Bluelight Specials - Enhancements to the offer and vouchers features for Django Oscar.
Project description
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,
],
...
}
]
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.
Changelog

0.8.1

0.8.0
- Add Concept of System Offer Groups.
System Offer Groups are standard offer groups, but are automatically created and are ensured to always exist. They can not, therefore, be created or deleted via the dashboard UI. They are lazy-created by referencing them in code using the oscarbluelight.offer.groups.register_system_offer_group(slug='foo') function.
Along with this functionality comes the addition of offer and group related signals which can be used to perform actions at specific points in time during offer group application. For example you could create a system offer group for offers which should be applied only after taxes have been calculated. Then you could use the pre_offer_group_apply signal to perform tax calculation on a basket directly before the offer group is applied.
0.7.1
