2.  cartridge

Cartridge is a shopping cart application built using the Django framework. It is BSD licensed, and designed to provide a clean and simple base for developing e-commerce websites. It purposely does not include every conceivable feature of an e-commerce website; instead, Cartridge focuses on providing core features common to most e-commerce websites.

This specific focus stems from the idea that every e-commerce website is different, is tailored to the particular business and products at hand, and should therefore be as easy to customize as possible. Cartridge achieves this goal with a code-base that is as simple as possible and implements only the core features of an e-commerce website.

Cartridge extends the Mezzanine content management platform. A live demo of Cartridge can be found by visiting the Mezzanine live demo.

Dependencies

Cartridge is designed as a plugin for the Mezzanine content management platform, and therefore requires Mezzanine to be installed. The integration of the two applications should occur automatically by following the installation instructions below.

Installation

The easiest method is to install directly from PyPI using pip by running the command below, which will also install the required dependencies mentioned above:

$ pip install -U cartridge

Otherwise, you can download Cartridge and install it directly from source:

$ python setup.py install

Once installed, the command mezzanine-project can be used to create a new Mezzanine project, with Cartridge installed, in similar fashion to django-admin.py:

$ mezzanine-project -a cartridge project_name
$ cd project_name
$ python manage.py createdb --noinput
$ python manage.py runserver

Here we specify the -a switch for the mezzanine-project command, which tells it to use an alternative package (cartridge) for the project template to use. Both Mezzanine and Cartridge contain a project template package containing the settings.py and urls.py modules for an initial project. If you'd like to add Cartridge to an existing Mezzanine or Django project, you'll need to manually configure these yourself. See the FAQ section of the Mezzanine documentation for more information.

Note

The createdb command is a shortcut for using Django's migrate command, which will also install some demo content, such as a contact form, image gallery, and more. If you'd like to omit this step, use the --nodata option with createdb.

You should then be able to browse to http://127.0.0.1:8000/admin/ and log in using the default account (username: admin, password: default). If you'd like to specify a different username and password during set up, simply exclude the --noinput option included above when running createdb.

3.  django-oscar

Oscar is an e-commerce framework for Django designed for building domain-driven sites. It is structured such that any part of the core functionality can be customised to suit the needs of your project. This allows a wide range of e-commerce requirements to be handled, from large-scale B2C sites to complex B2B sites rich in domain-specific business logic.

4.  django-SHOP

Django-SHOP aims to be a the easy, fun and fast e-commerce counterpart to django-CMS.


Build the database model out of the product's properties – not vice versa

Most e-commerce systems are shipped with a predefined database model for products. But products can vary a lot, and it simply is impossible to create a model which fits for all of them. This is esspecially true for products with a hierarchy of variants. In many popular e-commerce platforms, you either have far too many attributes per product, and/or the really required attributes are missing.

In django-SHOP implementations, the product models reflect their pysical properties making it possible to create complete and deep hierarchies of variations, but without having to fiddle with unneeded properties. It furthermore avoids the need for an Entity Attribute Value Model, which is considered a database anti-pattern, because it produces far too many table joins, when filtering by property.

Don't build pages using hard-coded templates – compose them

With the advent of frameworks, such as Angular, React, Vue and Aurelia, building web-applications shifted from a page-centric to a component-based approach.

In django-SHOP, you are in full control over the page's layout, since all components are encapsulated and independent from each other. This means that instead of adopting the Catalog, Cart, Checkout and Order pages, use the django-CMS plugin system to compose everything required for those pages.
