For some reason, I'm unable to generate a failed jobs table in Lumen 5.2.
I've consulted:
The Lumen 5.2 Docs
The Lumen 5.1 Docs
The Laravel 5.2 Docs
And the only one mentioned generator artisan queue:failed-table
simply returns:
[Symfony\Component\Console\Exception\CommandNotFoundException]
Command "queue:failed-table" is not defined.
Did you mean one of these?
queue:failed
queue:forget
queue:flush
queue:retry
queue:work
queue:listen
queue:restart
Does anyone have a clue why this may be? The application itself is casting errors due to (well, errors) and not having a failed jobs table to process.
Much obliged!
Laravel queues provide a unified API across a variety of different queue backends, such as Beanstalk, Amazon SQS, Redis, or even a relational database. Queues allow you to defer the processing of a time consuming task, such as sending an email, until a later time.
Dispatcher is a Laravel artisan command scheduling tool used to schedule artisan commands within your project so you don't need to touch the crontab. This sounds brilliant for shared hosts and on-premise apps.
Remember, queue workers, are long-lived processes and store the booted application state in memory. As a result, they will not notice changes in your code base after they have been started. So, during your deployment process, be sure to restart your queue workers.
Laravel queues provide a unified queueing API across a variety of different queue backends, such as Amazon SQS, Redis, or even a relational database. Laravel's queue configuration options are stored in your application's config/queue.phpconfiguration file.
Dispatching To A Particular Queue By pushing jobs to different queues, you may "categorize" your queued jobs and even prioritize how many workers you assign to various queues. Keep in mind, this does not push jobs to different queue "connections" as defined by your queue configuration file, but only to specific queues within a single connection.
The first concept is a work queue. A queue is simply a list of items where you put items into the queue and remove them in the same order (First In/First Out or FIFO). Work queues provide a central location for us to store the units of work we want to be done. The second concept is a job.
I believe that CmdrSharp is correct that Lumen does not include the artisan queue:failed-table
command.
In case it's helpful, here are the steps that I took to create a failed_jobs table myself:
1) Create a migration for creating the failed_jobs table. The generated migration will be placed in the /database/migrations folder.
php artisan make:migration create_failed_jobs_table --table=failed_jobs
2) Edit the migration so that it looks like this:
<?php
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateFailedJobsTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('failed_jobs', function (Blueprint $table) {
$table->increments('id');
$table->text('connection');
$table->text('queue');
$table->longText('payload');
$table->timestamp('failed_at')->useCurrent();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::drop('failed_jobs');
}
}
3) Run the migration to create the table
php artisan migrate
Good luck!
