django-netcash 0.2.2

Payment form

netcash.forms.NetcashForm can be used to construct the html form. It is a helper form for html output and it shouldn’t perform any validation.

Example:

# views.py

from django.shortcuts import get_object_or_404
from django.views.generic.simple import direct_to_template
from django.contrib.auth.decorators import login_required

from netcash.forms import NetcashForm

@login_required
def pay_with_netcash(request, order_id)

    # Order model have to be defined by user, it is not a part
    # of django-netcash
    order = get_object_or_404(Order, pk = order_id)

    form = NetcashForm(initial={

        # required params:
        'p3': 'description of the goods',
        'p4': order.total,

        # optional params:

        # 'p10': '/cancel/button/url',
        # 'Budget': 'Y',  # will display the budget option in the Gateway popup
        # 'm_4': 'extra param 1',
        # 'm_5': 'extra param 2',
        # 'm_6': 'extra param 3',
        # 'm_9': order.user.email # cardholder email address
    })

    return direct_to_template(request, 'pay_with_netcash.html', {'form': form})

The template:

{% extends 'base.html' %}

{% block content %}
    <form action="{{ form.target }}" method="POST">
        <p>{{ form.as_p }}</p>
        <p><input type="submit" value="Pay by Credit Card"></p>
    </form>
{% endblock %}

The {{ form.as_p }} output will be a number of <input type='hidden'> tags.

NetcashForm has a ‘target’ attribute with Netcash URL.

Please note that it’s up to you to provide Order model with any fields you want and to implement your order processing logic. Order handling should be performed in netcash.signals.data signal handler.

netcash.signals.data signal

This signal is sent when Netcash posts data to Data URL. Signal subscribers will get an ‘order’ argument with NetcashOrder instance.

Example:

import netcash.signals

def data_received(sender, **kwargs):
    netcash_order = kwargs['order']

    if netcash_order.TransactionAccepted: # order is paid
        amount = netcash_order.Amount
        # your business logic
        # ...
    else: # order is not paid
        # your business logic
        # ...

netcash.signals.data.connect(data_received)

urls.py

In order to get Data URL, Accept URL and Reject URL up and running, include netcash.urls in your urls.py:

urlpatterns = patterns('',
    #...
    url(r'^netcash/', include('netcash.urls')),
    #...
)

Templates

• netcash/accept.html - Accept URL page. Has an ‘order’ variable in template context with NetcashOrder instance.

• netcash/accept.html - Reject URL page. Has an ‘order’ variable in template context with NetcashOrder instance.
