completion

Purpose

A library for tracking completion of blocks by learners in Open edX courses.

This repository provides a Django model BlockCompletion that is intended to be plugged into edx-platform. It provides various handlers and services for the recording of completion data. It also provides a DRF API for submitting completion data in batches.

Enabling in the LMS

By default, the Open edX LMS does not use this library. To turn it on, go to , and add a new switch with Name completion.enable_completion_tracking and Active selected.

See Completion Tool in the Open edX documentation for details on what will happen once enabled.

Getting Started with Development

Please see the Open edX documentation for guidance on Python development in this repo.

To install the completion app, run these commands from the completion root directory:

pip install -e

To run the test suite:

pip install tox
tox # to run only a single environment, do e.g. tox -e py312-django42-drflatest

To use a Django shell to test commands:

make install
python manage.py migrate
python manage.py shell
>>> from completion.models import BlockCompletion
>>> 

Deploying

Tagged versions of the completion library are released to pypi.org.

To use the latest release in your project, add the following to your pip requirements file:

edx-completion

[4.4.1] - 2023-10-27

• Fix RemovedInDjango41Warning by removing django_app_config

[4.4.0] - 2023-10-20

• Added tracking logs for completion events

[4.3.0]- 2023-07-26

• Added support for Django 4.2

[4.2.1]- 2023-04-26

• Support get_child_blocks along with get_child_descriptors.
• Switch from edx-sphinx-theme to sphinx-book-theme since the former is deprecated

[4.1.0]- 2021-07-19

• Add Django 3.0, 3.1 & 3.2 Support

[4.0.4]- 2021-02-04

• Update get_key_to_last_completed_block to return full_block_key instead of block_key

[4.0.2] - 2021-02-04

• Future-proof usage of edx_toggles.toggles

[4.0.1] - 2021-01-05

• Replace reference to deprecated import path student.models with common.djangoapps.student.models.
• Updated the build status badge in README.rst to point to travis-ci.com instead of travis-ci.org

[4.0.0] - 2020-11-05

• Remove soon-to-be-deprecated WaffleSwitchNamespace class instances
• BACKWARD INCOMPATIBLE: Removes waffle(), which returned a (now deprecated) WaffleSwitchNamespace. This should only affect tests in edx-platform.
• Requires edx-toggles>=1.2.0, which introduces a new API to waffle objects.
• Refactors ENABLE_COMPLETION_TRACKING_SWITCH from a LegacyWaffleSwitch to the updated WaffleSwitch. We don't expect uses of this updated switch to require changes, unless there are surprise uses of deprecated methods from LegacyWaffleSwitch.

[3.2.5] - 2020-10-23

• Fix waffle switch override in tests by relying on newest edx_toggles API

[3.2.4] - 2020-07-21

• Fix AttributeError raised by vertical_is_complete.
  • by ensuring get_completable_children doesn't return null

[3.2.3] - 2020-07-01

• Updated the children lookup for vertical_is_complete to utilize the XBlockCompletion model. There are three completion modes to consider: EXCLUDED, AGGREGATOR, COMPLETABLE.
  • This method will now ignore any block with XBlockCompletion.EXCLUDED.
  • This method will now recurse down any child of a vertical if that child has XBlockCompletion.AGGREGATOR.
  • This method will consider all children blocks with XBlockCompletion.COMPLETABLE as candidates to determine if the vertical is complete.

[3.2.2] - 2020-06-30

• Adding recursive lookup for children of a vertical to the vertical_is_complete method in services.py.
  • This was added because verticals containing children that had their own children were not being properly marked as complete. Since the vertical was only looking one layer deep, it was possible to have children lower in the tree incomplete, but the vertical would still be marked as complete. Now it looks at all leaves under the vertical.

[3.1.1] - 2020-02-24

• Remove unnecessary constraint for edx-drf-extensions<3.0.0

[3.1.0] - 2020-02-18

• Upgrades packages, drops support for Python 2.

[3.0.1] - 2019-10-22

• Fix the package long description to be valid rST, check this in CI.

[3.0.0] - 2019-10-22

• Support tracking completion of XBlocks in any "learning context", such as in a content library, and not just in courses. To keep the code clean, this has been done as a breaking change to the python API. (The API has been simplified so that it's generally only necessary to pass in a block key / usage key rather than block key + course key.) The REST API is unchanged.

[2.1.1] - 2019-10-21

• Updated credentials for PyPI deployment via token.

[2.1.0] - 2019-10-18

• Switch blocks_to_mark_complete_on_view() to return a list of XBlocks instead of a set. Many XBlocks aren't hashable; the old implementation allowed subtle bugs under Python 2.7 but triggers an immediate error under 3.5.

[2.0.0] - 2019-04-23

• Unpin django-rest-framework requirements. This is a potentially breaking change if people were relying on this package to ensure the correct version of djangorestframework was being installed.
• Remove the AUTHORS file and references to it.

[1.0.2] - 2019-03-11

• Fix the 403 error occurring for completion-batch API for requests coming from the iOS devices

[1.0.0] - 2018-10-16

• Updated edx-drf-extensions imports. Completion will no longer work with outdated versions of edx-drf-extensions.

[0.1.14] - 2018-10-04

• Added submit_completion and submit_group_completion methods on CompletionService.

[0.1.7] - 2018-06-18

• Added can_mark_block_complete_on_view() and blocks_to_mark_complete_on_view() methods on CompletionService and renamed get_completion_by_viewing_delay_ms() to get_complete_on_view_delay_ms().

[0.1.6] - 2018-04-13

• Remove usage of deprecated CourseStructure api.

[0.1.5] - 2018-04-03

• Delete enable_visual_progress methods and checks. Deprecate ENABLE_VISUAL_PROGRESS, ENABLE_COURSE_VISUAL_PROGRESS, and ENABLE_SITE_VISUAL_PROGRESS waffle flags

[0.1.4] - 2018-03-28

• Site configurations must now explicitly disable visual progress for the enable_visual_progress() feature gating function to return False early.

[0.1.3] - 2018-03-26

• Added some documentation.

[0.1.2] - 2018-03-23

• Fix management of dependency versions

[0.1.1] - 2018-03-23

• Fixes wildly inefficient raw query in BlockCompletion.latest_blocks_completed_all_courses()
• Updates freezegun version, makes tests that use it somewhat faster.

[0.1.0] - 2018-03-20

• Fixes

[0.0.11] - 2018-03-20

• Added "subsection-completion/{username}/{course_key}/{subsection_id}" API endpoint, to be used with the completion milestones experiment.

[0.0.9] - 2018-02-27

• Added "utilities.py", which houses methods for working with BlockCompletion data.

[0.0.8] - 2018-03-01

• Add model method for superlative “last completed block” - for site awareness include every last completed block by course, for later sorting in business layer.

[0.0.7] - 2018-02-15

• Add settings and service method for determining completion-by-viewing delay.

[0.0.6] - 2018-02-13

• Add the additional completion logic into the service and models from edx-platform

[0.0.2] - 2018-01-31

• Fix up edx-lint requirements shenanigans.
