Thank you for reporting this @stefanfoulis! I am not currently running this app on Django 1.8.

My suggestion for you or anyone who would like to update this app to work with 1.8:

• Update the tox.ini file to add py27-1.8, py33-1.8, or py34-1.8 (both at the top of the file and as a new section in the file)
• Run the tests (see contributing file)
• Fix one test at a time

Hi...

I fixed some tests and a library part. I also added a test project that can help improve error in Django 1.8 / 1.9.

fizista@69abfe9

Unfortunately I do not have time to correct these tests:

ERROR: test_foreign_keys (relatives.tests.tests.RelatedObjectsTagTest)
ERROR: test_many_to_many (relatives.tests.tests.RelatedObjectsTagTest)
ERROR: test_no_admin_url (relatives.tests.tests.RelatedObjectsTagTest)
FAIL: test_add_form_for_non_nullable_fk (relatives.tests.tests.TemplateFilterTest)
FAIL: test_nullable_foreign_key (relatives.tests.tests.TemplateFilterTest)

Maybe someone will find time to complete the code migration to new versions of Django.

I also added a test site, making it easier to probably complete the migration:

cd relatives/tests/
./manage.py migrate
./manage.py createsuperuser --username admin --email admin@example.com
./manage.py runserver
