在Laravel中播种数据库时使用进度条

Question

我必须将相当多的数据存入数据库,我希望能够在发生这种情况时向用户显示进度条.我知道这是记录在案的:

• https://laravel.com/docs/master/artisan#registering-commands(上面)
• http://symfony.com/doc/2.7/components/console/helpers/progressbar.html

但我在播种机中遇到问题.

<?php

use Illuminate\Database\Seeder;

class SubDivisionRangeSeeder extends Seeder
{
    public function run()
    {
        $this->output->createProgressBar(10);
        for ($i = 0; $i < 10; $i++) {
            sleep(1);
            $this->output->advance();
        }
        $this->output->finish();
    }
}

要么

<?php

use Illuminate\Database\Seeder;

class SubDivisionRangeSeeder extends Seeder
{
    public function run()
    {
        $this->output->progressStart(10);
        for ($i = 0; $i < 10; $i++) {
            sleep(1);
            $this->output->progressAdvance();
        }
        $this->output->progressFinish();
    }
}

有任何想法吗？

您可以通过访问输出 $this->command->getOutput()

public function run()
{
    $this->command->getOutput()->progressStart(10);
    for ($i = 0; $i < 10; $i++) {
        sleep(1);
        $this->command->getOutput()->progressAdvance();
    }
    $this->command->getOutput()->progressFinish();
}
