaceAll('type_x', 'type');

Default value in Select field

I am confused about why I am getting this specific malfunction, I am unable to get a default value for my select dropdown list. My goal is to have "Choose Board" as the default but despite many trials, I have been unable to get this as the default value.
I have attempted a variety of solutions: AngularJS - Set default value on select inside a ng-repeat & How to have a default option in Angular.js select box
Without any luck.
My HTML Tags:
<select name="boardInput" class="form-control"
ng-required="true"
ng-init="form.boardInput = boards[0]"
ng-model="form.boardInput"
ng-options="board.name for board in boards">
</select>
My JS controller code
//TRELLO CONTROLLER
$scope.baseBoards =[{
id: false,
name: "Choose Board"
}];
$scope.getBoards = function() {
trello.getBoards('me', function(error, boards){
if(error){
log("Could Not Get Boards: ", error);
} else {
log("found " + boards.length + " boards");
$scope.boards = $scope.baseBoards.concat(boards);
}
});
};
The result is a field being added and set as the default, in the above code the null field disappears after any of the others are selected.
any help is much appreciated.

Try
<select name="boardInput" class="form-control"
ng-required="true"
ng-model="form.boardInput"
ng-options="board.name for board in boards">
</select>
and in your Controller
$scope.form.boardInput = "Choose Board"
If it works then you can replace the text with your desired variable such as $scope.baseBoards[0].name.

Please check this updated answer. For now your trello.getBoards I have commented, once you add it in your code, uncomment it and comment var boards this variable.
var app = angular.module('app', []);
app.controller('myController', ['$scope', function($scope) {
$scope.boards = [];
$scope.baseBoards = [{
id: false,
name: "Choose Board"
}];
$scope.getBoards = function() {
/* trello.getBoards('me', function(error, boards) {
if (error) {
log("Could Not Get Boards: ", error);
} else {
log("found " + boards.length + " boards");
$scope.boards = $scope.baseBoards.concat(boards);
}
}); */
//You will get boards data from your trello.getBoards method but I dont have access it so declaring local variable.
var boards = [{
name: 'one'
}, {
name: 'two'
}, {
name: 'three'
}]
$scope.boards = $scope.baseBoards.concat(boards);
};
}]);
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.7.5/angular.min.js"></script>
<div ng-app='app' ng-controller='myController' ng-init="getBoards()">
<select name="boardInput" class="form-control" ng-required="true" ng-init="form.boardInput = boards[0]" ng-model="form.boardInput" ng-options="board.name for board in boards">
</select>

NativeScript: UI won't show removed item from an ObservableArray without refresh

First of, I'm very new to NativeScript. I followed a tutorial for a ToDo list found here https://x-team.com/blog/build-simple-todo-list-mobile-application-nativescript/, and as a little exercise for myself I wanted to add a remove function for the tasks inside a list.
Here's my code:
Tasks.xml
<Page xmlns="http://schemas.nativescript.org/tns.xsd" navigatingTo="onNavigatingTo">
<Page.actionBar>
<ActionBar title="Tasks">
<ActionBar.actionItems>
<ActionItem text="New" tap="{{ insert }}" ios.position="right" />
<ActionItem text="Delete" tap="{{ delete }}" ios.position="right" />
</ActionBar.actionItems>
</ActionBar>
</Page.actionBar>
<ListView items="{{ tasks }}"></ListView>
tasks-view-model.js
var Observable = require("data/observable").Observable;
var ObservableArray = require("data/observable-array").ObservableArray;
var Sqlite = require("nativescript-sqlite");
var Dialogs = require("ui/dialogs");
function createViewModel(database, listId) {
var viewModel = new Observable();
viewModel.tasks = new ObservableArray([]);
viewModel.listId = listId;
viewModel.insert = function() {
Dialogs.prompt("Task Name", "").then(result => {
database.execSQL("INSERT INTO tasks (list_id, task_name) VALUES (?, ?)", [this.listId, result.text]).then(id => {
var _string = "ID: " + id + ", " + result.text;
this.tasks.push(_string);
}, error => {
console.log("INSERT ERROR", error);
});
});
}
viewModel.select = function() {
this.tasks = new ObservableArray([]);
database.all("SELECT id, task_name FROM tasks WHERE list_id = ?", [this.listId]).then(rows => {
for(var row in rows) {
var _id = rows[row][0];
var _item = rows[row][1];
var _string = "ID: " + _id + ", " + _item;
this.tasks.push(_string);
}
}, error => {
console.log("SELECT ERROR", error);
});
}
viewModel.delete = function() {
Dialogs.prompt("Task ID", "").then(result => {
database.execSQL("DELETE FROM tasks WHERE id = ?", [result.text]).then(id => {
Dialogs.prompt(id);
}, error => {
console.log("DELETE ERROR", error);
});
});
}
viewModel.select();
return viewModel;
}
exports.createViewModel = createViewModel;
The actual deleting of the item when passing its ID works fine. However the UI doesn't show this change without me manually refreshing it, and I cannot figure out why. In case it matters, I'm running this on an Android emulator.
Thanks in advance for your help.

