Laravel Stock

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 inquid/laravel-stock

By running php artisan vendor:publish --provider="Inquid\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.

The configuration file looks this:

<?php

return [

    /*
    |--------------------------------------------------------------------------
    | Default table name
    |--------------------------------------------------------------------------
    |
    | Table name to use to store mutations.
    |
    */
    
    'table' => 'stock_mutations',
    
    'stock_mutation_model' => Inquid\Stock\StockMutation::class,
    
    //'special_date_class' => \MongoDB\BSON\UTCDateTime::class,
];

Usage

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

Note: If you need to use a custom Model for example for MongoDB you can update the model to use in the config file stock.php.

use Inquid\Stock\HasStock;

class Book extends Model
{
    use HasStock;
}

Basic mutations

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

With warehouse support

$book->increaseStock(10, ['warehouse' => $warehouse_first]);
$book->decreaseStock(10, ['warehouse' => $warehouse_first]);
$book->mutateStock(10, ['warehouse' => $warehouse_first]);
$book->mutateStock(-10, ['warehouse' => $warehouse_first]);

Clearing stock

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

$book->clearStock();
$book->clearStock(10);
// With warehouse
$book->clearStock(10, ['warehouse' => $warehouse_first]);

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);

With warehouse

$book->inStock(); // anywhere
$book->inStock(10);
$book->inStock(10, ['warehouse' => $warehouse_first]);

Current stock

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

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

Note: If you are using MongoDb you need to set the date class in the config file. 'special_date_class' => \MongoDB\BSON\UTCDateTime::class,

Current stock in specific warehouse

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

$book->stock(null, ['warehouse' =>$warehouse_first]);
$book->stock(Carbon::now()->subDays(10), ['warehouse' =>$warehouse_first]);

Move between warehouses

Move amount from source warehouse to destination warehouse.

$book->moveBetweenStocks(5,$warehouse_first, $warehouse_second);

Stock arguments

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

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

With warehouse

$book->setStock(10, ['warehouse' => $warehouse_first]);

Query Scopes

It is also possible to query based on stock.

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

Testing

composer test
