django-inventory

Simple inventory management for Django objects using the contenttypes framework.

Installation

1. Add inventory to the INSTALLED_APPS tuple in settings.py.

    INSTALLED_APPS = (
        # ...
        'inventory',
    )
   

2. Synchronize the database:

    ./manage.py syncdb
   

Usage

An InvetoryItem object typically represents a physical item being inventoried such as a product. The InvetoryItem object must be created before performing transactions that add or remove quantities of that item.

InvetoryItem objects can be created in the admin interface or through code. When creating an InvetoryItem, the content_object associates any Django model with the inventory item. For example, an project which has a Product model to represent products sold on a website might create an InvetoryItem for that product as follows:

from inventory.models import InventoryItem, StockStatus

stockstatus = StockStatus.objects.get(name="In Stock")
product = Product() 
item = InventoryItem(sku="0001", content_object=product, 
                     stock_status=stockstatus)
item.save()

Once an InventoryItem exists, inventory "transactions" can be performed on the item to increment or decrement the quantity. Using transactions allows better tracking of items in and out of inventory and cost of goods sold.

Tips

• The django-genericadmin project can be used to add better support for the generic relationships in Django's admin interface.
