Esegui i test di django-sedano su Django 1.8

Question

In definitiva, voglio passare i test per Django 1.9. django-celery attualmente funziona con Django < 1.9. Quindi il primo passo è fare in modo che i test della libreria passino con Django 1.8 sulla mia macchina.

Ho clonato https://github.com/celery/django-celery in un progetto di test e installato i requisiti. Per Django 1.7 i test stanno passando. Per Django 1.8 sto ottenendo lo stesso errore più volte mentre dovrebbe funzionare ...

Vedi https://github.com/celery/django-celery/blob/master/tox.ini comprende Django 1.8:

... 
1.8: Django>=1.8.0,<1.9.0 

---

per Django 1.7:

pip install Django==1.7 
./django-celery/tests/manage.py test djcelery.tests 
... 
Ran 64 tests in 0.319s 
OK 

---

Per Django 1.8:

pip install Django==1.8 
./django-celery/tests/manage.py test djcelery.tests 

...

Cosa mi manca?

Django 1.8 ha avuto un cambiamento di API che impedisce l'aggiunta di casi modello non salvati come ForeignKey: https://docs.djangoproject.com/en/1.8/releases/1.8/#assigning-unsaved-objects-to-relations-raises-an-error
