django-oscar-bluelight 0.5.2

Bluelight Specials - Enhancements to the offer and vouchers features for Django Oscar.

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.:

$ pip install django-oscar-bluelight

Import Bluelight’s settings into your projects settings.py file.:

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

Add Bluelight to your install apps.:

INSTALLED_APPS = [
    ...
] + get_core_apps([
    ...
    'oscarbluelight.dashboard.offers',
    'oscarbluelight.dashboard.vouchers',
    'oscarbluelight.offer',
    'oscarbluelight.voucher',
    ...
])

Add Bluelight’s template directory directly before Oscar’s.:

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [
            BLUELIGHT_TEMPLATE_DIR,
            OSCAR_MAIN_TEMPLATE_DIR,
        ],
        ...
    }
]

Usage

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