Description

1. Add atol to your INSTALLED_APPS setting like this:

   INSTALLED_APPS = [
       ...
       'atol',
   ]
   

2. Add atol settings like this:

   RECEIPTS_ATOL_LOGIN = 'login'
   RECEIPTS_ATOL_PASSWORD = 'secret'
   RECEIPTS_ATOL_GROUP_CODE = 'ATOL-ProdTest-1'
   RECEIPTS_ATOL_TAX_NAME = 'vat18'
   RECEIPTS_ATOL_INN = '112233445573'
   RECEIPTS_ATOL_CALLBACK_URL = None
   RECEIPTS_ATOL_PAYMENT_ADDRESS = 'г. Москва, ул. Оранжевая, д.22 к.11'
   RECEIPTS_OFD_URL_TEMPLATE = u'https://lk.platformaofd.ru/web/noauth/cheque?fn={fn}&fp={fp}'
   

3. Include the atol URLconf in your project urls.py like this:

   from atol.views import ReceiptView
   
   url(r'^r/(?P<short_uuid>[\w]+)/$', ReceiptView.as_view(), name='receipt')
   

4. Run python manage.py migrate atol to create the receipt model.

5. Add payment_accept signal and init_receipt receiver:

   payment_accepted = Signal(providing_args=['payment'])
   
   @receiver(payment_accepted)
   @transaction.atomic
   def init_payment_receipt(sender, payment, **kwargs):
   
       ...
   
       receipt = Receipt.objects.create(
           user_email=payment.user.email,
           purchase_price=payment.amount
       )
       payment.receipt = receipt
       payment.save(update_fields=['receipt'])
       transaction.on_commit(
           lambda: atol_create_receipt.apply_async(args=(receipt.id,), fallback_sync=True)
       )
