Tappable Scopes in Laravel

The Problem

Laravel's model scopes don't work with Scout (search).
Reusing scopes across models means copying code OR using traits (but Scout still breaks).
Leads to duplicate query logic.

The Solution: Tappable Scopes

Instead of defining scopes inside models, create scope classes that can be used in both Eloquent & Scout queries!

Atomic Types (Built-in and Scalar)

// Built-in types
$variable = null;             // null type

// Scalar types
$boolVar = true;              // bool type
$intVar = 42;                 // int type
$floatVar = 3.14;             // float type

Task Completed: Replaced All Enums with Pascal Case from SNAKE_CASE

Steps

Copy both files to the appropriate namespace.

Register the Rector rule:

->withRules([
    RenameEnumCasesToPascalCaseRector::class,

])

Put this into event service providor's boot method

public function boot(): void
{
    // Observe the DatabaseNotification model for created events
    DatabaseNotification::observe(new class {
        
        // Listen to the created event 
        public function created(DatabaseNotification $notification): void

HasLabel.php Trait

namespace App\Concerns\Enums;
 
trait HasLabel
{
    public function label(): string
    {
        return str($this->name)

	<?php
	Artisan::command('generate-tests', function () {
	// Define the base path where class files are located
	$files = File::allFiles(base_path('app/Classes'));

	foreach ($files as $file) {
	// Get the relative path of the current class file and apply string manipulations
	$path = str($file->getRelativePathname())
	->replace('.php', '') // Remove the .php extension
	->replace('/', '\\') // Replace directory slashes with namespace slashes

	<?php

	// In Laravel, we have the $with property to automatically load a relationship every time.
	// However, selecting a specific column by default for every model query doesn't seem possible...
	// but here's a hack I found!

	class Post extends Model
	{
	// To automatically load the 'author' relationship on every query
	protected $with = ['author'];

	<?php

	use App\Enums\PostStatus;
	use Illuminate\Database\Eloquent\Model;
	use Illuminate\Database\Eloquent\Attributes\Attribute;

	class Post extends Model
	{

	// We can easily cast the 'status' column to an enum instance
