Spgateway for Django

Write Django and your store as usual, and let django-spgateway handle your transactions with Spgateway

Requirements

• Python 3.7
• Django 2.1
• pycrypto 2.6.1
• We only tested on environment as below

Installation

1. Install using pip or pipenv:

   pip install django-spgageway

   Alternatively, you can install download or clone this repo and call pip install -e ..

2. Add to INSTALLED_APPS in your settings.py:

   'spgateway',

3. Add settings in your settings.py:

   SPGATEWAY_PROFILE = {
       'YOUR_MerchantID': {
           'MerchantID': 'YOUR_MerchantID',
           'HashKey': 'YOUR_HashKey',
           'HashIV': 'YOUR_HashIV',
       },
   }
   SPGATEWAY_MERCHANTID = 'YOUR_MerchantID'
   SPGATEWAY_ORDERMODEL = 'yourapp.Order'

4. Add urlpattern into your urls.py:

   path('spgateway/', include('spgateway.urls')), for Django 2

   url(r'^spgateway/', include('spgateway.urls')), for Django 1

5. Import from spgateway.models import SpgatewayOrderMixin and inherit from it with your order model.

6. Run python manage.py makemigrations and python manage.py migrate as usual.

7. Get form from your order by calling generate_credit_form in view:

   credit_form = order_object.generate_credit_form(request)

   And use it in your template:

   <form action="{{ credit_form.action }}" method="POST">
       {{ credit_form.as_p }}
       <input type="submit">
   </form>

8. Add SpgatewaySameSiteCookieMiddleware before SessionMiddleware to avoid SameSite cookie while return from payment gateway:

   MIDDLEWARE = [
       'django.middleware.security.SecurityMiddleware',
       'spgateway.middleware.SpgatewaySameSiteCookieMiddleware',
       'django.contrib.sessions.middleware.SessionMiddleware',
       'django.middleware.common.CommonMiddleware',
       ...
   ]

Example model

from spgateway.models import SpgatewayOrderMixin

class Order(SpgatewayOrderMixin, models.Model):
    total = models.IntegerField(default=0, verbose_name='Total Price')
    user = models.ForeignKey(User, verbose_name='Order by user')
    is_paid = models.BooleanField(default=False)

    # Add this parameter to let django-spgateway know which field is amount of price
    SpgatewayAmtFieldName = 'total'

    # Add this parameter to let django-spgateway set item description
    SpgatewayItemDesc = 'Items descriptions'

    # Add this method to let django-spgateway retrieve email
    def get_SpgatewayEmail(self, **kwargs):
        return self.user.email

    # Add this method let django-spgateway call when notify from Spgateway server
    # Change your order with this method
    def spgateway_notify(self, request, trade_info):
        status = trade_info['Status']
        status_msg = trade_info['Message']

        if status == 'SUCCESS':
            self.is_paid = True
            self.save()
        else:
            # TODO: Handle error

    # Add this method let django-spgateway call when client return from Spgateway server
    # Never trust data from client. Display messages only
    def spgateway_return(self, request, trade_info):
        status = trade_info['Status']
        status_msg = trade_info['Message']

        if status == 'SUCCESS':
            # TODO: Display success message to user
        else:
            # TODO: Display error message to user

    # django-spgateway will call this method to redirect user after user return from Spgateway server
    def get_absolute_url(self):
        return reverse('ORDER_DETAIL_VIEW_NAME_HERE')
