如何/可以有选择地将数字传递给Laravel工厂,以便如果我不提供数字,它会执行默认的操作,并且如果我使用它们,会使用数字吗?
例如,我有一个Student
模型。它会产生一个随机的男性或女性学生,并有50%的机会使用Faker
来产生中间名。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;
});
我已经看到我可以使用State作为传递var的方法。例如,我可以做这样的事情:
$student = factory(App\Student::class)->state('male')->make();
这将调用我的工厂的这一位,因此将first_name
,middle_name
和gender
属性修改为与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,上面的代码创建的学生年龄在4到18岁之间。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,使一个8到9之间的学生:
$birth_date = $faker->dateTimeBetween($startDate = '-9 years', $endDate = '-9 years', $timezone = null);
$student = faker(App\Student::class)->make(['birth_date' => $birth_date]);
但是我宁愿做这样的事情:
$student = faker(App\Student::class)->make($minAge = 8, $maxAge = 9);
这可能吗?
答案 0 :(得分:0)
您可以在学生模型工厂中定义min_age
和max_age
并使用以下代码:
$student = faker(App\Student::class)->make(['min_age' => 8, 'max_age' => 9]);
