Is it possible to prevent Laravel running Model Events when the database is being Seeded?

Question

Laravel's seeder runs a variety of Model Events on my models which trigger New Order notification emails, among other things, from the Product::saved() Model Event.

This significantly slows down database seeding. Is it possible to detect whether a Seed is being ran and if so, tell Laravel not to run the Model Events?

There are functions on the Model class which will allow you to ignore events.

Before using a model to seed, you will need to do something like this...

YourModel::flushEventListeners();

This seems not to work with custom events. The other solution: ``` // Remove Dispatcher Model::unsetEventDispatcher() ``` Seems to work in that case. – Bart Ducheyne May 30 '17 at 15:14
This worked (laravel 8). I placed this in the top of seeder->run – Md. A. Apu Aug 17 '21 at 12:16

I recommend to remove the Dispatcher in this Case from the Eloquent Model.

For example.

// Check Dispatcher
Model::getEventDispatcher()

// Remove Dispatcher
Model::unsetEventDispatcher()

// Add Dispatcher
Model::setEventDispatcher(new \Illuminate\Events\Dispatcher);

Add WithoutModelEvents Trait to your seeder

namespace Database\Seeders;

use Illuminate\Database\Console\Seeds\WithoutModelEvents;
use Illuminate\Database\Seeder;

class DatabaseSeeder extends Seeder
{
    use WithoutModelEvents;

    public function run(): void
    {
        // Silent eloquent queries ...
    }
}

This is the correct and modern way to do this. Thanks! – Jack Oct 27 '22 at 19:18
