Productory E-commerce

CI PyPI Python Django License

Reusable Django e-commerce building blocks with a working demo: catalog, checkout/orders, promotions, and store pricing config.

Dark Mode Dashboard Light Mode Dashboard

• Package-first architecture (src/) you can install into your own Django project
• Service-layer business logic (pricing, checkout, order transitions) instead of fat views
• DB-backed store defaults for currency, timezone, VAT, and VAT-inclusive/exclusive pricing
• Working demo project (demo/) with seeded realistic data and branded admin KPI dashboard
• Clear extension points: hooks/signals, optional webhooks, and custom pricing orchestration

make install-dev
make demo-run

make install-dev bootstraps a local .venv and installs dev dependencies into it.

Then:

• Catalog products API: http://127.0.0.1:8010/api/catalog/products/
• Checkout carts API: http://127.0.0.1:8010/api/checkout/carts/
• Promotions API: http://127.0.0.1:8010/api/promotions/promotions/
• Create admin: make superuser
• Admin dashboard: http://127.0.0.1:8010/admin/

make demo-run builds containers, applies migrations, and seeds:

• 10 categories
• 10 collections
• 50 products
• stock records (qty 5-10)
• 6 bundles
• 5 active promotions (valid through month end)
• 10 addresses
• 32 carts (open/converted/abandoned mix)
• 18 orders (submitted/paid/fulfilled/canceled mix)

Default store config seeded in DB:

• currency: ZAR
• timezone: Africa/Johannesburg
• VAT: 15%
• pricing mode: VAT-inclusive by default

Useful commands:

make demo-logs
make demo-stop
make loaddata
make test
make test-all

Mounted under path("api/", include("productory_ecommerce.urls")):

• /api/catalog/ -> productory_catalog
• /api/checkout/ -> productory_checkout
• /api/promotions/ -> productory_promotions
• /api/internal/ -> productory_core (staff-only KPI endpoint)

pip install productory-ecommerce

Optional Postgres driver:

pip install "productory-ecommerce[postgres]"

from django.urls import include, path
INSTALLED_APPS = [
 "rest_framework",
 "django_filters",
 "productory_core",
 "productory_catalog",
 "productory_checkout",
 "productory_promotions",
]
urlpatterns = [
 path("api/", include("productory_ecommerce.urls")),
]

Productory Architecture

Productory ERD

• Category: A product group (for example: Coffee Beans, Mugs).
• Collection: A curated shelf of products (for example: Best Sellers, New Arrivals).
• Product: A single item you sell with a SKU, price, and currency.
• StockRecord: The current inventory level for one product.
• ProductImage: Images shown for a product.
• Bundle: A packaged offer made from multiple products sold together at a bundle price.
• BundleItem: The link that says which products are inside a bundle and in what quantity.
• Promotion: A discount rule (percentage or fixed amount) that can target products, bundles, or all products.
• Cart: A shopper’s active basket before checkout.
• CartItem: One product line inside a cart (with quantity and captured unit price).
• Order: The finalized purchase created from a cart at checkout.
• OrderItem: One line in the order snapshot, preserving what was bought and at what price.
• Address: Shipping and billing details attached to orders.
• Currency, TaxRate, StoreConfig: Store-wide defaults that control money format, VAT/tax, and pricing behavior.
• AuditEvent: A timeline entry that records what changed, who changed it, and when it happened.

How it all connects in practice:

• You organize products with categories and collections.
• Products have stock and images.
• You can sell products directly, or group them into bundles.
• Promotions can discount products and bundles.
• A customer adds products to a cart.
• Checkout turns the cart into an order.
• Orders keep a snapshot of purchased items and pricing, plus shipping/billing addresses.
• Store configuration provides the currency and tax rules used during pricing and checkout.
• Every important pricing/ops record writes to the audit trail so admins can review change history.

Tracked models with signal-based audit logging:

• Currency
• TaxRate
• StoreConfig
• Order
• StockRecord
• Bundle
• Promotion

Each AuditEvent stores:

• what changed: field-level before/after values (or relation updates)
• who changed it: authenticated actor when available
• when: event timestamp
