Django Currency Conversion

Question

Is there any facility in Django for doing currency conversions? Obviously, rates change day by day but I'm somewhat hopeful that the locale module has some sort of web-service based converter.

There's a snippet here that handles the formatting: http://www.djangosnippets.org/snippets/552/ But I need to localize the values first.

Probably more elegant ways to do this, but it works.

currency_in = 'USD'
currency_out = 'NOK'
import urllib2
req = urllib2.urlopen('http://finance.yahoo.com/d/quotes.csv?e=.csv&f=sl1d1t1&s='+currency_in+currency_out+'=X')
result = req.read()
# result = "USDNOK=X",5.9423,"5/3/2010","12:39pm"

Then you can split() the result for the modifier.

Thanks, this works! I hackishly put this in my settings.py, storing the result as USD_TO_EUR (what I needed), and then the code can access this anywhere. With a cron to SIGHUP gunicorn daily (I already had this), this will get updated at least that often. – mrooney Sep 21 '12 at 19:27

# Install google-currency package

# pip install google-currency

>>> from google_currency import convert  

>>> convert('usd', 'bdt', 1)

Output:

{"from": "USD", "to": "BDT", "amount": "85.30", "converted": true}

You could use django-money app for currency conversions in Django-based projects.

It works with different rate sources and provides an interface to perform conversions & money localization:

>>> # After app setup & adding rates to the DB
>>> from djmoney.money import Money
>>> from djmoney.contrib.exchange.models import convert_money
>>> value = Money(100, 'EUR')
>>> converted = convert_money(value, 'USD')
>>> converted
<Money: 122.8184375038380800 USD>
>>> str(converted)
US$122.82

Formats are easily customizable, you could find the documentation on the project page.

I tried this but I get an error MissingRate at /customer Rate EUR -> USD does not exist. I opened a question: https://stackoverflow.com/questions/66867845/how-to-solve-missingrate-error-in-django — edche, Mar 30 '21 at 11:16

You can use django-money to handle money values including the conversion of currencies as shown below. *The example below converts 100 USD to ... EUR and if using celery beat, you can automatically update the exchange rates of currencies:

# "views.py"

from django.http import HttpResponse
from app.models import MyModel
from djmoney.contrib.exchange.models import convert_money
from djmoney.money import Money

def test(request):
    print(convert_money(Money(100, 'USD'), 'EUR')) # Here
    return HttpResponse("Test")

You can see my answer and django-money doc which explain more about how to convert currencies and how to automatically update the exchange rates of currencies with celery beat..
