README

Handling status changes of a model is always a pain.

Eloquent Status Mutator provides is a simple trait which enforces correct status changes & some more cool features.

Usage

Define Statuses

Define the statuses of the model in the statuses property:

class Order extends Model
{
    use HasStatus;
    
    protected $statuses = [
        'opened'    => [],
        'paid'      => ['from'     => 'opened'],
        'approved'  => ['from'     => 'paid'],
        'shipped'   => ['from'     => ['paid', 'approved']],
        'arrived'   => ['from'     => 'shipped'],
        'cancelled' => ['not-from' => ['arrived']],
    ];
}

Automatic Status Enforcement

The package makes sure that only listed statuses can be set:

$order->status = 'opened'; // OK

$order->status = 'some other status'; // Throws Exception

Status Flow Validation

The package enforces that status can be set only after defined statuses in its 'from' key

$order->status = 'opened';

$order->status = 'paid'; // OK

$order->status = 'arrived'; // Throws Exception

The package also enforces the 'not-from' status

$order->status = 'arrived';

$order->status = 'cancelled'; // Throws Exception

Helpers

$order->status = 'paid';

if ($order->is('paid')) {
    echo 'The order is shipped';
}

if ($order->canBe('shipped')) {
    echo 'The order can be shipped';
}

Before and After callbacks

In some cases, we need to do something after a specific status is set - for example, send a mail after an order is cancelled. Our package invokes a method after status change by the convention of on + status name (camel cased)

class Order extends Model
{
    use HasStatus;
    
    protected $statuses = [
        'opened'    => [],
        'paid'      => ['from'     => 'opened'],
        'approved'  => ['from'     => 'paid'],
        'shipped'   => ['from'     => ['paid', 'approved']],
        'arrived'   => ['from'     => 'shipped'],
        'cancelled' => ['not-from' => ['arrived']],
    ];
    
    public function onCancelled()
    {
        // Send cancellation mail to the user
    }
}

Installation

• Request the package via composer

composer require laravel-israel/eloquent-status-mutator

• Use HasStatus trait in your model

class Order extends Model
{
    use HasStatus;
}

• Define the available statuses in the model

protected $statuses = [
    'opened'    => [],
    'paid'      => ['from'     => 'opened'],
    'approved'  => ['from'     => 'paid'],
    'shipped'   => ['from'     => ['paid', 'approved']],
    'arrived'   => ['from'     => 'shipped'],
    'cancelled' => ['not-from' => ['arrived']],
];
