djangoshop-currencies

Django-SHOP integration with django-currencies

Introduction

This module allows Django-SHOP implementations to integrate live currency feeds. This will allow you to offer your shop product prices in the user’s chosen currency.

The module is currently compatible with Django v1.10.7. This documentation assumes a working knowledge of Django and Django-SHOP.

Release History

0.2.x - Django-SHOP v0.11.x compatibility
0.1.x - Django-SHOP v0.10.2 compatibility

TODO

Please let me know of you have any feature suggestions, or wish to implement any of the below:

Fix for the db initialisation warning below.
Tests.
Continuous build integration including compatibility testing with various python, Django and Django-SHOP versions.

Configuration

Follow the Readme for django-currencies. Install this module through pip: pip install djangoshop-currencies.

The Django-SHOP Money system has been extended to use django-currencies as a currency conversion backend. To enable this functionality your currencies configuration must satisfy the following requirements:

ISO4217Exponent and symbol populating using ./manage.py currencies iso (This automatically imports the currencies set in the SHOP_CURRENCIES setting)
Currency factors populating using ./manage.py updatecurrencies yahoo (This also sets the base currency to SHOP_DEFAULT_CURRENCY)
Some currencies set to active in the admin interface

Warning

The currencies database table must be initialised before any Django app can import the included money types. Unfortunately the ./manage.py command will automatically import a lot of modules when they are configured in INSTALLED_APPS causing an error which prevents you from running ./manage.py migrate, etc.

As a workaround before a permanent solution is found:

Create a minimal settings file which will be used temporarily to allow the currencies table of your database to be populated. As an example, one is included here.
Run python manage.py migrate --settings shop_currencies.min_settings (or use your minimal settings file)
Satisfy requirements 1. & 2. above & append --settings <min_settings> to the commands
Run python manage.py migrate
Run python manage.py createsuperuser to create an admin user
Satisfy requirement 3. above

Once created, I recommend dumping your base currency as a fixture for subsequent use when initialising databases:

python manage.py dumpdata --indent 2 --output fixtures/currency.json --pks 1 currencies.currency
python manage.py loaddata --settings shop_currencies.min_settings fixtures/currency.json

Usage

Replace the DefaultCartModifier with the provided CurrencyCartModifier in your shop settings:

SHOP_CART_MODIFIERS = (
    # provides the default cart lines
    'shop_currencies.modifiers.CurrencyCartModifier',
    ...

Use the Money conversion extension which provides the to(code) function as below. The additional base argument is used by the cart modifier.

from django.db import models
from currencies.utils import get_currency_code
from shop_currencies.money.fields import MoneyField

class MyModel(models.Model):
    unit_price = MoneyField()
    ...

    def get_price(self, request, base=False):
        if base:
            return self.unit_price
        else:
            session_currency_code = get_currency_code(request)
            return self.unit_price.to(session_currency_code)
