Populating Data

django-exchange supports populating currency and exchange rates using a service provider automatically. Currently it has built in support for openexchangerates.org service. It is only a matter of supplying an api key obtained from http://openexchangerates.org as django settings using the key OPENEXCHANGERATES_API_KEY:

OPENEXCHANGERATES_API_KEY = '<YOU_API_KEY_HERE>'

Now you can populate you currency and exchange rates magically by typing:

$ python manage.py update_exchange_rates

If you want to use you own service provider, you should consider implementing exchange.adapters.BaseAdapter class and pass you implementation class path as an argument to update_exchange_rates command:

$ python manage.py update_exchange_rates -c myproj.providers.MyProvider

Quickstart

Currency conversions is dead easy. There are auxilaray methods helps you calculate conversions using populated exchange rates under exchange.conversions module.

Take a look at the example below:

>>> from exchange.conversion import Price, convert
>>> my_price = Price(50, 'USD')
>>> my_price.convert('YEN')
<Price (4678.50 YEN)>
