Each project doesn't always expect the same set of default and you might have a requirement to customise Laravel Nova default behavior. For example setting default datetime format for DateTime field.
Imagine you have the following scenario:
use Laravel\Nova\Fields\DateTime;
DateTime::make('Created At')->sortable()->format('D-M-yyyy H:m'),
DateTime::make('Updated At')->sortable()->format('D-M-yyyy H:m'),
Instead of writing ->sortable()->format('D-M-yyyy H:m') for each field you can override the field by adding App\Nova\Fields\DateTime and add the following code:
<?php
namespace App\Nova\Fields;
class DateTime extends \Laravel\Nova\Fields\DateTime
{
/**
* Create a new field.
*
* @param string $name
* @param string|null $attribute
* @param mixed|null $resolveCallback
* @return void
*/
public function __construct($name, $attribute = null, $resolveCallback = null)
{
parent::__construct($name, $attribute, $resolveCallback);
$this->sortable()->format('D-M-yyyy H:m');
}
}
And your fields can be simplify to:
use App\Nova\Fields\DateTime;
DateTime::make('Created At'),
DateTime::make('Updated At'),
