Directed Acyclic Graph implementation for Django 1.6+

Project description

Django-dag is a small reusable app which implements a Directed Acyclic Graph.


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.


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)


Unit tests can be run with just django installed at the base directory by running
python test
