from prices import Price
from django_prices_openexchangerates import exchange_currency

print(converted_price)
# Price('8.84040', currency='EUR')
print(converted_price.history)
# (Price('10', currency='USD') | CurrencyConversion('USD', 'EUR', rate=Decimal('0.88404')))It will also create additional steps if it cannot convert directly:
from prices import Price
from django_prices_openexchangerates import exchange_currency
converted_price = exchange_currency(Price(10, currency='GBP'), 'EUR')
print(converted_price)
# Price('13.31313588062401085236264978', currency='EUR')
print(converted_price.history)
# ((Price('10', currency='GBP') | CurrencyConversion('GBP', 'USD', rate=Decimal('1.507272590247946341095787173'))) | CurrencyConversion('USD', 'EUR', rate=Decimal('0.88326')))Templatetags can be used to convert currency and round amounts:
{% load prices_multicurrency %}
<p>Price: {% gross_in_currency foo.price 'USD' %} ({% net_in_currency foo.price 'USD' %} + {% tax_in_currency foo.price 'USD' %} tax)</p>When you install babel-django library, you can use i18n templatetags and display proper currency symbols
{% load prices_multicurrency_i18n %}
<p>Price: {% gross_in_currency foo.price 'USD' %} ({% net_in_currency foo.price 'USD' %} + {% tax_in_currency foo.price 'USD' %} tax)</p>First install the package:
pip install django-prices-openexchangerates
Then add 'django_prices_openexchangerates' to your INSTALLED_APPS.
