我有以下代码,但是当我运行我的工厂时出现以下异常:
Cannot redeclare questionIndex() (previously declared in /Users/user/Desktop/my-app/database/factories/QuestionFactory.php:42) in /Users/user/Desktop/my-app/database/factories/QuestionFactory.php on line 46
当我运行我的单元测试时会发生这种情况,而这个特定的工厂现在不在测试中。我有其他工厂有一个生成器,但函数的名称完全不同。称为 autoIncrement()
。
<?php
use Faker\Generator as Faker;
/*
|--------------------------------------------------------------------------
| Model Factories
|--------------------------------------------------------------------------
|
| This directory should contain each of the model factory definitions for
| your application. Factories provide a convenient way to generate new
| model instances for testing / seeding your application's database.
|
*/
$questionIndex = questionIndex();
$factory->define(App\Models\Question::class, function (Faker $faker, $overrides) use ($questionIndex) {
$question = [
'How is 2 + 2?',
'Choose, what is the possibility to win the lottery?',
'According to the Big Brother, is 2 + 2 = 5?'
];
$questionType = [
'numeric',
'multiple-choice',
'true-or-false'
];
$index = $questionIndex->current();
$questionIndex->next();
return [
'title' => $question[$index],
'type' => $questionType[$index],
'category_id' => $overrides['category_id']
];
});
function questionIndex() {
for ($i = 0; $i < 100000; $i++) {
yield $i%3;
}
}
最佳答案
尝试使用函数声明屏蔽/保护以防文件被包含两次,然后函数将不会被重新声明。
if (!function_exists('questionIndex')) {
function questionIndex() {
for ($i = 0; $i < 100000; $i++) {
yield $i%3;
}
}
}
