Laravel - Queues - Class Structure

Job classes are very simple, normally containing only a handle method that is invoked when the job is processed by the queue. To get started, let's take a look at an example job class. In this example, we'll pretend we manage a podcast publishing service and need to process the uploaded podcast files before they are published:

    
    podcast = $podcast;
        }
    
        /**
         * Execute the job.
         *
         * @param  App\Services\AudioProcessor  $processor
         * @return void
         */
        public function handle(AudioProcessor $processor)
        {
            // Process uploaded podcast...
        }
    }
	

In this example, note that we were able to pass an Eloquent model directly into the queued job's constructor. Because of the SerializesModels trait that the job is using, Eloquent models and their loaded relationships will be gracefully serialized and unserialized when the job is processing.

If your queued job accepts an Eloquent model in its constructor, only the identifier for the model will be serialized onto the queue. When the job is actually handled, the queue system will automatically re-retrieve the full model instance and its loaded relationships from the database. This approach to model serialization allows for much smaller job payloads to be sent to your queue driver.
