Question

我已经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);
    }
}

然后我将其触发1128个项目（两次）并观察到结果：

默认情况下，批次按200个项目分组，从我看到的内容来看，同时有3个作业同时生成。不幸的是，无法知道将首先处理哪个作业，因此，每次批处理都会在日志中显示模型，如输出所示：621525, 412186, 621282用于首次调用操作，621282, 621525, 412186用于调用操作第二次（模型以相同的方式在作业之间拆分，但是处理的作业顺序发生了变化）。这里的问题是，如果我将视图保存到CSV文件中，则顺序很重要。

我希望在给定的时间仅执行一项工作即可执行给定的操作，这可以解决我的问题。这可能吗？

将地平线用作队列工作器

Answer 1

完成此操作的方法是更改地平线配置中的processes值：

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

Nova排队操作触发多个作业
