A Tutor plugin for Open edX E-Commerce

Project description

This is a plugin for Tutor that integrates the E-Commerce application in an Open edX platform.

Installation

This plugin requires tutor>=12.0.0, the Discovery plugin and the MFE plugin. If you have installed Tutor by downloading the pre-compiled binary, then both plugins should be automatically installed. You can confirm by running:

tutor plugins list

But if you have installed tutor from source, then you also need to install the plugin from source:

pip install tutor-ecommerce

Then, in any case you need to enable the plugins:

tutor plugins enable discovery ecommerce mfe

Services will have to be re-configured and restarted, so you are probably better off just running quickstart again:

tutor local quickstart

Note that this plugins is compatible with Kubernetes integration. When deploying to a Kubernetes cluster, run instead:

tutor k8s quickstart

For further instructions on how to setup E-Commerce with Open edX, check the official E-Commerce documentation.

Configuration

  • ECOMMERCE_HOST (default: "ecommerce.{{ LMS_HOST }}")
  • ECOMMERCE_PAYMENT_PROCESSORS (default: {cybersource: {...}, paypal: {...}} See below for details.)
  • ECOMMERCE_ENABLE_IDENTITY_VERIFICATION: (default: True)
  • ECOMMERCE_ENABLED_PAYMENT_PROCESSORS: (default: ["cybersource", "paypal"])
  • ECOMMERCE_ENABLED_CLIENT_SIDE_PAYMENT_PROCESSORS (default: ["cybersource"])
  • ECOMMERCE_EXTRA_PAYMENT_PROCESSOR_CLASSES (default: [])
  • ECOMMERCE_MYSQL_PASSWORD: "{{ 8|random_string }}")
  • ECOMMERCE_SECRET_KEY (default: "{{ 20|random_string }}")
  • ECOMMERCE_OAUTH2_SECRET (default: "{{ 8|random_string }}")
  • ECOMMERCE_API_KEY (default: "{{ 20|random_string }}")
  • ECOMMERCE_DOCKER_IMAGE (default: "{{ DOCKER_REGISTRY }}overhangio/openedx-ecommerce:{{ TUTOR_VERSION }}")
  • ECOMMERCE_WORKER_DOCKER_IMAGE (default: "{{ DOCKER_REGISTRY }}overhangio/openedx-ecommerce-worker:{{ TUTOR_VERSION }}")
  • ECOMMERCE_MYSQL_DATABASE (default: "ecommerce")
  • ECOMMERCE_MYSQL_USERNAME (default: "ecommerce")
  • ECOMMERCE_CURRENCY (default: "USD")
  • ECOMMERCE_OAUTH2_KEY (default: "ecommerce")
  • ECOMMERCE_API_TIMEOUT (default: 5)
  • ECOMMERCE_WORKER_JWT_ISSUER (default: "ecommerce-worker")
  • ECOMMERCE_EXTRA_PIP_REQUIREMENTS (default: [])

You will need to modify the ECOMMERCE_PAYMENT_PROCESSORS parameter to configure your payment providers credentials. By default, it is equal to:

cybersource:
    merchant_id: SET-ME-PLEASE
    flex_shared_secret_key_id: SET-ME-PLEASE
    flex_shared_secret_key: SET-ME-PLEASE
    soap_api_url: https://ics2wstest.ic3.com/commerce/1.x/transactionProcessor/CyberSourceTransaction_1.140.wsdl
    transaction_key: SET-ME-PLEASE
  paypal:
    cancel_checkout_path: /checkout/cancel-checkout/
    client_id: SET-ME-PLEASE
    client_secret: SET-ME-PLEASE
    error_url: /checkout/error/
    mode: sandbox
    receipt_url: /checkout/receipt/

We suggest you modify this configuration, save it to ecommerce-config.yml and then load it with:

tutor config save --set "ECOMMERCE_PAYMENT_PROCESSORS=$(cat ecommerce-config.yml)"

Cybersource

To enable the Cybersource payment processor, two keys need to be generated. In your Cybersource account, go to “Payment Configuration” 🠆 “Key Management” 🠆 “Generate key”. Create the following keys:

  • SOAP API key: use this key to define the transaction_key setting.
  • REST Shared secret: use the key ID and value to define flex_shared_secret_key_id and flex_shared_secret_key, respectively.

The merchant_id setting corresponds to your Merchant ID.

Operations

Creating a user

The ecommerce user interface will be available at http://ecommerce.local.overhang.io for a local instance, and at ECOMMERCE_HOST (by default: http(s)://ecommerce.<yours lms host>) in production. In order to run commands from the UI, a user with admin rights must be created. There are two ways to proceed. To create a brand new user in E-Commerce which will not exist in the LMS, run:

tutor local run ecommerce ./manage.py createsuperuser

Then login with this new user at: http://ecommerce.local.overhang.io/admin/

To re-use an existing LMS user, first go to http://ecommerce.local.overhang.io/login. You should be redirected to the LMS login page, then to the dashboard. Then this user must be made a staff/superuser in E-Commerce:

tutor local run ecommerce ./manage.py shell -c "from django.contrib.auth import get_user_model; get_user_model().objects.filter(email='USER@EMAIL.COM').update(is_staff=True, is_superuser=True)"

Make sure to replace USER@EMAIL.COM by the actual user email address. You should then be able to view the Oscar dashboard at http://ecommerce.local.overhang.io.

Custom payment processors

⚠️ WARNING: as of Lilac (Tutor v12), Open edX no longer supports custom payment processors with E-Commerce. There is an ongoing conversation about how to resolve this issue which you can follow here.

Image customisation

E-Commerce implementations vary a lot from one country to another. If all you need are the Paypal, Cybersource and Stripe payment processors, then it should not be necessary to customize the tutor-ecommerce docker image, which contains the vanilla E-Commerce platform. However, if you need to run a fork of E-Commerce, or install extra requirements, then you should re-build the docker image. To do so, first set the appropriate settings:

tutor config save \
  --set 'ECOMMERCE_EXTRA_PIP_REQUIREMENTS=["git+https://github.com/myusername/myplugin"]'

Then, build the image, pointing to your fork if necessary:

tutor images build ecommerce \
  -a ECOMMERCE_REPOSITORY=https://github.com/myusername/ecommerce \
  -a ECOMMERCE_VERSION=my/tag

Development

When running Tutor in development mode, the ecommerce service is accessible at http://ecommerce.local.overhang.io:8130.

To mount a local ecommerce repository in the ecommerce container, add the following content to the $(tutor config printroot)/env/dev/docker-compose.override.yml file:

version: "3.7"
services:
  ecommerce:
    volumes:
      - /absolute/path/to/ecommerce:/openedx/ecommerce

You will have to generate static assets in your local repository:

tutor dev run ecommerce npm install
tutor dev run ecommerce ./node_modules/.bin/bower install --allow-root
tutor dev run ecommerce python3 manage.py update_assets --skip-collect

To attach a debugger to the ecommerce service, run:

tutor dev runserver ecommerce
