Install and Start the E-Commerce Service#

Warning

This document is out of date regarding virtual environment configuration. E-Commerce should be properly provisioned for you as part of Dockerized devstack.

To install and start the edX E-Commerce service, you must complete the following steps.

Note

These steps assume that you are running Open edX devstack. If you prefer to run the E-Commerce service locally on your computer instead of on the virtual machine (VM) that devstack uses, see :Development Outside Devstack.

Set Up a Virtual Environment#

  1. Create or activate a Python virtual environment. You execute all of the commands described in this section within the virtualenv (unless otherwise noted).

    For more information, see Virtual Environments.

  2. Run the following command to install dependencies.

    $ make requirements

  3. (Optional) Create settings overrides that you do not commit to the repository. To do this, create a file named ecommerce/settings/private.py. The ecommerce/settings/local.py file reads the values in this file, but Git ignores the file.

Run Migrations#

To set up the ecommerce database, you must run migrations.

Note

Local installations use SQLite by default. If you use another database backend, make sure you update your settings and create the database, if necessary, before you run migrations.

  1. To run migrations, execute the following command.

    $ make migrate

When you run migrations, the E-Commerce service adds a default site to your installation.

Configure OAuth#

The E-Commerce service relies on the LMS, which serves as the OAuth 2.0 authentication provider.

To configure the E-Commerce service to work with OAuth, complete the following procedures.

Create and Register a Client#

To create and register a new OAuth client, follow these steps.

  1. Start the LMS.

  2. In your browser, go to http://127.0.0.1:8000/admin/oauth2_provider/application/.

  3. Select Add client.

  4. Leave the User field blank.

  5. For Client Name, enter E-Commerce Service.

  6. For URL, enter http://localhost:8002/.

  7. For Redirect URL, enter http://127.0.0.1:8002/complete/edx-oauth2/. This is the OAuth client endpoint.

    The system automatically generates values in the Client ID and Client Secret fields.

  8. For Client Type, select Authorization code.

  9. Enable Skip authorization.

  10. Select Save.

Configure a Site, Partner, and Site Configuration#

To finish creating and configuring your OAuth client, you must configure a partner, site, and site configuration for the E-Commerce service to use. The site that you configure is the default site that the E-Commerce service adds when you run migrations. You must update this default site to match the domain that you will use to access the E-Commerce service. You must also set up a site configuration that contains an oauth_settings JSON field that stores your OAuth client’s settings, as follows.

Setting

Description

Value

BACKEND_SERVICE_EDX_OAUTH2_KEY

OAuth 2.0 client key

The Client ID field in the Create and Register a Client section for backend server-to-server calls.

BACKEND_SERVICE_EDX_OAUTH2_SECRET

OAuth 2.0 client secret

The Client Secret field in the Create and Register a Client ection for backend server-to-server calls.

SOCIAL_AUTH_EDX_OAUTH2_KEY

OAuth 2.0 client key

The Client ID field in the Create and Register a Client section.

SOCIAL_AUTH_EDX_OAUTH2_SECRET

OAuth 2.0 client secret

The Client Secret field in the Create and Register a Client section.

SOCIAL_AUTH_EDX_OAUTH2_URL_ROOT

OAuth 2.0 authentication URL

For example, http://127.0.0.1:8000.

SOCIAL_AUTH_EDX_OAUTH2_ISSUER

OAuth token issuer

For example, http://127.0.0.1:8000.

SOCIAL_AUTH_EDX_OAUTH2_LOGOUT_URL

User logout URL

For example, http://127.0.0.1:8000/logout.

To configure your default site, partner, and site configuration, use the appropriate settings module for your environment (ecommerce.settings.devstack for Devstack, ecommerce.settings.production for Fullstack) to run the following Django management command. This command updates the default site and creates a new partner and site configuration with the specified options.

$ sudo su ecommerce
$ python manage.py create_or_update_site --site-id=1 --site-domain=localhost:8002 --partner-code=edX --partner-name='Open edX' --lms-url-root=localhost:8000 --theme-scss-path=sass/themes/edx.scss --payment-processors=cybersource,paypal --backend-service-client-id=[Change to OAuth Client ID for backend service calls] --backend-service-client-key=[Change to OAuth Client Secret for backend service calls] --sso-client-id=[Change to OAuth Client ID for SSO calls] --sso-client-key=[Change to OAuth Client Secret for SSO calls]

Add Another Site, Partner, and Site Configuration#

Start the Server#

To complete the installation and start the E-Commerce service, follow these steps.

Note

Local installations use SQLite by default. If you use another database backend, make sure you update your settings and create the database, if necessary, before you run migrations.

  1. (Devstack only) If you are using devstack, switch to the ecommerce user and use the ecommerce.settings.devstack settings module to run the following commands.

    $ sudo su ecommerce
$ make serve

  2. To run the server, execute the following command.

    $ python manage.py runserver 8002

    Note

    If you use a different port, make sure you update the OAuth client by using the Django administration panel in the LMS. For more information about configuring the OAuth client, see Configure OAuth.

Switch from ShoppingCart to E-Commerce#

By default, the ShoppingCart service is enabled when you install an Open edX instance. To use the E-Commerce service to handle ecommerce-related tasks instead of ShoppingCart, follow these steps.

  1. Sign in to the Django administration console for your base URL. For example, http://{your_URL}/admin.

  2. In the Commerce section, next to Commerce configuration, select Add.

  3. Select Enabled.

  4. Select Checkout on ecommerce service.

  5. (Optional) In the Single course checkout page field, override the default path value of /basket/single-item/ with your own path value.

    Important

    If you override the default path value, you must also change all of the code that relies on that path.

  6. Set the Cache Time To Live value in seconds.

  7. Select the site for which you want to enable the E-Commerce service.

  8. Select Save.

Development Outside Devstack#

If you are running the LMS in devstack but would prefer to run the E-Commerce service on your host, set up a reverse port-forward. This reverse port-forward allows the LMS process inside your devstack to use 127.0.0.1:8002 to make calls to the E-Commerce service running on your host. This simplifies LMS URL configuration.

To set up a reverse port-forward, execute the following command when you SSH into your devstack. Make sure that you run this command on the VM host, not the guest.

$ vagrant ssh -- -R 8002:127.0.0.1:8002
