Laravel 5.7.10 Released


October 24th, 2018

The Laravel team shipped Laravel 5.7.10 yesterday with a handful of new features, fixes, and changes:

loadCount Eloquent Collection Method

First up, is the ability to load relationship counts on an Eloquent collection. Before this feature, you could only load relationships, but now you can call loadCount() to get counts for all relations.

The pull request illustrates how you could use loadCount() with the following example:

$events = Event::latest()->with('eventable')->paginate();

$groups = $events->map(function ($event) {
    return $event->eventable;
})->groupBy(function ($eventable) {
    return get_class($eventable);


return new EventIndexResponse($events);

Now all the eventable models would have a count value for comments or hearts respectively. The loadCount feature was added by Tim MacDonald. Tim is the author of the Laravel Log Fake package that we featured earlier this month. Nice work Tim!

Pass a Model to assertSoftDeleted

You can use the assertSoftDeleted to assert that a model has been soft deleted. Before Laravel 5.7.10, the method call might look something like the following:

$this->assertSoftDeleted('users', [
    'id' => $user->id,
    'name' => $user->name,
    'email' => $deletedUser->email,

Now, thanks to an update to the assertSoftDeleted method, you can pass the model directly which will assert against the table’s primary key and primary key value:


// Same as:
$this->assertSoftDeleted('users', ['id' => $user->id]);

Thanks to Dwight Watson for this nice shortcut!

Add Mock and Spy Objects to the Container

Titas Gailius added the ability to more conveniently add mock and spy instances to the container in a test:

$this->mock(Mailer::class, function ($mock) {

$this->spy(Dispatcher::class, function ($mock) {

These methods are syntactic sugar for something like the following:

$this->instance(Mailer::class, Mockery::mock(Mailer::class, function ($mock) {

UUID Validation

André Filipe contributed a UUID validation method which uses a regex to avoid dependency of ramsey/uuid in the illuminate/validation component.

The name of the validation rule is uuid:

    'post' => 'required|uuid'

Notification Fake can Assert a Preferred Locale

Derek MacDonald added the ability to assert the preferred notification fake locale on notifications that implement the HasLocalePreference interface:


$user = factory(User::class)->create(['locale' => 'au']);

// Call an artisan console command that invokes:
Notification::send($user, new AFLTrade('Chad Wingard', 'Hawthorn'));

Notification::assertSentTo($user, AFLTrade::class, function ($notification, $channels, $notifiable, $locale) use ($user) {
    return $notification->player === 'Chad Wingard' &&
        $notification->club === 'Hawthorn' &&
        $notifiable === $user &&
        $locale === 'au';
