Provides support for models:
from django.db import models
from django_prices.models import AmountField, PriceField
class Product(models.Model):
name = models.CharField('Name')
price_net = AmountField(
'net', currency='BTC', default='5', max_digits=9,
decimal_places=2)
price_gross = AmountField(
'gross', currency='BTC', default='5', max_digits=9,
decimal_places=2)
price = PriceField(net_field='price_net', gross_field='price_gross')And forms:
from django import forms
from django_prices.forms import Amount, PriceField
class ProductForm(forms.Form):
name = forms.CharField(label='Name')
price_net = AmountField(label='net', currency='BTC')And templates:
{% load prices %}
<p>Price: {{ foo.price.gross|amount }} ({{ foo.price.net|amount }} + {{ foo.price.tax|amount }} tax)</p>Note: for template tags to work, you need to add django_prices to your INSTALLED_APPS.
You can also install the wonderful babel library and get proper currency symbols with prices_i18n. First install BabelDjango:
$ pip install BabelDjango
Then follow the instruction to add it to your INSTALLED_APPS and MIDDLEWARE_CLASSES. Finally load the localized template tags:
{% load prices_i18n %}
<p>Price: {{ foo.price.gross|amount }} ({{ foo.price.net|amount }} + {{ foo.price.tax|amount }} tax)</p>You can also use HTML output from prices_i18n template tags, they will wrap currency symbol in a <span> element:
{% load prices_i18n %}
<p>Price: {{ foo.price.gross|amount:'html' }} ({{ foo.price.net|amount:'html' }} + {{ foo.price.tax|amount:'html' }} tax)</p>It will be rendered as a following structure (for example with English locale):
<span class="currency">$</span>15.00Batteries included: django-prices comes with South migration support.
