Let’s get started.

Laravel Installation

Open terminal and run this command to create a laravel project.

composer create-project laravel/laravel myblog

To start the development server of laravel –

php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

What are Model Events in Laravel?

A Model in Laravel 10 provides an abstraction for working with a database table via a high-level API. Among these APIs are events, which are fired when actions are performed on the model.

Model events are simply life cycle hooks that you may use to easily run code when database records are saved, changed, or removed.

Events receive the model instance that is being saved, modified, or removed.

Here are the following events which we can use with laravel model –

• creating and created: Fires before and after records have been created.
• updating and updated: Fires before and after records are updated.
• saving and saved: Fires before and after records are saved (i.e created or updated).
• deleting and deleted: Fires before and after records are deleted or soft-deleted.
• restoring and restored: Fires before and after soft-deleted records are restored.
• retrieved: Fires after records have been retrieved.

Laravel Model Create Events

Here, you will understand the complete concept of model create events with an example.

Model create events means the events which fired when you create an instance of any Model and perform create operation (to save data).

Let’s consider an example.

Step #1: Create a Model (Say Post)

Open project terminal and run this command to create a Post model,

php artisan make:model Post

It will create a model class file of name Post.php inside /app/Models folder.

Step #2: Register Model Create Events

Open Post.php and write this code into it.

<?php
  
namespace App;
  
use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Str;
  
class Post extends Model
{
    /**
     * The attributes that are mass assignable.
     *
     * @var array<int, string>
     */
    protected $fillable = [
        'title', 
        'content', 
        'slug'
    ];
    
    // Model create events
    protected static function boot()
    {
        parent::boot();
   
        static::creating(function ($post) {
            info('Creating event call: '.$post);
   
            $post->slug = Str::slug($post->title);
        });
  
        static::created(function ($post) {
        	info('Created event call: '.$post);
        });
    }
}

Here, when a new Post model is being created. The creating event is triggered, and you can see we used a closure to generate a slug based on the title attribute.

For slug, we are using Str::slug method of Laravel to create a URL-friendly slug from the title.

Step #3: Create Post data via Model

Next, when you create a new Post instance and save data via it, the creating event will automatically set the slug for you.

Here’s how you can create a new post:

<?php
     
namespace App\Http\Controllers;
    
use Illuminate\Http\Request;
use App\Models\Post;
    
class PostController extends Controller
{
    public function index(Request $request)
    {
        $post = Post::create([
            "title" => "This is Testing",
            "content" => "This is a Testing"
        ]);
  
        dd($post);
    }
}

Now, Once you run following code and you will find following log for calling creating event and created event as:

Output

[2023-10-27 14:37:26] local.INFO: Creating event call: {"title":"This is Testing","content":"This is a Testing"}

[2023-10-27 14:37:26] local.INFO: Created event call: {"title":"This is Testing","content":"This is a Testing","slug":"this-is testing","updated_at":"2023-10-27T14:37:26.000000Z","created_at":"2023-10-27T14:37:26.000000Z","id":10}

That’s it.
