This is a placeholder payment processor for the Ecommerce application from Open edX.
This plugin was bootstraped by eduNEXT and implemented by the NAU FCCN team to work specifically with the Tutor Open edX distribution. The following installation instructions should work wit the tutor-ecommerce plugin, but there is no reason to believe that it shouldn't also work with the Open edX native installation.
This guide is based in the openedx-saferpay README.
Other projects that this project receive inspiration: - https://github.com/epfl-cede/openedx-saferpay - https://github.com/nelc/ecommerce-hyperpay - https://github.com/eduNEXT/ecommerce-extensions/tree/ee25624582c8e42b7eb998fda54358a7025c2dce/ecommerce_extensions/payment/processors - https://github.com/open-craft/ecommerce-paytabs
Install the following version of tutor-ecommerce as it contains special code to avoid the usage of discovery service for development purposes:
pip install git+https://github.com/eduNEXT/tutor-ecommerce@nau/v14.0.1#egg=tutor-ecommerce==v14.0.1
Make sure that the ecommerce plugin is enabled:
tutor plugins enable ecommerce
Make sure that the discovery and mfe plugins are disabled:
tutor plugins disable mfe tutor plugins disable discovery
Add the PayGate payment processor to the Docker image:
tutor config save \
--set 'ECOMMERCE_EXTRA_PIP_REQUIREMENTS=["https://github.com/fccn/ecommerce-plugin-paygate"]'
tutor images build ecommerce
Then configure your Ecommerce instance to use the PayGate payment processor:
tutor config save --set 'ECOMMERCE_ENABLED_PAYMENT_PROCESSORS=["paygate"]'
tutor config save --set 'ECOMMERCE_EXTRA_PAYMENT_PROCESSOR_CLASSES=["paygate.processor.PayGate"]'
tutor config save --set 'ECOMMERCE_EXTRA_PAYMENT_PROCESSOR_URLS={"paygate": "paygate.urls"}'
Save your PayGate credentials to paygate.yml:
$ cat paygate.yml
paygate:
access_token: PwdX_XXXX_YYYY
merchant_code: NAU
api_checkout_url: https://lab.optimistic.blue/paygateWS/api/CheckOut
api_checkout_req_timeout_sec: 10 # optional
api_back_search_transactions: https://lab.optimistic.blue/paygateWS/api/BackOfficeSearchTransactions
api_back_search_transactions_timeout_seconds: 10 # optional
api_basic_auth_user: username
api_basic_auth_pass: password
cancel_checkout_path: /checkout/cancel-checkout/ # optional
error_path: /checkout/error/ # optional
title: PayGate # optional
payment_types: ["VISA", "MASTERCARD", "AMEX", "PAYPAL", "MBWAY", "REFMB", "DUC"]
$ tutor config save --set "ECOMMERCE_PAYMENT_PROCESSORS=$(cat paygate.yml)"
The `cancel_checkout_path` and `error_path` are optional.
Run initialization scripts:
tutor local quickstart
Enable the PayGate payment backend:
tutor local run ecommerce ./manage.py waffle_switch --create payment_processor_active_paygate on
All payments will then proceed through the PayGate payment processor.
Next, it is described the instructions to run the development environmen using the Open edX Devstack.
If you are using some internal FCCN IaaS VM, please use FCCN forked Devstack for that Open edX release.
If the service frontend-app-payment didn't start and has this on the docker logs:
sh: 1: fedx-scripts: not found
The reason was because the npm install were raising some error:
Invalid tag name ">=^16.0.0" of package "react@>=^16.0.0": Tags may not have any characters that encodeURIComponent encodes.
To fix run this inside the container:
npm install --legacy-peer-deps
To develop using the devstack edit the ecommerce/settings/private.py file add change to:
PAYMENT_PROCESSOR_CONFIG = {
"edx": {
"paygate": {
"access_token": 'PwdX_XXXX_YYYY',
"merchant_code": "NAU",
"api_checkout_url": 'https://lab.optimistic.blue/paygateWS/api/CheckOut',
"api_basic_auth_user": "NAU",
"api_basic_auth_pass": "APassword",
"payment_types": ["VISA", "MASTERCARD", "AMEX", "PAYPAL", "MBWAY", "REFMB", "DUC"]
}
}
}
PAYMENT_PROCESSORS = ("paygate.processors.PayGate",)
EXTRA_PAYMENT_PROCESSOR_URLS = {"paygate": "paygate.urls"}
OSCAR_DEFAULT_CURRENCY = 'EUR'
LANGUAGE_CODE = "pt"
from django.utils.translation import ugettext_lazy as _
LANGUAGES = (
('pt-pt', _('Português')),
('en', _('English')),
)
LOGO_URL = "https://lms.nau.edu.pt/static/nau-basic/images/nau_azul.svg"
# Use custom tax strategy
NAU_EXTENSION_OSCAR_STRATEGY_CLASS = "ecommerce_plugin_paygate.strategy.DefaultStrategy"
# Configure tax as 23% used in Portugal
NAU_EXTENSION_TAX_RATE = "0.298701299" # = 0.23/0.77
Clone the repository https://github.com/fccn/ecommerce-plugin-paygate to the src folder of the devstack (the parent src folder of the devstack folder)
Install this plugin inside the ecommerce container:
make dev.shell.ecommerce pip install -e /edx/src/ecommerce-plugin-paygate
Restart ecommerce application:
make dev.restart-container.ecommerce
On the Open edX Ecommerce user interface it is need to activate the PayGate payment processor. To activate the paygate add switch with the name payment_processor_active_paygate on http://localhost:18130/admin/waffle/switch/.
On ecommerce Django admin site configuration, http://localhost:18130/admin/core/siteconfiguration/1/change/ - disable Microfrontend for Basket Page - replace payment processors from cybersource,paypal to paygate
- To run the tests and linting inside the Ecommerce container using Devstack run::
- make -C /edx/src/ecommerce-plugin-paygate/ test lint
There are different callbacks that the PayGate uses. The success, cancel and failure callbacks are used to redirect the user after he has payed with success, has cancel the payment inside the PayGate user interface or some error has been raised.
Additionally, there is also a server-to-server callback, the PayGate calls the Ecommerce informing that some payment reference has been payed.
Example of the server callback, change the payment_ref with your basked identification:
curl -d '{"statusCode":"C", "success":"true", "MerchantCode":"NAUFCCN", "returnCode":"ABCDEFGHI", "shortMsg":"Opera%C3%A7%C3%A3o%20bem%20sucedida", "name": "edx", "is_paid": "true", "paymentValue": "1.00", "payment_ref": "EDX-100019"}' -H "Content-Type: application/json" -X POST http://localhost:18130/payment/paygate/callback/server/
To make the isort work properly inside the Visual Studio Code, you should add this to your Workspace settings JSON:
"isort.args":["--settings-file", "<path to ecommerce project on host>/.isort.cfg"],
