# Keeping track of workflows

# Persistance

All workflows and their individual steps get stored inside the database. When you start a workflow, an instance of the workflow will be returned.

$workflow = PublishPodcastWorkflow::start($podcast);

Note

A workflow is just a regular Eloquent model, so you can do all the things with it that you're used to from Eloquent.

By default, these tables are called workflows and workflow_jobs. This can be changed in the configuration, however.

# Performing an action after the workflow has finished

Similar to how batches work in Laravel(opens new window) , you can register a callback to execute after the workflow has finished. To do so, call the then method on the WorkflowDefinition and pass in a closure.

public function definition(): WorkflowDefinition
{
    return Workflow::define('Example Workflow')
        ->addJob(new ExampleJob())
        ->then(function (Workflow $workflow) {
            // This will get called once every job in the workflow has finished.
            // It gets passed the workflow instance.
        });
}

Alternatively, you can pass an invokable class to the then callback.

class SendNotification
{
    public function __invokable(Workflow $workflow)
    {
        // Do something with the workflow...
    }
}

Workflow::define('Example Workflow')
    ->addJob(new ExampleJob())
    ->then(new SendNotification());

# Inspecting workflows

A workflow instance exposes several methods to inspect its current state.

// The date the workflow finished...
$workflow->finished_at;

// The date the workflow was cancelled...
$workflow->cancelled_at;

// A collection of WorkflowJob instances that have not been processed yet...
$workflow->pendingJobs();

// A collection of WorkflowJob instances that have failed...
$workflow->failedJobs();

// Indicates if the workflow has finished...
$workflow->isFinished();

// Indicates if the workflow has been cancelled...
$workflow->isCancelled();
