Declaring and using ModelNotFoundException

Hi All,

I'm following along with the Laravel from scratch tutorials and finding it extremely useful. Challenging at times as I am new to a lot of the languages and tools used (php, laravel, composer, artisan etc). I have installed laravel 9 with php 8.2 on apache 2.4 on an AWS ubuntu AMI. Everything has been working fantastically so far but there has been the odd one or two things that I have had to work my way through doing some reading on. But I have come across an issue that I dont seem to be able to get past.

In Section 3 -> Blade -> "A few tweaks and considerations" jeffrey uses a class called 'ModelNotFoundException" When i try to call this class I get an error -> Class "App\Models\ModelNotFoundException" not found

I am calling the class from a script in app/models called Post.php.

I have added a use statement at the top of that script

use Illuminate\Database\Eloquent\ModelNotFoundException;

I am using two other classes within the same block of code (learned through the tutorial) which work fine.

The File:files class and method and the YamlFrontMatter::parsefiles class and method. Both have been referenced with a similar use statement at the beginning of the code.

use Spatie\YamlFrontMatter\YamlFrontMatter;

I have also tried using this ModelNotFoundException class in my web.php routes file and it works fine when I put the use Illuminate\Database\Eloquent\ModelNotFoundException; statement at the top of that file.

<?php

namespace App\Models;
use Illuminate\Support\Facades\File;
use Spatie\YamlFrontMatter\YamlFrontMatter;
use Illuminate\Database\Eloquent\ModelNotFoundException;


class Post {

    public $title;
    public $excerpt;
    public $date;
    public $body;
    public $slug;

    public function __construct($title, $excerpt, $date, $body, $slug)
    {
        $this->title = $title;
        $this->excerpt = $excerpt;
        $this->date = $date;
        $this->body = $body;
        $this->slug = $slug;
    }

    public static function all()
    {
        throw new ModelNotFoundExecption();
        return cache()->rememberForever('posts.all', function (){
           return collect(File::files(resource_path("posts")))
                ->map(fn($file) => YamlFrontMatter::parsefile($file))
                ->map(fn($document) => new Post(
                    $document->title,
                    $document->excerpt,
                    $document->date,
                    $document->body(),
                    $document->slug
                ))
                ->sortByDesc('date');
        });
    }

    public static function find($slug)
    {
        
        $post = static::all()->firstWhere('slug', $slug);
        return $post;
        // if (! $post) {
        //     throw new ModelNotFoundExecption();
        // }
        
    }
}

Any help would be gratefully received I am assuming it has something to do with the namespace as the error is suggesting that App\Models\ModelNotFoundException cannot be found. But of course thats the class namespace I am already in.