Inside your delete function you also need to remove the item from the ObservableArray.
viewModel.delete = function() {
Dialogs.prompt("Task ID", "").then(result => {
database.execSQL("DELETE FROM tasks WHERE id = ?", [result.text]).then(id => {
Dialogs.prompt(id);
/// remove the item from the observable array.
this.tasks.splice(INDEX_OF_THE_ITEM_DELETED,1);
}, error => {
console.log("DELETE ERROR", error);
});
});
}
You may want to consider changing the ObservableArray of tasks from an array of strings to an array of Objects with an id property and value property. So it's easier to determine the index of the item you want to remove. If not you will have to rebuild value that is pushed into the array to find the index.

Using Laravel Mentions (at.JS and Laravel) to return A username and their ID

I'm currently building a comment system and would like to include the ability to mention users and tag them, subsequently I would like the tag to have a link to their profile (In this example, it's just /profile/{id})
I am currently using Laravel Mentions to generate the auto filled list from my Users Model. I'm doing it like:
function enableMentions(elem, type, column) {
$(elem).atwho({
at: "#",
limit: 5,
displayTpl: '<li><span>${name}</span></li>',
insertTpl: '${name}',
callbacks: {
remoteFilter: function(query, callback) {
if (query.length <= 1) return;
$.getJSON("/api/mentions/" + type, {
q: query,
c: column
}, function(data) {
callback(data);
});
}
}
});
}
// My api/mentions route: Route::get('/api/mentions/{type}', 'ApiController#index');
//My api controller:
public function index($type, Request $request)
{
try {
$resultColumns = [];
$query = $request->get('q');
$column = $request->get('c');
$model = app()->make(config('mentions.' . $type));
$records = $model->where($column, 'LIKE', "%$query%")
->get();
foreach ($records as $record) {
$resultColumns[] = $record->$column;
}
return response()->json($resultColumns);
} catch (\ReflectionException $e) {
return response()->json('Not Found', 404);
}
}
And finally, initializing the at.js
<script type="text/javascript">
$(function(){
enableMentions("#mention-commentContent", "users", "Username");
});
</script>
<div contentEditable="true" id="mention-commentContent" class="user-form" name="commentContent" type="text"></div>
I'm confused on how I can modify the above to return the username and the ID assigned to them, that way I can change the ${name} to ${id} and have it link through to their profile, right?

This package may help Laravel Mentions or this .
The basic idea is getting the usernames from the database via JSON , here is how they are using it in laracasts:
$("textarea#body").atwho({
at: "#", limit: 5, callbacks: {
remoteFilter: function (t, e) {
t.length <= 2 || $.getJSON("/api/users", {q: t}, function (t) {
e(t)
})
}
}
})

Dgrid formatter create column based on values in another column

I am creating a dgrid based on a data source which has an address and two columns with Boolean values which identifies what type of address is in the record, either postal address or business address.
I would like to display a descriptive name for the Boolean values in another column (Address Type) based on the two Boolean columns. I am trying to use the dgrid formatter function however i am unable to get the desired results. Under is my code:
Javascript
function getAddressType(){
$.each(employeeAddressData, function(key, value){
if(key == "postalAddress"){
if(value == true || value == 'true'){
console.log('returning postal');
return 'Postal';
}
}else{
console.log('returning business');
return 'Business';
}
});
}
var Employer = [{id: 1, businessName:'John Doe and Sons Limited',phone:'123456',address:'123 Long Street', postalAddress:true, businessAddress:false},
{id: 1, businessName:'Alice and Bob Limited',phone:'78956', address:'56 Short Street', postalAddress:false, businessAddress:true}];
var employerGrid = new CustomGrid({
store: employerStore,
columns:{
id:{
label:"Id",
field:"id",
hidden:true
},
businessName:{
label:"Business",
field:"businessName",
},
phone:{
label:"Contact No.",
field:"phone",
},
address:{
label:"Address",
field:"address",
},
addressType:{
label:"Address Type",
formatter:getAddressType();
}
},
selectionMode:"none",
loadingMessage: "Loading data...",
noDataMessage: "No results found....",
allowSelectAll: true
}, "employerGrid");

I realized dgrid has a get function which i can use to access the datasource attributes. So formatter was not needed instead get was used. Under is my solution :
Javascript
},
addressType:{
label:"Address Type",
get: function(object){
if(object.postalAddress == true){
return 'Postal';
}else{
return 'Business';
}
}
}
