Overview
from django.db import models
from easymoney import MoneyField
class MyModel(models.Model):
price = MoneyField(default=3.14)
other_price = MoneyField(default=1)
obj = MyModel()
print obj.price # -> $3.14
# Money arithmetic
obj.price + obj.other_price # $4.14
# Mix with ints and floats
obj.price + 1 # $4.14
obj.price + 0.2 # $3.34
# No partial cents or crazy floats
obj.price / 3 # $1.05Settings
A primary use of easymoney is global currency defined in settings with global formatting and precision. Here is how you do that:
# These are default settings, code and locales refer to ones used in babel library
CURRENCY_CODE = 'USD'
CURRENCY_LOCALE = 'en_US'
CURRENCY_DECIMAL_PLACES = 2
# This is optional, for cases when you want to use some fake currency
CURRENCY_FORMAT = '# points'Several currencies
One money field can't store different currencies, however, you can create different money classes and model fields for them:
from easymoney import Money, MoneyField
class GameMoney(Money):
# CODE = '...'
# LOCALE = '...'
DECIMAL_PLACES = 0
FORMAT = '# points'
class GameMoneyField(MoneyField):
MONEY_CLASS = GameMoney
