Laravel 8模型工厂使用rand

Question

我刚刚更新了我的Laravel安装从7到8，我正试图将我的旧工厂转换为新的基于类的工厂。

我有以下Laravel 7工厂;

$bottles = factory(Bottle::class, rand(1, 5))->create([
'email' => $faker->safeEmail
])

我如何将其转换为Laravel 8。rand部分似乎不起作用，我试过了;

$bottles = Bottle::factory()->rand(1, 5)->create([
'email' => $this->faker->safeEmail
]);

但我得到以下错误;

Call to undefined method DatabaseFactoriesBottleFactory::rand()

Answer 1

您可以为laravel8工厂使用count()方法:

$bottles = Bottle::factory()->count(rand(1, 5))->create([
'email' => $this->faker->safeEmail
]);
