Needed models

sale code given by our system. - **operation_number**: bank operation
number. - **status**: status of the payment: “paid”, “pending”
(**pending** is mandatory) or “canceled”. - **amount**: amount to be
charged.

And the following methods: - **online_confirm**: mark the payment as
paid.

Needed views
--------------

Sale summary view
------------------

.. code:: python

    def payment_summary(request, payment_id):
        """
        Load a Payment object and show a summary of its contents to the user.
        """

        payment = get_object_or_404(Payment, id=payment_id, status="pending")
        replacements = {
            "payment": payment,
            # ...
        }
        return render(request, '<sale summary template path>', replacements)

Note that this payment summary view should load a JS file called
**set_payment_attributes.js**.

This file is needed to set initial payment attributes according to which
bank have the user selected.

Payment_confirm view
-------------------------

.. code:: python

    @csrf_exempt
    def payment_confirmation(request, virtualpos_type):
    	"""
    	This view will be called by the bank.
    	"""
    	# Directly call to confirm_payment view

    	# Or implement the following actions

    	# Checking if the Point of Sale exists
    	virtual_pos = VirtualPointOfSale.receiveConfirmation(request, virtualpos_type=virtualpos_type)

    	if not virtual_pos:
    		# The VPOS does not exist, inform the bank with a cancel
    		# response if needed
    		return VirtualPointOfSale.staticResponseNok(virtualpos_type)

    	# Verify if bank confirmation is indeed from the bank
    	verified = virtual_pos.verifyConfirmation()
    	operation_number = virtual_pos.operation.operation_number

    	with transaction.atomic():
    		try:
    			# Getting your payment object from operation number
    			payment = Payment.objects.get(operation_number=operation_number, status="pending")
    		except Payment.DoesNotExist:
    			return virtual_pos.responseNok("not_exists")

    		if verified:
    			# Charge the money and answer the bank confirmation
    			try:
    				response = virtual_pos.charge()
    				# Implement the online_confirm method in your payment
    				# this method will mark this payment as paid and will
    				# store the payment date and time.
    				payment.online_confirm()
    			except VPOSCantCharge as e:
    				return virtual_pos.responseNok(extended_status=e)
    			except Exception as e:
    				return virtual_pos.responseNok("cant_charge")

    		else:
    			# Payment could not be verified
    			# signature is not right
    			response = virtual_pos.responseNok("verification_error")

    		return response

Payment ok view
-------------------------

.. code:: python

    def payment_ok(request, sale_code):
        """
        Informs the user that the payment has been made successfully
        :param payment_code: Payment code.
        :param request: request.
        """

        # Load your Payment model given its code
        payment =  get_object_or_404(Payment, code=sale_code, status="paid")

        context = {'pay_status': "Done", "request": request}
        return render(request, '<payment_ok template>', {'context': context, 'payment': payment})

Payment cancel view
--------------------

.. code:: python

    def payment_cancel(request, sale_code):
        """
        Informs the user that the payment has been canceled
        :param payment_code: Payment code.
        :param request: request.
        """

        # Load your Payment model given its code
        payment =  get_object_or_404(Payment, code=sale_code, status="pending")
        # Mark this payment as canceled
        payment.cancel()

        context = {'pay_status': "Done", "request": request}
        return render(request, '<payment_canceled template>', {'context': context, 'payment': payment})


Refund view
-----------

.. code:: python

    def refund(request, tpv, payment_code, amount, description):
      	"""
      	:param request:
      	:param tpv: TPV Id
      	:param payment_code: Payment code
      	:param amount: Refund Amount (Example 10.89).
      	:param description: Description of refund cause.
      	:return:
      	"""

      	amount = Decimal(amount)

      	try:
      		# Checking if the Point of Sale exists
      		tpv = VirtualPointOfSale.get(id=tpv)
      		# Checking if the Payment exists
      		payment = Payment.objects.get(code=payment_code, state="paid")

      	except Payment.DoesNotExist as e:
      		return http_bad_request_response_json_error(message=u"Does not exist payment with code {0}".format(payment_code))

      	refund_status = tpv.refund(payment_code, amount, description)

      	if refund_status:
      		message = u"Refund successful"
      	else:
      		message = u"Refund with erros"

      	return http_response_json_ok(message)
