Basic portable Directed Acyclic Graph application for Django
Django DAG ---------- .. Note: This is an unoffical 1.5.0 branch for Python 3 and Django2.2+ compatibility, every thing on this branch except the version number has either been pulle by elapso/django-dag or is an outstanding PR. (With the exception of the NodeOrdering, which iwll become a PR once we have unittests ) Ths version number has been bumped purely to aid the installation tools, and may not have all the features that the upstream 1.5.0 ends up with Django-dag is a small reusable app which implements a Directed Acyclic Graph. Usage ..... Django-dag uses abstract base classes, to use it you must create your own concrete classes that inherit from Django-dag classes. The `dag_test` app contains a simple example and a unit test to show you its usage. Example:: class ConcreteNode(node_factory('ConcreteEdge')): """ Test node, adds just one field """ name = models.CharField(max_length = 32) class ConcreteEdge(edge_factory(ConcreteNode, concrete = False)): """ Test edge, adds just one field """ name = models.CharField(max_length = 32, blank = True, null = True) Tests ..... Unit tests can be run with just django installed at the base directory by running `python manage.py test`
