Model Observers

Laravel Tip: Use Model Observers to Keep Controllers Clean

Ever find yourself sprinkling the same “after save” or “before delete” logic in multiple controllers?

Laravel Observers let you move that into a single, reusable place.

Before (Logic Scattered Everywhere)

// In Controller
$user = User::create($data);
Mail::to($user->email)->send(new WelcomeMail($user));

After (With Observer)

Create an Observer

php artisan make:observer UserObserver --model=User

Add Your Logic

class UserObserver
{
    public function created(User $user)
    {
        Mail::to($user->email)->send(new WelcomeMail($user));
    }
}

Register It (in AppServiceProvider)

use App\Models\User;
use App\Observers\UserObserver;
public function boot()
{
    User::observe(UserObserver::class);
}

Now every time a user is created (no matter from where), the welcome email fires automatically.

Why It’s Awesome

• Keeps controllers lightweight
• Avoids duplicating logic
• Centralizes “model lifecycle” actions
