Showing transition as graph

[shahonseven]

Hi, I needed to see possible transition for easier debugging, so here's how I did it

$states = MyModel::getStatesFor('status');

$graph = new \Graphviz\Digraph();

foreach ($states as $fromState) {
  $myModel->status = $fromState;
  $transitionableStates = $myModel->status->transitionableStates();

  foreach($transitionableStates ?? [] as $toState) {
    $graph->edge([$fromState, $toState]);
  }
}

echo $graph->render();

it will output in dot language, which you can then render a graph using graphviz.

I hope this is useful for you guys.

I've done something similar but I used MyState::config(). Is there any benefit using your method vs mine or it's the same?

I'm not sure but my way allows me to show graph according to user roles (which was configured in canTransition method)

That's clever! Thank you for your input.
