将日期时间字符串传递给 laravel 模型工厂选择随机日期

Question

我有一个 table 个错误，一个 table 个操作和一个历史记录 table。

每次对错误执行操作时，我都想将其记录在我的历史记录中 table。

我正在尝试将一些虚拟数据植入数据库。这就是我正在做的：

public function run()
{
    $bugs = App\Bug::all();

    foreach ($bugs as $bug) {

        //Add a history entry for the bug
        factory(App\History::class)->create([
            'action_id' => App\Action::where('name', '=', 'create')->first()->id,
            'user_id' => $bug->project->users->random()->id,
            'bug_id' => $bug->id,
            'created_at' => $bug->created_at,
            'updated_at' => $bug->updated_at
        ]);

        //Here I perform some random actions and save the history of the action
        for ($i = 0; $i < 9; $i ++) {

            $createdDate = $bug->created_at->addDays(mt_rand(1,6))->addHours(mt_rand(1,23))->toDateTimeString();

            //This is the only action I'm having trouble with
            factory(App\History::class, 1)->create([
                        'created_at' => $createdDate,
                        'action_id' => App\Action::where('name', '=', 'comment')->first()->id,
                    ])->each(function ($history) {
                        $history->comment()
                            ->save(factory(App\Comment::class)->make());
                    });



        }
    }
}

在我的虫子模型工厂里我有

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

return [
    'name' => $faker->word,
    'description' => $faker->sentence,
    'project_id' => $faker->randomNumber(),
    'created_at' => $faker->dateTimeBetween('-1 years'),
];
});

我希望上面的 created_at 字段比 bug 的 created_at 字段晚 1-5 天和 1-23 小时存储一个历史条目。

我现在看到的是过去一年内的随机事件。好像我在做这个

$faker->dateTimeBetween('-1 years')

所以有时我的历史记录 table 是创建条目之前的条目。

我已经在日期中进行了硬编码并且它正确地存储了它。

与有关。由于 PHP 5+

"objects are passed by references by default"

通过克隆它们，您将获得一个新的不同实例。因此，这应该适合您：

$createdDate = $bug->created_at->copy()->addDays(mt_rand(1,6))->addHours(mt_rand(1,23))->toDateTimeString();
