如何将变量传递给 Laravel 中的工厂？

Question

我如何 do/can 我有选择地将数字传递给 Laravel 工厂，这样如果我不提供数字，它会执行默认操作，如果我提供，它会使用它们？

例如我有一个 Student 模型。它生成一个随机的男性或女性学生，有 50% 的机会使用 Faker 的中间名，如预期的那样。它看起来像这样：

$factory->define(App\Student::class, function (Faker $faker) {

    $gender = $faker->randomElement($array = array ('m','f'));
    $has_middle_name = $faker->boolean($chanceOfGettingTrue = 50);
    $student = [];

    if ($gender == 'm') {
        $student['first_name'] = $faker->firstNameMale;
        if ($has_middle_name) {
            $student['middle_name'] = $faker->middleNameMale;
        }
    } else {
        $student['first_name'] = $faker->firstNameFemale;
        if ($has_middle_name) {
            $student['middle_name'] = $faker->firstNameMale;
        }       
    }

    $student['last_name'] = $faker->lastName;
    $student['gender'] = $gender;

    $student['birth_date'] = $faker->dateTimeBetween($startDate = '-18 years', $endDate = '-4 years', $timezone = null);

    return $student;

});

我看到我可以使用 State 作为传递变量的方法。例如我可以这样做：

$student = factory(App\Student::class)->state('male')->make();

这将调用我工厂的这一点，因此修改 first_name、middle_name 和 gender 属性以与 male:

一致

$factory->state(App\Student::class, 'male', function (Faker $faker) {

    $student = [];
    $student['first_name'] = $faker->firstNameMale;
    $has_middle_name = $faker->boolean($chanceOfGettingTrue = 50);
    if ($has_middle_name) {
        $student['middle_name'] = $faker->middleNameMale;
    }    
    $student['gender'] = 'm';

    return $student;

});

但是，我上面的代码创建了一个年龄在 4 到 18 岁之间的学生。如果我想创建一个特定年龄的学生怎么办？我知道我可以这样做来培养 8 到 9 岁的学生：

$birth_date = $faker->dateTimeBetween($startDate = '-9 years', $endDate = '-9 years', $timezone = null);
$student = faker(App\Student::class)->make(['birth_date' => $birth_date]);

但我宁愿这样做：

$student = faker(App\Student::class)->make($minAge = 8, $maxAge = 9);

这可能吗？？

Answer 1

您可以将 min_age 和 max_age 定义到您的 Student 模型工厂并使用以下代码：

$student = faker(App\Student::class)->make(['min_age' => 8, 'max_age' => 9]);
