Yajra Datatables changes datetimes incorrectly when using Laravel's Carbon and Javascript's Moment.js libraries.

Yajra Datatables changes datetimes incorrectly when using Laravel's Carbon and Javascript's Moment.js libraries.

When using Yajra Datatables with Laravel, Carbon, and Moment.js libraries, you might encounter an issue where datetime values are displayed incorrectly in the Datatables interface. This issue can occur due to the differences in how these libraries handle datetime formatting.

To understand the problem, let's first look at how these libraries work:

1. Laravel's Carbon: Carbon is a PHP library used for working with dates and date intervals in Laravel. It provides a fluent interface for manipulating dates and time.

2. Yajra Datatables: Yajra Datatables is a Laravel package that makes it easy to work with Datatables in Laravel. It abstracts the process of fetching data from Laravel and returning it to Datatables.

3. Moment.js: Moment.js is a JavaScript library used for manipulating dates and time in the browser. It provides a fluent interface for working with dates and time in JavaScript.

The issue arises when we try to display datetime values in the Datatables interface using both Carbon and Moment.js. Here's what happens:

1. Laravel's Carbon converts datetime values to a specific format (usually 'Y-m-d H:i:s') when returning data to the controller.

2. Yajra Datatables uses this datetime value to build the DataTables record.

3. When the DataTables record is rendered in the browser, Moment.js is used to parse and display the datetime value.

4. Moment.js might not parse the datetime value correctly if it's in a different format than what Moment.js expects.

To solve this issue, we need to ensure that the datetime values are in the correct format when they're passed to Moment.js. Here are some steps you can follow to achieve this:

1. In your Laravel controller, convert the datetime values to a Moment.js-friendly format using Moment.js's 'parse' method before returning the data to Yajra Datatables.

use Carbon\Carbon;
use Yajra\DataTables\Facades\DataTables;

public function getData()
{
    $query = MyModel::query();

    return DataTables::of($query)
        ->addColumn('created_at', function ($model) {
            return (new Carbon($model->created_at))->format('YYYY-MM-DD HH:mm:ss');
        })
        ->make(true);
}

2. In your JavaScript code, use Moment.js's 'format' method to display the datetime value in the desired format in the DataTables interface.

$('#dataTable').DataTable({
    processing: true,
    serverSide: true,
    ajax: '/api/data',
    columns: [
        { data: 'created_at', name: 'created_at' },
        // other columns
    ],
    columnDefs: [
        {
            targets: 0,
            render: function (data, type, row) {
                return moment(data).format('YYYY-MM-DD HH:mm:ss');
            }
        },
        // other column definitions
    ]
});

By following these steps, you should be able to display datetime values correctly in the Yajra Datatables interface when using Laravel's Carbon and Moment.js libraries.
