README

Keep stock for Eloquent models. This package will track stock mutations for your models. You can increase, decrease, clear and set stock. It's also possible to check if a model is in stock (on a certain date/time).

Installation

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.

Usage

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

use Appstract\Stock\HasStock;

class Book extends Model
{
    use HasStock;
}

Basic mutations

$book->increaseStock(10);
$book->decreaseStock(10);
$book->mutateStock(10);
$book->mutateStock(-10);

Clearing stock

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

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

Setting stock

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

$book->setStock(10);

Check if model is in stock

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

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

Current stock

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

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

Stock arguments

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

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

Query Scopes

It is also possible to query based on stock.

Book::whereInStock()->get();
Book::whereOutOfStock()->get();

Testing

composer test
