README

Imagine you want to have an Eloquent model hold a status. It's easily solved by just adding a status field to that model and be done with it. But in case you need a history of status changes or need to store some extra info on why a status changed, just adding a single field won't cut it.

This package provides a HasStatuses trait that, once installed on a model, allows you to do things like this:

// set a status
$model->setStatus('pending', 'needs verification');

// set a status using an enum
$model->setStatus(UserStatus::pending);

// set another status
$model->setStatus('accepted');

// specify a reason
$model->setStatus('rejected', 'My rejection reason');

// get the current status
$model->status(); // returns an instance of \Spatie\ModelStatus\Status

// get the previous status
$latestPendingStatus = $model->latestStatus('pending');

$latestPendingStatus->reason; // returns 'needs verification'

Installation

You can install the package via composer:

composer require spatie/laravel-model-status

You must publish the migration with:

php artisan vendor:publish --provider="Spatie\ModelStatus\ModelStatusServiceProvider" --tag="migrations"

Migrate the statuses table:

php artisan migrate

Optionally you can publish the config-file with:

php artisan vendor:publish --provider="Spatie\ModelStatus\ModelStatusServiceProvider" --tag="config"

This is the contents of the file which will be published at config/model-status.php

return [

    /*
     * The class name of the status model that holds all statuses.
     *
     * The model must be or extend `Spatie\ModelStatus\Status`.
     */
    'status_model' => Spatie\ModelStatus\Status::class,

    /*
     * The name of the column which holds the ID of the model related to the statuses.
     *
     * You can change this value if you have set a different name in the migration for the statuses table.
     */
    'model_primary_key_attribute' => 'model_id',

];

Usage

Add the HasStatuses trait to a model you like to use statuses on.

use Spatie\ModelStatus\HasStatuses;

class YourEloquentModel extends Model
{
    use HasStatuses;
}

Set a new status

You can set a new status like this:

$model->setStatus('status-name');

A reason for the status change can be passed as a second argument.

$model->setStatus('status-name', 'optional reason');

setStatus and forceSetStatus also accept enums:

enum UserStatus: string
{
    case pending = 'pending';
    case accepted = 'accepted';
}

$model->setStatus(UserStatus::pending);

Backed enums are stored using their value. Unit enums are stored using their case name.

Restrict statuses to an enum

You can restrict which statuses a model accepts by overriding the statusEnumClass method:

class YourEloquentModel extends Model
{
    use HasStatuses;

    public function statusEnumClass(): ?string
    {
        return UserStatus::class;
    }
}

When statusEnumClass() returns an enum class, setStatus(...) only accepts statuses that belong to that enum. forceSetStatus(...) always bypasses this validation.

Retrieving statuses

You can get the current status of model:

$model->status; // returns a string with the name of the latest status

$model->status(); // returns the latest instance of `Spatie\ModelStatus\Status`

$model->latestStatus(); // equivalent to `$model->status()`

$model->statusEnum(); // returns the latest enum case when statusEnumClass() is configured, otherwise null

statusEnum() also returns null when there is no status yet, or when the latest stored status does not map to the configured enum.

You can also get latest status of a given name:

$model->latestStatus('pending'); // returns an instance of `Spatie\ModelStatus\Status` that has the name `pending`

Get all available status names for the model.

$statusNames = $model->getStatusNames(); // returns a collection of all available status names.

The following examples will return statusses of type status 1 or status 2, whichever is latest.

$lastStatus = $model->latestStatus(['status 1', 'status 2']);

// or alternatively...
$lastStatus = $model->latestStatus('status 1', 'status 2');

All associated statuses of a model can be retrieved like this:

$allStatuses = $model->statuses;

This will check if the model has status:

$model->setStatus('status1');

$isStatusExist = $model->hasStatus('status1'); // return true
$isStatusExist = $model->hasStatus('status2'); // return false

Retrieving models with a given latest state

The currentStatus scope will return models that have a status with the given name.

$allPendingModels = Model::currentStatus('pending');

//or array of statuses
$allPendingModels = Model::currentStatus(['pending', 'initiated']);
$allPendingModels = Model::currentStatus('pending', 'initiated');

Retrieving models without a given state

The otherCurrentStatus scope will return all models that do not have a status with the given name, including any model that does not have any statuses associated with them.

$allNonPendingModels = Model::otherCurrentStatus('pending');

You can also provide an array of status names to exclude from the query.

$allNonInitiatedOrPendingModels = Model::otherCurrentStatus(['initiated', 'pending']);

// or alternatively...
$allNonInitiatedOrPendingModels = Model::otherCurrentStatus('initiated', 'pending');

Validating a status before setting it

You can add custom validation when setting a status by overwriting the isValidStatus method:

public function isValidStatus(string $name, ?string $reason = null): bool
{
    ...

    if (! $condition) {
        return false;
    }

    return true;
}

If isValidStatus returns false a Spatie\ModelStatus\Exceptions\InvalidStatus exception will be thrown.

You may bypass validation with the forceSetStatus method:

$model->forceSetStatus('invalid-status-name');

Check if status has been assigned

You can check if a specific status has been set on the model at any time by using the hasEverHadStatus method:

$model->hasEverHadStatus('status 1');

Check if status has never been assigned

You can check if a specific status has never been set on the model at any time by using the hasNeverHadStatus method:

$model->hasNeverHadStatus('status 1');

Delete status from model

You can delete any given status that has been set on the model at any time by using the deleteStatus method:

Delete single status from model:

$model->deleteStatus('status 1');

Delete multiple statuses from model at once:

$model->deleteStatus(['status 1', 'status 2']);

Events

TheSpatie\ModelStatus\Events\StatusUpdated event will be dispatched when the status is updated.

namespace Spatie\ModelStatus\Events;

use Illuminate\Database\Eloquent\Model;
use Spatie\ModelStatus\Status;

class StatusUpdated
{
    /** @var \Spatie\ModelStatus\Status|null */
    public $oldStatus;

    /** @var \Spatie\ModelStatus\Status */
    public $newStatus;

    /** @var \Illuminate\Database\Eloquent\Model */
    public $model;

    public function __construct(?Status $oldStatus, Status $newStatus, Model $model)
    {
        $this->oldStatus = $oldStatus;

        $this->newStatus = $newStatus;

        $this->model = $model;
    }
}

Custom model and migration

You can change the model used by specifying a class name in the status_model key of the model-status config file.

You can change the column name used in the status table (model_id by default) when using a custom migration where you changed that. In that case, simply change the model_primary_key_attribute key of the model-status config file.

Testing

This package contains integration tests that are powered by orchestral/testbench.

You can run all tests with:

composer test
