This package adds state support to models. It combines concepts from the state pattern and state machines.
It is recommended that you're familiar with both patterns if you're going to use this package.
To give you a feel about how this package can be used, let's look at a quick example.
Imagine a model
Payment, which has three possible states:
Failed. This package allows you to represent each state as a separate class, handles serialization of states to the database behind the scenes, and allows for easy and controller state transitions.
For the sake of our example, let's say that, depending on the state, a the color of a payment should differ.
Here's what the
Payment model would look like:
class Payment extends Model
protected function registerStates(): void
->allowTransition(Pending::class, Failed::class, PendingToFailed::class);
This is what the abstract
PaymentState class would look like:
abstract class PaymentState extends State
abstract public function color(): string;
Here's a concrete implementation of one state, the
class Paid extends PaymentState
public function color(): string
And here's how it it used:
$payment = Payment::find(1);
There's a lot more to tell about how this package can be used. So let's dive in.
