laravel factory

11. Create a factory:
2	php artisan make:factory ItemFactory --model=Item
3      
4Import Illuminate\Database\Eloquent\Factories\HasFactory trait to your model:
5
6use Illuminate\Database\Eloquent\Factories\HasFactory;
7use Illuminate\Database\Eloquent\Model;
8
9class Item extends Model
10{
11    use HasFactory;
12
13    // ...
14}
15
162. Use it like this:
17	
18	$item = Item::factory()->make(); // Create a single App\Models\Item instance
19
20	// or
21
22	$items = Item::factory()->count(3)->make(); // Create three App\Models\Item instances
23
243. Use create method to persist them to the database:
25
26  $item = Item::factory()->create(); // Create a single App\Models\Item instance and persist to the database
27
28  // or
29
30  $items = Item::factory()->count(3)->create(); // Create three App\Models\Item instances and persist to the database
31

1factory(App\User::class, 30)->create()->each(function($user) {
2
3    $entity = factory(App\Entity::class)->make();
4
5    $address = factory(App\Address::class)->create([
6        'entity_id' => $entity
7    ]);
8
9    $user->entities()->save($entity);
10});
