django-simple-currencies

django-simple-currencies allows you to define different currencies, and includes template tags / filters to allow easy conversion between them.

Setup

Either clone this repository into your project, or install with pip install django-simple-currencies

You'll need to add currencies to INSTALLED_APPS in your project's settings.py file :

INSTALLED_APPS = (
    ...
    'currencies',
)

Add currencies.middleware.CurrencyMiddleware to MIDDLEWARE_CLASSES, must be after django.contrib.sessions.middleware.SessionMiddleware :

MIDDLEWARE_CLASSES = (
    ...    
    'django.contrib.sessions.middleware.SessionMiddleware',
    'currencies.middleware.CurrencyMiddleware',  # must be after 'SessionMiddleware'
    ...
)

If you're going to use site-wide caching, add currencies.middleware.CacheCurrencyMiddleware, but before django.middleware.cache.FetchFromCacheMiddleware :

MIDDLEWARE_CLASSES = (
    ...
    'currencies.middleware.CacheCurrencyMiddleware',  # must be before 'FetchFromCacheMiddleware'
    'django.middleware.cache.FetchFromCacheMiddleware',    
)

Be sure you have the django.core.context_processors.request context processor listed in TEMPLATE_CONTEXT_PROCESSORS :

TEMPLATE_CONTEXT_PROCESSORS = [
    ...
    "django.core.context_processors.request"
]

And don't forget to add this line to your site's root URLConf :

url(r'^currencies/', include('currencies.urls')),

Then run ./manage.py syncdb to create the required database tables

Configuration

django-simple-currencies has built-in integration with Open Exchange Rates

You will need to specify your API key in your settings.py file :

OPENEXCHANGERATES_APP_ID = "c2b2efcb306e075d9c2f2d0b614119ea"

You will then be able to use the management commands currencies and update_rates. The former will import any currencies that are defined on Open Exchange Rates. You can selectively import currencies, for example bellow command will import USD and EUR currencies only :

./manage.py currencies --import=USD --import=EUR

The update_rates management command will update all your currencies against the rates returned by Open Exchange Rates. Any missing currency will be left untouched.

Usage

First of all, load the currencies in every template where you want to use it :

{% load currencies %}

to get a list of the active currencies :

{% get_currencies as CURRENCIES %}

to get the currently set currency :

{% get_current_currency as CURRENCY %}

and then to convert to a given currency :

{% change_currency [amount] [currency_code] %}

or use the filter :

{{ [amount]|currency:[currency_code] }}

Please see example application. This application is used to manually test the functionalities of this package. This also serves as a good example.

You need only Django 1.4 or above to run that. It might run on older versions but that is not tested.
