Nova 队列操作触发多个作业

Question

我创建了这样一个动作：

use Illuminate\Bus\Queueable;
use Laravel\Nova\Actions\Action;
use Illuminate\Support\Collection;
use Laravel\Nova\Fields\ActionFields;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
use Laravel\Nova\Fields\BelongsTo;
use Illuminate\Support\Facades\Queue;

class ExportToCsv extends Action implements ShouldQueue
{
    use InteractsWithQueue, Queueable;

    public function handle(ActionFields $fields, Collection $models)
    {
        var_dump(time(), collect($models)->map(function($item){
            return $item->id;
        })->first());

        sleep(3);
    }
}

然后我为 1128 个项目触发它（两次）并观察结果：

默认情况下，批次按 200 个项目分组，据我所见，同时生成了 3 个作业。不幸的是，无法知道将首先处理哪个作业，因此每个批次更改的模型都会显示在日志中，如输出所示：621525, 412186, 621282 表示第一次调用操作时，621282, 621525, 412186 表示调用操作时第二次（模型以相同的方式在作业之间拆分，但作业处理的顺序发生了变化）。这里的问题是，如果我将视图保存到 CSV 文件，顺序很重要。

我希望在给定时间针对给定操作只产生一个作业，这将解决我的问题。这可能吗？

使用 horizon 作为队列工作者

Answer 1

完成此操作的方法是更改 horizon 配置中的 processes 值：

    'environments' => [
        'local' => [
            'supervisor-1' => [
                'connection' => 'redis',
                'queue' => ['default'],
                'balance' => 'simple',
                'processes' => 1,
                'tries' => 3,
            ],
        ],
