Installation

1. Install via pip:

   pip install django-payu-payments
   

2. Add payu to INSTALLED_APPS:

   INSTALLED_APPS = [
       ...
       'payu',
       ...
   ]
   

3. Add URLs to URLConf:

   url(r'^payments/', include('payu.urls', namespace='payu')),
   

4. Run migrations:

   python manage.py migrate
   

Configuration

Configuration is done via Django's settins.py file.

• PAYU_POS_ID

  Your POS ID. If not provided the test payment value will be used.

• PAYU_MD5_KEY

  Your MD5 key. If not provided the test payment value will be used.

• PAYU_SECOND_MD5_KEY

  Your second MD5 key. If not provided the test payment value will be used.

• PAYU_CONTINUE_PATH

  Specifies path on your website, where user should be redirected after payment (successful, or not). May be absolute path, like /some-page/ or reverse('some:thing'). This view should handle GET parameters error=501 in case of failed payment and no_payment=1 in case of payment with total equals 0, which is registered, but actually sent to PayU.

• PAYU_VALIDITY_TIME

  Payment validity time (in seconds), after which it's canceled, if user did not take action. If not provided 600 will be used.

Create payment

To create payment object you have to call Payment.create method:

from payu.models import Payment


description = 'Some stuff'
products = [
    {
        'name': 'Some product',
        'unitPrice': 14.99,
        'quantity': 1
    },
    {
        'name': 'Some other product',
        'unitPrice': 3.19,
        'quantity': 4
    }
]
buyer = {
    'email': '[email protected]',
    'firstName': 'John',
    'lastName': 'Doe'
}
notes = 'This client is important for us, we should prioritize him.'

payment = Payment.create(request, description, products, buyer, validity_time=300, notes)

request is just Django HTTP request object, we need it to get buyer IP, and absolute URLs.

validity_time is optional and overrides PAYU_VALIDITY_TIME setting.

notes is optional, and used for storing internal information about payment.

Payment.create will return two-key dictionary, containing Payment object and URL where buyer should be redirected, or False if not successful.

{
    'object': <Payment object>,
    'redirect_url': 'https://...'
}

Fetch payment's data

To get data associated with payment you just need to retrieve Payment object:

Payment.objects.get(...)

There are also few helpful methods, which you can call on Payment object:

• get_total_display()

  Returns pretty formatted total value.

• get_products_table()

  Returns pretty formatted table of products associated with payment.

• is_successful()

  For status equal COMPLETED returns True, otherwise False.

• is_not_successful()

  For status equal CANCELED or REJECTED returns True, otherwise False.
