Django Oscar Bluelight Specials

This package contains enhancements and improvements to the built-in offers and vouchers features in Django Oscar.

Features

• Group Restricted Vouchers: Bluelight adds the ability to restrict application of vouchers to a specific whitelist of groups (django.contrib.auth.models.Group). For example, you could create a voucher code that can only be applied by users who belong to the group Customer Service Reps.
• Compound Offer Conditions: By default, Oscar only allows assigning a single condition to a promotional offer. Compound offer conditions allow you to create more complex logic around when an offer should be enabled. For example, you could create a compound condition specifying that a basket must contain at least 3 items and have a total value greater than $50.
  • Compound conditions can aggregate an unlimited number of child conditions together.
  • Compound conditions can join their child conditions using either an AND or an OR conjunction.
  • Very complex conditions requiring both AND and OR conjunctions can be modeled by creating multiple levels of compound conditions.
• Parent / Child Voucher Codes: By default Oscar doesn't support bulk creation of voucher codes. Bluelight adds the ability to bulk create any number of child vouchers (with unique, automatically generated codes) for any standard (non-child) voucher. This can be useful when sending voucher codes to customer's through email, as it allows the creation of hundreds or thousands of non-sequential, one-time-use codes.
  • Child codes can be added when creating a new voucher or after a voucher is created.
  • More child codes can be generated for a voucher at any time.
  • Child codes can be exported in CSV and JSON formats.
  • Any time a parent voucher is edited (name changed, benefit altered, etc), all child codes are also updated to match.
  • When a parent voucher is deleted, all children are also deleted.
  • Once a voucher has child codes assigned to it, the parent voucher itself can not be applied by anyone.

Roadmap

• Make child code creation and updating more performant, possibly by (1) extracting some of the work into asynchronous Celery tasks and (2) better tracking of dirty model fields before saving.
• Add ability to duplicate vouchers.
• Add ability to add conditions to vouchers.

Caveats

Bluelight currently works by forking four of Oscar's apps: offer, voucher, dashboard.offers, and dashboard.vouchers. Currently there is no way to use Bluelight if your application has already forked those applications.

Installation

Install [django-oscar-bluelight]{.title-ref}.:

pip install django-oscar-bluelight

Import Bluelight's settings into your projects settings.py file.

from oscar.defaults import *
from oscarbluelight.defaults import *  # Needed so that Bluelight's views show up in the dashboard

Add Bluelight to your installed apps (replacing the equivalent Django Oscar apps). The top-level oscarbluelight app must be defined before the oscar app---if it isn't Django will not correctly find the Bluelight's templates.

INSTALLED_APPS = [
    ...
    # Bluelight. Must come before `django-oscar` so that template inheritance / overrides work correctly.
    'oscarbluelight',
    'thelabdb.pgviews',

    # django-oscar
    'oscar',
    'oscar.apps.analytics',
    'oscar.apps.checkout',
    'oscar.apps.address',
    'oscar.apps.shipping',

    'oscar.apps.dashboard.communications',
    'oscar.apps.dashboard.shipping',
    ...
]

Fork the basket application in your project and add BluelightBasketMixin as a parent class of the Line model.

from oscar.apps.basket.abstract_models import AbstractLine
from oscarbluelight.mixins import BluelightBasketLineMixin

class Line(BluelightBasketLineMixin, AbstractLine):
    pass

from oscar.apps.basket.models import *  # noqa

Usage

After installation, the new functionality will show up in the Oscar dashboard under the Offers menu.
