django-mooch 0.6.0

Install django-mooch using pip and add mooch to your INSTALLED_APPS.

Add a moochers app:

from collections import OrderedDict

from django.conf import settings
from django.conf.urls import include, url

from mooch.banktransfer import BankTransferMoocher
from mooch.postfinance import PostFinanceMoocher
from mooch.stripe import StripeMoocher

from myapp.models import Thing  # Inherit mooch.models.Payment


app_name = 'mooch'  # This is the app namespace.

moochers = OrderedDict((
    ('postfinance', PostFinanceMoocher(
        model=Thing,
        pspid='thing',
        live=False,
        sha1_in=settings.POSTFINANCE_SHA1_IN,
        sha1_out=settings.POSTFINANCE_SHA1_OUT,
        app_name=app_name,
    )),
    ('stripe', StripeMoocher(
        model=Thing,
        publishable_key=settings.STRIPE_PUBLISHABLE_KEY,
        secret_key=settings.STRIPE_SECRET_KEY,
        app_name=app_name,
    )),
    ('banktransfer', BankTransferMoocher(
        model=Thing,
        autocharge=True,  # Mark all payments as successful.
        app_name=app_name,
    )),
]

urlpatterns = [
    url(r'', moocher.urls) for moocher in moochers.values()
]

Include the moochers app / URLconf somewhere in your other URLconfs.

Add a payment page:

def pay(request, id):
    instance = get_object_or_404(Thing.objects.all(), id=id)

    return render(request, 'pay.html', {
        'thing': instance,
        'moochers': [
            moocher.payment_form(request, instance)
            for moocher in moochers.values()
        ],
    })

Maybe send a confirmation mail when charges happen (an example template for this is actually included with the project). Please note that contrary to most other projects, django-mooch uses the moocher instance as sender, not the class:

from mooch.mail import render_to_mail
from mooch.signals import post_charge

# The signal handler receives the moocher instance, the payment and
# the request.
def send_mail(sender, payment, request, **kwargs):
    render_to_mail('mooch/thanks_mail', {
        'payment': payment,
    }, to=[payment.email]).send(fail_silently=True)

# Connect the signal to our moocher instances (moochers may be used
more than once on the same website):
for moocher in moochers.values():
    post_charge.connect(send_mail, sender=moocher)

If you want to differentiate between moochers (for example to send a different mail for bank transfers, because the payment has not actually happened yet) set the sender argument when connecting as follows:

# Some stuff you'll have to imagine... sorry.
post_charge.connect(thank_you_mail, moochers['postfinance'])
post_charge.connect(thank_you_mail, moochers['stripe'])
post_charge.connect(please_pay_mail, moochers['banktransfer'])
