Release 2.1.3

Python 3 Support

  • Python 3 officially supported in Tethys Platform.

  • Python 2 support officially deprecated and will be dropped when Tethys Platform 3.0 is released.

  • Tethys needs to migrate to Python 3 only so we can upgrade to Django 2.0, which only supports Python 3.

Important

Migrate your apps to Python 3. After Tethys Platform 3.0 is released, Python 2 will no longer be supported by Tethys Platform.

100% Unit Test Coverage

  • Tests pass in Python 2 and Python 3.

  • Unit tests cover 100% of testable code.

  • Code base linted using flake8 to enforce PEP-8 and other Python coding best practices.

  • Automated test execution on Travis-CI and Stickler-CI whenever a Pull Request is submitted.

  • Added badges to the README to display build/testing, coverage, and docs status on github repository.

  • All of this will lead to increased stability in this and future releases.

See: Tethys Platform Repo for build and coverage information.

Tethys Extensions

  • Create your own gizmos.

  • Centralize app logic that is common to multiple apps in an extension.

Class-based Controllers

  • Added TethysController to SDK to support class-based views in Tethys apps.

  • Inherits from django View class.

  • Includes as_controller method, which is a thin wrapper around as_view method to better match Tethys terminology.

  • UrlMaps can take class-based Views as the controller argument: MyClassBasedController.as_controller(...)

  • More to come in the future.
