6.8.5. Gating E-Commerce Service Features#

You can release new E-Commerce service features and functionality behind a feature gate. This project uses the Waffle library for feature gating.

6.8.5.1. Types of Feature Gates#

Waffle supports the following types of feature gates.

Flag: This gate allows you to enable a feature for specific users, groups, users who meet certain criteria (such as authenticated users or staff), or a certain percentage of visitors.
Switch: This gate is a Boolean that turns a feature on or off for all users.
Sample: This gate allows you to define the probability with which a given feature will be on.

For more information about creating or updating features and feature gates, see the Waffle documentation.

Waffle offers the following feature gates.

Name	Type	Purpose
user_enrollments_on_dashboard	Switch	Display a user’s current enrollments on the dashboard user detail page.
publish_course_modes_to_lms	Switch	Publish prices and SKUs to the LMS after every course modification.
async_order_fulfillment	Sample	Specify what percentage of orders are fulfilled asynchronously.
ENABLE_CREDIT_APP	Switch	Enable the credit checkout page, from which learners can purchase credit in a course.
ENABLE_NOTIFICATIONS	Switch	Enable email notifications for a variety of user actions, such as when an order is placed.
PAYPAL_RETRY_ATTEMPTS	Switch	Enable users to retry unsuccessful PayPal payments.

If you want to make a feature permanent, remove its feature gate from relevant code and tests, and delete the gate from the database.
