an app that aggregates block level completion data for different block types for Open edX.

Project description

PyPI Travis Codecov Documentation Supported Python versions License

openedx-completion-aggregator is a Django app that aggregates block level completion data for different block types for Open edX.


openedx-completion-aggregator uses the pluggable django app pattern to ease installation. To use in edx-platform, do the following:

  1. Install the app into your virtualenv.


    $ pip install openedx-completion-aggregator
  2. [Optional] You may override the set of registered aggregator block types in your lms.env.json file:

  3. By default, completion is aggregated with each created or updated BlockCompletion. If this creates too much database activity for your installation, set the following in your lms.env.json file:


    Then configure up a pair of cron jobs to run ./ run_aggregator_service and ./ run_aggregator_cleanup as often as desired.

Note that if operating on a Hawthorne-or-later release of edx-platform, you may override the settings in EDXAPP_ENV_EXTRA instead.
