How-To

1. Common env.yaml file must have FEATURES:ALLOW_ALL_ADVANCED_COMPONENTS: True
2. Common env.yaml file must have ENABLE_RAPID_RESPONSE_AUTHOR_VIEW: True
3. Rapid-response package pip packages must be installed in the image rapid-response-xblock and ol-openedx-rapid-response-reports. Refer to existing package listings in the openedx docker configs.
4. In the LMS Admin UI -> /admin/lms_xblock/xblockasidesconfig/ create an enabled record.
5. In the CMS Admin UI -> /admin/xblock_config/studioconfig/ create an 'enabled' record.
6. Verify via studio on a test/demo course, find an existing multiple choice problem or create a new one. After creation in the 'unit view', you should now have a checkbox at the bottom of a multiple choice problem that will say 'Enable problem for rapid-response'.
