Laravel. Disable observer methods if the database is seeding

Question

I have an observer for my User model. Inside my observer->created event i have some code.

public function created(User $user)
{
    sendEmail();
}

So, the idea is, when a user is created, the system will send for the user email notification that the account was created.

Question: When the database is seeding, it also calls this method 'created' and sends users (that are in the seeds) email notification. So, my question is, how can i check, probably inside this 'created' method if at the moment laravel is seeding data -> do not send email of do not run the 'created' observer method.

Tried to google, found something, but not working correct. Something like YourModel::flushEventListeners();

Answer 1

You can use YourModel::unsetEventDispatcher(); to remove the event listeners for a model temporary.

If you need them after seeding in the same execution, you can read the dispatchers, unset them and then set them again.

$dispatcher = YourModel::getEventDispatcher()
// Remove Dispatcher 
YourModel::unsetEventDispatcher();

// do stuff here

// Re-add Dispatcher
YourModel::setEventDispatcher($dispatcher);

 namespace Database\Seeders; 
                                                    
    use App\Models\Blog; 
    use Illuminate\Database\Seeder;

    class BlogsTableSeeder extends Seeder
    {
         public function run()
         {
   
           Blog::withoutEvents(function ()  {
                
            // normally
                 Blog::factory()
                 ->times(10)      
                 ->hasUploads(1)        //hasOne
                 ->hasComments(2)       //hasMany                           
                 ->create();

            });


         }
    }

You may mute event with WithoutModelEvents trait

use Illuminate\Database\Console\Seeds\WithoutModelEvents;

class SomeSeeder extends Seeder
{
    use WithoutModelEvents;
    
    public function run()
    {
        User::factory( 30 )->create();
    }
}

or you may try createQuietly method of a factory, for example

class SomeSeeder extends Seeder
{
    public function run()
    {
        User::factory( 30 )->createQuietly();
    }
}

You could use the saveQuietly() function https://laravel.com/docs/8.x/eloquent#saving-a-single-model-without-events This allows you to disable all events for a single model.
