edx-drf-extensions 8.6.0

edX extensions of Django REST Framework

Part of edX code.

edX Django REST Framework Extensions

This library includes various cross-cutting concerns related to APIs. API functionality added to this library must be required for multiple Open edX applications or multiple repositories.

Some of these concerns include extensions of Django REST Framework (DRF), which is how the repository initially got its name.

Publishing a Release

After a PR merges, a new version of the package will automatically be released by Travis when the commit is tagged. Use:

git tag -a X.Y.Z -m "Releasing version X.Y.Z"
git push origin X.Y.Z

Do not create a Github Release, or ensure its message points to the CHANGELOG.rst and ADR 0001-use-changelog.rst.

JWT Authentication and REST API Endpoints

JWT Authentication is the preferred method of authentication for Open edX API endpoints. See JWT Authentication README for more details.

CSRF API

One feature of this library is a csrf app containing an API endpoint for retrieving CSRF tokens from the Django service in which it is installed. This is useful for frontend apps attempting to make POST, PUT, and DELETE requests to a Django service with Django’s CSRF middleware enabled.

To make use of this API endpoint:

1. Install edx-drf-extensions in your Django project.

2. Add csrf.apps.CsrfAppConfig to INSTALLED_APPS.

3. Add 'edx_rest_framework_extensions.auth.jwt.middleware.JwtAuthCookieMiddleware' to MIDDLEWARE.

4. Add csrf.urls to urls.py.

How To Contribute

Contributions are very welcome.

Please read How To Contribute for details.

Even though they were written with edx-platform in mind, the guidelines should be followed for Open edX code in general.

Change Log

Unreleased

[8.6.0] - 2023-04-12

Added

• Added jwt_auth_check_symmetric_key, jwt_auth_asymmetric_verified, jwt_auth_symmetric_verified, and jwt_auth_verification_failed custom attributes to aid in deprecation and removal of symmetric keys.

• Added jwt_auth_issuer and jwt_auth_issuer_verification custom attributes.

Changed

• Changed jwt_auth_verify_keys_count custom attribute to aid in key rotations, to instead be jwt_auth_verify_asymmetric_keys_count and jwt_auth_verify_all_keys_count. The latter count is only used in the case that the token can’t be verified with the asymmetric keys alone.

[8.5.3] - 2023-04-11

Fixed

• (Hopefully) fixed the ability to publish edx-drf-extensions, by adding a long_description to setup.py. There was no real 8.5.1 or 8.5.2.

[8.5.0] - 2023-04-05

Added

• Added jwt_auth_verify_keys_count custom attribute to aid in key rotations

[8.4.1] - 2022-12-18

Added

• Additional logging in authenticate_credentials within the JWT authentication middleware for debugging purposes.

[8.4.0] - 2022-12-16

Added

• Added custom attribute enduser.id, following OpenTelemetry convention. This works with some New Relic automatic tooling around users. The old custom attribute request_user_id should be considered deprecated.

[8.3.1] - 2022-09-09

Fixed

• Fixed disabled user error by reverting change to JwtAuthentication.

[8.3.0] - 2022-09-07

Changed

• JwtAuthentication will fail for disabled users (with unusable password).

[8.2.0] - 2022-08-24

Added

• Added only asymmetric jwt decoding functionality in decoder

Changed

• Rename toggle_warnings to toggle_warning for consistency with setting_warning.

[8.1.0] - 2022-01-28

Dropped

• Dropped Support for Django22, 30, 31

[8.0.1] - 2021-11-01

Changed

• Resolve RemovedInDjango4.0 warnings.

[8.0.0] - 2021-09-30

Changed

• BREAKING CHANGE: Updated EnsureJWTAuthSettingsMiddleware to understand and work with permissions combined using DRF’s in-built support. This allows switching away from rest_condition. Any view that still uses rest_condition will cause the middleware to throw an error.

[7.0.1] - 2021-08-10

Fixed

• Removed dropped require_exp and require_iat options from jwt.decode and instead used require option with both exp and iat. For more info visit this: https://pyjwt.readthedocs.io/en/stable/changelog.html#dropped-deprecated-require-options-in-jwt-decode

• This fixes an error in previous release which had a multiple breaking changes

[7.0.0] - 2021-08-03

Changed

• BREAKING CHANGE: generate_jwt_token: Now returns string (instead of bytes), and no longer requires decoding. This was to keep consistent with change to jwt.encode in pyjwt upgrade (see below).

• BREAKING CHANGE: Upgraded dependency pyjwt[crypto] to 2.1.0, which introduces its own breaking changes that may affect consumers of this library. Pay careful attention to the 2.0.0 breaking changes documented in https://pyjwt.readthedocs.io/en/stable/changelog.html#v2-0-0.

[6.6.0] - 2021-07-13

Added

• Added support for django3.1 and 3.2

[6.5.0] - 2021-02-12

Added

• Added a new custom attribute jwt_auth_failed to both monitor failures, and to help prepare for future refactors.

[6.4.0] - 2021-01-19

Added

• Added a new custom attribute request_is_staff_or_superuser

[6.3.0] - 2021-01-12

Removed

• Drop support for Python 3.5

[6.2.0] - 2020-08-24

Updated

• Renamed “custom metric” to “custom attribute” throughout the repo. This was based on a decision (ADR) captured in edx-django-utils.

  • Deprecated RequestMetricsMiddleware due to rename. Use RequestCustomAttributesMiddleware instead.

[6.1.2] - 2020-07-19

Fixed

• _get_user_from_jwt no longer throws an UnsupportedMediaType error for failing to parse “new user” requests.

[6.1.1] - 2020-07-19

Fixed

• Latest drf-jwt is throwing error in case of any other Authorization Header. Fixing that issue in JwtAuthentication class.

[6.1.0] - 2020-06-26

Changed

• Update drf-jwt to pull in new allow-list(they called it blacklist) feature.

Added

Fixed

[6.0.0] - 2020-05-05

Changed

• BREAKING CHANGE: Renamed ‘request_auth_type’ to ‘request_auth_type_guess’. This makes it more clear that this metric could report the wrong value in certain cases. This could break dashboards or alerts that relied on this metric.

• BREAKING CHANGE: Renamed value session-or-unknown to session-or-other. This name makes it more clear that it is the method of authentication that is in question, not whether or not the user is authenticated. This could break dashboards or alerts that relied on this metric.

Added

• Added ‘jwt-cookie’ as new value for ‘request_auth_type_guess’.

• Added new ‘request_authenticated_user_found_in_middleware’ metric. Helps identify for what middleware step the request user was set, if it was set. Example values: ‘process_request’, ‘process_view’, ‘process_response’, or ‘process_exception’.

Fixed

• Fixed/Added setting of authentication metrics for exceptions as well.

• Fixed ‘request_auth_type_guess’ to be more accurate when recording values of ‘unauthenticated’ and ‘no-user’.
