Integration between django-oscar and the CCH Sales Tax Office SOAP API.
This package is to handle integration between django-oscar based e-commerce sites and the CCH Sales Tax Office SOAP API.
You must fork the order application from Oscar to enable tax calculation as part of placing an order.
Persistence of tax details, while optional, requires that your project uses PostgreSQL. It relies on the HStore field.
Install the instrumented-soap and django-oscar-cch packages.:
$ pip install git+https://gitlab.com/thelabnyc/instrumented-soap.git#r1.0.0 $ pip install git+https://gitlab.com/thelabnyc/django-oscar-cch.git#r1.0.0
Add cch to your INSTALLED_APPS:
# myproject/settings.py ... INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'django.contrib.postgres', ... 'cch', ... ] + get_core_apps([ ... ]) ...
Add some attributes to settings.py to configure how the application should connect to CCH.:
# myproject/settings.py # Add this is you need to connect to the SOAP API through an HTTP Proxy SOAP_PROXY_URL = ... # Configure the CCH WSDL location, entity, and division code CCH_WSDL = ... CCH_ENTITY = ... CCH_DIVISION = ... # Provide either a product SKU or a product group and item to send to CCH when calculating taxes CCH_PRODUCT_SKU = ... CCH_PRODUCT_GROUP = ... CCH_PRODUCT_ITEM = ...
Install extra fields on order.models.Order and order.models.Line (see also How to fork Oscar apps).:
# order/models.py from cch.mixins import CCHOrderMixin, CCHOrderLineMixin from oscar.apps.order.abstract_models import AbstractOrder, AbstractLine class Order(CCHOrderMixin, AbstractOrder): pass class Line(CCHOrderLineMixin, AbstractLine): pass from oscar.apps.order.models import * # noqa
Create and run migrations for the order app.:
$ python managy.py makemigrations order $ python managy.py migrate
Add the CCH mixin to order.utils.OrderCreator.:
# order/utils.py from cch.mixins import CCHOrderCreatorMixin from oscar.apps.order import utils class OrderCreator(CCHOrderCreatorMixin, utils.OrderCreator): pass
