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). But also watches the level of stock of a model and sends a notification via Email

This package was originally a fork form laravel-stock

Functionality

• Increase stocks
• Decrease stocks
• Clear stocks
• Set stocks
• Check if model has stock or not (on a certain date/time).
• Send notification when a pre-defined stock level is reached

Installation

You can install the package via composer:

composer require mendela92/laravel-stock

By running php artisan vendor:publish --provider="Mendela92\Stock\StockServiceProvider", it will publish migrations and config file.

The configuration file looks this:

<?php

use Mendela92\Stock\Notifications\LowStockLevelNotification;

return [

    /*
    |--------------------------------------------------------------------------
    | Default table name
    |--------------------------------------------------------------------------
    |
    | Table name to use to store mutations.
    |
    */

    'table' => 'stocks',

    /*
   |--------------------------------------------------------------------------
   | Default notification stock level
   |--------------------------------------------------------------------------
   |
   | Default stock alert configuration values
   |
   */
    'alert' => [

        'notification' => env("STOCK_NOTIFICATION", true),

        'at' => env("NOTIFICATION_STOCK_LEVEL", 10),

        'to' => ['email@example.com'],

        'model' => LowStockLevelNotification::class,
    ],
];

Run php artisan migrate to migrate the table. There will now be a stocks table in your database.

Usage

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

use Mendela92\Stock\HasStock;

class Book extends Model
{
    use HasStock;
    
    ...
    
    public function getStockAlertAt(): mixed
    {
        return config('stock.alert.at', 10);
        // Change the value of the level of stock before being notification is sent.
    }

    public function getStockAlertTo(): mixed
    {
        // Array of emails that the notifications will be sent to.
    }

    public function getStockNotificationStatus(): mixed
    {
        // Conditioning notification of  status for each model instance
    }
}

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
