E-Commerce plugin for Tutor

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

⛔️ WARNING

e-commerce and e-commerce worker are under-maintained. The Open edX community is not fixing bugs or developing new features for it. We hope to deprecate and replace it soon. For updates, follow along on the DEPR ticket.

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:

tutor plugins install 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 launch again:

tutor local launch

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

tutor k8s launch

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
    flex_run_environment: cybersource.environment.sandbox
  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.

If you are running in production, you need to change the flex_run_environment value in the configuration file as well. You should change the flex_run_environment value to cybersource.environment.production

Operations

Creating a user

The ecommerce user interface will be available at http://ecommerce.local.edly.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.edly.io/admin/

To re-use an existing LMS user, first go to http://ecommerce.local.edly.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='[email protected]').update(is_staff=True, is_superuser=True)"

Make sure to replace [email protected] by the actual user email address. You should then be able to view the Oscar dashboard at http://ecommerce.local.edly.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.edly.io:8130.

To mount a local ecommerce repository in the ecommerce container, add an auto-mounted repository with:

tutor mounts add /path/to/ecommerce

Rebuild the "ecommerce" Docker image:

tutor images build ecommerce

Launch your platform again:

tutor dev launch

To attach a debugger to the ecommerce service, run:

tutor dev start ecommerce
