You can install the package via composer:

composer require appstract/laravel-stock

By running php artisan vendor:publish --provider="Appstract\Stock\StockServiceProvider" in your project all files for this package will be published. Run php artisan migrate to migrate the table. There will now be a stock_mutations table in your database.

Adding the HasStock trait will enable stock functionality on the Model.

use Appstract\Stock\HasStock;  class Book extends Model {  use HasStock; }

It’s also possible to clear the stock and directly setting a new value.

$book->clearStock(); $book->clearStock(10);

It is possible to set stock. This will create a new mutation with the difference between the old and new value.

It’s also possible to check if a product is in stock (with a minimal value).

$book->inStock(); $book->inStock(10);

Get the current stock value (on a certain date).

$book->stock; $book->stock(Carbon::now()->subDays(10));

Add a description and/or reference model to de StockMutation.

$book->increaseStock(10, [  'description' => 'This is a description',  'reference' => $otherModel, ]);
