Oscar - Flexible e-commerce on Django

Named after Oscar Peterson (http://en.wikipedia.org/wiki/Oscar_Peterson), oscar is a Django implementation of Taoshop (a product from Tangent Labs). It’s fairly experimental at the moment. It aims to be a flexible ecommerce application, built

Aims of project

• To be a portable Django application that provides ecommerce functionality.
  
• To comprise a set of loosely coupled apps that can be overridden in projects (interdependence is on interfaces only)
• To allow core objects (eg products, orders) to be extended within a specific project

The central aim is to provide a solid core of an ecommerce project that can be extended and customised to suit the domain at hand. One way to acheive this is to have enormous models that have fields for every possible variation; however, this is unwieldy and ugly. A more elegant solution is to have models where all the fields are meaningful within the ecommerce domain. In general, this means more work up front in terms of creating the right set of models but leads ultimately to a much cleaner and coherent system.

Installation for developers

Set up virtualenv if you haven’t already done so:

sudo apt-get install python-setuptools
sudo easy_install pip
sudo pip install virtualenv virtualenvwrapper
echo "source /usr/local/bin/virtualenvwrapper.sh" >> ~/.bashrc

Reload bash with the following command:

~/.bashrc

Do the following from your workspace folder:

mkdir oscar
cd oscar
mkvirtualenv --no-site-packages oscar

After checking out your fork, install all dependencies:

workon oscar
pip install -r requirements.txt

Now create a local_settings.py file which contains details of your local database that you want to use for development. Be sure to create two databases: one for development and one for running the unit tests (prefix test_ on the normal db name).

Create your database:

./manage.py syncdb

Developing

There is a shortcut script for dropping all of oscar’s apps and rerunning syncdb

./reset_oscar_tables.sh

Run tests using:

./run_tests.sh

This specifies a sqlite3 database to use for testing and filters out the useless output.

You can also use the functionality from django-test-extensions which is one of the installed app

Look in the TODO file for things to hack on…
