Course Discovery plugin for Tutor

Course Discovery plugin for Tutor

This is a plugin for Tutor that integrates the Course Discovery application in an Open edX platform. it is useful for integration with, for example, Ecommerce or an external course catalog.

This plugin was developed and open sourced to the community thanks to the generous support of E-ducation. Thank you!

Installation

This plugin requires tutor>=3.6.0. If you have installed tutor from a pre-compiled binary, it already comes bundled with the discovery plugin. Otherwise:

pip install tutor-discovery

Then, to enable this plugin, run:

tutor plugins enable discovery

You will have to re-generate the environment:

tutor config save

The, run migrations:

tutor local init

This last step is unnecessary if you run instead tutor local quickstart.

Operations

Creating a user

The discovery user interface will be available at http://discovery.local.overhang.io for a local test instance, and at DISCOVERY_HOST (by default: http(s)://discovery.<your lms host>) in production. In order to run commands from the UI, a user must be created:

tutor local run discovery ./manage.py createsuperuser

Then, you must login with this user at http://discovery.local.overhang.io/admin.

Alternatively, you can login with oauth2 using a pre-existing user created on the LMS/CMS by accessing http(s)://discovery.<your lms host>/login. To do so, the proper domain names must exist and point to the production server.

Index configuration

Discovery uses separate indices for different models (the names are: course, course_run, person and program by default). And you can overwrite theses names by configuring DISCOVERY_INDEX_OVERRIDES:

DISCOVERY_INDEX_OVERRIDES:
  course_discovery.apps.course_metadata.search_indexes.documents.course: your-course-index-name
  course_discovery.apps.course_metadata.search_indexes.documents.course_run: your-course-run-index-name
  course_discovery.apps.course_metadata.search_indexes.documents.person: your-person-index-name
  course_discovery.apps.course_metadata.search_indexes.documents.program: your-program-index-name

Re-indexing courses

tutor local run discovery ./manage.py refresh_course_metadata --partner_code=openedx
tutor local run discovery ./manage.py update_index --disable-change-limit

Caching programs

In order to cache programs in the LMS, you will need to manually create a catalog integration. This step should be performed just once:

tutor local run lms ./manage.py lms create_catalog_integrations --enabled \
    --internal_api_url="" \
    --service_username=lms_catalog_service_user

Then:

tutor local run lms ./manage.py lms cache_programs

This last step should be performed every time you create new or make changes to existing programs.

Debugging

To debug the course discovery service, you are encouraged to mount the course-discovery repo from the host in the development container:

tutor dev runserver -v ~/projets/openedx/repos/course-discovery/:/openedx/discovery discovery

You can then access the development server at http://discovery.local.overhang.io:8381. Feel free to add breakpoints (import pdb; pdb.set_trace()) anywhere in your source code to debug your application.

Alternatively, you may bind-mount a local course-discovery repository by adding the following to $(tutor config printroot)/env/dev/docker-compose.override.yml:

version: "3.7"
services:
    discovery:
        volumes:
            - /path/to/course-discovery/:/openedx/discovery

Once a local repository is mounted in the image, you will have to install nodejs dependencies and collect static assets:

tutor dev run discovery npm install --development
tutor dev run discovery make static.dev
