Django Workflow Library
Contributors are welcome. Come and give a hand :-)
River is an open source workflow framework for Django which support on the fly changes instead of hardcoding states, transitions and authorization rules.
The main goal of developing this framework is to be able to edit any workflow item on the fly. This means that all the elements in a workflow like states, transitions or authorizations rules are editable at any time so that no changes requires a re-deploying of your application anymore.
Playground: There is a fake jira example repository as a playground of django-river. https://github.com/javrasya/fakejira
Online documentation is available at http://django-river.rtfd.org/.
- Python (2.7, 3.4, 3.5, 3.6)
