at least one NetcashGateway instance in DB.SettingsSpecify your credentials in settings.py:NETCASH_USERNAMENETCASH_PASSWORDNETCASH_PINNETCASH_TERMINAL_NUMBERIf your web server is behind reverse proxy you should also specifyNETCASH_IP_HEADERoption. It’s arequest.METAkey with client ip address
(default is ‘REMOTE_ADDR’).You also have to setup your Netcash account on netcash.co.za. Login into the
admin panel, go to ‘credit cards’ section then go to ‘Adjust Gateway Defaults’
and then paste your Data URL. Data URL can be found in django admin changelist
page for NetcashGateway model.UsagePayment formnetcash.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.Pass all the fields to form ‘initial’ argument. Form also has an optional
‘user’ parameter: it is the User instance the order is purchased by. If
‘user’ is specified, ‘m_9’ (cardholder email address) will be filled
automatically if it is not passed with ‘initial’.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
    }, user=order.user)

    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<inputtype='hidden'>tags.NetcashForm has a ‘target’ attribute with Netcash URL.Please note that it’s up to you to implement the order processing logic.
Order handling should be performed innetcash.signals.datasignal handler.netcash.signals.datasignalWhen Netcash posts data to Data URLnetcash.signals.datasignal is sent.
This signal won’t be sent for suspicious data (when request is coming from
untrusted ip or form validation fails).Signal subscribers will get an ‘order’ argument withNetcashOrderinstance.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
        # ...
