Answer 1

Call the model Object then call unsetEventDispatcher after that you can do whatever you want without worrying about Event triggering

like this one:

    $IncidentModel = new Incident;
    $IncidentModel->unsetEventDispatcher();

    $incident = $IncidentModel->create($data);

In laravel 8.x :

Saving A Single Model Without Events

Sometimes you may wish to "save" a given model without raising any events. You may accomplish this using the saveQuietly method:

$user = User::findOrFail(1);

$user->name = 'Victoria Faith';

$user->saveQuietly();

See Laravel docs

Solution for Laravel 8.x

With Laravel 8 it became even easier, just use saveQuietly method:

$user = User::find(1);
$user->name = 'John';

$user->saveQuietly();

Solution for Laravel 7.x and 8.x

On Laravel 7 (or 8) wrap your code that throws events as per below:

$user = User::withoutEvents(function () use () {
    $user = User::find(1);
    $user->name = 'John';
    $user->save();

    return $user;
});

Solution for Laravel versions from 5.7 to 6.x

The following solution works from the Laravel version 5.7 to 6.x, for older versions check the second part of the answer.

In your model add the following function:

public function saveWithoutEvents(array $options=[])
{
    return static::withoutEvents(function() use ($options) {
        return $this->save($options);
    });
}

Then to save without events proceed as follow:

$user = User::find(1);
$user->name = 'John';

$user->saveWithoutEvents();

For more info check the Laravel 6.x documentation

Solution for Laravel 5.6 and older versions.

In Laravel 5.6 (and previous versions) you can disable and enable again the event observer:

// getting the dispatcher instance (needed to enable again the event observer later on)
$dispatcher = YourModel::getEventDispatcher();

// disabling the events
YourModel::unsetEventDispatcher();

// perform the operation you want
$yourInstance->save();

// enabling the event dispatcher
YourModel::setEventDispatcher($dispatcher);

For more info check the Laravel 5.6 documentation

Answer 4

You shouldnt be mixing session flashing with model events - it is not the responsibility of the model to notify the session when something happens.

It would be better for your controller to call the session flash when it saves the model.

This way you have control over when to actually display the message - thus fixing your problem.

Answer 5

In laravel 7.x you can do that as easy as

use App\User;

$user = User::withoutEvents(function () use () {
    User::findOrFail(1)->delete();

    return User::find(2);
});

See more in Laravel 7.x Muting Events documentation

Answer 6

There is a nice solution, from Taylor's Twitter page:

Add this method to your base model, or if you don't have one, create a trait, or add it to your current model

public function saveQuietly(array $options = [])
{
    return static::withoutEvents(function () use ($options) {
        return $this->save($options);
    });
}

Then in you code, whenever you need to save your model without events get fired, just use this:

$model->foo = 'foo';
$model->bar = 'bar';

$model->saveQuietly();

Very elegant and simple :)
