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!

<?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'];

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

        public function created(DatabaseNotification $notification): void

<?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
