django-durationRel models a time-dependent relation between two django models.
In your models.py:
class MyModel(models.Model): pass class OtherModel(models.Model): mys = DurationField(MyModel)
See also tests/models.py and tests/tests.py.
You can run the tests from the parent dir with:
django-admin.py test --settings=django_durationRel.tests.settings
They're using a sqlite3 in-memory database.
To run the tests with test coverage first make sure you have coverage installed:
django-admin.py test --settings=django_durationRel.tests.coverage_settings
